Draw Lamé Curves — Kent Cooper — This routine creates Lamé curves in AutoCAD, otherwise known as superellipses. Thanks for introducing most of us to superellipes, Kent!
Multiple Fillet Radius Values — Kent Cooper — In the spirit of similar tips, this routine lets you save and reuse multiple fillet radius values with the F0 through F9 commands in AutoCAD. This routine handles as many as 10 remembered radius values, but more commands can easily be added if needed, including the possibility of letters instead of numbers (e.g., FA, FB, etc.), as long as care is taken not to conflict with command aliases.
Fillet Match Radius — Kent Cooper — This routine allows you to select an existing curve to set the radius for an immediate fillet. This is similar to Tip #1468 except that Kent's version here also handles polyline arc segments in addition to arcs and circles to set the desired radius in AutoCAD.
Fix for Fillet "Radius is Too Large" — Kent Cooper — This routine will report the maximum radius that will work in a given fillet situation as well as the current radius value assigned to the AutoCAD Fillet command.
