I want to create a slab on grade. I have setup the structure layers in the assembly editor as shown in the attached image.
I cannot seem to define the layers for the sub-base materials, sand, gravel, stone....
The dialog does not seem to want to accept and material below the bottom thermal layer.
It is my intent to add the sub-base layers to allow revit to display detailed views of the slab on grade as part of the drawing package.
Can someone offer insight into this subject?
Thanks in advance
Tim C.
