Parts in Revit allow you to divide certain elements from the model into separate parts. These parts can then be independently scheduled, tagged, filtered, and exported. Parts can also be used to plan delivery and installation processes.

Parts can be generated from elements with layered structures, such as:

·     Walls (excluding stacked walls and curtain walls)
·     Floors (excluding shape-edited floors)
·     Roofs (excluding those with ridge lines)
·     Ceilings
·     Structural slab foundations

Parts are dependent to elements. Parts are automatically updated and regenerated when the original element from which they are originated is modified. Modifications include adding or removing layers, changing wall type, layer thickness, wall orientation, geometry, materials, or openings.

Deleting a part will also delete all other parts derived from the original element.

To create parts from a wall assembly select your Wall and then select the Create Parts tool.

This will then separate all the components of your wall into Parts.

When you convert your wall into Parts check the properties dialog box and make sure the Show Shape Handles box is checked so you can then manipulate each separate part.

However when you do edit the shape handles for a part in a 3D view you'll notice that the part is not manipulated in plan views or elevations, only in the 3D view.

You can also divide parts to represent sheets of gypsum board or Plywood by selecting the Divide Parts tool and using the draw tools to sketch the divisions.

You have to change the Work Plane to the face of the part you want to divide.
For example the sheathing. When you sketch your division lines make sure your sketch lines project to the outer wall profile line (the blue hidden line), otherwise you'll end up with only one closed loop.

After you have finished dividing your sheathing you can Add or Remove these division lines to other assembly parts.


  1. Hi Scott, how do you show all the parts in all views. It only shows to the view that you created.

    Thanks so much!

  2. Try creating a view template based on the view you want to emulate, then apply the view template to the other views.

  3. note in all views, 3D/plans/section etc. you can make the parts appear. in the view properties you have the option to show parts, show original or show both. handy if a part change wants to be seen in multiple views.

    Note if you do clash detection and you export as an IFC or navisworks file as parts. the clash will show up on each part. eg a wall has 3 layers. a clash test finds a steel clashing with a wall. if the wall is parts that will register as 3 clashes.
