Creating Sloped & Transition Floors

[SGrisez]

1. I can make a 12" depth sloped floor, but the thickness of the floor is slightly less than 12".  Can I make sloped floors that keeps my depth?  How?

2. Also, on one end of a rectangular floor the floor is sloped at 2:1 and at the other end the slope is 1.5:1.  How can I create this transition floor?

Variable Thickness and shape editing (Mod Sub Elements) will get you there.

[SGrisez]

Can you show me a sample?

When I say 'transition floor', I also mean warped slab.  2:1 at one edge and 1.5:1 at the other edge.  The slab from the top view is a rectangle.

Shape Editing tools should get you there.  Warp away.

Use slope definition or slope arrow.

See above, add void(s) to cut the part sticking out.

Also, if you can use Roofs in lieu of Floors the you can create a Roof by Extrusion then the transition between different slopes will be smooth.

...or like this. no void necessary. smooth transition.

If the above picture is what you are talking about; that was done using a Roof with 2 Slopes Arrows meeting at the hinge point.  No reason a roof can't be a floor. Roofs can be drawn via Roof by Extrusion (cross section profile) as well.

That is essentially Modify sub-element, the same as Moving a point up or down. You will end up with a thinner thickness where the slope increases.  For shallow slopes it may work because the delta is acceptable.

Warped Beams? No Variable Thickness? Boy, I completely misread OP .  But, Yes; Modify Sub Elements will accomplish the same thing without beams if you're not in to that kind of thing.

It does seem a silly to warp beams to get the true thickness of the warped floor. But if you adjust the sub element only you will not get the true thickness.

Thanks so much,

Have you actually measured the thickness?  Because it doesn't maintain when I tried it myself.  Increase the inclination to see the difference more clearly.

I didn’t think it was silly at all. It’s a good technique, and you presented it well, Stephen. Thanks for the contribution. Well done.

I just wasn’t thinking beams.  But, everything you showed can be accomplished with the same results using the Modify Sub Elements. Regarding slab thickness; I tested both methods using a 15x20 slab, and both methods yielded the same slab thickness – which I agree was off by a gnat’s hair. But I had to jack up the units precision to “Micrometer Units” to see the discrepancy.
