Canted Walls Tip ! Use profile in wall definition.

Think light house where the walls tilt inward to form a cone shape if you will.

In the wall definition table at the far right is the Profile column.
This is where you select the profile (you may need to create a profile) to have walls other than vertical.

For outside taper walls (from ground to top of wall) have profile base at bottom and slope (angle) at the right side.

Think of a right triangle with the 90 degree angle at the lower left and the vertical line on the left running up (vertical).

To get profile to show for the entire height of the wall, you must make the profile height 1.5 times the height of the wall.

Ex: You have a 2x4 wall 8' tall.  You want to show a canted / sloped wall with a 12" base tapered to 0 at the top.
Create your profile with a 12' tall vertical line a 12" long horizontal line at 90 degrees to the base (bottom) of the 12' vertical line and then a line for the right side of the 12" base line connecting to the top of the 12' vertical line.
Think of a gable end split into 2 vertical right triangles. The split line represents the vertical edge of both the left and right triangles.  You want your profile to be the right side triangle.

Have fun,
