Contour Export

[Rudbeckia]

Hello

How do I export contours out of sketchup as a PDF or CAD file and have the contour lines be
continuous lines. The are exporting out as 1000s of tiny segments

thanks for any help

I should mention I have tried simplify contours, it crashes

Try welding the lines.
Curvizard will let you batch weld them.
