Cut plane and braces

I had a problem with how the structural braces are drawn in plan view. The default in Revit is to show the complete brace which isn’t preferred for architectural drawings as it draws the brace through doors and windows. I found a solution here¬†and I’m repeating the post on my blog so I have it handy.

For a column family, you can select the option Show family pre-cut in plan views, in the Family Category and Parameters dialog. When you select this option and load the family into a project, the column displays in a plan view using the cut plane specified in the plan view of the family.

  1. Open a column family or start a new column family.
  2. Click Create tab>Family Properties panel>Family Category and Parameters.
  3. In the Family Category and Parameters dialog, under Family Parameters, select or clear the parameter, Show family pre-cut in plan views.


Columns, beams and braces.

For people using Revit Structure this post in going to be old news. However if you trained in Revit Architecture, this will probably be new information that can be very helpful. I’ve always had difficulty getting certain structural elements to do what I want so that they display nicely in elevations and sections. A recent project I worked on has slanted walls and with the slanted walls came a slanted seismic frame, slanted columns and a few braces. The pushed my use of the structural elements in Revit beyond the mere “post and beam” use that I blogged about in this post.

Families – constraints

Constraining lies at the heart of parametric families. There are 5 tools that Revit has to let you constrain a family.

  1. Locked geometry and linework.
  2. Locked dimensions.
  3. Equal dimensions.
  4. Parametric dimensions (type and instance).
  5. Automatic sketch dimensions.

Families – Lines

This post is a continuation from last weeks posts on families in particular some items the tutorials don’t cover.


If reference planes are the skeleton and labelled dimensions are the muscles of the family, reference lines are the joints in the skeleton. They define which way the parts of the skeleton can bend (rotate) but they can also do more.

Families – Planes

This is the first on a series of posts about Revit families so I’ll take a moment to describe where I’m coming from when I write these. I am going to take for granted that the reader knows how to create families and how to use them in Revit. The reason for this is that Revit comes with some rather nice family tutorials and I don’t want to cover that ground again. Instead I’m going to go over some quick points that I have noticed many beginner tutorials don’t cover.

Going offline

Sorry folks. Due to a sickness in the family, I am unable to put in the time it takes to write a blog on a weekly period. I’ll be posting them as I can but I can’t say how frequent that will be.
