MacPerspective translator

This MacPerspective Translator utility takes a native MacPerspective model file and converts the geometric information into a file format suitable for exporting to other 3D modelling packages.

Note: to transfer views of a model into a 2D package use the Copy to Clipboard option inside MacPerspective. This is particularly useful for transfering a 2D view of the model into ClarisCAD for plotting.

Operation

The basic way of translating a model is to open a MacPerspective file and then "export" to the format of your choice. After opening a model you can use this program to view it from various angles, this is useful for model checking purposes. The export formats are selected under the option menu.

This program is continually being "touched up", and thus it is not appropriate to comment on the exact contents of the options menu, explore for yourself.

During the translation various parameters as well as the progress status are displayed. Of particular interest are the number of duplicate edges removed and the number of each type of geometric element saved which is displayed at the end of the exporting process. The number of 3 and 4 point facets are shown as well as the number of lone edges. Lone edges are the number of edges which did not form part of a facet and give an indication of how complete the specification of planes has been.
