I’m very new to CNC software…
I have a curved piece, like the letter C and I want to add an angle cut to the inside of the C. Specifically 30 degrees if that matters.(the outside line of the C would be square cut or 90 degrees)
I’ve tried the 3D shape thing and I’m lost. Is there a good way to do this other than using a jigsaw of the cut out piece?
To model a specific angle in Carbide Create Pro one has to either markedly increase the size of the area you are working on, or use a 3D model or pixel image:
Alternately, make a fixture and cut square?
Could you post an image of this?
sorry, should have posted a pic originally. the black is my curved piece and I want to add an angle cut on the inside curve, the grey part is a cross section view. My jigsaw talent is weak and was hoping for CNC precision on that cut.
Dimensions?
Import the pixel image:
Draw the desire geometry:
Adjusting as need be:
Until one arrives at something reasonable:
Done
Recreate the profile:
Done
Done
Use Trim Vectors to trim down to what is wanted:
until one arrives at:
OK
OK
Measure:
The angle is close enough that a 90 degree V tool could be used to cut a 45 degree angle if that deviation from the drawing would be acceptable:
Adjust the thickness:
Duplicate the perimeter in place:
Use Node Editing to remove everything except for the curve which one wishes to cut:
right-click on the ends to access “Cut Vector”
Reselect the right side:
and delete the two extra nodes:
d
d
Done
Assign a “No Offset” Contour to the appropriate depth:
and a Cutout toolpath to the perimeter:
Using a suitably sized tool:
To model this in 3D instead, draw the perimeter at each end:
Make a closed region of (a duplicate of) the geometry by duplicating it in place:
Yes
and slightly shifting and connecting the ends:
Then join everything:
Yes
Then use Offset to get the perimeter of the material which needs to be removed:
Apply
Then model the part:
and subtract it to the scaled depth:
Apply
It will be necessary to slightly overmodel the ends since the depth is greater than the width, so extend as necessary — doing this is left as an exercise for the reader.

WOW!
there is NO way I would have figured that out. That is exactly what I wanted to do. Thank you so much
