VScad3 File Menu

2.1.4 Import.

"File / Import => DXF..." : This will import a ".dxf" file. Only the following basic DXF geometry types are imported: Point, Polyline, Polygon, Text. Other entity types in the imported file (if present) are ignored. The newly-imported entities are merged into the current model. To be certain that all imported entities are within the field of view, select the "Workspace / Region..." menu and click on "Auto Adjust" (and then "Apply").

"File / Import => Triangles..." : Use this menu to import a "triangle" (".stl") file as a polygon mesh. After the file is selected, the "Select STL File Type" dialog will appear. This dialog has two fields. The "Select STL input file type" setting specifies if the selected input file is in Binary or ASCII format. Most ".stl" files are Binary format due to the compact size compared to the ASCII format. The "Vertex Merge" setting can be "Yes" or "No". If "Yes", then duplicate vertices are merged. Merging the vertices can take a considerable amount of time, depending upon the number of triangles and the amount of memory available on the host system. But once loaded, the polygon mesh is more efficient (slightly faster display time) if the vertices have been merged. The ".stl" files usually have a large number of duplicate vertices. If the vertices are not merged, then the polygon mesh "Shading" attribute ("Flat" or "Gouraud") will have no effect because the appearance will always be like the "Flat" setting.
