Structurally, pilasters are columns that connect to one or more walls. As such, they use much of the same logic as a rectangular column. In fact, the rectangular Column and Pilaster display the same shape on the Drawing Page.
Pilasters are intended to be used as transitions from one or more Walls to another. Complex T or Y intersections are great uses for Pilasters. For two Walls that vary in thickness, you can use a Pilaster to transition the Wall from one thickness to another.
Pilasters have elevations that can differ from Wall elevations. Differing elevations often require custom Formwork. For these situations you will need to review the drawing and resolve any drawing warnings. For more information on creating custom Formwork, refer to Editing Formwork. For more information on drawing warnings, refer to Correcting Formwork Drawing Warnings.
About Pilaster Forms
By default Pilasters are formed using Pilaster forms. You can change this option to use regular Formwork Panels and corners by setting the Use Pilaster Forms option to False in the Shape Data popup of each Pilaster shape. Setting this criteria on each Pilaster shape enables you to have some Pilasters that use Pilaster forms and others that use regular Formwork. The default may be changed in the Formwork Options dialog (refer to Formwork Options for more information).
Note: If you set Use Pilaster Forms to True, but the Wall extends out longer than the Pilaster form, Handset Designer makes the design with regular Formwork Panels and Fillers.
About Pilaster Ties
If the Pilaster is large enough that a single Panel will not fit, Handset Designer fits multiple Panels or Fillers into the space and ties them together using a Formwork Tie. The vertical Tie frequency and wedge bolt materials are the same frequency used for the same height Wall.
