Level 1 (TOS) type is TOS (Top of Structure), most of the structure is referenced to this kind of level (has Building Story parameter set to true, has Structural parameter set to true) Level 1 type is FF (Finished Floor), it’s used just for coordination purposes with architectural and other disciplines. Let’s look back and repeat what kinds of Level Types are used:

General Revit ® template settingsīefore we start modeling structural elements, we need to make sure that we set up our structural Revit ® template right and, more important, that our levels and grids are set according to guidelines for levels and grids in structural model. Final product must be appropriate for drawings production, further IFC and other file exports, scheduling / material takeoffs, and structural (analytical) analysis uses. (edited ) This workflow is revised below since material quantities and pour breaks depend on correct division of the model and should not be dependent on regardless of joined or not joined geometry. There are some exceptions, for example, cast in-place walls, columns and beams are modeled to the top of slabs, but with use of Revit ® Join Geometry tool we get it right in the end (as it will be “poured”). General rule is to model everything the same way as it’s going to be built.

Guidelines for horizontal structural elements:

Modeling other (non-structural) walls (in case they are needed for some reason).

Guidelines for vertical structural elements: Practical guidelines for modeling structural elements in Revit ® include:
