Incision with Adding Material and Incision without Adding Material |
Scroll |
The Add Material option allows you to specify whether the incision should be built with or without adding material.
Incisions with and without adding material built with the use of the same bend base line and base face are different in the following ways:
•the rectangular shape of the incision projection onto the base face,
•the shape of the unfolded incision.
As an example, consider an incision the source element of which is shown in the Figure.

a) |
b) |
Incision source element: a) isometric projection
b) projection of the source element onto the base face
The results of the incision construction are compared in the Table.
Incisions with and without adding material
(the bend base line is shown by a thick line, the projection of the source element is shown by a dashed line)
