CAD Model Notes
For modeling we use Rhino 5.0 on OSX. From there we export a Rhino 4.0 model and a Google Sketchup 8.0 model. Sketchup is great because it's a free download and the measurement tool is easy to use. Long-term we would like to move to FreeCAD which looks increasingly promising.
Sketchup 8.0 Export Notes
There is no straight forward way to convert a Rhino to a Sketchup file. Still, the following works reasonably well:
- export and import by layer, this allows us to restore subsystem colors
- in Rhino select by layer, export selected and use the 3DS file format
- in the export settings use Density 0.1, check "Refine Mesh" and "Simple Planes"
- in some cases a higher Polygon density might be required (e.g 0.5)
- in Sketchup create the layer, assign the color and select it for insertion
- then import, select "color by layer" if necessary
Sketchup has the bad habit of inflating the file over time. To reduce the file size do the following:
- open Window/Model Info
- under Statistics click "Purge unused"
