In this lesson, we will add a Curtain Wall to Floor 2.

A Curtain Wall can be simply understood as an exterior enclosure system of a building, usually composed of aluminum frames and glass panels.

1. Open the Curtain Wall Tool

Double-click the Curtain Wall icon on the Toolbar.

2. Curtain Wall System Settings

In the Curtain Wall System Settings dialog, set the parameters as shown below:

• Reference Line: select to Boundary Frame Face

• Place Boundary Frames: select Inside Boundary

3. Scheme Settings

Next, go to the Scheme section and set the following parameters:

• Width: 1000

• Height: 1500

Notes:

• Change the panel type to Main Panel or Distinct Panel

• Click OK

4. Draw the Curtain Wall

Draw the Curtain Wall from left to right.

Press F5 to check the model in 3D view.

Copy the Model to Floor 3

At this point, we have completed the model for Floor 2.

Now, we will create the model for Floor 3 by copying it from Floor 2
(similar to the method used for Floor 2; you can review the tutorial on modeling Floor 2 if needed).

In the Edit Elements by Stories dialog, I will slightly adjust the selections:

• Uncheck Stair and Railing
  (because this building has only three floors, so there is no staircase on Floor 3)

• Add Curtain Wall

• Click OK
