https://community.graphisoft.com/t5/Installation-update/AC-11-and-Mactel-bug/m-p/111597#M13376 We've had that problem sporadically since Archicad 9 I think... usually the solution is to quit Archicad and reopen it.

After using the software for a few minutes the stretch lines vanish when I zoom in . I also loose the stretch line when using any tool. When drawing a line, for example all you see is the cursor, no start point, no stretch, no indication that you are doing any action at all, but when you click the line materializes.<BR /> <BR /> Has anyone experienced this. The file works on PC.<BR /> <BR /> Any input would be helpful.</T></DIV> Thu, 02 Aug 2007 17:56:40 GMT https://community.graphisoft.com/t5/Installation-update/AC-11-and-Mactel-bug/m-p/111596#M13375 Anonymous 2007-08-02T17:56:40Z https://community.graphisoft.com/t5/Installation-update/AC-11-and-Mactel-bug/m-p/111597#M13376 We've had that problem sporadically since Archicad 9 I think... usually the solution is to quit Archicad and reopen it.
