The spherical domes have been, and remain, one of the simplest forms of tensile structures. The internal pressure produces uniform stress on spherical surfaces, and this is the main reason why they have been preferred.
Other reasons, such as aesthetics, simplicity in manufacturing, etc., have also served to popularize this type of form.
When we use the menu File | New | Spherical dome, the program displays the parameters window of the dome. We must set three values that determine the form of the dome:
- Diameter: This is the diameter of the dome (not the sphere that contains it).
- Height: Height of the dome from the base plane
- Mesh Size: This is an approximate value that serves as a reference for generating the triangular mesh that forms the dome
- Number of patterns: We enter the number of patterns we wish to create.
