How to add a washer under a bolt
Do you ever add a bolt to your assembly, only to remember that you should have added a washer first?
We fixed that problem with Lightning.
We already added a way to add a washer automatically when adding a bolt (or nut). To add a washer below an existing bolt, just:
- Select a bolt or nut. It doesn’t matter if you select the whole component or just an edge or face.
- Click Add washer in the Lightning toolbar.

If we can determine the size and material of the bolt, we’ll select the correct washer for you. If we find multiple washers or none, we ask you to select one.
Then, we’ll break the existing coincident mate between the plate and the bolt, add the washer to the assembly and add three new mates for you. Magic.
