QUESTION

I am working to create a roof for my structure and I see an entry for Baseline in the Roof Plane Specification dialog. What is a roof Base Line and how do alter it?


ANSWER

A roof baseline is the uppermost portion of a roof plane directly above the main layer of a wall. Baseline height does not include the roofing material or ­sheathing, just the framing materials. A roof section's baseline is the line in 3D space around which the roof section pivots as you alter the roof section's pitch. The baseline may also be drawn over a CAD line or at the corner or edge of an existing roof section.

If, for example, you were looking at a ­truss or ­rafter, the baseline would be on the top of the rafter or truss. The baseline would be located at the point where the truss or rafter sits directly above the main layer of the wall the roof plane is resting on.


To hide or modify roof baselines

  1. From the menu select Tools> Display Options .


  2. In the Layer Display Options dialog, locate to the Roofs, Baselines layer and click to remove the check mark from the Disp column to hide these.

     

    Alternatively, you can chang
    e the Color, Line Weight, and Line Style of this layer to more easily distinguish your roof baselines from other architectural objects and CAD lines in your drawing.


  3. When finished making your changes, click the OK button to apply these changes and exit the Layer Display options dialog.
