Create Areas Component
The Create Areas component and the other area-related Pro components allow you to work in plan using trimmed surfaces to define and edit your material regions. And areas can be projected to a topo mesh at the end or during(!) your workflow! No more mesh trimming each time you make a change to the topo or to the plan layout. Just keep it all rolling at once. Now this is fluid 3D landscape design.
Area surfaces can be easily edited in Rhino by splitting existing areas with new linework and rejoining (and Merging coplanar faces > MergeAllCoplanarFaces) OR by shifting solid control points in plan (SolidPtsOn). From there, making your hatches is simple. Just get the surface edges, join, and build a hatch in a component from Elefront or Human.
