I am designing a wheelchair ramp which climbs a steep gradient.
The ramp will cut a sloping trench with retaining walls either side.
I have created the Topo surface and the ramp. I need to cut the trench now... How!?
Pad option seems to cut a level slab which creates a wedge void.
Any ideas?
Not sure if this would be the best way to go about it, but maybe you could add points to the toposurface to get the trench.
I've been wrestling with a similar problem today, and as far as I can tell there's no way to do it without Splitting the topo and removing the part where your trench goes. This prevents the topo Fill from drawing underneath the bottom of the trench, but it does avoid any lines in the 'wedge' area.Quote:

Create the pad, and while in sketch mode, You can then add a Slope Arrow to the pad, and define your top and bottom of slope. Then it should cut a sloping trench
>_< I've got so used to using the floor modifiers, I completely forgot about slope arrows! Not that they would help me with my current problem, but hey.
I didn't spot the slope arrow command, thanks! Just to be sure, my ramp has flat resting places which I have modelled on a single ramp. Is this fine or is it best practice to model the ramp as seperate sections. I did try seperate sections but found it hard to lock the height of each new section to the last. :beer:
I'm not sure with a Pad. I don't believe you can have more than one slope arrow heading in the same direction, so the Pad may have to be three pieces. A tip for working with multiple Pads that have to "touch" edges. Put one pad in, and just before finishing the sketch (or come back later and edit it) and select the "common" edge line, and copy it to the clipboard. Finish the sketch, start a new pad that touches, and paste the sketch line from the clipboard, now there eill not be a gap in between the two pads, nor will you get that darned Pads cannot overlap error.Quote:

I'm starting to see Revit as an art more than technical drawing. Sometimes it helps to just hold the brush differently :)
Thanks
My favorite analogy is that Revit is like the game of chess. Its easy and fun to learn how the pieces are supposed to move. It can take years to really learn the strategy and intricacies of the game.;-)Quote:
