How do I add texture to a curved face?

[Anonymous]

I am wanting to make a checkered type pattern on the curved face of this handle half... I sketched a triangle on the side of the face and was going to create a sweep over the surface. But to do this I had to draw the angles I wanted the checkering at, then project them onto the curfed face. Now the sweep will work but wont' go all the way off of the handle half since the projected line doesn't continue. Any way for me to do this?

On your first Sketch, Offset the Profile to the outside a smidgen less than the Profile you used to perform the Extrude Cut; Extrude another Body from this Offset Profile to receive your Projected Lines, and use those for your Sweep Path Cut.

Thanks! But wouldn't I want to offset the original sketch by making it larger so the projected lines go all the way off of the curved face? I am not sure I'm following completely. 

I was going for something like this

If you really want a fairly even knurl or waffle pattern on the surface then that is going to be a SLOW:

You'd likely have to create intersection curves or curves projected onto the surface and then use a profile to sweep/cut along that curve.

Have you tried offsetting those faces?   I did- with no success.  Rolled back before the bevels, etc.    But you already had most all the tools built to do the job, so....  

So, all you need is a support for those Lines, right?    If the Profile supporting those Lines matches your part,  the Sweep Cut will follow the same curve, right?   Alternatively, you could use a shallower Profile, resulting in shallower grooves at the edges where a hand might hold the part.    The target of the Sweep need not be the same surface your guide Lines where built on.

The big take-away should be that you build tools in Fusion, not just parts.    Think of it as a machine that builds tools that builds parts- I do, anyway; in that way, you aren't limited to a specific tool set- just your ingenuity.

The result might not be as clean as with native modeling techniques, but it will not slow down your computer that much 😉

Yes I can get the sweep to cut along the projected line, but it ends short of going off of the handle, like this: 

Yes I have come to view fusion like that as well I'm just still a super noob and don't know how to do everything -  but learning is fun! And you guys are very helpful. Thank you!

That's great thank you! This is more of a learning experience for me as well but I may resort to just using CAM to get this done, that's crazy - I had no idea it could do that!

Curse you, screencast.

@Anonymous what technique you are using in the end might have to do what the purpose of this model is. If you ant to render it, then the modeling technique might be different than if you want to actually machine it.

The problem with using the sweep-cut method is - or can be depending on how it's modeled - that it will leave you with a lot of sharp edges that you then would have to manually fillet assuming that a fillet actually succeeds.

The method @lichtzeichenanlage is referencing  would actually work very well for machining as it is basically a machining simulation and would precisely reflect the physical artifact. However, it also leaves you with sharp edges in the model.

@TrippyLighting I never tried it, but the CAM method should work for 3d-pinting, too.
