AutoCAD 2012 – How to “hatch” using any objects

Here’s a trick you can use in AutoCAD 2012 to fill an area with any objects you like. It’s not actually hatching, but it has several advantages over the real thing:

  • You aren’t restricted to straight line segments as you are with real hatching. Circles, splines, even solid objects, you name it, you can use it.
  • To define the pattern, you don’t have to master an arcane file format or use trigonometry to work out the numbers used in it. Just draw the objects you want repeated.
  • You can easily change the spacing between the objects later, or even change the objects themselves.

How is this done? Use the new associative array feature, then use XClip to restrict the displayed objects to within a specified boundary. For example, let’s say you have a polyline you want filled with green spheres, and a green sphere already drawn. The sequence … Full post

How to make Ctrl+C perform a Cancel

In a recent comment, I was asked how to make Ctrl+C perform a Cancel. Before I get onto that, here’s a bit of history.

Back in the Dark Ages of DOS, the way to cancel a command was by holding down Ctrl and pressing C. The last release to work like this by default was Release 13 for DOS, released in 1994. I remember the bother it caused my users who were faced with the Windows version in which Esc was used to cancel things and Ctrl+C copied objects to the clipboard. It took me at least a year before I had totally removed Ctrl+C = Cancel from my muscle memory.

Until AutoCAD 2005, Autodesk provided an easy option to keep things the way they were by turning off the toggle Options > User Preferences > Windows standard accelerator keys. In recent AutoCAD releases, you have still been able … Full post

Installation tip – save time and space

If you download AutoCAD or other Autodesk products from either the trial or Subscription sites, the executable you get (e.g. AutoCAD_2012_English_Win_32bit.exe) is actually a self-extracting archive rather than a real installer. When you run it, you are prompted for a destination folder, with a default location such as this:


The actual installer (setup.exe) and all of the files it needs are then unzipped and placed in a folder structure in that location. When the extraction is finished, the self-extracting executable automatically runs setup.exe and the installation proper can begin. Once the installation is complete, the extracted files are left in place.

You can take advantage of this simple knowledge in various ways:

  • Sometimes, you may you need to run the installer more than once on the same PC. For example, you might need to uninstall/reinstall AutoCAD, or you might be a CAD Manager who installs AutoCAD for on your … Full post
