Cannot create concrete walls from bottom level to top level

[Anonymous]

I want to create a concrete wall from bottom level (Base Constraint) to top level (Top Constraint) but every time I set “Top constraint” to a higher level than “Base Constraint” Revit replies with:

    “Error – can not be ignored : Top Constraint is invalid for the level”

Revit imposes me to create my concrete walls from top to bottom using “Base Constraint” as the top of my wall and “Top Constraint” as a lower level.  This is totally illogical to me. I want to create my concrete walls using “Base Constraint” as the level where my concrete wall is based on and attached to and “Top Constraint” as the level where the top of my wall will be attached to.

Questions :

1. Can Revit do that or is that a blocked or unavailable option into Revit?

2. Is there another way to create a concrete wall than using “Wall Type : “Basic Wall Foundation – XX” Concrete” that will prevent this to happen?

3, OR even better, can I create my own custom wall types with available materials and all their characteristics for future automatic Revit’s analysis’s ?

Thank to all and especially to the one who will solve my deep technical problem and help me be able to use Revit and get to enjoy using it professionally!

Hi! can we have an opened image to se your levels names please? to see the full panorama

I recommend you go to the level where is the wall base to avoid warnigs of visualization

with your wall tool in the options bar (the green one) choose the height instead depth

then where says unconnected select the top level of your wall

also if you want to do in the reverse order it's possible

for example:

go to the level 1 

use wall tool check the depth in the options bar

and then choose the base level for example foundation level

You will noticed that you can't see your new wall because it's above of your actual level but in 3d view is visible

take  a look on this link for added info on wall

let me know if the above link is not sufficient.

Duplicate the foundation wall type, rename, go to type properties and change Function to anything other than Foundation.  Then you create walls from Architecture ribbon, not Structure, so that Revit uses Height instead of Depth.
