View Discipline

Many items for Revit are well documented within Revit's support help. There are these areas that exist but are not documented well. Within the properties of a Revit View (Drafting, Section, Elevation, 3D, Plan, and RCP) is a Discipline parameter with a predefined list of values. At first glance, the assumption is that it is primarily available for organizing the project browser, but that list is hard-coded and has direct implications on the visibility of objects in the selected view. This is how the Discipline parameter impacts the visibility of different objects and categories in a view.

The discipline for the view and sections, callouts, and elevations tags appearing within the view boundaries automatically filters so that they do not appear across disciplines similar to how they filter for Phase and Phase filter.

Architectural

• Only Architectural and Engineering elements between the Cut Plane and Bottom of the View Range will show in floor plans, and between the Cut Plane and the Top of the View Range in reflected ceiling plans. 

• In shaded views, all elements are shaded.

• Options for Show Hidden Lines are: None, By Discipline, or All

  • Hidden lines will have to be turned on for all Architectural elements in the model. <Hidden> lines for each category will have to be turned off for each category within Visibility/Graphics.

  • Defaults to By Discipline

Structural

• Hides “Non-Structural” walls; however, it will show the doors and windows embedded within those walls.

Mechanical

• All Architectural elements between the Cut Plane and Bottom of the View Range will show in floor plans, and between Cut Plane and Top of the View Range in reflected ceiling plans.

• All engineering elements between the Top and Bottom of the View Range will show in all plans.

• The only Structural elements that will show in plan are columns.

• Sets all categories considered to be Architectural and Structural as underlay, and this cannot be changed.

  • This will not allow the elements to be selected in a selection window.

  • These categories will be halftoned based on your model's overlay settings; however, the Plumbing Fixtures category, considered by Revit to be an Architectural element, is not included.

• In shaded views, Architectural elements are transparent, and engineering elements are shaded.

• Options for Show Hidden Lines are: None, By Discipline, or All

  • By Discipline should be set to see the hidden lines for ductwork, piping and equipment, and will use the hidden line pattern found in MEP settings.

  • None will show any hidden lines in the view

  • Defaults to By Discipline

• Inside Gap and Outside Gap settings for engineering elements are defined using the Hidden Line value of the Mechanical and Electrical Settings dialog.

Electrical

• All Architectural elements between the Cut Plane and Bottom of the View Range will show in floor plans, and between Cut Plane and Top of the View Range in reflected ceiling plans.

• All engineering elements between the Top and Bottom of the View Range will show in all plans.

• The only Structural elements that will show in plan are columns.

• Sets all categories considered to be Architectural and Structural as underlay, and this cannot be changed.

  • This will not allow the elements to be selected in a selection window.

  • These categories will be halftoned based on your model's overlay settings; however, the Plumbing Fixtures category, considered by Revit to be an Architectural element, is not included.

• In shaded views, Architectural elements are transparent, and engineering elements are shaded.

• Options for Show Hidden Lines are: None, By Discipline, or All

  • By Discipline should be set to see the hidden lines for conduit, cable tray, and equipment, and will use the hidden line pattern found in MEP settings.

  • None will show any hidden lines in the view.

  • Defaults to By Discipline

• Inside Gap and Outside Gap settings for engineering elements are defined using the Hidden Line value of the Mechanical and Electrical Settings dialog.

Plumbing

• All Architectural elements between the Cut Plane and Bottom of the View Range will show in floor plans, and between the Cut Plane and Top of the View Range in reflected ceiling plans.

• All engineering elements between the Top and Bottom of the View Range will show in all plans.

• The only Structural elements that will show in plan are columns.

• Sets all categories considered to be Architectural and Structural as underlay, and this cannot be changed.

  • This will not allow the elements to be selected in a selection window.

  • These categories will be halftoned based on your model's overlay settings; however, the Plumbing Fixtures category, considered by Revit to be an Architectural element, is not included.

• In shaded views, Architectural elements are transparent, and engineering elements are shaded.

• Options for Show Hidden Lines are: None, By Discipline, or All

  • By Discipline should be set to see the hidden lines for piping and equipment, and will use the hidden line pattern found in MEP settings.

  • None will show any hidden lines in the view.

  • Defaults to By Discipline

• Inside Gap and Outside Gap settings for engineering elements are defined using the Hidden Line value of the Mechanical and Electrical Settings dialog.

Coordination

• Shows everything as normal and turns nothing off. Used to see all categories regardless of discipline.

• In shaded views, all elements are shaded.

• Options for Show Hidden Lines are: None, By Discipline, or All

  • By Discipline does not work for engineering objects

  • All will show hidden lines for MEP objects, but will not use the hidden line pattern found in MEP settings.
