> Merge flanges/bend zones 
The Merge flanges/bend zones function is mainly designed to assist you in joining different Sheet Metal parts. For example, you can join two Sheet Metal parts with the Merge sheets function and then merge the adjacent flanges or bend zones. The prerequisite is that the elements lie on one plane and touch each other.
After selecting the function, the dialogue for collecting the flanges or bend zones appears. Identify the flanges to be united by clicking near the adjacent edges. After a right-click you can select the flanges or bend zones in the ICN or in the drawing one after the other. Multiple selection is also possible. If you want to remove a pair from the list, activate it with the right mouse button and then select Remove element(s) from list 
.
With Apply or a click with the middle mouse button (MMB) the flanges or bend zones are united, but the dialogue window remains open - in contrast to OK. This way you can select further elements. If you leave the dialogue window with Cancel, the function is cancelled without merging.
When merging the pairs, the system first checks whether they can be united, otherwise an error message appears. As the list is processed one after the other, flanges (or bend zones) can be united several times with different flanges in one step.
(1) Bend zones 1 and 2 are merged
(2) Bend zones 3 and 4 are merged
(3) Bend zone 2 (previously merged with 1) and 3 (previously merged with 4) are merged
(4) Result
