Q: I used the CAD recovery function but the drawing hasn't gotten any better!
A: CAD recovery is a semi-automatic function, which means that every action has to be confirmed.
A full recovery very often includes three steps: 1) check for problems, 2) audit/fix problems and 3) perform drawing adjustments.
Q: When I click the "open drawing" in the CAD window I immediately get an error message.
A: This is a known error in OptiWin 3D pro version 2010.3. Upgrade to the latest version to fix this problem.Q: I received a very large and detailed 3D drawing but is unable to open it due to lack of system resources.
A: To conserve as much resources as possible when opening a 3D drawing try to lower the quality slider before opening the drawing.
It might also help to switch to surface rendering, because wireframe rendering is often slower on regular computer hardware.
