Model a texture like a basketball surface?

[evanp4509U4JZ]

Is there a way to apply a "texture" to a models surface? 

I have an injection mold that I would like to apply a texture, like a basketball surface, to specific surfaces of. I need it modeled in so we can machine it into the mold surface using a .030" ball endmill using a parallell path finish path.

So, how do I model the yellow surfaces to be like the dimpling on a basketball?

I was going to suggest the geometric patterning tool, but it is limited to only one face at a time, which makes this unusable  :

[evanp4509U4JZ]

Yes.

This is just part of the mold which will consist of 4 cavities like the one in the model, which is the outer surface or front of the molded part, and 4 instances of the inner or back surface of the molded part which will only have a fine bead blasted finish post machining. The six post like areas need to remain smooth.

Thank you for the help.

Hi! I believe you may want to use Geometric Pattern to do that. Here is an example of strawberry seeds populated on a spline face.

Many thanks!

Thank you. I'll look into the extension.

I've explained the limitations of the Geometric patterning too (in the Design extension) in my post.

Hi  Messrs. TrippyLighting,   Evanp4509U4JZ

How about re-making the critical surfaces into one face? ... by a some kind of loft (or other geometrical continuous surface). 

Mr  Evanp4509U4JZ,  You are Grade 9, so you should have time to learn that it is better not to post design for review/correction in DirectModeling mode.

I the general case even distribution of dimples is close to impossible.  Semi-even, yes, but it would require quite heavy compute for each surface topology.

Dependent upon what sort of mold you are making Mr. Evanp4509U4JZ,  you can experiment with ball bearings covering the critical surface and somehow transferring the resulting pattern into the final part.
