    Hello Bruce,

    Navigate here: https://bobcadsupport.com/technical-support/faq/

    Expand the question that says, “How can I improve the performance of BobCAD on my computer?”

    Run through the steps there and try using BobCAD again.

    Typically, with BobCAD crashing issues, those steps will solve 90% of all performance issues in the software.

    You will also want to make sure your computer is powerful enough to use the software effectively as well. Go here to check system requirements: https://bobcad.com/support-2/system-requirements/

    Typically, the most important thing is to make sure that BobCAD is linked with your graphics card (see steps to link in the FAQ page).

    If you have tried everything above and are still running into issues with the software, please give us a call at (727) 489 – 0003 or email at [email protected] and we can take a further look at your computer for you.

    I hope this helps!
