How do I put a finger grip pad on a sphere?
How do I put a finger grip pad on a sphere?
(OP)
Basically I need to put a finger pad or grip on the side a sphere. The ridges that extrude from the sphere are used to grip the part. If anyone can help please help me.






RE: How do I put a finger grip pad on a sphere?
If it's simple parallel ribs around the sphere, then a Revolve would probably be OK.
Other methods could involve creating and thickening surfaces.
If you can post a sketch of what you actually need, we may be able to be more helpful. (See FAQ559-1100)

I'm not sure really how the revolve would work???
I have tried to post the image here

Thanks again for your help.

Any further suggestion would be great.
Thanks....

Note that you can extrude non-planar surfaces into your spherical surfaces to get interesting curves in your grip shapes (the profile of your surface extrusion can be a spline or arc or combination, for instance--however, if you have multiple elements in your extrusion sketch, I recommend you use the Fit Spline feature to create a single sketch entity for a more stable Curve creation for Sweeping.)
At the ends of your grip detail, create a sketch on the flat faces (semi-circle-looking faces). Sketch a circle Coradial to your profile edge there, put a centerline through the circles center, trim to a semi-circle, and revolve the profile 180* to finish off each end.
This ends up consisting of lots of features by the time you're finished, but the results can be exactly what you want (very important in industrial design applications, where you use grip features of this sort all the time). You can also cut in the negative form using this same method.

Create a sketch plane above your sphere. Sketch the shape of your ridges on the sketch plane. Extrude up to surface and select the surface of your spere. Copy your spherical surface and scale it slightly then trim your extrusion to the scaled spherical surface. Hide the sketch plane and the scaled sphere.

One thing I like about the revolved ends is that the centerline doesn't necessarily have to be centered on the arc/circle center--so I can make a longer transition (increased revolve radius). I do this mostly with the negative forms.
