Creating sections in a Revit model is key to creating a quality 3D model, and that includes creating sections that are simply used for design verification. Construction documents typically include sections, but users also use a lot of temporary sections for coordination and verification. A problem with temporary sections is that you don’t know who created the section and the purpose for the section. As a result they tend to stay in the model because no one really knows if they can delete the section.
I previously wrote a blog article about creating Working Sections which helps with this situation. However, the working section can be further enhanced. This article will address 2 key features for improving the working section:
Who created the working section.
Apply a user’s specific settings for the working section.
Customization has always been a mainstay of design software, especially with the Autodesk products. Customization of Revit for the user/non-programmer is finally here with Dynamo. Dynamo has been in development for some time, but has been gaining momentum among Revit power users. It really opens up the door for users to achieve more functionality through the open-source visual programming extension for Revit. It provides similar opportunities to the Revit user like AutoLisp did for AutoCAD users.
When creating Revit families, it is important to easily see the entire family model in plan view while you are creating or modifying the family. While this may seem obvious, by default Revit does not necessarily provide this ability. You may add some information, such as an extrusion, to the family and have it “disappear”. I have “been there, done that” when I added an extrusion based upon a higher reference plane and then had it disappear when I finished the extrusion. If you don’t understand what just happened, it can alarm you and frustrate you.
As I work with electrical engineers who are migrating to Revit, a common question that I get is “How do I create one-line diagrams in Revit”. One-line diagrams, also called single-line diagrams, are an important part of electrical drawings for construction documents, so it is a subject that needs to be addressed. They are a simplified method of representing a 3-phase power system that shows distribution boards, switchboards, transformers, panels, breakers, etc., with lines illustrating the connectivity of the components of the distribution system. The diagram is not just for physical construction of the building’s electrical system, but developed by the electrical engineer during early stages of design.
The problem that you run into with creating one-line diagrams inside Revit is that the one-line diagrams are generally created before the equipment is actually placed in the Revit model. The electrical engineer will design the building’s electrical system by developing this diagram, then placing the electrical service equipment based upon the diagram.
Unfortunately, Revit does not provide a way of coordinating the one-line diagram with the actual electrical components placed inside Revit, either before the electrical equipment is placed or after the equipment is placed in the model.
There are times working within Revit that Masking Regions are needed in order to hide/cover model information within a project file. There can be various reasons for this, so I won’t discuss the “why” you would do it. You will recognize the need when you confront it. However, when working with Masking Regions, it is always good to know the guidelines and rules for how they work.
Following is an illustration of a Masking Region covering part of a simple model.
Autodesk introduced dependent views to Revit several releases ago and they have been a popular feature when you have a large building with multiple units/areas in order to show the entire floor plan at a scale of say 1/8″=1′-0″. When they were introduced, they were great as they allowed us to break up a large floor plan into manageable units and control the visibility of all units by only modifying one view. We were able to get good consistency and increased speed, along with having view reference tags for adjoining views. I thought is was a great feature.
However, is the use of dependent views still as important at it was when they were introduced? My belief at this time is that they are not as important for everyone. I think some users will get good benefit from them, but others will get benefit from not using them.
As a company moves into using Autodesk Revit for the design of buildings, they quickly learn that families are an important part of the process. Families represent entities within a project, such as walls, doors, windows, furniture, water heaters, drains, sinks, condensers, air terminals, receptacles, electrical panels, light fixtures, etc. Revit provides many families with the software installation, but there are never enough or they never look or function the way that the Revit user’s organization desires. As a result, custom Revit families are created for use within their organization.
Unfortunately, many organizations utilize inappropriate people to create these custom families.
