Create slope in floor a different way then adding height to points?

I am trying to make a topping slab that drains water at a minimum of 1/4"=1' to drains. When I use a floor, I can only change the height of points and its not easy to calculate the elevation at odd points. Also if the points aren't perfectly accurate, the floor creates more triangulated surfaces then needed. What I'm looking for is the ability to make an entire topping section slope at 1/4" and be able to cut its boundaries any way I want and keep the 1/4" slope.

Just use the Floor's Slope Arrow to define the 1/4" Slope.  

 

...Wait a minute. I don't think I'm following you at all.  Sounds like you are shape editing a floor.  Can you post some pictures illustrating what you are trying to do?

If you are trying to do what I thing you are trying to do (e.g. avoid having to manually calculate perimeter point elevations), I would cut a four-sided shaped floor to the shape you needed it with a void(s).

...still, the as-built is going to have control joints off of the corners.

I'm now trying to use a floor with a slope arrow - here's what I get: image.png

When I cut a section through the floor it gets the slope right but its lifted above the level for some reason:

Now when I make a roof, it starts at the level, but I have variable turned on and it's bottom extents won't follow the level

Please link me a tutorial on how to make voids in floors. I've now looked at 3 youtube vids and none explain it. I try to make a mass in place, create the lines and form a void but it says its needs something to cut - I don't see an option to select something to cut...

Create an In-Place Component -- a Void. Cut Floor before closing out of In-Place Component Editing Mode.

Dude you can't select the floor when you click cut when making mass in place. I go to Massing and Site tab, click "In-Place Mass", draw rectangle, select rectangle, click create form = void, go to elevation pull arrow to create thickness, then click cut and I can't click the floor

Draw the floor as a rectangle so that your slope arrow does not make a mess.  Then use Vertical Opening tool to cut around to make the shape you want.  It is a bit easier than using a void.

I got it now - you go to architecture tab, click component and drop down to model-in place...

Where did the idea of cutting a sloped floor to shape - rather than trying to slope a shaped floor - come from? That's brilliant.  I wish I had thought of that. 

 

...oh wait; I did think of that. I see I suggested that approach in Message #3 -- with pictures.

True but the big game changer was the vertical opening command I was not aware of

Yeah, but where did the idea of cutting a sloped floor to shape - rather than trying to slope a shaped floor - come from? Vertical Opening is only a means to an end, as is using an In-Place Component Void -- which you didn't seem to know about either until I explained it to you in Message #7.  The only reason to use either, is to do what I suggested in Message #3 -- which you hadn't even thought about until I suggested it.  Heck, if it weren't for ME, @ToanDN wouldn't have had anything to repackage.  In fact, I should really get credit for his contribution as well.

@gnarkill283: I just looked at @ToanDN's video. A unidirectional slope? Really? That’s nothing like I imagined your challenge to be. You don’t even need to use the Vertical Opening tool. Just extend the Slope Arrow beyond the sketch boundary. You can do that. No need to add the extra step of creating a four-sided slab to just turn around and slice it up using some "cutting" method. Obviously, you know where the bottom of the slab is. So you know where the Slope Arrow begins.

I love the way you guys take the time and go to the effort of creating drawings to help communicate your answers... You and ToanDN do it all the time.  George
