Run SW RX and send the file to VAR
We had some new systems using Intel IGP that also would crash upon basic use of sketch but were otherwise fine. This was 2018 SP1.
Upgrading to SP 3 seems to have fixed the problem.
I might have double posted:
after speaking with the var I was able to find the problem. I had to add solidworks.exe into my Nvidea control panel. I am using an Nvidea 1070 and after the last batch of updates from Windows (10) and nvidea (running a GTX1070) solidworks sketchea began to crash ( and only while sketching, I could view solids and manipulate assemblies just not sketch). The var recommended reinstalation of solidworks and my graphics driver however that did not work. The next recommendation was to add the solidworks.exe file to my Nvidea control panel and that was the trick.
