Dear TinkerCad Users,

Please help a newbie.

How to create a 3/8" hole through the center of a half-sphere?

I can create a half-sphere.

I can create a hole in it.

I cannot set the dimensions of the hole to 3/8" there.

How can it be done.

Please advise.

Thanks.

  1) Make a half-sphere
  2) Make a cylinder that is 3/8 x 3/8 x tall enough to clear your half sphere

  3) Set cylinder to hole type

  4) Select the cylinder and the half sphere
  5) Use the align tool (is on the right side of the toolbar up top)

  6) Click the center X-axis align node 
  7) click the center Y-axis align node
  8) Group
