About Attached Flat and Flange Walls
Attached Flat Walls
An attached flat wall is dependent on a first wall. It has any flat shape with a linear attachment edge. An attached flat wall requires an open loop sketch that is extruded as a flat section. You can create a attached flat wall shape for your design using one of the following methods:
Select one of the standard flat shapes
Sketch a user-defined flat shape.
Import a predefined flat wall shape.
For an attached flat wall, click Model > Flat.

Flange Walls
A flange wall is an attached secondary wall, dependent on a first wall. It has an open cross-sectional sketch that is extruded or swept along a trajectory. An attachment edge can be linear or nonlinear. The surface adjacent to the attachment edge does not need to be planar. You can create a flange wall shape for your design using one of the following methods:
Select one of the standard flange shapes, including a hem-shaped flange.
Sketch a user-defined flange shape.
Import a predefined flange wall shape.
For a flange wall, click Model > Flange.
