How do I merge shapes/bodies?

I’m incredibly new to this, I’ve never touched a 3D modeling program before and I’ve only explored the app for a few hours so far. I wanted to ask if I can merge different bodies into one? The “union” button looks like it does it but it still has the individual shape outlines and I’d like to remove that…

The Union function is the correct method. Can you expand further about the issue you’re perceiving?

Union works fine! It does what I wanted it to do so I really don’t mind it but I was just wondering if I could remove these outlines…


you can make snapshots without outlines, grids and background in the export image tool.
You can also use the brand new material feature to get great rendering with texture if you are on ipad or MacOS.
