Dear All
I have a 2 way sloping slab. when I take a section through the slab I get a result as fig. (1), but I want the result to be as fig.(2). If I try to rotate the section on section view, I get an error message saying: Can't change plane of Floor Sketch (is there any way of rotating a section view?).
any help would be appreciated.

Floors and slabs have always vertical sides. Rotating section view doesn't help. You need another type of family. Try generic family and model in-place and rotate or a adaptive component.
with generic family I won't be able to use the sub element command as this is a 2 way sloping slab?
If you are just needing it to look a certain way in the section you cut, have you tried the cut profile command under the view tab. I was able to make the end look like you wanted. See picture
You can just Cut The borders with two Voids:
Unlike Cut Profile command , this is a real 3d function.

Hi Constantin. Great help as usual. I think I didn't make myself understood properly. I have attached a sketch of what I need. I understood both your solutions, but I like the slab to be as section 1-1 as per attached sketch. by the way, on your solution 1, using the cut profile, is there a command in Revit which does the opposite(i.e. adds a profile rather than cutting it). Many Thanks in advance.
Hi Constantin. on your second solution I tried to follow your instruction by creating a ref. plane on the slab plan. when I try to create a void extrusion I am directed to a section view. here I can not pick the end of slab to create a triangular section for my void extrusion. is there any way possible at all for you to show your solution on a video clip please. I'll be most grateful.
Q.
is there a command in Revit which does the opposite(i.e. adds a profile rather than cutting it)
A.
Yes, it is such a function : Floor Slab Edge
Architecture >Floor> Floor Slab Edge
You have to made a custom Profile with Angle as Parameter so to be able to fit the slope..

Yes with the cut profile command you can add as well as remove. It is a really handy item for doing hybrid sections.
Hi, you say you have a 2-way sloping slab.
Can you please tell us the elevation levels in each corner.
Is the top surface one even sloped plan.
Are you trying to model a rotated slab and with a section view show that it is rotated.
I'd like to know the end result you are looking for.
The plan view and section view doesn't correspond.
Thank You for getting back. this is basically a car park slab which will be cast flat and then placed on site on a slope. I
have put spot levels on each corner to make it more clearer.
I've made a screencast on the subject of a sloped Floor Slab that is Cut by a Void in order to obtain the desired edge profile....maybe it will help you..

If you intend to use concrete prefabricated elements then a Faced Base Family could be an appropriate solution.
I made a screencast for another post on the subject, but I think it can be useful also for you:

Thanks a lot Constantin for taking time to do the screen casts. I have looked at both screen casts you kindly sent. I prefer your first solution which has helped me a lot.
