I am a student doing a project for a company and have been asked to re-draw a shape in SolidWorks just using poly lines and export it as a .dxf I am slightly un clear how to draw something as just poly lines, do they differ from the basic lines in the sketch mode and if so where is the tool for them. Also can they have a rounded edge like a spline or must they be straight at all times.
Any help that you can give will be much appreciated.
A poly line is a continuous line having one or more line entities with their end points connected (no corner radius). SW don't have the tool to create this kind of line. But you can convert a collection of line entities into a PLINE using FIT spline option, though this will add small radii on the corners.
