Revit’s Hidden 2D Symbols.

You could be forgiven for not realising that Autodesk Revit has lots of 2D symbols preinstalled, because there not that easy to find. Technically, they belong to the Category ‘Detail Item’ so that’s what we should be searching for when we use the ‘Load Family’ command.

Use this path to see what’s available – Look in the ‘Entourage’ folder.

Once you’ve loaded the ‘Detail Items’ into you project, use the ‘Detail Component’ command to place the family.

Some of these families are Parametric, they come with three types, an Outline and Hatch, just the Outline and finally, just the Hatch.

Of course, you could always create your own. Simply start a new family using the ‘Metric Detail Item’ template.

Create the ‘Detail Component’ family using the ‘Line’ and ‘Filled Region’ tools, or as an alternative, import an existing Autocad drawing.

Why not go a stage further and make your family parametric, combine several families together and control visibility with a parameter:

Select the tree, associate a family parameter, in this case, it’s called “Single Palm Tree visibility” and define it as an ‘instanced’ based ‘Yes/No’ parameter displayed in the ‘Visibility’ group.

Repeat the process for the second variation, select the second family, associate a family parameter, in this case, it’s called “Triple Palm Tree visibility” and define it as an ‘instanced’ based ‘Yes/No’ parameter displayed in the ‘Visibility’ group.

We could enhance the family further by automating the display with a visibility toggle. In use, the ‘=not(Triple Palm Tree Visibility)’ statement is a visibility toggle that automatically displays one family and hides the other and vice-versa.
