Hello. The task is to count amount of several parts with geometry, that are flexible with different lengths described by L parameter and marked as BULK=YES. Total length must be shown in BOM table as QTY_BULK. Any modification of BOM table is forbidden.
Now every assembly component has own row in BOM with its length. If there are several components with equal length, they are shown as one component with that length.
How can I summarize all lengths and put it in BOM as one row?
The only way I found is to use additional bulk item with summation of QTY_BULK parameters of needed components. It counts length properly: if I choose "Edit definition" of this bulk, I see correct summary number. But if I choose "Open", there is 0 or another number I input - and the same number is in the BOM. How to include correct summary number in BOM?
