OpenVSP - Parametric Geometry

[h=1]OpenVSP[/h] NASA Open Source Parametric Geometry

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 J.R. Gloudemans and others for NASA since the early 1990's. On January 10 2012, OpenVSP was released as an open source project under the NASA Open Source Agreement (NOSA) version 1.3.

We are still in the process of setting up all of the things which allow an open source project to work. In the meantime, get OpenVSP for yourself from the links below.
