Building Components as Building Pads

[Anonymous]

How wonderful would it be if floors, walls, stairs and ramps (even roofs) could have a Yes/No instance parameter to work like building pads. With this function the topography would automatically fill in between foundation and up to the nearest floor and also we would be able to create fully underground basements, tunnels etc. without using 2D filled regions in every section view.

Please provide a 'check box' (similar for Walls becoming 'Structural' or 'Room Bounding') for Floors to act as Pads and cut the topography below.

Pads are like a specialised kind of a floor but without the flexibility of the floor. Why not simplify the system a bit by getting rid of pads and giving the floors the ability to cut into the topo surface? The UI for this could be implemented as a simple checkbox property that would make the floor act like a pad when ticked but we would still have the ability to shape the floor.

I often create a pad just to cut the topo surface, then I place a floor over the pad and hide the pad. Maybe I'm just odd like that 😉

It would be great, if this would then work for slab edges an foundations, too!

In the early stage of design, using building pads are pretty complicated and has restrictions. Usually, I use stairs, floors, and ramps to check the position of the necessary building pad. It would be good if I could convert those into building pad.

Perhaps a dropdown in the floors/roofs properties for 'topography interactions' with options like

- none   = does not interact with topo

- cut = cuts the topo but does not fill gaps between the topo and the element

- cut and fill   = cuts the topo and fills gaps between the topo and the element

- covered  = the topo is allowed to cover the element (for example the roof of an underground parking lot)

You could then combine a floor with 'cut' on level -2 and a floor with 'covered' to create a tunnel.

We could then use the already existing tools in roofs and floors (slopes, modify sub elements) to create complicated shapes.

Clearly there'a an interest in this topic. Autodesk, please look into this idea.
