The shape editing tools were designed to allow for moderate slopes and in such cases variances in true thickness are trivial.
Revit roof shape editing.
This also adjusts the position of the roof if the support and the roof are not aligned.
Shape editing tools are used to create flat roof slope.
In order to enable shape editing tools the following conditions must be met.
However more significant slopes will increase this variance.
You will see shape editing tools from in your ribbon contextual tab.
Revit structure you can use shape editing tools to manipulate the surface of a flat non sloped floor or roof by defining high and low points for drainage.
A roof cannot attach to another roof and the roof cannot be a curtain roof.
Revit will issue a warning when a slope significantly deviates from the expected thickness.
Use pick supports to split the roof element at the supporting beams.
Floors must be flat and on a horizontal plane.
Add points manually or create them automatically with split lines.
By specifying the elevation of these points you split the surface into sub regions that can slope independently.
These are available on flat slabs only.
This will modify the form of the roof and allow for customized roof shapes.
First select the roof.
Revit structural project 08 roof 0pen web steel joist framing and modify grid duration.
The shape editing tools display on the contextual tab.
Use shape editing to add internal drains to the roof built using sloped insulation.
On this flat slab you add one or more points and then adjust the z height of those points.
First activate add split line and draw the lines like below.
Floors and roofs that have been shape edited will not report a true thickness.
After you finish creating the roof select it.
This shape editing tools will not appear if you define the roof slope.
