    Terrain - Punch Hole

    I use similar workflows on most terrains but they all vary slightly as it depends on the information supplied and obviously the design. If I'm given contours, then I use the terrain tool but in most jobs the terrain will change from the existing to new depending on the design. So if the terrain is not too undulating then I draw a surface extending beyond the plan extents, convert to a nurbs object and use the reconstruct tool to divide it up. I place plan surfaces of the buildings and structures to their levels (separate layer) and then I show controls on the nurbs surface and with the 'perpendicular to reference' toggled on, I move the points up and down to close to the building base plates until I'm happy. Then I chop up the nurbs surface for different materials. The roads are usually one piece so I move that down (say 120mm) and colour it to say asphalt. The nurbs surfaces are all smooth so selecting edges is easy for copying and pasting onto a new kerbs layer from which I can sweep the kerbs. When I have ramps or have to create other surfaces etc., I use either the 'Ruled Surface' or the 'Loft' tools. As I said they all vary but this one is fairly typical but FormZ always has a tool or process which works. I have even used subdivision on terrains which were generated from the terrain tool but you need to keep the amount of faces to a minimum in relation to the terrain size so you have control. Des
