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.
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.
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.
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:
When working with a multi-story building, it is common to have identical electrical items on multiple floors and the designer desires to have the same circuits for those items replicated on each level. Doing so creates consistency between panel board circuits and reduces labor for circuiting each floor. An example of this is the restrooms, janitor closets, elevator lobby and other service areas in the core of a building where each of those rooms will have the same electrical needs for each floor level.
It is possible to copy the electrical devices and equipment from one floor level to multiple other floor levels and replicate the circuits for the new items. The electrical devices that were circuited together in the first level will be circuited together in the other levels. The Rating, Frame, and Load Name for the replicated circuit(s) will be the same as the original circuit(s).
Most Revit users have heard that Autodesk has released the 2019 versions of its various software packages. Autodesk has included a lot of nice enhancements with this release and delivered on many of the user wish list items. While there are still many improvements to be made to Revit, I am pleased with enhancements in this release.
I am sorry that my blog has not been updated for a couple of months. I just relocated to Oklahoma City, Oklahoma so I have been quite busy between my work and my move.
With that said, I need to mention one of my pet peeves. That is using Detail Lines on plan views of Revit instead of using actual model elements. I was talking to an engineer yesterday and they were complaining about architects providing them Revit models to use that have a great deal of useless detail line information. Using “dumb” lines in Revit to represent items that should be shown as model elements (especially walls!) is a poor solution in Revit. Don’t pretend to “do” BIM and then use detail lines like this.
Electrical symbol legends are a critical part of electrical design documents and everyone wants to have a Symbols List which automatically updates to show the actual electrical symbols that are placed in a project. That way, the only symbols that are on the list are ones that are actually placed in the model and the list does not include many unused symbols. It is actually possible to do this. When an electrical item gets added to the model, the symbol gets added to the symbol list.
It is that time of year that my Autodesk subscription is up for renewal, so it makes me think about the latest pricing system that Autodesk has been implementing lately.
I had been on the “Subscription” plan for years, but that name was changed to be called the “Maintenance” plan in 2016. The new “Subscription” program is entirely different than the old subscription program even though it has the same name. Yes, that can be confusing.
When designing buildings, we all know that we often get walls that are non-orthogonal and at various angles to the sheet. With those walls, we often want to get an elevation that is parallel to a particular wall. It is actually easy to do.
Revit 2018.2 was just released and it has a nice enhancement to the Project Browser that can be easily missed. With this release we now have more options available when we desire to expand or collapse information in the Project Browser.
Prior to Revit 2018.2, your only option to expand items in the Project Browser was to pick on the plus sign (+) next to the section’s name to expand the section and show additional information or the minus (-) sign next to the section’s name to collapse the section and show less information. You still have those options, but the following menu is now available when you right-click over any of the sections in the Project Browser.
When adding piping system to a Revit model, it is desirable to label piping systems with their system type so that you see text on the piping line. Some examples of this are HW for Hot Water, CW for Cold Water, and S for Sanitary Waste.
In AutoCAD, piping systems are typically shown by drawing a line with a specific line type that displays the desired text. This works fine since the lines themselves contain no data and are just symbolic. Revit does not allow line types with text in the line like is allowed in AutoCAD. However, Revit makes it super easy to label piping systems with the appropriate text. I believe that the net result is the same, if not better.
