Rotary Tool?

I’m struggling wtih something that I think should be easy. I was trying to use the follow me like you would creating a sphere but no joy. I’m trying to build a “bolt cap” for an old butcher block. I’ve got the profile built fine. I want to rote the profile 360, creating essentially a small dome with ridges. Anyone have a tip or extension that would help me figured this out? I’ve got a screen shot of an STL file I created by copying and routing the profile about 150 times. It’s way too complicated to run through my printer. Thank you.

Try scaling everything 10x or 100x SketchUp isn’t good handling too small geometry, you can scale it down after making the follow me operation if you want.

Like this?

Scale the model up temporarily to avoid the tiny faces thing and use Follow Me with just a 2D profile of half of it.

Ah, exactly!

It looks like your cap is supposed to be 2-3/4 in. diameter. That would be 69.85 mm. If you are going to 3D print it, model this thing as if meters are millimeters so it winds up 69.85 meters in diameter. Export the .stl file as Meters and open it in the slicer in millimeters. Working this way will preclude the need to scale the object down and will avoid issues with tiny faces. For this example I used a 96-sided circle as the Follow Me path.


In the slicer:

BTW, it looks like you are using SketchUp 2025. Your profile says you are using SketchUp 2018 on Windows 10. Looks like time to update your profile.

Dang, mind sending me that file?

I modified the inside of it. so it doesn’t have the ribs.

Thank you so much. I really appreciate that.
