Placing object on curved surface
-
Hi all,
I have a ring-like object and on the inside of this ring I want to place a dome. The problem is that I don't seem to be able to place the dome accurately on a specific location on the ring. Does anyone have an idea that might help me? It is eventually for 3D-printing, so the object needs to be solid (I use Solid Inspector2 to check this).
I have attached a simplified test file and a printscreen of my attempt to give an idea what I want.
(I have Sketchup pro 2018 and I am a new to Sketchup and thus not very competent.)Thanks!
Test file that should include the ring and a dome.

For all that if you don't want make one by one
something like Components onto Face by Chris Fullmer
but you must have the minimum same number of faces like that you want of domes!So maybe you must subdivide the existing support (for have a smooth surface), and find a trick for multiple selection of faces!
(maybe select by color/material) -
Thanks! This helps at least a little with placing the dome on the surface. But Sketchup doesn't seem to recognise the ring and the dome as a single solid piece.

Can you post your file in V6 (Save as)
because I can't upload it! -
Thanks for all the replies! Maybe I didn't state the question clearly, but I want just a single dome that I can place on a fixed position on the ring. I need to make several copies with different ring sizes, but the dome should be placed at the same location on each of the rings. The issue is mainly the curved inner part of the ring which makes it hard to place the dome correctly. I think the problem is that the straight bottom part of the dome doesn't match the curved surface of the ring. For now I try to position the dome manually as good as possible and than use ´outer shell´ to make it a solid. But is there an easier way of doing this?
@Pilou, I have attached a version 6 file of the example. Hopefully you can open it now.

Geometry is made up of flat faces, not curves, so by turning on hidden geometry you can see the flat faces.
Make the dome a Glue to component then it will stick to one of the facets of the curve.
If you must sit it spanning two segments, then you need to make it taller and set it into the face and use solid tools or Intersect to cut it to fit. It's usually easier to set your geometry to line up as you want it.
Note the reversed face, I used orientate faces to reverse it before grouping.
So once you have your glue to dome, just place it and use outer shell. -
Wow, perfect. This is what I want. Thanks!

After this very cool tutorial you can use any plugins (or not if you have the center of the ring's circle for a Move / Copy rotation)
