OpenVSP

OpenVSP (also Open Vehicle Sketch Pad) — is an open-source parametric aircraft geometry tool originally developed by NASA.

Predecessors to OpenVSP including VSP[1] and Rapid Aircraft Modeler (RAM) were developed by J.R. Gloudemans and others[2] for NASA beginning in the early 1990s.

OpenVSP allows the user to quickly generate computer models from ideas, which can then be analyzed.

Geometry created in OpenVSP may be exported as STL, CART3D (.tri), PLOT3D, STEP and IGES, OBJ, SVG, DXF and X3D file formats.

[8] All of the v3 models on the Hangar have been ported over to the Airshow.OpenVSP Workshop — is an offline event where developers and users meet to discuss progress and use of OpenVSP.

[10] OpenVSP Ground School is a set of comprehensive tutorials under development by Brandon Litherland at NASA.
