 In order to generate nice visualizations and animations, CAD geometry can be added to Spavisual. At this page, an example is provided how CAD geometry can be added to the visualization by exploiting the USERPLOT function of spavisual. In order to generate nice visualizations and animations, CAD geometry can be added to Spavisual.

-First of all, the CAD geometry has to be saved in an .STL file. When saving the .STL file, it is important to save as ASCII with units in meters. In Solidworks, these settings can be set via 'save as => select .stl => options'. Furthermore, make sure you check the 'Do not translate STL output data to positive space' checkbox. Optionally, you can also provide an alternative coordinate system while save the .STL file. In the visualization, the origin of the selected coordinate system is going to coincide with a spacar node.  +First of all, the CAD geometry has to be saved in an .STL file.

-For adding the .STL geometry to Spavisual in Spacarlight, the ''opt.customvis'' field is going to be used.

This field will add extra lines in the visualization part of the .dat file (check the spavisual manual for all supported commands). In example, the USERPLOT function can be added with:
