Thanks very much. Very good explanation. I understood everything.

Here are excerpts from Photomodeler Lite Help:

"Export
PhotoModeler can export the following types of data from the project: 3D Points, Point IDs, 3D Lines, 3D Faces, Surface Draw, and Cylinders. Not all file formats can support all these types. The various export data types will enable or disable based on the Export Type selected and what that format can support. Note that in PhotoModeler Surface Elements are equivalent to 3D Faces in the export.

Export Type
The Export Type drop down list specifies which type file format to export. Currently supported types in Lite are: Autodesk 3D DXF, VRML 2.0 and Autodesk 3D Studio (3DS).

Any suggestion on what to use then?

Thanks.
