Q - question

ATrim - dynamic trim/extend by painting.

A - answer With the free LISP utility ATrim you can easily trim or extend line geometry in AutoCAD drawings by "painting" with your mouse cursor ("PowerTrim").

Just download the ATRIM utility from, load it into your AutoCAD session with APPLOAD and type the ATRIM command. Now hold the left mouse button and "draw" (drag) over the lines you want to remove (trim), or press and hold also the Shift key with the left mouse button while dragging over the lines and objects you want to extend.

Use the +/- keys to resize the pickbox - a larger pickbox ("paintbrush") may be needed on slower computers. You may need Express Tools installed for ATrim. See also the PaintSelect utility.
