It does not gives error in 3D modeling, or havent encountered it yet their as I have just started using SW 2018 Premium. But when I start making drawing of a part it gives that error after sometime while I am working on my drawings. Sometimes it gives error after 1 or 2 minutes into the drawings and sometimes after 5 or 10 minutes, its quite random. One thing that I have noted that the error is occurring while I am dimensioning the views.
I have HP Probook 450 G3, ATI Radaen 360M GFX card having 2Gb memory.
Core i5 6th Generation processor and 8 Gb RAM.
