Good morning all,
I’m trying to design up a hand crank wheel that has curved sections cut out of the inside to create the spokes.
I’ve designed it all up on Carbide Create but I’m struggling with getting shapes right to setup the toolpaths. I’ve attached the photo of the object I’m trying to create so I can apply a toolpath.
I can get any of the boolean functions to combine them as I would want. Looking for suggestions. thanks!
A decent amount of duplication of the circles, cut vectors (node edit tool) and trims will allow you to make the fans as a completed shape.
You might also need to verify all the nodes are actually touching, the sample area I grabbed had a small gap. Join vectors can help a lot here.
sample pocket toolpath
Grinder ex.c2d (60 KB)
quickest way I can think of…
Make one, then copy it around using the array tool. To start, delete all the stuff we don’t need
Now create some curves just to make sure the spoke overlaps the circles
Join the curves & the spoke
Subtract the center circle from the spoke, keep the center circle for reference.
Now do a boolean Intersection of the spoke & the outer circle
Circular Array of 5 spokes
Set up your toolpaths as desired
Thank you both! That will work perfectly. I thought I had all my lines intersected on the new version (left side) but I must have missed or shifted one.
Extreme zoom is your friend in Carbide Create. I import a lot of SVGs that are converted in Inkscape from bit map images. There are always small artifacts left that I have to go and delete and move nodes to connect.
Boolean works best with overlapping images. Sometimes you have to do multiple boolean operations to achieve the desired results. Trying to pick all parts of images will give strange results. So simplify and do the boolean one at a time to get your new image.
