At present, there are two ways to draw reinforcing ribs, side view and top view. There must be boundaries at both ends, and the boundaries must be higher than the rib surface.

1. According to the operation of the stiffener, there are two modes (side view and top view). In the side view, only one line can be created in the sketch of the rib web plane as the upper boundary of the rib, while in the top view, multiple rib axes can be created in the sketch that passes through the upper boundary of the rib and is parallel to the web plane of the part. Notice the difference between the planes where the rib sketch was created.

2. Also, note that there must be borders at both ends of the ribs, and the borders must be higher than the ribs to block the ribs.
