Introduction
Any cross-section type in OpenVSP may be converted to an Edit Curve by clicking the “Convert CEDIT” button next to Show and the type dropdown menu in the XSec tab (for bodies). Some cross-section types may be exactly recreated by the conversion process such as ellipses and rounded rectangles while other, more complex or mathematically strict, types may be approximated. Users should be aware of the limitations when converting different section types for modification. However, in most cases a close match to the desired shape may be achieved with a stock cross-section and then converted to an Edit Curve for further refinement without much effort making this capability exceptionally useful to the designer.
