Hello,
Dimensions and comunication design tools are far more important - in my opinion concerning the impact it could have on my workflow - than line weights / line styles, overkill export options and rendered background image.
Have ViaCAD and i open it once or twice.
Naturaly other workflows have other needs and prioritys.
Hoping for 2D comunication tools in Moi3D 'style': Simple and efective.
Cheers
Carlos
