The Toposolid tool defines a topographical element using defined elevation points or imported data.
When viewing a toposolid, consider the following:
Toposolid elements can be cut by other elements. Use Cut Geometry in a Family to perform boolean operations to shape toposolids. Use Split Elements to split a toposolid into multiple toposolid elements.
Slab edge families can be applied to the edge of a toposolid. For example a slab edge might be used to model a curb edge on your site.
Toposolid elements support surface patterns used by the material assigned to the toposolid. See About Fill Patterns for Material Graphics for additional information on defining a surface pattern to a material.
