Form ergonomic hand shapes on handle (sculpting)

Anonymous — Fri, 27 Nov 2020 10:44:12 GMT

Hi Everyone,

hope you are all well during these times. I am facing some difficulty with sculpting a difficult example. I am more versed in designing in the solid environment and recently ventured into sculpting and looked all the Fusion360 tutorials on YouTube (mainly the Fusion 360 official ones) to get a better feel for it.

I however after a few weeks have been stuck on a certain area of the design, namely the thumb grip. I am stuck on how to best tackle this and how to retain the shape of the rest of the yoke while trying to shape the pinch that your thumb would rest on.

I am sure many of you are experts in this area and know a solution to this that I can't see.

Any help is greatly appreciated!

best

Philip

Here a quick mockup of what you can make with surface modeling. I added reference geometry with "plane along path", drew a few splines and rotated smaller body before merging it into whole.

Also, you can literally form this surface with form tool.

you can follow this order if might be easy, in prior get some tutorials if you have

no knowledge about that.

best of luck

I agree with your plan, problem is executing the points to create the right shape. Its alot tricky with keeping G2 form and also form ones hand around a curved and extruded object.

appreciate the reply.

I have had a look at those, there is still a lot missing from the videos as they work a lot in symmetry and basic approaches to adjust the shape.

I think that it should be still done in sculpt mode. I can imagine what was done on the yoke was almost like someone moving clay to form around there thumb, I am trying to mimic that so to keep the G2 curvature.

Product designers often rely on hand drawn sketches when prototyping. When
you understand exactly how shape is built this definitive idea you lack
will take its form. Look at how the 3d sketch is done. Make splines, then
patch surfaces, extrude em, etc.
