Load Information

A projector is considered a point load in Braceworks calculations, while the video screen is considered a distributed load; if the insertion point is on, or along, a structural element, it is considered to be a load on that structure. Load information is used for Braceworks calculations and reports (Braceworks required).

Include in Calculations

(Braceworks required)

Includes the projector or video screen in Braceworks calculations; deselect each one to exclude it from participating in structural calculations

Only Rear Projector or Front Projector Screen Type can be included in calculations.
