Component Areas of Basic and Composite Elements

For most elements, the calculated area is the projection onto the virtual plane that runs through the center of the component.

The following table gives details about area calculation for each element type.

Basic or Composite Element

Which Plane is used to Calculate Projected Component Area?

Regular Straight Wall

The vertical plane that runs through the center of the component.

Column without Veneer

No component area is calculated.

Column with Veneer (circular)

Circular column with veneer: The plane of the centerline of the veneer component.

Column with Veneer (rectangular)

The program calculates the veneer as if it were divided into four parts as shown, and the vertical plane of each is used.
