Creating a Reference Plane Grid

Reference Planes Grid lets you create a structural grid that displays on your reference plane and axis system selections and is based on a sketch, a solid body, or a surface body.

  1. In the tree activate the shell and core of the building, or a story product.
  2. From the Building section, click Reference Plane Grid .
  3. Select the sketch for the basis of the reference plane grid as follows:
    1. In the Reference Planes Grid dialog box, click Select Profile .
    2. From the 3D area, click the sketch or lines that are to serve as the basis for the reference plane grid.
  4. Select the reference planes as follows:
    1. In the dialog box, click Select Reference Plane.
    2. In the tree, click each reference plane or each axis system on which you want the reference plane grid to display.
  5. To use a solid or surface body as input, in the dialog box, click the Input Bodies box. In the tree, select the solid or surface bodies that are to serve as the basis for the reference plane grid.
  6. To transform the grid, perform the following steps:
    1. Expand Scale and scale the grid.
    2. Expand Twist and twist the grid.
    3. Click the Select Spine box.
    4. From the 3D area, select a spine.
    5. Select one of the following:

      Option Description
      Project to output planes Projects the grid to angled planes without rotation. The system aligns column points on angled planes to those on the top-story plane.
      Tip: Use this option while creating angled roofs.
      Rotate to output planes Projects the grid to angled planes with rotation. The system rotates the grid to match the inclination of angled planes.
      Tip: Use this option while creating sweep geometry like tunnels or bridges.
