In the attached file you can find a part for which editing of sketches is almost impossible.
When you rotate model dimension values float above the plane, and when you do not rotate some dimension values and dimension lines are hidden under the surface of model.
The part was created with 2015 version. I tried opennig the file in newer version of SolidWorks 2016 and problem still exists. It happens with NVidia GPU and AMD Radeon GPU. Solution posted here: Stop dimension values from floating above sketch - doesn't fix it.
Do you know how to get rid of this strange behaviour. The model is quite simple so I can recreate it from scratch but I don't want it to happen when I will work with much more advanced part.
