Creating and Using Construction Grids
To add a construction grid parallel to a beam or wall, select Parallel-To-Beam/Wall, then enter the offset distance between a reference beam or wall and the construction grid. Note that a value of 0.00 for the distance is permissible; that would be used to add a construction grid exactly in line with an existing beam. Click the Add button and then click on a beam or wall. If zero was used for the offset, the construction grid will be added in line with the selected beam or wall. If a non-zero offset was used, two parallel guide lines will appear, parallel to the reference beam or wall, at the offset distance specified. Click on either of the parallel guide lines to identify on which side of the beam the construction grid should be added.
To add a construction grid parallel to a grid, follow the same steps as for adding one parallel to a beam or wall, but select Parallel-To-Grid instead of Parallel-To-Beam/Wall, and select an existing grid line when prompted instead of selecting a beam or wall.
To add a construction grid at a specified angle through a point, select Point-Angle, then enter the angle at which the construction grid should be added and the offset distance from that point. Use zero as the distance to make the construction grid to pass through the point. Use a value greater than zero to create an offset from the point. Click Add and then click on the point through which the grid is to be added. If zero was used as the offset distance, crosshairs that indicate the angle will appear. If a non-zero offset was used, four lines will be drawn at the specified angle and offset distance. Click near the line representing your desired construction grid.
To add a construction grid between two points, select Two Points. No numeric input is. This option simply allows two existing SnapTo points to define a new construction grid. Click Add and then click on the two points through which the construction grid is to be added.
Construction grids can be deleted singly by clicking the Delete – Single option in the Construction Grids dialog, then clicking on the construction grid to be removed. To delete all construction grids, select the Delete – All option.
