For January, Harry's picks include the following: Automatically Create New Layers for Xrefs — Bob Qualls — One way to put automation to work is by making it easy for you and your users to follow standards in AutoCAD, and that's just what this routine does. It allows you to attach an xref on a new, unique, locked layer and that layer will be locked.
Calculate Statistics for 3D Solids — Michael Weaver — This routine will calculate the volume and center of gravity for one or more 3D solids in AutoCAD.
Set Object Transparency — Samuel Lucido — Transparency is a great new feature in AutoCAD that is often overlooked. Sam's routine makes it easy to set transparency on a selection set — and to remove it later.
Draw Batt Insulation — Theodorus Winata — Frequent conributor Theodorus is back with a nice routine that draws batt insulation.
Zoom Extents Alternative — Jim Dee — If you have ever had a drawing in which you execute Zoom Extents and your drawing disappears, then this LISP routine might be for you.
Change Color of Current Layer — Matt Sibum — This routine is simple, but is can certainly save you some time in AutoCAD. It will change the color of the current layer in one quick step.
