OpenVSP is a parametric geometry tool for conceptual design. The program is intended to be easy to use with intuitive graphical interfaces that do not need much documentation. Historically, OpenVSP had no in-program documentation.
There are certain areas where things get more complex and deep-dive documentation is warranted. These in-program help files will be added as needed, but this also presents an opportunity for users to contribute.
OpenVSP geometry is described via a set of parametric components. Each serves a particular purpose and can be added to a model as needed.
