View Full Version : Sloping roofs/floors in three directions

Good morning,

I am desperatly trying to slope a driveway in three directions. The driveway in plan has all straight edges however the RLs vary. I can break the driveway down into triangular segements. For example the first triangle has on each corner an RL of 51.800, 51.900 and 51.950.

The roof tool will slope planes however the base angle remains horizontal. A swept blend will only allow profiles to be created parralel to each other. The floor tool will only slope in one direction.

I'm sure there is a way to do this, as a lot of contemporary architecture uses these cranked forms. I have been trying this for hours but to no avail!

If anyone had any suggestions that would be super!

Thanks,

Maya

How about a simple sketch showing us what you are after?

Can't you do this with a floor using 'Modify Sub Elements' in the Shape Editing part of the Modify ribbon (available once you have selected your floor)?

Create a floor type called driveway and make sure that the elements are not set to 'variable' in the type properties (or you will end up with varying thicknesses of the floor). Make a level floor at say 51.800, select it and then click 'Modify Sub Elements' to enable you to change the heights of the other corners of the floor: +0.100 and +0.150 to achieve your desired levels. You can add additional points for further modification of the shape so the entire driveway can be one floor (don't have to break it down into triangular sections) with as many height definition points as you wish.

Can sometimes be easier to work in a 3D view to make sure you are selecting the correct points (may involve a bit of tabbing to select).

Hope I have understood what you were after.

For floors/roofs: properties->edit type->edit structure.
