If I have a cylinder and a half-sphere, for example, like this:


Which is the best/quickest way to scale the half-sphere to match the size of the cylinder maintaining the shape of the half-sphere? So that when I bridge them together I get completely straight lines?

  • $\begingroup$ I edited the "weird results". Its just the half-circle resizing not the way I want or getting inmense. with the half-circle selected I tried (I think) all the snap options without effort. $\endgroup$

  • $\begingroup$ Did you try setting Snapping to Vertex, Closest, pressing Shift+Z while scaling to scale by 2 axes only and hovering over corner vertex of the cylinder? $\endgroup$

1 Answer 1


Assuming nothing is centered or aligned (but rotation is consistent), use Snapping >> Vertex >> Active.

1.) Select a bottom vertex with which to align the half-sphere. L to select connected vertices.

2.) Drag it over to snap it to its "sister" vertex.

3.) Reselect the vertex and Shift + S to move Cursor to Selected. Change the Pivot Point to 3D Cursor.

4.) Now, select the opposite vertex (make active) and L to select connected vertices.

5.) Scale to "sister" vertex.
