I'm not sure if this is the right forum to post into, but came across this tonight and thought others might find it intersting when designing something other than 3FNC.

OpenVSP is a parametric aircraft geometry tool. OpenVSP allows the user to create a 3D model of an aircraft defined by common engineering parameters. This model can be processed into formats suitable for engineering analysis.

The predecessors to OpenVSP have been developed by JR Gloudemans and others for NASA since the early 1990's. In January 2012, OpenVSP was released as an open source project under the NOSA 1.3 license.

VSP's direction and development was guided by some of the conceptual design groups in NASA. Those groups use VSP extensively. As VSP has gained more engineering capability, more groups inside and outside NASA have begun adopting it for their needs.
