Set Scale List Defaults Quickly — Michael Partenheimer — This tip offers a fast way to reset the scale list defaults in AutoCAD. Note that this LISP routine does not set the scales in a particular drawing, but rather sets up the defaults that you see when you go to Options > User Preferences > Default Scale List.
Multiple Shortcuts for Saved Chamfer Distance Values — Kent Cooper — Building on a similar tip, Multiple Fillet Radius Values, this similar routine works with the Chamfer command instead of Fillet. The commands C0, C1, C2, etc., can be defined for quick access to saved chamfer values.
Find Point at a Distance along an Entity — Kent Cooper — This routine will help you place something, or otherwise calculate a point, at a specified distance along an arc, a polyline that bends, a spline, or partial ellipse.
Easily Rename Blocks — Kent Cooper — This entry improves on his previous block renaming routine. This updated version allows the user to select the block before executing the command, and then you are prompted to rename the block in a dialog box rather than at the Command line.
