I've two question
1) I'm working on a dwg file with shp file connections, on which I've made several style customizations, but now when I try to open again this dwg file I get the following error (see the first image) and I can't work on file. Someone may explain me how can I solve the problem?
2) on the same dwg file, I customize the screen of the shp with an ANSI 31 model and I would like to modify the thickness but I can't (see the second image). Is there a way to modify that?
thanks all can help me, and sorry for my orrible english
