Create structural floors in Revit

00:03

In Revit, you create floors by defining their boundaries, either by picking walls or by using drawing tools.

00:10

When floors are created, they are offset downward from the level on which they are created.

00:16

Take note that architectural floors and structural floors are essentially created in the same way.

00:22

The main difference is that structural floors create analytical models and structural parameters,

00:27

and architectural floors typically have more finish information.

00:31

On the Structure ribbon, in the Structure panel, expand the Floor drop-down and click Floor: Structural.

00:39

When you do, the ribbon changes to the Modify|Create Floor Boundary contextual ribbon,

00:45

and in the Draw panel, Boundary Line is selected by default.

00:48

Expand the Type Selector and select the type of floor you want to create.

00:53

In the Draw Panel, Select Rectangle.

00:57

In the Properties palette, you can specify the Level and a Height Offset From Level, if necessary.

01:04

Also, since this is a structural floor, Structural is selected by default.

01:09

To define the floor, move the cursor into the drawing area and click grid intersection 1A to specify the first corner of the rectangle.

01:18

Then, click grid intersection 3C to complete the rectangle.

01:23

Notice the double lines on the top horizontal boundary edge.

01:27

This indicates the span direction of the floor, which you can change from the Draw panel by selecting Span Direction.

01:33

Once the sketch is complete and the floor is spanning in the proper direction, click Finish Edit Mode.

You now know how to easily create and modify structural floors in Revit.
