Creating a Curtain Wall Unit with a Custom Grid
Curtain wall units contain one or more grids. You can define a custom grid
with lines, arcs, and circles, and then convert that linework into a curtain wall
unit.
NOTE Curtain wall unit grids are either horizontal or vertical. To create a grid
pattern with horizontal and vertical cells, nested grids are used. For more
information about nested grids, see Working with Nested Grids in Curtain Walls
on page 1464.
You cannot modify the division definition of a custom grid created from lines,
arcs, and circles. You can, however, assign a different division definition to
it. For more information, see Assigning a Division to a Curtain Wall Unit Grid
on page 1597.
