If we publish your tip, we'll send you a "Cadalyst: CAD the Way You Want It" T-shirt, and each month Cadalyst editors will randomly select one published tip and send a $100 gift card to its author. Please submit only code and other tips that are your original work (or provide the original source so we can include proper credit) and tell us which software version you use. By submitting code, you grant Cadalyst the right to print and distribute your code in print, digitally and by other means. Cadalyst and individual authors retain all rights to the code; published code is not to be used for commercial purposes.

Editor's note: Cadalyst bids farewell to Tip Patrol member Ben Young, who is heading to a job overseas. We thank Ben for nearly a year of excellent volunteer work on our Patrol and wish him all the best in his new position.

We are pleased to welcome frequent tipster Brian Benton as our newest Tip Patrol member. Brian joins our illustrious panel with much experience. A CAD technician for 14 years and the senior CAD technician for his office at Heidt & Associates. Brian not only assists users but led the team who wrote the company's CAD manual. Needless to say, we are very excited to have Brian join our Patrol.

We'd also like to take this opportunity to thank all our Tip Patrol members for their time and effort. They are a great group of volunteers who work hard to ensure that the tips published in Tips & Tools Weekly are viable and useful.

Keyboard Commands
New Tip Patrol member Brian Benton offers information on easy-to-remember keyboard commands: AutoCAD users can interface with the software in many ways, such as via the mouse, toolbars, tool palettes, the Dashboard and the keyboard. He says all these can be customized to some degree but that many users aren't aware of the keyboard commands. "There are different types of keyboard commands: command aliases, function keys, shortcut keys, temporary override keys and Windows-based shortcuts.

"With the exception of the Windows-based Shortcuts, you can edit these keyboard commands through the CUI [Custom User Interface]. Click on Tools / Workspaces / Customize to bring up the CUI palette. Next, choose to edit all Custom Workspaces, or change an individual workspace and then select the workspace you wish to edit.
Shortcut keys come with default settings, but you can change and add whatever you need. Here are a few to get started." For Brian's full list, click here:

Redo Ctrl+Y
Undo Ctrl+Z
Clean Screen Ctrl+0
Properties Ctrl+1

NOTES FROM CADALYST TIP PATROL: Our Patrollers agree that these are great shortcuts. One Patroller adds, "This list shows how predefined keyboard shortcuts have evolved over the years. Although the emphasis [in AutoCAD] these days is on the graphic user interface and having a heads-up view, I personally still believe the most efficient way to draft is to fully use the keyboard and its myriad shortcuts. The only issue is to how to remember all these hotkeys. Once you couple the built-in keystrokes with your own personal ones for simulating AutoCAD commands, you may need a Britannica-like memory. Too bad we can’t just install more RAM into our heads."

Get Model Space Measurement
Reader Alan Harmon figured out a way to measure when in paper space. Alan explains: "I noticed, while in paper space, that when I measured the distance between two lines, it gave me the actual distance between the lines and not the 1:1 scaled dimension. For example, I had a drawing open in the Layout view in paper space. The viewport was set to 1/4" scale. As I was attaching some elevation ticks to an elevation, I took a measurement from the finish floor to the roof line. I knew I was in paper space, so I needed to convert the 1/4" dimension in my head to get the real distance. When I saw the measurement, I thought, 'Oh no, I'm putting this tick in model space,' but then I realized I was in paper space and it was telling me what the model space dimension was.
I decided to test this. Next, I checked the distance between my object in paper space against my object in model space and it gave me the true dimension between them at 1:1 scale. But, if I start the measurement from the model space object (while in paper space) to the tick, it gives it to me at 1/4":1'-0". This was a very interesting find. I wonder how long it has been available? I know it will help me from now on."

NOTES FROM CADALYST TIP PATROL: Our Patrollers believe that the Tipster is using dimensions and not distance for this tip. One Patroller explains, "With the system variable Dimassoc set to 2, you can insert dimensions in paper space while snapping to model space objects in a viewport, and the default dimension adopts the viewport scale while calculating the dimension. With Dimassoc set to 1, this associativity is turned off and the default dimension displays in true paper units. This runs a little deeper in that when dimensions are associated in this way, stretching or moving the object in model space updates the paper space dimension dynamically."

In addition, another Patroller shares an interesting tidbit about dimensions in paper space: If you go into FloatingModelspace and move the model, the dimension jumps to the new position when you go back to paper space.

Follow-Up: Toggle Tilemode with F4
Regarding our toggle discussion that began in the April 9 edition and continued April 16, Mark Matherne adds that "AutoCAD's way seems the easiest way to toggle between model and paper space. Use the Options command and in the Options dialog box, select the Display tab. Under the Layout Elements heading, check the box for Display Layout & Model Tabs. The tabs for model space and all layout spaces (paper spaces) are now visible along the bottom of your drawing. This is just like Excel and other programs work."

The original tipster in the April 9 edition, Kevin Pohlgeers, concedes that Brian Benton's suggestion in the April 16 edition of using the Tabs is an option, but remarks that using tabs is "not really a method of switching between paper and model space. It's just for switching up and down a list of tabs. The F4 button can take you to model space and then back to the same tab you left."

Tip Patroller Mitchell Hirschklau also agrees with Brian Benton's assertions in the April 16 edition with one exception. He explains, "Without any CUI customizations or programming, there are already default AutoCAD keyboard toggles for a variety of commands and settings. Users should not look for LISP or other customizations to do occasional actions that they can do by default. In this regard, Ctrl + PageUp is an excellent example." However, he adds that streamlining frequent and regular uses with some customization benefits the user (and his or her employer) enormously. "Personally, I've always been a keyboard jockey. Here are a couple of my keyboard customizations:

  • F10 toggles Tilemode. True, but my way takes only a single keystroke with one finger.
  • NUMPAD-8 toggles Properties. With a single keystroke and one finger, I can turn it on and off."

All this discussion has Richard Gill thinking. He shares, "This sort of thing makes me wonder how many times a new LISP routine is created for a routine or function that is already an inherent part of the software. Has it gotten so complicated to learn the functionality of our software by reading the user manuals or Help file that it's just easier to program a line of code? I love the fact that these folks can program circles around those that put out the software in the first place. But, it still comes down to the fact that these new lines of code are not truly tips."

Editor's note: We love LISP, and so do Cadalyst readers -- but Gill has a great point. This is a timely reminder that Tips & Tools Weekly is always on the lookout for non-LISP shortcuts and workarounds for AutoCAD and all other CAD software. Send us your favorite tip today. If we publish it, you'll be in the running for our monthly $100 prize!

Follow-Up: Paths to Drawings
In regard to the plot stamp discussion that originated in the March 26 edition, Rodney Lee agrees with using Rtext from the Express Tools menu, but he adds the xref files listed so he knows what files were used to create a sheet. He explains: I have the xref list on the lower left and other on the lower right corners. The saved line and the file line are in the lower right and list the time of the last save, file name and also when it was plotted.

SAVED$(edtime,$(getvar,tdupdate), MO/DD/YYYY - HH:MM am/pm )

XREF: $(xrefs,13,,; ) SAVED BY:$(getprop, LastsavedBy)

FILE:$(getvar, "dwgname") PLOTTED:$(edtime, 0, M"/"D"/"YYYY  H:MMam/pm)

MicroStation Tip: Changing Text Style Names in DGNLIBs
There’s an easy way to keep the text styles associated in a file but with different text style names. You can achieve this by using the standards checker and the batch process tool. Follow these steps:

  • Change the name of the style in your DGNLIB.
  • Set up the standards checker to check files against this DGNLIB.
  • Set up a batch processor with the command as "standardschecker execute" and all the files that you want to process added to the file list.
  • Run the batch program to process all the files in the list.
  • You are prompted to change the names of the styles that do not conform to the standard.

You've now changed the original elements that used the now-renamed style, so you must change those original elements or they won't conform to the standard. If you have renamed multiple styles, you have to map these individually.

Axiom offers many MicroStation Tips on its Web site.
