I have one problem with solidworks 2013... little hard to explaing but i hope You will understand me. When I create couple features, and click with my mouse cursor on some feature in feature desig tree, on my part sketch starting to show up but not in once. It starting to show up like some kind of slide show. Every singl line is starting to filling up her place and it took time( 5-6 seconds) and it's pretty anoying, and also my computer freeze until it's over. I hope my explainations is understandable. Does anyone have some idea to solve this?
