Could I get a step-by-step please? I can't reproduce the flat spot or the Coin error. This is what I'm doing:triplus wrote:I tested both versions of the macro on Ubuntu 13.10 using latest Development Release and can confirm that flat spot. It looks OK as Wire and converting to sketch gives predictable results. Converting to BSpline adds that flat spot.
1) Macro v2.0 from [wiki]Macro_Airfoil_Import_&_Scale[/wiki]
2) input file: NACA0007.dat, options: DWire, chord=100
3) run Draft DWire to BSpline tool on result
My results: And for NACA0012.dat: I must be doing something wrong (right?).
