Why can’t I Insert Forming Tools into my SOLIDWORKS Sheet Metal model?

Article by Mehdi Rezaei, CSWE updated January 17, 2018


SOLIDWORKS Forming Tools are found in the Design Library and are used to form sheet metal parts. In the following image, you can see how a forming tool is dragged from the Design Library onto the sheet metal model to form the part.

Forming Tools for Sheet Metal Models

From time to time a customer will contact us to ask why a forming tool can’t be inserted into their sheet metal model. Quite often they receive an ‘Are you trying to make a derived part?’ warning message when dragging a forming tool into their SOLIDWORKS part:

Warning Message when using a Forming Tool

This warning pops up because SOLIDWORKS considers the dragged file as a Part file. As we know from multi-body design techniques in SOLIDWORKS, a part could be imported into another part in a similar way as importing components into assembly files. This warning allows two choices:

  1. Either select Yes, so that the forming tool will import into the main part file as a derived part;
  2. Or select No, and SOLIDWORKS will open the forming tool in a separate part file.

Either way is not what we are looking for. We are trying to form our sheet metal with this tool. So, let’s see what has gone wrong that this warning pops up.

Specify your Forming Tools Folder

The point is that SOLIDWORKS should know that this file is actually a forming tool so it can be used for that purpose. If we right-click on the “Louvers” folder under Design Library, there is an option called “Forming Tools Folder”.

Check off the “Forming Tools Folder”

This option needs to be checked off so that SOLIDWORKS knows any file under that folder is supposed to be used as a forming tool. Instead of carrying out this process on all your folders one by one, you can right-click on the top folder called “forming tools” and check off that option. Then it will allow you to select all sub-folders as well.
