I have the assy dwg, a pin on a shaft follows the slot as an indicator. I know Its a xxxxty way to dimension it. should be a section view with angles. (dwg is from 1985)
That was my first attempt, I did a .28 square normal to the angle and sweep thru the cylinder (hoping to fillet the corners after) but it yellow box errored out.
projected the points onto the cylinder, unrolled at Ø2.875, Create 2 lines tangent, -- ReRoll
The machining part is done, I was just banging my head on the model. I could have sworn I've done this before. like I said I just hit the wall on this.
I could use some ideas to model this feature. Can't seem to figure this one out.
I can unroll geometry to machine it. The programming part is done (axis sub), But modeling it I have hit the wall.
I attached a mcam 2021 file of the problem area.

¿ seems backwards here, what you have circled will break all your lines and arcs to .075 long segments. yet your total tol above seems real high at .025 and will give you an extremely faceted surface.
My default for smooth finish is total tol = .0005 and what you have circled I use a large number like 22.0 (I don't want to break circles, slplines or lines). I also check the "line/arc" box with XY on. (smallers up the code)
I always copy over our old posts into the new version, backing them up as well. then update them. (comparing the output to the previous version.
Always side by side installs!
I never just update the old ones. you could be left out in the cold with no running posts.
I also use Fixed segment length. when using dynamic paths and cutting splines sometimes you can get a series of breaks in a single axis move. this eliminates them quite well.

I'm sure were all aware of how offsetting a line reacts whether your are in 2D or 3D. ( 3D keeps the Z of the existing line while 2D uses the Value in the Z field ), this also worked the same way creating lines using parallel or perpendicular.
That being said. in 2021 "automatically determine Z depth" is available on create line endpoints, and even line perpendicular BUT not on Line Parallel.
Create line Parallel no longer changes depths between 3D or 2D. Seems stuck in 2D mode.
Also make sure the cable is not looped up or crossing any power cables either .
Sometimes people get lazy running cable and loop up the excess at the end or loop it up with other cables.
It forces data to pass near the same point multiple times causing a small magnetic field which can cause data corruption/loss.
