IMPORTING DXF OF AIRFOIL SHAPE

dan_cumminsdan_cummins Member Posts: 4
I am trying to import the top half of an airfoil profile into a Parts Studio sketch.  I save the top of the airfoil as a polyline and/or a spline in another CAD program as a DXF or DWG.

When I go to import the DXF into ONSHAPE, and import it into a sketch, it imports as a series of line segments not a single entity......ie I cannot just make the one end coincident with a point or another vertex....if I do that, only the point I selected becomes coincident, and the rest of the points stay exactly where they landed when I imported the dxf.  So what I am really asking, is how do I treat the imported DXF as an single entity (like a poly line) that can be constrained?

I could trace a spline over the imported points, and delete the original import, but that seems its more complicated than it needs to be.

This seems like it should be simple, but I am stuck.

Your thoughts?

    Hi @dan_cummins - Onshape does not have a polyline sketch entity so will always treat an imported polyline as lines with no constraints. Did you try creating your profile as a spline and then exporting as a spline to DXF?
