Matching Names in Purge

I discovered recently that it is possible to use regular expressions in the purge command. If that doesn’t excite you, I don’t know what will.

A regular expression is a way to define a pattern. The pattern can be used to include or exclude the name(s) of a layer, linetype, registered application, or anything that can be purged.

Publish troubles?

Is the output of your Publishing endeavors not what you expected? Are multiple sheets being printed to a single PDF file, when you really want multiple files? Try setting PUBLISHCOLLATE to 0. If it is set to 1, AutoCAD will process the entire set of drawings being published as a single job.

I actually had a lot of problems when PUBLISHCOLLATE was set to 1 when I was using AutoCAD 2009, where the last sheet output would overwrite each previous sheet. This behavior seems to have been fixed in 2010, though.

Editing Hatches in 2010

I’ve been using AutoCAD 2010 for a few months now, and I’ve found some value in a few of the new features.  One that a colleague pointed out to me is the new grip editing features for hatches.  You may have noticed that when you click on a non-associative hatch, you’ll see grips appear.

It’s a handy way to quickly change those hatches without having to redraw the boundaries.

If you are into things that are cool

…then you might like this.  For those of you who don’t have Google Earth Pro, I found an application that will automatically download and stitch together Google map tiles (as well as Microsoft maps).  This means you can create a high resolution image of your map area, limited only by the maximum zoom level of Google Maps.

Here’s what you need:

Command Line slowness

Summer’s over!  I’m back from my vacations and forays into the world of pavement inspection.  Time to do some blogging.

I noticed that AutoCAD was ignoring certain keypresses occasionally.  For instance, when I was in the middle of a pline command, I’d type “cen” but “cn” would appear in the command line.  So I did a little googlin’ and came across this thread.  I wasn’t quite satisfied with the answer (what’s the point of dual monitors if I can’t display the non-modal windows on my second monitor?), so I played around a little bit and I think I found a solution.

In AutoCAD 2009 and onward, there are two command line windows, one that you access with F2, and one that you can access by typing “commandline” or hitting CTRL+9.  I prefer the F2 one because it is quicker to toggle on and off.  So I put the F2 command line window on my secondary monitor, and I noticed that I had tried to put the CTRL+9 command line window there as well, then turned it off.  Well, apparently AutoCAD still thinks it is there, because when I turned it back on and then docked it, the keypress delay disappeared.  Problem solved!  Now, with the CTRL+9 command line docked, I can turn it off, and the delay is still gone.

I tested this in Civil 3D 2009; I’m not sure if it will work in other versions.  Please let me know if it does or doesn’t solve your problem.

Civil 3D Data Shortcuts

The latest issue of AUGI World has a great article by Donnie Gladfelter about Civil 3D Data Shortcuts.  There is also some really useful info at the end of the article about saving memory and regen time.  Highly recommended for Civil 3D users.

Layout Selector

QVLAYOUT is a handy command,for sure.  It lets us hide our layout and model space tabs, recovering valuable screen real estate, and it provides a nice thumbnail view of each layout.  But it takes a few extra milliseconds to generate the thumbnails, and if you know you want to go to the first layout (which is often the case) and you are a keyboard commando, you might find this LISP routine useful.  It’s called LayoutNav.  Props to Lee Ambrosius for writing this back in 2003.

Load it up with APPLOAD, then you can use the command “FirstLayout” to jump right to the first layout tab.  I used ALIASEDIT to alias “L1″ to “FirstLayout”, so it’s EVEN QUICKER.  I’m into efficiency, if you haven’t noticed.

PDFCreator

PDFCreator is a free, open source printer driver that allows you create PDF files without the need for any Adobe software.  I use it all the time, using Acrobat only to crop and rotate my PDFs.  It features auto-naming and auto-saving, so it is great for batch plotting.  Check it out.

Introducing: the AutoCAD coordinizer

Happy New Year!  I’m back, and I have present for you.

I’m proud to reveal my latest bit of coding handiwork, the AutoCAD Coordinizer.  I originally created this in PHP, but didn’t have a free web host for it, so I just ported it to Python and put it on Google’s Apps site.

What it does, basically, is take the output of a LIST or ID command (or series of commands) and extract the X and Y values, placing them in a handy list.  I wrote it to simplify the creation of coordinate tables.
