The Surfaces From Edges feature allows the creation of Surface bodies in Ansys DesignModeler that use existing body edges, including Line body edges as the boundary. Edges should be chosen such that they produce non-intersecting closed loops. Each closed loop will create a frozen surface body that contains a single face. The loops should form a shape such that a simple surface can be inserted into the model. Examples of simple surfaces are planes, cylinders, tori, cones, and spheres. Simple ruled surfaces can also be created. After a surface has been generated, you can choose to flip the normal of the surface by setting Flip Surface Normal to Yes. You can also choose to set thickness in the Details View.

Illustrated below is an example of a planar surface.

Illustrated below is an example of a twisted surface.

Note that sometimes it is impossible to generate a single surface that will span the closed profile of edges. In these cases, Ansys DesignModeler may still generate a Surface body consisting of multiple faces. When this happens, the faces that get generated are not guaranteed to remain persistent. By modifying the source edges used in the feature, there is no guarantee that the same number of faces will be created or stay in the same location on the body. The Surfaces From Edges feature will be marked with a warning alerting you of this occurrence.

Illustrated below is an example of a Surface Body containing multiple, non-persistent faces.
