Operation / 3d Contour / Linking / Automatic Depths

[Jobnt]

2020, when doing 3d contours with different z depths using a secondary C and T plate to the WCS, some things I do to the operation, like change stock allowance, break the depths and force everything to the same Z depth at the WCS.

Is this a bug?

Here's a little more context... (I can't upload an MC file, sorry, and I hid some of the geometry to protect proprietary designs).

I didn't create this operation so I'm not sure how it was initially set up, but it does deburring using incremental depths. The Depth is locked to Automatic. It works fine. I was able to re-chain everything, change wall and floor stock settings, top of stock, feed plane etc and no problems.

 

Now when I try to change wall stock from -.025 to -.021 it blows up and the depths all go to WCS Z zero. 

I'm not sure what I changed to make this happen but it's done it on a few different files over the last 6 months. This time the only thing I can think of that I changed was to copy that operation after itself and reselected all the chains and depths and stuff.

It looks like your linking page is set to 2D, not 3D.   When you have 3d contours and choose 2d, your only option is to force everything to an absolute (not automatic) Z depth.  Try changing the Cut Parameters > Contour Type drop down back to 3d.

Oh man, thanks.

How does that keep changing?

No idea?  I haven't seen that, but I haven't really used 2020 in 5 years or so?  Maybe there's a bug or something that's causing it with certain geometry selections?

Maybe a bug with 2D/3D switch, when going into an operation for editing?

I'll keep an eye out for when it changes. Seen it a few times so at least now I'll know what to look for.
