MODELING A GARAGE RAMP

[Anonymous]

I'M WORKING ON A MULTI-STORY GARAGE WITH A COMPLICATED RAMP SYSTEM. I'M HAVING TROUBLE MODELING THE CORNER SECTIONS WHERE THE RAMP TURNS 90 DEGREES AND SLOPES UP AT A 6 PERCENT GRADE. DOES ANYONE KNOW THE BEST METHOD? THE RAMP NEEDS TO HAVE A CONSTANT THICKNESS OF 8" (A SLAB OF CONCRETE). I'VE TRIED A MESH, WHICH GIVES ME THE SLOPE I NEED BUT CAN'T SEEM TO GIVE ME A CONSISTENT THICKNESS. I'VE ALSO TRIED A ROOF BUT I HAVE NOT BEEN ABLE TO GET THE COMPOUND SLOPE (BOTH TURNING AND RISING) ANY ADVICE? THANKS

Have you tried using the ramp object which is under the special constructions lib.? And some images might help us understand what you mean.

Actually, the ramp objects (three of them) are in
Concrete->Ramps.
It sounds like an interesting problem.
Please post some images to show us
some of the details of the problem.

The mesh can do the trick depending on how fussy you want to be about the constant thickness.

1. Get the top surface the way you want it.
2. Make a copy of the mesh and lower it by 8".
3. Subtract the lower from the upper mesh.

The result will be a little thinner than 8" due to the slope. To get this a little better you can make the vertical offset a little greater (thickness divided by the cosine of the slope) or you can offset horizontally in the general upwards direction of the ramp (thickness times the sine of the slope).

You could probably get it all exactly 8" thick if you were willing to tweak the lower mesh to accommodate the varying slope but this sounds like a nightmare to me.

Full precision probably requires GDL scripting or modeling tools that are not part of the standard set (perhaps ArchiForma or MaxonForm?).
