I often import dxfs of board shapes into EasyPC and I frequently get the error "Cannot import 'splines' - imported data may be incomplete".

Would it be possible to make EasyPC able to import splines from dxf?

Thanks!

Thanks Iain, I'll do that. :D

I have had this problem also... however if you ask whoever supplys you the DXF file of the problem, apparently is is fairly easy for them to re-generate the file using polylines only. This will then imprt no problem.

Unfortunately, this is essentially almost impossible. The reason is that splines are, by their very nature, compound curves. That is, a curve, where the radius of curvature is dependent on the position on the curve (such as you'd get with an ellipse).

Easy-PC only has provision for using straight lines and circular arcs, and has no structure capable of accepting a compound curve. The only way that spline import could be implemented would be the messy one of piecewise approximation with small segments. In theory this is possible, but it would be slow, and difficult to edit.
