Multiple Unfoldings

This command allows you to create or update the sheet metal unfoldings of an assembly document.

Creation stages / Use:

Click the icon or select BOM > Multiple Unfoldings... from the drop-down menu.

Set the multiple unfoldings options in the dialog box.
Select the parts to unfold.
Validate the creation of documents with the button.

For a given line, a double-click in the template column allows to select an unfolding template for this part.
TopSolid searches for the biggest flat face. It is defined by default as reference face for the unfolding. To define another reference face, you have to define the origin face of the unfolding positioning command and, if needed, the alignment direction which will be aligned with the X axis of the destination frame of the unfolding.

Selecting a document from the dialog list will create a new unfolding even if an unfolding already exists. If you only want to update an existing unfolding, unselect the part from the list.
Parts with existing unfoldings are automatically “unchecked” in the list. It is possible to force the creation of a new unfolding by checking the box again.

Available Options:

Selection:

This field proposes different quick selection types.

With draftings:

This field allows to generate Drafting with the same choices than the Unfolding (destination folder, drafting options). Three news columns appears :

Existing Draftings : if drafting is already generated.
Creation : allows to choose the draft to generate.
Drafting template : allows to choose the template of drafting.

When the multi drafting is created, by default the part projected is the result of unfolding in detailed representation.
It is possible to project a view of the part before the unfolding into the same darft, by defining a second projection set and selecting the contextual option (Others > Unfolding Projection... ).

Create in:

By default, the unfoldings are created in the source folder. The Specified Folder button allows you to customize the location of documents.

Open After Creation:

This option, checked by default, automatically opens newly created unfoldings.

Update Exist Unfoldings:

If, among the selected parts for the unfolding, an unfolding document already exists in the destination folder, this document will be updated. This is equivalent to opening the document, saving it and closing it.
If no document needs to be updated, the option is disabled.

Delete useless unfoldings:

Candidate documents for deletion are unfolding or drafting documents located in the specified destination folders and which are not parts to be updated.
In the case of drafting , documents in the unfolding folder are also considered.
If no folder is specified by the user, no document will be proposed for deletion.
This option is also disabled if no documents are to be deleted.

Unfold occurrences:

The advantage of unfold the occurrences is that if the part is modified from the assembly, the unfolding will be updated without any intervention from the user.

All occurrences: All unfoldings reference the occurrences of parts in the assembly.
Occurrence of the instance families: Only family parts are concerned.
