Handset Designer provides both rectangular and round Column drawing shapes. However, Handset Designer only draws Formwork around and counts Formwork parts for rectangular Columns.
The Panels and Fillers for rectangular Columns are specific to Columns and have different part numbers. The Column Panels and Fillers have additional structural elements to support higher pour rates.
Rectangular Columns have four properties: top elevation, bottom elevation, height, and width. In addition you can choose to use pilaster forms, which in effect means changing the shape from a Column to a pilaster.
