Offset a rectangle to separate lines.

Hi ALL,

You know how when you offset a rectangle it it stay as a polyline? i need a lisp routine that i can use to offset the rectangle, set the new lines to current layer, and substract the offset distance from both end of the line. i know thats asking alot but has anyone seen a routine like this?

Thanks,
Brian

Can't say that I have seen anything like that. What are some steps that may be needed to accomplish this? I would think:

• Get a record of the last entity in the drawing
• Request the user to select the rectangle to offset
• Copy said rectangle
• Change the layer of the copied rectangle
• Explode the copy of the rectangle
• Create a selection set based on the previous selection set (The explode command created a new selection set with all of the base entities from the previous rectangle).
• Determine the side of the rectangle to offset to
• Offset each item in the new selection set
• Delete said selection set

Of course, there may be other steps.

This sounds like it would be a really neat application of Lee's mad-crazy grvecs/grdraw skills.
