Creating a Mass

You can create a mass to start your building project.

  1. Create a closed sketch of the building as follows.
    1. From the Building section of the action bar, Positioned Sketch .

      Note: You can create a sketch using Sketcher.

    2. In the 3D area, create a closed sketch.
    3. In the Sketcher app, in the Sketch section of the action bar, click Exit App .
  2. To create a shape for the building:
    1. Create a sketch using Positioned Sketch .
    2. Use a command from the Solids section of the action bar to convert the sketch to a shape.
  3. From the Building section, click Building Massing .
  4. In the 3D area, click the sketch or shape to include in the mass.
  5. To change the building height, in the building, drag the Height handle to the desired height.

    Alternatively, type the height in the Height value box.

  6. To remove the building wall, from the Mass dialog box, click Remove Walls .

    Remove Walls is a toggle. The function highlights the toggle when the walls are removed.

  7. Optionally, change the default values for:
    1. Number of stories
    2. Starting Story
    3. Story Height
    4. Slab Thickness
    5. Extend Downward

    Important: You can change the elevation for the bottom of the mass with Starting Story only if there is another mass in the 3D area.

    Your entries for Story Height and Slab Thickness become the default values for every story in your building. After you make the first mass, the system omits these options from the Mass dialog box.

    Your entry for Extend Downward is the distance by which the walls of the mass extend downward beyond the bottom of the primary slab of the starting story.
