Carl,
X3 works the same as it always has when rounding the corners to a scaled rectangle. Gary's test shows only that it kept the same % roundness (but of the original rectangle).
The "fix" is to use X3's Fillet/Scallop/Chamfer docker. It allows absolute values (instead of %) and prompts user to allow it to "undistort" the object.
Your macro, then, will be useful to X3 users also if they are used to putting in percentage radius rather than absolute value (the docker's only option). Also, the docker applies the absolute to *all* "corners" whereas using your macro and the "old" method allows us to radius whichever corners we need and even different corners to different radius.
This post makes it sound like the new Fillet/Scallop/Chamfer docker is not that useful, but not so; I consider it worth the price for the upgrade. e.g., we can now fillet *any* shape, not just a rectangle! Roy Brewer
