If I try to draw a circle, or more than a single line with construction mode turned on, the entire program starts to have severe hitching, even on other projects/designs, as long as the offending sketch is open. Also, the construction lines in question will be invisible, with only the centerpoint/endpoint showing. Finishing the sketch does not resolve the issue, only deleting the construction line does. Drawing a regular line and then converting it to construction causes the same issue.&nbsp;</P><P>&nbsp;</P><P>I'm running Windows 8.1 with 8gb of ram, I5-4690k, and a Nvidia 1060 6gb.&nbsp;</P><P>Any help would be appreciated, as I am severely limited in what I can do without construction lines.</P> Fri, 26 Mar 2021 18:56:56 GMT https://forums.autodesk.com/t5/fusion-support-forum/construction-lines-causing-hitching/m-p/10190266#M87042 Anonymous 2021-03-26T18:56:56Z https://forums.autodesk.com/t5/fusion-support-forum/construction-lines-causing-hitching/m-p/10190276#M87043 <P>I had some graphics problems after the March update and found switching to the OpenGL graphics driver fixed the problem.</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="HughesTooling_0-1615454620311.png" style="width: 999px;"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/891660iD5A96FF5B325DE8D/image-size/large?v=v2&amp;px=999" role="button" title="HughesTooling_0-1615454620311.png" alt="HughesTooling_0-1615454620311.png" /></span></P> <P>Mark</P> Fri, 26 Mar 2021 19:04:09 GMT https://forums.autodesk.com/t5/fusion-support-forum/construction-lines-causing-hitching/m-p/10190276#M87043 HughesTooling 2021-03-26T19:04:09Z https://forums.autodesk.com/t5/fusion-support-forum/construction-lines-causing-hitching/m-p/10190282#M87044 That absolutely solved it, thanks!
