Performance tip for curtain wall pattern based components

When working with pattern component families for divided surfaces in a mass, you can create a larger mullion panel family subdivided by smaller sub-panels. The grid/panel segments may be larger, but the geometry subdivision will result in a reduction in file size and improve memory and display performance. 

1. Create the new pattern component family for the curtain wall using the Curtain Panel Pattern Based.rft  as shown below using these values of 8m x 8m x 8m grid subdivided by a 1m x 1m x 1m panel three or more times to achieve 1m panels.
2. Create simple conceptual mass with rectangular extrusion with top profile twisted.
3. Load the new pattern component family for the curtain wall mullion into the Revit Project containing the conceptual mass.
     
4. Apply a curtain wall pattern component family to the four faces of the conceptual mass and select divide surface and in the type selector, select the curtain wall component family.
5. After applying the pattern, this process results in normal memory and display performance especially when rotating the conceptual mass.
