The Defeature Tool allows users to remove details form a part or assembly and save the results to a new file that is a dumb solid. What’s a dumb solid, you ask? It’s a solid body without any feature definition or history. This less-detailed model is saved to a separate file and maintains references to the original part or assembly. Why is this type of file beneficial? You can share the model with customers, suppliers, and upload to 3D Content Central. You can share only the information you want to share without giving away all the details of your design. Another benefit is to use this model in a large assembly. The smaller size file helps with rebuild time of a larger assembly, especially if you use multiple parts. Let’s take a look.
Defeature is found under the Tools menu.
For this blog, I am going to Defeature a component.
I opened up this Housing and started the Defeature Tool.
For Defeaturing a component, Step 1 of the Property Manager screen are the Features to Keep. I chose the mounting holes. Select the Next arrow.
Step 2 of the Property Manager screen are the items To Remove. I selected a variety of faces that I don’t want shown. You see here that I selected some additional features. Select the Next arrow.
Once the tool has run, the last step shows that the Defeature was successful and asks what to do with the results. Another window shows you the results (on the right).
The file can be saved as a separate file and has an option to link it to the original part.
Notice the new part doesn’t have a feature history.
If you want to change the part and chose the Link to Original option, a Right Mouse Click will offer the option to Edit in Context which will open the original part file.
The file size is for the Defeatured part is smaller.
