I am receiving the following warning, how can I stop this from displaying in my plan?

"A wall designated "extend slope downward" must connect at each end to two perpendicular walls that extend from it in the up roof slope direction. Each of these walls must be designated a "full gable wall"."


At least one wall or railing  in your plan is incorrectly labeled as Extend Slope Downward on the Roof panel of its Wall Specification dialog.


Only check Extend Slope Downward to extend the roof plane downward over a bumpout, instead of creating additional roof planes. The two connecting walls that create the bumpout must be Full Gable walls.

In the  following image, the bearing wall of the bumpout has Extend Slope Downward checked. The two short side walls are Full Gable walls.

To eliminate the warning

  1. Using the Select Objects  tool, select the incorrectly defined wall or railing.

  2. Click on the Open Object  edit button to display the Wall Specification dialog.

  3. Go to the Roof panel, remove the checkmark next to Extend Slope Downward, then click OK.
