Adding Curtain Grids

If you sketched a curtain wall without automatic grids (Type-Driven Curtain Element Layout), you can add grids manually.

1. Open a 3D view or an elevation view.
2. Click Architecture tabBuild panelCurtain Grid.
3. Click Modify | Place Curtain Grid tabPlacement panel, and select a placement type. See Curtain Grid Placement.
4. Place the cursor along wall edges; a temporary grid line displays.
5. Click to place the grid lines.

   Each section of the grid (design unit) is filled with a separate curtain wall panel of the selected type.

6. Click Esc when you are done.
7. Add additional grid lines, if necessary, or click Modify to exit the tool.

Curtain grid snapping

When you place curtain grids, they snap to evenly spaced intervals on the curtain wall. For example, as you drag the cursor over a panel, it snaps to the midpoint or to the 1/3 mark of the panel.

When you place curtain grids on walls, sloped glazing, and curtain systems, the curtain grids snap to visible levels, grids, and reference planes. In addition, curtain grids snap to other curtain grids when you select a common corner edge. For example, if you place the cursor on a joined edge between 2 curtain walls, the new curtain grid snaps to an existing curtain grid.
