I have used Sketchup for around 10 years now. I have been a shop subscriber for 2 years. Making Spheres has always been a pain. The follow me tool is unreliable. I can use it on a basic right angle corner with a 1.5 mm radius curve but if that corner is a 1.5 mm curve it wrecks the geometry. Maybe it’s an issue with Shop. I just wanted to round the edges of a button with a 1.5 mm radius curve along 3 converging edges. Rounded along X,Y, & Z basically. The last straw for me was trying to create a concave quarter sphere solid and use the Subtract Solid Tool to round the corners. Like ever CAD software I’ve ever heard of can do. But Shop tells me the quarter sphere object is not a solid. I expose hidden geometry and there is no reason this component isn’t a solid. I tried importing spheres from the 3D warehouse and there were ALL also not solids as well. The follow Me tool can’t make a sphere at the mm scale and drawing one larger then scaling it down still leads to holes in the model and unconnected edges. The circle in a circle with the follow me tool method for making spheres creates an indescribable shape with jagged points and a hole at the top with anything less than a 15 mm radius.
Sketchup just doesn’t support round surfaces well enough. A decade of use and there is still no official sphere tool. The Shop license doesn’t have plugin support. So, I can not use a third party’s work to solve my Sketchup problems that should have been solved by Sketchup long ago. Sketchup is just terrible at mm scale. I’m constantly having to reduce segment for angles when drawing them.
I give up.
