SOLIDWORKS Manage 2021 brings new, powerful Bill of Materials (BOM) features. Here’s a short summary of the new functionalities.
Dissolving an item
One of the most powerful enhancements is the possibility to dissolve an item in a BOM, so that that item is replaced by its children. This is especially useful when a sub-assembly exists in SOLIDWORKS only to organize the design in a better way, but does not represent an actual item that will ever be assembled. This is similar to classifying that sub-assembly as a phantom, however, when you dissolve a sub-assembly, it is removed completely from the BOM.
When you dissolve an item, you can choose what happens to child items that already exist in the BOM level where the current item is being dissolved. Typically, one would add the quantity coming from the dissolved sub-assembly to the existing item, but you can also simply ignore it. You can also choose whether manual quantities and custom values are copied or not, and if you want to overwrite custom BOM values in the item receiving the quantity from the child or not.
Note that CAD BOMs (that is, originated from SOLIDWORKS) cannot be dissolved, as they must represent the exact structure of the CAD model, analog to the PDM calculated BOM. In the example above, we created an MBOM by copying a CAD BOM.
Cut, Copy & Paste
You can now cut or copy and paste SOLIDWORKS Manage 2021 BOM items from any record to any other record, as long as the new parent record is checked out. The new clipboard commands can be accessed from either the ribbon or the context (right-click) menu, highlighted below.
Once you cut or copy a record, you can either paste it as a child of the selected record or on its top-level, as a sibling.
Multi-Level Copy From Enhancements
The Copy From command now allows you to select the children that should be copied with the parent item. Until version 2020, all children would be copied.
Add New & Add New From
These new commands allow you to add new items directly from a BOM view, without the need to navigate to different windows or even closing the current BOM. This saves time and mouse clicks. Again, you can access them from either the ribbon or from the context menu.
The New command will create a new empty record, while the New From will allow you to create a new record as a copy of another record.
Replace with New and Replace with New From
These commands are similar to Add New and Add New From, but instead of inserting new items, they will replace the selected record.
