Anyone know what I am doing wrong? When I draw a part in SolidWorks then make a drawing of the model then export it to a DWG the arcs are no longer arcs they are splines. I also have a similar problem in SolidWorks as when I draw a sketche (as a radius) then do a sweep or anything else it changes to a spline so it can not even be dimensioned in solid works is this common? It is giving me all kinds of headaches in the manufacturing end. Thanks in advance to anyone that can help.
