bad difference (by guy1234)
There's a difference with spheres in the file for some reason. Although the parameters are the same, I'd love to send you a couple of pictures. But unfortunately, I can only attach one file.

I want to say the way you did the translate groups is bad. You've go a semicircle at one end with a distance of 5 from the flat face. Then you translate that into several copies, the last of which is 5.5 from the face.
First observation - if you want to make a sphere from a semi-circle, you MUST use the straight line (diameter) as the axis for the lathe operation. If not, you may not actually get a perfect sphere, or you might get a NURBS failure.
Because all your semicircles are copies, their diameter lines are all parallel. You can not create spheres from all of these with a single lathe operation because each one requires a different point/axis to make a sphere.
To fix this, draw the semi-circle sketch and then perform a LATHE operation (as difference) with just the one sphere. Then do a translate group so each copy will be a copy of the sphere. Solvespace will still make the copies as difference, and you can apply the same constraints to the points to get the 5.5 distance at the other end. Do this for both sides and it should turn out OK.

Thank you for your reply. I did what you just suggested, but how am I supposed to constrain the last sphere? It places the dimension differently than I would like.

The sphere is a 3d group so when step translating is done that is also a 3d group. You may want to constrain the last spheres center point to the workplane of the 2d sketch it came from.
