SOLIDWORKS Design & Help

Does SolidWorks do Booleans?  If so, you could take 6 spheres and Boolean them to get the common mass.

Same would work for the triangle made up of 4 spheres (or 5 spheres for a pyramid)

that is my technique in SolidWork and it's a solid cube.

And this for pyramid

@Kasidaje P. could you do step by step? I think I'm doing half of the work.

I think the "triangle" one Kasidaje posted could be considered a Reuleaux Tetrahedron. I'm not sure if other shapes like a cube follow along with the same naming system.

They do, Fred.

I've posted a both a Reuleaux Tetrahedron and a Reuleaux Dodecahedron.

The method I used was to draw a 3D sketch of the shape, draw a semi-circle on each vertex, then revolve all the semi-circles (without merging the bodies).

Then I used the "Combine" command and chose "Common".

That's all.

Both the previous models still have the FeatureManager design tree, so you could easily see what I've done.

The only thing you've got to put into consideration is that all the semi-circles must have the same radius, and that radius is a factor that affects the final shape (the other is the side length of the 3D polyhedron).

Hi bros. Now I uploaded that model in ".SLDPRT" you can download it for seeing step by step. link is below...

Reuleaux

I think, one extrude and 2 cut revolve should be the best way. Patterns might take more regeneration time.

Thanks a lot for your help. I did one surface and used a pattern and then stitched it together. Your methods are faster.

@Kasidaje. @Yahya thanks a lot. I was looking for the mathematical name.

Reuleaux shapes it is!

They are also called "Solids of constant width", check this article.

Yahya suggested a similar solution to my previous suggestion; the "Booleans" I was referring to are called "Combine Features" in SolidWorks, and "Common" is the type to be used for this project.  (I'm still learning)
