File Formats
Unfortunately the tessellated mesh representation is common in many 3D file
formats, and is largely useless for defining enclosure shells. The DXF format
only allows for 3 or 4 sided objects. All representations are by mesh. This
means that only shells with faces of 3 or 4 sides may be imported using this
format. The same is true of the 3DS format, which appears to support only
triangular meshes. This is only useful for shells with triangular faces.
The OBJ format (Maya
)is by far the most suitable for this application. This format
provides full support for multisided polygons. Furthermore, by its structure
it also ensures that all vertex are identical for adjacent faces. The OBJ format
can be considered the native import/export format for this application.
