I am facing very slow performance when I open line drawings in PDF format exported from CAD Software.
Every operation (such as drag-select, deselect, group, ungroup, move, copy, paste etc) freezes the system for short or sometimes 5-15 sec or more!
Initially, I was thinking it could be because the drawings are complex and have too many curves - but then I noticed that it's happening even for simple drawings as well.
It works fine when very complex graphics developed naively in AD though.
Has anyone else noticed such an issue?
I have attached an example file with I am facing such slowdown issue.
I am running Designer 1.7.2.471 on Windows 10, 64bit, Intel i7 6700, 16GB ram, NVIDA 6GB GTX 970M Graphics.
