Once you have downloaded and installed the Snaptrude Manager for Rhino, follow this tutorial video to learn how to import in a Rhino model on Snaptrude and edit it further:
Current Limitations:
Materials applied onto geometry in Rhino will not get exported.
Areas are not calculated for spaces that come in as 'Direct shape'.
Once imported, in the 'Storey Tab', users will not be able to create basement storeys.
Changing the height of the storey once the objects have been imported, may lead to the geometry being skewed and scaled incorrectly.
When users choose to import an object as a Slab, the slab family type can only be assigned in Snaptrude, after import.
Since Snaptrude Walls are disjointed at the junctions, if you import an L shaped wall that is continuous and has no junctions, it will not function exactly like Snaptrude walls.
