How to make weld lines smaller

I’ve been working on my game and all, when I noticed I needed to weld a bunch of things together. The weld lines are really big on the small parts and everything needs to be welded onto a single coherent part. So I looked to make the weld lines smaller, in short; couldn’t find anything.

Any help would be appreciated, thanks.

Go to the “Model” tab. On the right side, you will see a section called “Constraints”

Change the “Scale” property in this section.
