Electrical Panel Feed Thru Lugs in Revit 2020

Revit 2020 has a new feature that will please Electrical designers.  Feed through lugs are now incorporated into Revit for your electrical distribution system.  Previously, electrical users had to utilize workarounds to represent this situation in their designs, so this will improve the documentation process and help with the electrical design.

As part of this new feature, Revit has added a new panel schedule template, which is called “Feed Through Lugs Panel“.  This panel is available in the Electrical-Default.rte and the Systems-Default.rte templates.  This panel template is accessible via the Manage tab -> Settings panel -> Panel Schedule Templates.

 

The process to actual set up the electrical panels to utilize the above Panel Schedule is shown below. Continue reading

Component Elevation Changes with Wall Base Offset

When placing components on the face of a wall in Revit, the same component may move differently when the wall base offset changes.  This can cause frustration to the user by not understanding why it is happening.  No one wants to see their component change elevation when they don’t expect it.

Walls can have the bottom offset either up (positive dimension) or down (negative dimension) to raise or lower the base of the wall.  While the majority of the time the wall will be at the floor level, there are many times when the wall needs to be above the floor.  A couple of examples are a wall that sets on a concrete curb, or a wall which serves as a soffit.  The Base Offset parameter for the wall is modified in the Properties palette when the wall is highlighted.

Revit Section Bubble Placed In Text

I get asked about how to place a detail bubble or a section bubble amongst text notes where the actual leader for the bubble is not desired.  The user still wants to have the information within the bubble to auto-update, so the bubble needs to be an actual callout. This is a very common situation,   The following image is an example of a typical situation.

Revit Design Options in Linked Files

It is not uncommon for construction bid projects to have alternate bid items as part of the design.  Revit users will typically use the Design Option capability of Revit to show the alternate bid(s).  This works excellent for the Architect, but it does not work quite as well for MEP consultants.

For the Architect to make it a bit easier for their MEP consultant, it is good for the Architect to create a model elements only view of the alternate bid design option in their Architectural model.  This allows the MEP consultant to reference this view in their model without extraneous information.

Show Existing Architecture But Not Electrical

I have seen the situation where the Electrical designer was working on a remodel project and did not want their Existing electrical devices to be shown in the New Construction phase views.  The existing electrical devices and equipment were only to be shown on views that displayed only existing information.  However, they needed to show both the Existing and New Construction walls and other Architectural elements in the New Construction views.  Revit doesn’t want to do this without changing the default settings.

By default, the linked Architectural elements will show the same phase as the host Electrical file’s view.

  • If the Electrical file’s view has its Phase parameter set to New Construction, and the Phase Filter parameter set to Show Previous + New, you will see the existing elements for both files as well as the new elements for both files.
  • If the Electrical file’s view has its Phase parameter set to New Construction, and the Phase Filter parameter set to Show New, you will only see the new elements for both files.  Existing elements will not be seen for either file.

Control Visibility of Plumbing Fitting Tick Marks in Revit

Single line drawings in Revit plumbing plans (Coarse and Medium displays) show the tick marks for fittings by default.  Some design firms prefer to not show tick marks for the elbows, tees, and other fittings.  Revit has a setting that allows users to adjust the printed size of the tick marks, but this affects all tick marks for all fittings.  I see situations where the designer wants to see tick marks for reducers and couplers, but not some other fittings.

Pipe fitting families can have a parameter added that controls the visibility of the tick marks.  This allows the user to specify which fittings should show the tick marks and also allows tick mark visibility to be different for different projects.

Each Pipe Fitting family will need to be modified, but we will take a look at one family here.

Revit Section Markers Discipline Visibility

When and how Revit section markers display on plan views can be a bit confusing when you are working with multiple disciplines.  With more disciplines involved with a model, the more noticeable and confusing the issue becomes.  This is due to the fact that section markers are discipline-specific and cannot be displayed on all the different disciplines of plan views.

Revit is designed so that section markers will not show in other discplines’ views and this is based upon the Discipline parameter of a view.  Revit has 6 different Disciplines available for selection for a view.  They are:

  • Architectural
  • Structural
  • Mechanical
  • Electrical
  • Plumbing
  • Coordination
