Wrapped Cut Issue

Kevin Paris Jan 10, 2019 3:04 PM

Hi guys,

I'm attempting to reduce the thickness of the spokes circled in blue:

The intent is to make them slightly less thick than the other spokes purely for visual effect, so I'd like to cut about 5mm deep from the face. My first instinct was to wrap a sketch to the face of the wheel, then cut the desired amount. However, when I did that, here was the result:

As you can see, it's a mess. What's the best approach to get the results I want? Attached is the file in question. Thank you in advance!

Use your sketch to create split lines, offset the inside face to the desired amount and use it to cut with or up to. You could potentially use the move face command as well after creating split lines. I would also suggest cutting the wheel into a portion and then patterning it back once you get the desired result.

  Did the split lines, using the move face command worked for part of it but not all of it (there's other sections I'm "thinning", but for the sake of simplicity I highlighted the one area when asking the question). I am confused with the "offset the inside face" solution you mentioned. After I split the lines, I used the Offset Surface tool and this was the result:
  
  As you can see, the surface protrudes from the side of the spoke. Am I missing something? I attached the updated file in case you'd like to poke around.

    You would use the surface to either do a "cut with surface" or use it as an end condition (up to surface) for a normal cut from the top face.

Kevin, unfortunately it's a "future Version" for me so I can't verify this but the wheel does not appear to have any draft/taper in the area you wish to modify so it should be pretty straight forward.

I'm thinking that you make a sketch within the section you highlighted offsetting entities as needed leaving you thinner spokes. Once you're happy with the "look" simply do a circular pattern of the cut-extrude around the wheel.

..focus on 1/2 of the 1/5 spoke and offset/mirror/pattern..?

  Basically create a plane (top edge of your rim).
  Start a sketch on that plane.
  Select the 5 edges that represent the perimeter of one spoke you wish to cut back and convert those edges.
  Drag the ends of the lines so they over lap, add a line across the open gap and trim all the lines to form a closed polygon.(see below)
  Extrude "Offset from surface" picking the main surface of the rim and using a distance of 5mm. (you might have to adjust the direction of offset)
  Create an axis using Right and Front planes.
  Create a circular pattern using the axis, your previous extrude cut and an instance count of 5.

    Sorry. Extrude-cut "Offset from surface" my bad.

      Doh! Don't know how I missed the offset from surface option before. Thanks!
