Best Practices: Slanted Walls

Follow these best practices when modeling slanted walls.

Generally, best practices for slanted walls follow the same best practices for other wall types. There are some exceptions and some functions that behave differently, as listed below.

The following functions are not currently supported in a model that contains slanted walls.

• Structural analysis
• Slanted curtain walls that are embedded in other walls.
• Selecting the centerline of a slanted wall (for example, when creating a floor or ceiling).
• Square-off and miter Wall joins are not supported for slanted walls.

The following functions work differently than other wall types.

• Energy analysis gbXML export using room/spaces does not support outward sloping walls.
  Note: An energy analytical model using conceptual massing and building elements does support all sloping walls.
• Positive or negative wall slant, as indicated in the Angle from Vertical parameter, is determined by the direction in which the wall is drawn. In the draw direction, right is always positive and left is always negative. See Place a Slanted Wall.
• When attaching the top or base of a slanted wall to a roof, ceiling, or floor, the target element must cover the slanted wall entirely as viewed from above.
• For horizontally split slanted walls, the following functions work differently.
  • Split wall sections don't automatically follow the position of a moved wall section, as with vertical walls.
  • When you are splitting a slanted wall by a horizontal plane, the temporarily-displayed splitting line does not lie on the wall. It will be positioned as if the wall were vertical.
• When you place a wall sweep or wall reveal in a slanted wall, on the Properties palette, for Orientation, select Perpendicular to Face or Parallel to Ground.
• For slanted walls, the Split with Gap tool is disabled for splitting with a vertical plane.
• When creating stacked slanted walls, the constituent walls will have the same angle as the stacked wall. You can't change the slant angle of the constituent walls (other than by changing the slant of the stacked wall).
• Angular dimensions can be used with slanted walls but can't be used to set the slant angle.
• You can flip a slanted compound wall using the spacebar. The wall layers invert as expected, but will not change the slant direction. To change the slant direction of wall layers, use the Mirror tool.
• When you are creating a stair run component, it's not possible to pick a slanted wall as a boundary.
• When copying slanted walls with the Create Similar tool, the wall type is inherited, but the Instance Parameters are not inherited.
• When creating an opening in a slanted, curved wall, the resulting opening will not be rectangular due to the wall geometry.
• After placing a door or window that is oriented vertically in a slanted wall, you must manually resolve the resulting gap between the element and the wall.
