About the Creation of Bends from Walls

This topic provides you with more information about the creation of bends with closed extremities on walls.

To create a closed bend, note that:

• It cannot be built with a null radius.
• It cannot be built if there is no intersection with another bend, for instance if a bend is created on an inverted wall. A warning is issued and a maximum extremity is built instead.

• The bends supporting the walls are not trimmed.

• In case the intersection between the bends of the supporting walls is too short, a tangency extrapolation is computed.

This topic provides you with more information about the creation of bends with square or round relief.

Depending on the geometry configuration, this can lead to removing more matter than expected. Indeed, when a corner relief is computed on the whole intersection of the elements involved (bends or walls), the matter is removed till the end of the wall.

Bend with no relief

Bend with square relief

In this case, it is advised to replace the bend corner relieves with cutouts (identified in red in the figure below) to remove the matter to the shape. For more information, see Creating Cutouts.
