I'm not a fan of the topography object at the moment. Maybe I'm not using it right. But I just don't find it very user friendly, and therefore don't use it.
Here's a few suggestions (major overhaul) that I would like to see:
1. This is the big one. Instead of a topo object being a suface, I'd like to see it as a solid (I would call this new object a Topography Solid ). The bottom of the solid is defined by the 'Elevation of poche base' value in the Site Settings. Surfaces are 'old school', solids are the way to go.
2. When you split the surface of the Topo Solid, it doesn't actually split. But rather creates Topography Surface objects. These Topo Surface objects can then have a thickness and material defined. - This would expand on the Subregion tool.
E.g. You create a Topography Solid. You then split the surface of the solid into let's say landscaping and concrete. You could then set the thickness of the concrete to 150mm and the landscaping (grass) to 30mm. When you cut a section through this, it would look great with minimal modeling effort.
The thickness parameter would kind of be like a pad but you would be able to set a constant thickness over an undulating terrain. The Topography Solid and the Topography Surface would all be part of the same major Topography Solid.
3. Surface points that snap to other objects. - Now irrelevant, due to the new Subregion command.
4. Pad objects are/behave as defined in my post at this link: http://www.zoogdesign.com/forums/php...578&highlight=
5. I would like for carparking lines to actually follow the contours. The problem with the current method is that the carpark rotates with the contours, thus creating a distorted carpark layout. We actually have to dimension carpark layouts for a building application so I think you can see the problem, what a nightmare.
