Sectioning A Sphere And Extruding Between Sections

Postby 3D Modeling user » Mon Mar 20, 2017 6:29 pm

Basically want to make a tablet shape with 1/4 sphere's at all four corners.

Is it better to start with a rectangular box or start with 4 sphere sections and

fill in or extrude between them?

I would model it in Part Design with polyline. Try the m-key after the first line to toggle between different continuation options.

I don't understand what you want. Do you mean a tablet as in medication or a computer?

Perhaps you could model one 1/4 sphere then Draft Array, purhapes Polar, then Part WB Fuse.

Like a flat tablet.

Rectangular with full radius along edges and those become 1/4 spheres at the corners.

Is it better to start with rectangle and add radiuses or make 1/4 spheres and

fill in between them?

Would have to place 1/4 spheres equally apart at four corners first and

extrude and fill between them.

A rectangular flat box with rounded corners. 1" x 4" x 8".

I guess something like this:

I used Part Box (altered length and width), and then filleted all edges with radius just below thickness of the box.

That's correct .Thank you!

Since we're communicating.

How do I 'flatten' a sphere and extrude between the two halves?

Cut it in half after it's flattened and fill in between halves please?

Flatten a sphere say 1:2 ratio. Half as tall as it is deep or wide.

You have a really odd way of communicating. What you describe is simply not a typical CAD work flow.

You wanted spheres, now you want them "flattened"? Why didn't you say so earlier so the others would not waste time proposing solutions that are obviously not what you wanted? :roll:

Have you not read the answers that were given to you?
