Key Workflow Tips
Terrain from contours Import contour lines from AutoCAD (.dwg) → use Patch or Drape to generate a surface. Then run Contour back on the surface to verify accuracy.  
Sections & Make2D Use Section to cut through your model, then Make2D to flatten everything into linework. Export as .dwg to refine in AutoCAD or Illustrator.  Or simply using Rhino plan view for 2D drafting -- actually more intuitive. 
Surface vs Solid Most landscape work stays as surfaces — terrain, paths, walls. Only close surfaces into solids (using Cap or Join) when you need Boolean operations or volume calculations.  
Control point editing Press F10 to show control points on any curve or surface. Drag points to reshape organically. Press F11 to hide. Use Rebuild to simplify a complex curve before editing.
