I have a Lisp using the GRDRAW to show lines when the user moves the cursor. Every time the mouse moves, the lisp calls REDRAW to clean the old lines before drawing the lines for the new position. In Icad 7 this does not longer work, the lines drawn with GRDRAW remain on screen.
Any idea for a quick work-around, without changing too much of my code?

Hi,

Use (grclear) to clear the lines created by the GRDRAW function.

Great, thanks a lot. I discovered grdraw and grread recently, and just when I liked it I found this problem. Now I have grclear to solve my problem!

I searched a little more and found also grtext and grvecs. A pitty that there is no documention in the icad help.
