Q17.

I tried to remove the Outer Boundary, but I could not select and delete it. Is there a way to remove it?

CAST does not allow you to remove the Outer Boundary once you create it because the Outer Boundary plays a unique role in a CAST model. There is only one Outer Boundary that should exist in your model, and the region inside the Outer Boundary represents the concrete continuum. This means that other CAST objects, such as Inner Boundaries, Strut-and-Tie models, Bearing Plates, Point Loads, and Point Supports, cannot exist when there is no Outer Boundary defined or it is removed. However, there are two situations where you can still remove the Outer Boundary, namely:

  • You press the Esc key during creating the Outer Boundary.
  • You click the Undo button just after you finish creating the Outer Boundary.

You are surely allowed to change the positions of the Boundary Corners. You are also allowed to add and remove Boundary Corners as you want.
