.3DA File Extension

3D Assembly

3D/CAD File
3DA files are three dimensional model files that are created from a text file. The file itself is human readable and may be opened in any text editor; each line in the file corresponds to the three dimensional locations that make up a single point on a vertice. The first and the last vertice in a simple object will often be the same; however, 3DA files may also be used to describe very complex objects made up of hundreds of simple 2D planes described by vertices.
