I'm trying to add a pattern to get more grip holding a remote controller. Unfortunately the "Pattern" tool in SharkCAD Pro doesn't allow to spread the pattern along a curved surface. The idea is to create a small sphere (2mm diameter), unify it with the main body and then use the Pattern to create the gripped surface. Or to create a pattern of this spheres along the surface and then unify with the main body.
Any suggestion?

The pattern feature only works for holes and recesses, which also need to be spherical or cylindrical, and on spheres, cylinders, and flat surfaces.

Didn't this software have a path array?
Failing that you could always put the surface splines in (array some planes and intersect the surface), add points along a curve (it's a function, or was, where you say how many points and click the curve and it puts them in) then add the spheres to the points

thanks! Hmmm... all too complicated. It would be good to have a tool to spread or fill a curved surface with a objects. any other suggestion how easily and uncomplicated I could add a grip for the handle?

I think that I found an ok solution. Wrap Tool used on array of small circles (here I used 5mm diameter with 10mm center to center spacing) on the surface. Then Explode curve tool on every circle (took some time). Then hide the surface and put a 5mm single point sphere on every exploded circle by using the snap center point button. show the surface again. See attached screendump.
kind regards
Danny

Hi,
I found a solution that is a lot better and faster than the one I suggested above.
1) Use the Points Along Surface Tool
2) Use the Sphere One Point Tool on every point on the surface
See the attached screendump
kind regards
Danny

This seems a similar problem to Art's, here: https://forum.punchcad.c...s&t=10027#post38316, maybe useful.

Thanks for the suggestions! The link is exactly my problem. Would be nice to have a tool to do it ;-)

There could be many different parameters for the distribution of patterns like this, a generic tool that could accommodate all of the possibilities would be interesting to try to create. Moment of Inspiration's got a "flow" tool that drapes a surface over another, but whether or not a regular array would still be satisfyingly visually regular if you draped it over this grip topology is an open question. Another possibility is quad mesh shrink-wrapping or manual painting of a quad mesh (a regular hex mesh would probably be better for circular embossed or debossed features) like retopology tools in some other programs to define their locations. Or some variation on Voronoi distribution. I've used a photo editing program that uses some fractal processing to supposedly extrapolate missing pixels to increase the resolution of images, and that's a feature that's touted in the latest version of Rebelle digital painting app that I'm intending to trial. I'm thinking start with a low-res heightfield of the grip and see what fractal distribution could do from there. Lotsa possibilities...
