Answer:
For the correct design of ribs, you should pay attention to the following points:
- The local z-axis of the rib must be parallel to the local z-axis of the surface.
- The local z-axis of the rib must be orthogonal to the xy surface plane.
- The surface type of the connected surface must be a plane.
- The cross-section type of the rib member must be a rectangle.
- In the case of continuous members, there must be a uniform rib type for the entire set of members.
- The material of the rib must be the same as the material of the surface.
