The download is only available for AutoCAD 2009, AutoCAD Revit Architecture Suite 2009, and AutoCAD Revit Structure Suite 2009. Of course it is also only available to subscription customers.
To get this "Bonus Pack", log in to the subscription center and a link should be listed on the front page.
PDF Attach
The new command for attaching a PDF is named PDFATTACH. You can also use the right-click menu in the External References palette. If you attach a vector PDF, you can use object snaps to snap to geometry in the PDF file. This is controlled by the PDFOSNAP system variable. If the PDF contains layer information, use the PDFLAYERS command for on/off control.
You can use the PDFCLIP command to perform clipping operations on the PDF. The frame outline on an attached PDF is controlled by the PDFFRAME system variable. You can adjust the visible properties of the PDF including fade and contrast by using the PDFADJUST command.
PDF Output
A new PC3 file named DWG to PDF Bonus Pack.PC3 is created that includes the enhancements. These enhancements include increased resolution. The readme file recommends a setting of at least 600dpi. TrueType fonts are now embedded instead of converted to graphics. This should reduce file sizes of the PDF files.
Merge control settings are also available in this new driver. This is the "Lines Merge" vs. "Lines Overwrite" setting. You can include layer information in the output PDF now, and automatically display the finished PDF in your PDF viewer when the plot command is finished.
Summary
These are two welcome additions. A quick run through of each feature produced positive results.
It's a shame that this "Bonus Pack" is only for subscription customers. The enhancements to the PDF plot driver should have been included in the initial release in AutoCAD 2007 since these are basic requirements. The PDF attachment feature has been at or near the top of the AUGI wish list for a long time now. Unfortunately, non-subscription users will have to keep wishing for now.

In a previous post from April 2008, I had a link to DWG TrueConvert 2007. That URL actually pointed to DWG Trueconvert 2004. I don't know if Autodesk changed the target of that URL or what. Here are the current links as of today:
- DWG Trueconvert 2007 (33.1MB)
- DWG Trueconvert 2004 (18.9MB)

With regard for the subject, I ran into my #1 pet peeve again today, SCALED DOWN IMAGES. Note: I am not on the fastest broadband connection in the world, but I'm not on the slowest either.
I am not going to mention this particular web site, but on the main page they have a banner image that is displayed at 1038px x 146px, and its file size is 159kb. The actual image is 1920px x 240px. I copied it, scaled it to 1038px x 146px and the image size is now 38K, or about 4X smaller.
Same site, same front page, there is a 374px x 245px, black and white image, and its file size is 51kb. It is also scaled down, to 167px x 125px, and it also happens to be a B/W image (not greyscale) but its color depth is set to 24-bit. If you reduce the color depth to 1-bit, and save it as a .PNG file, the file size is now 1,498 bytes, or about 34X smaller.
One main feature of this particular website is to inform its readers about upcoming events. Do they use a graphical calendar? No. Do they have a paragraph in the middle with a date highlighted in red? No. What do they use? Would you believe MARQUEE text? MARQUEE text was cute in 1995, and it didn't last that long. It is so annoying and worst of all in this case, you have to wait about 45 seconds to read the entire paragraph of information, since it is scrolling by.. Good grief...
So I follow a link on this website and it takes me to another page that contains 54 images. The first one on the top is 798px x 598px, but I notice it is loading REAL slow... I check the properties of this image and of course, its real size is 3264px x 2448px and its file size is a whopping 3.02MB (A scaled down version saved is 145kb). It took 2 minutes and 12 seconds to download and display this page. Nobody is going to wait that long to see your 54 photos.
In summary...
- Do not use HTML to scale your images down
- If a photo is B/W, save it as such.
- Do not use MARQUEE text
- Do use PNG or JPG depending on the application
- Do test your webpage from various connections after you are done. Just because it loads fast on your Intranet doesn't mean it is good enough for the average Joe out there on a DSL connection.
One more thing... When I go to bookmark this page, its title is "HOME PAGE". Won't help you much when you are searching bookmarks later that month...

I just don't understand how you are going to select the Move option using your arrow keys if you can't see the menu. The solution of course is to press "M" on the keyboard after pressing ALT+Spacebar.

- SAVEAS saves the current drawing to a new file name. Example: If you are working in "A.DWG" and you run the SAVEAS command and specify "B.DWG", then "B.DWG" is created and is now the current drawing in the editor.
- QSAVE simply saves the current drawing. If the current drawing is unnamed (not yet saved) or it is read-only, then QSAVE behaves like the SAVEAS command and allows you to specify a file name and location.
- SAVE writes the contents of the editor to disk. It is like SAVEAS in that you get to specify the file name and location, but the currently loaded drawing remains unsaved and unchanged, even though DBMOD is reset to zero in the current drawing. Using the above example, if you are working in "A.DWG" and you run the SAVE command, and specify "B.DWG", then "B.DWG" is created from the contents of the editor, but "A.DWG" remains loaded, unchanged, and unsaved.
The exception to this rule is that when the SAVE command is executed in an unnamed drawing, it behaves like the SAVEAS command and names the current drawing.
To confuse things even more, the pull-down menu entry titled SAVE, actually executes the QSAVE command. The SAVE command is only available at the command prompt.

- You can use RibbonClose and Menubar to remove the ribbon and restore the normal pull-down menus.
- You can use the Menu command to load any menu you want, even though it won't help all that much since commands not on this list will not work.
- The Xref/Image/ExternalReference command (they all do the same thing) opens the palette which is missing the right-click commands, but if you use the -XREF and -IMAGE commands, you can actually attach a drawing or image.
- The Dsettings command is available.
- The ClassicLayer command is available.
Here is the complete list.

Ok, getting back to the last (ssget) call in part 1...
(ssget "_W"
(list 5.0 5.0)(list 8.0 8.0)
'((0 . "CIRCLE")(-4 . "<")(40 . 1.0))
)
The "_W" is the window selection method. Then we are passing it two points (5,5 and 8,8). Then we are telling it to only accept circle entities. The last two pieces tell it to only accept circles whose radius (DXF code 40) is less than 1.0.
So in summary, this bit of code will search the entire database and return only circles whose radius is less than 1.0 who also lie inside a polygon defined by the corners of 5,5 and 8,8.
The -4 group code is a special code that lets you perform relational testing. There are codes for equal, not equal, less than, less than or equal, greater than, greater than or equal, and two bitwise operators.
This type of filtering works great for locating entities on a certain layer, or that have a certain color or linetype.
(ssget "_X"
'((0 . "LINE")(8 . "TEMP"))
)
The code above will select all LINE entities on the TEMP layer.
(ssget "_X"
'((8 . "TEMP")(62 . 3))
)
The code above will select all entity types on the TEMP layer whose color is green (3). Be careful when filtering for color, linetype and lineweight. These filters only apply if the particular property is explicitly set. In the example above, if the color of all entities on the TEMP layer is set to BYLAYER, the selection set will be empty, even if the color of layer TEMP is green (3).
You can use wildcard matching in selection set filtering also.
(ssget "_X"
'((0 . "DIMENSION")(3 . "DIM##"))
)
The code above will select all dimensions whose dimstyle is DIM## (where the # represents a single numeral). For example, a dimension whose dimstyle is DIM55 or DIM39 will be selected. Dimensions with a dimstyle of DIM4T, DIM777, DIMKK, or DIM are not selected. Other wildcard syntax can be found under the (wcmatch) function in the Autolisp Reference Guide.
You may have figured it out by now, but "AND" is implied when when combining multiple filters such as above. In other words, in the above example, it's going to find entities that have the type dimension AND whose dimension style is DIM##. There may be cases were you want to specify "AND", especially if you are using an "OR" also.
(ssget "X"
'(
(-4 . "<OR")
(-4 . "<AND")
(0 . "CIRCLE")
(40 . 1.0)
(-4 . "AND<")
(-4 . "<AND")
(0 . "LINE")
(8 . "ABC")
(-4 . "AND<")
(-4 . "OR<")
)
)
The code above is straight out of the Autolisp Developer's Guide. It creates a selection set out of CIRCLE entities that have a radius of exactly 1.0 and LINE entities on the ABC layer. If you did not use the "OR" condition, then the (ssget) function would be trying to find entities that are a CIRCLE and a LINE, which is obviously impossible. Let's look at one more example.
(ssget '((0 . "POLYLINE,LWPOLYLINE")(-4 . "&")(70 . 1)))
Last, but not least... The code above uses a "bitwise AND" to filter on a bit coded DXF code. In this case, DXF code 70 on a POLYLINE and/or LWPOLYLINE. The goal here is to create a selection set of closed polylines. If DXF code 70 has the "1" bit set, this indicates a closed polyline. However, we cannot simply filter for DXF code 70 = 1, because this is a bit coded field. If LTGEN is turned on and it's a closed polyline, then DXF code 70 will equal 129, not 1. This is why you must use the "&" (Bitwise AND) special filter.
There is much more information in the Autolisp Developer's Guide on advanced selection set handling. Good luck and post some of your examples in the comments section if you want.

If you have written routines with Autolisp, then you have probably used the (ssget) function to select entities on the screen, either automatically or by prompting the user.
(ssget) is a powerful function that can do more than you probably realize. Let's look at a simple example.
(ssget '((0 . "TEXT")))
This prompts the user for a general selection set, but only TEXT entities are added to the resulting selection set.
(ssget '((0 . "*TEXT")))
Notice the wild card that was added. This is the same as above, except now any entity type that ends in TEXT is added to the selection set. At first, this looks like a good way to select TEXT and MTEXT, and it is. However, you have to be careful because this will also select RTEXT entities, and if your code is not equipped to deal with RTEXT, it may fail.
(ssget '((0 . "MTEXT,TEXT")))
This is a better way to select MTEXT and TEXT entities. But what if you don't want to bother the user to select entities, you just want to select ALL the MTEXT and TEXT entities in the drawing?
(ssget "_X" '((0 . "MTEXT,TEXT")))
Notice the "_X" that was added. This tells the (ssget) function to evaluate every entity in the drawing and then the filtering mechanism will filter out everything except MTEXT and TEXT. Entities on frozen layers are included when using the "_X" selection method.
Let's look at some other selection methods.
(ssget "_W" (list 5.0 5.0)(list 8.0 8.0))
Above is an example that will select objects inside a window from 5,5 to 8,8.
(ssget "_CP" (list (list 5.0 5.0)(list 8.0 8.0)(list 8.0 3.0)))
The line above will select all entities inside or touching a triangle defined by the points 5,5; 8,8; and 8,3. The CP is for crossing polygon.
The power of (ssget) comes from the incredibly fast filtering that it performs. Can you imagine having to evaluate an entire database of entities and manually filter out all the circles whose radius is less than 1.0 that fall inside a particular polygon? (ssget) can do this very fast. Example below.
(ssget "_W"
(list 5.0 5.0)(list 8.0 8.0)
'((0 . "CIRCLE")(-4 . "<")(40 . 1.0))
)
More details on this code and other examples in part 2.

(defun-q mystartup ()
(command "._purge" "_R" "*" "_N")
(command "._-scalelistedit" "_R" "_Y" "_E")
)
(setq S::STARTUP (append S::STARTUP mystartup))
Notice that we did not directly define (S::STARTUP). Because this function can be defined in other places, it is best to append to it rather than overwrite it. Use (defun-q) to create a function defined as a list, so it can be appended. To finish the example from the previous post...

If you have lisp routines that you want to make available in each drawing session, forget the "Startup Suite" and load them using the "acaddoc.lsp" file. "acaddoc.lsp" is not included with AutoCAD, you create it yourself. But it is nothing more than a plain lisp file, except that the first one found at drawing startup (just put it in your support file search path), is loaded automatically each time a drawing is opened.
Why use this approach instead of the "Startup Suite"? Ease of migration for one thing. When you upgrade from your current version of AutoCAD to the next version, simple add the path of your "acaddoc.lsp" file to the support file search path and your done. More details about this can be found here in a earlier article.
The second reason is that if you have more than one AutoCAD install to manage, using a networked copy of "acaddoc.lsp" means that you can control each machine using a single file as opposed to using the "Startup Suite" where your startup routines would have to be updated one machine at a time.
Remember that the file "acad.lsp" can contain startup code also, but "acad.lsp" is only loaded once per session of AutoCAD (assuming that the system variable ACADLSPASDOC is set to it's default value of zero). Each drawing has it's own lisp environment so it's necessary to load your startup lisp routines using "acaddoc.lsp" so that they will be loaded for each drawing.
Since "acaddoc.lsp" is like any other lisp file, it can contain functions and/or lisp code itself. Be careful when including lisp code because the (command) function should not be called until after AutoCAD initializes. You can do this safely by using the (s::startup) function. More on that next time.
Here is a sample "acaddoc.lsp" file.
;;; acaddoc.lsp
(load "mylisp")
(load "another_lisp")
(load "\\\\server\\share\\a_lisp_and_specify_the_path")
(setvar "blipmode" 0)
(setvar "highlight" 1)
;;; end acaddoc.lsp

Here is a simple example of how to read a TXT file into lisp and then do something with the contents. In this example, the TXT file contains coordinates, and the code will draw either points or lines.
One thing to keep in mind. Most times when you open a file for read or write, you should open the file, perform the entire operation, then close the file. Keep the code to a minimum while the file is open. This way if you run into an unhandled error, the file isn't stuck open, and in the case of shared files, you are not locking the file for an extended amount if time.
Here is a sample of the TXT file we are reading with the code. It contains X and Y values, separated by commas.
3121284.38296466,882181.92380207
3121277.99413417,882267.69275572

3121224.47339393,883240.46739907
Here is the code. Keep in mind that this code was left in a simple form to help show the steps involved. It is not optimized and there is no error checking and/or restoring of changed sysvars. These are topics for a different tutorial.
(defun c:foo ( / fn fp lst l)
;; Prompt the user to select a .TXT file.
(setq fn (getfiled "Select ASCII file" "" "txt" 4))
;; Prompt the user for what type of entity to draw
(initget "L P")
(setq e (getkword "\nWhat type of entity [Line/] "))
;; Open the file and create an empty list
(setq fp (open fn "r") lst '())
;; Iterate the file, writing each line to
;; the list

Starting with AutoCAD 2008, you now have direct access to the Layer States Manager, without opening the LAYER dialog first.
In AutoCAD 2008, click the button on the far right of the LAYERS toolbar.
In AutoCAD 2009, click the button shown below:
Once you get the Layer States Manager dialog open, don't forget to click the 
button to expand the dialog and reveal more options.

In certain situations, you can install SP2 for Land Desktop 2008, and the program will report that SP2 is installed, but in fact it is not really installed. I have confirmed this with Autodesk support. However, the exact circumstances regarding how this occurred has not been determined.
So how can you check to see if SP2 has really been applied? According to Autodesk support, you can test for SP2 by looking at the version of this file:
C:\Program Files\AutoCAD Civil 3D Land Desktop Companion
2008\AeccAlnSvrLoader.dll. (Your path may vary)
If you have SP2, this file version will be 17.1.396.0
This is for Land Desktop Companion 2008. I do not know if the same rules apply for plain Land Desktop, but I suspect it would be the same.

If you try to open a dialog in AutoCAD but nothing happens, there is a chance that the dialog is open, but it's just "off your screen". You can use a windows trick to move it back.
When the dialog is supposed to be visible, but you can't see it, press ALT+Space, then "M", then use the arrow keys to move the dialog.

I frequently see the question "What is the difference between AutoCAD and AutoCAD LT?" Autodesk provides a comparison matrix that highlights some of the differences. (That particular document compares the 2008 versions).
But there really doesn't seem to be a comprehensive comparison of what the actual differences are. I imagine many new LT users figure out a command is missing when they go to use a familiar command and it tells them...
Command: XCLIP
Unknown Command "XCLIP". Press F1 for HELP.
Below I have listed a quick summary of major differences, a quick summary of the new features in LT, and then a list of 323 commands and 175 system variables that are available in AutoCAD, but not available in AutoCAD LT 2009.
General list of what is missing in LT...
Here is a summary of the major features that are not included in LT 2009.
- Sheet Set Manager
- Network licensing
- CAD standards management
- Most 3D tools and commands
- Express tools
- Action recorder
- Support for Autolisp, VBA, .NET and other programming languages.
New for LT 2009...
Besides the normal UI upgrade to match AutoCAD, the following previously unavailable features have been added to LT 2009.
- Image referencing
- Non-rectangular viewports
- Truecolor
- Fields
- 64-bit support

So you have installed SP1 and you know how to fix drawings with a bloated scale list. But what if you have dozens or hundreds or thousands of "infected" drawings each containing hundreds of scale list entries?
Autodesk has released a tool to fix these bloated drawings. You can select any number of drawings and batch process them.
You have heard about this tool, haven't you? If not, that means you are not reading Shaan Hurley's Between the Lines blog. Here is the link to the Scale List Cleanup Utility. While you are there, I suggest subscribing to this blog to keep up to date with the latest happenings at Autodesk.

New to 2009 is the default icon mode for the drawing tool buttons. You know what these are, the SNAP GRID ORTHO POLAR OSNAP, etc. buttons down in the status bar. They take up less room as icons, but you will need to figure out what each one does.
Out of the box, they look like this:
If you right click on any button, you will get this menu:
Uncheck the Use Icons item to restore the previous TEXT buttons, like this:
Polar Tracking, Object Snap, and Object Tracking include a context menu to quickly change settings without having to open a dialog.
New to this bunch of tools is the QP, or Quick Properties button. Heidi Hewett has put together a nice article on Quick Properties.

How do you set system variables at drawing startup in AutoCAD? This can be answered in a variety of ways, some right and others wrong. I'm going to explain the right way based on Autodesk recommendations.
First off, what do you want to set and where is this setting stored? Look up the system variable in HELP and find out if it's stored in the drawing, or the registry or not at all.
If it's stored in the drawing, then consider whether or not you really want to change this at startup. While you are thinking about that, open you template drawing(s) and make the change there. Now at least your new drawings will be set the way you want.
Now why would you not want to change a drawing-saved system variable at startup? Have you ever opened a drawing, and not changed anything, then tried to close it and you were prompted to save? This is why. If you have startup code that changes a drawing saved system variable, the drawing database is modified and you will be prompted to save the drawing, even if you have not changed it in any other way.
NOTE: DBMOD is a system variable that is set to zero (0) each time a drawing is opened. If anything is changed, the value of DBMOD is not zero (0) any longer. When you go to close the drawing, if the value of DBMOD is not zero (0), then AutoCAD will prompt you to save.
Before we get started, let's cover a couple of "rules".
- Make sure ACADLSPASDOC is set to 0. This is the default setting.
- A file called "ACAD.LSP" is loaded once when AutoCAD starts. Any lisp code in this file is loaded into memory or executed at this time.
- A file called "ACADDOC.LSP" is loaded each time a drawing is loaded, including when AutoCAD is first started. Lisp code from this file is loaded each time a drawing is loaded.
- For either file above, AutoCAD will load the first file it finds and only the first one.
- AutoCAD will search the support file search path, in the order of the paths.
Things you might want to put in "acad.lsp" include system variables that are not saved or saved in the registry such as "expert", "isavebak", "and savetime"
Things you might want to put in "acaddoc.lsp" include drawing saved system variables (although I personally avoid this), and other lisp code that need to be defined in each drawing
Once you have determined which file to edit/create, here is how to do it.
- Open AutoCAD.
- Paste one of the following lisp functions (in blue) to the command line and press enter
- (findfile "acad.lsp") -or- (findfile "acaddoc.lsp")
- If a filename is returned, open this file in Notepad or use the VLIDE (Visual Lisp interactive development environment) to open this file. Go to step 5.
- If nil is returned, open a new file in Notepad or the VLIDE. Save the file using the correct name and make sure you save it to a directory that is in your support file search path. Close this file, and repeat step 2 and 3 to make sure AutoCAD can find this new file.
Now you have the right file open. You just need to add a bit of lisp code to set the variables to your liking, using the (setvar) function. Here is a few examples:
(setvar "EXPERT" 3)
(setvar "EDGEMODE" 1)
(setvar "OSMODE" 20)
The case of the letters is not important. But the value(s) that you are trying to set are important. In the first example, we are trying to set the system variable EXPERT to 3, which is valid. But if we try to set it to 8, it will fail.
Valid settings for each system variable are found in HELP.
Many system variables are stored as a bitcode using the sum of individual values. OSMODE is one of these. If you look in HELP, you will see that the setting for QUA object snap is 16 and the setting for NOD object snap is 4. If you add these two together, you get 20. If you wanted to set END and MID you would add 3 more and make the setting 23.
Remember, this is only addressing the changing of system variables. Next time, we'll cover adding more sophisticated lisp code to the startup files.
Note: Do not modify the files named "acad200?.lsp" or "acad200?doc.lsp". These files are located in the stock AutoCAD support directory, but these files are used by AutoCAD. If you place your startup code in these files it will work, but these files may be overwritten by a repair, reinstall, or application of a service pack. There is NO reason to use these files. Use "acad.lsp" and/or "acaddoc.lsp". These are user defined and controlled files.
