I usually do the file name AND program number prior to posting as a habit. I copy OPs a lot and that does not change the file name.

You can customize the ribbon and add it, it is very basic in 2022 but it is there.

There is a NET-Script folder in Shared that you can use, there should be a few sample scripts in there also.

+1 Above suggestion or 3D HST Blend or Unified(Morph Between 2 Curves) in 3 Axis , Unified(Parallel) in 3 Axis.

100% this! When I teach my multiaxis classes (just did one this morning), I always start with this: Why do you use Multiaxis toolpaths? #1 reason - it looks badass and it makes you look cooler when it comes time for the raise! You paid for the machine, use it all! #2 reason - to avoid hitting the part/machine/fixture. #3 reason - to use the shortest tool possible. I totally agree with Kyle that 90%+ is really just 3+2. And of the remaining 10%, 75% of THAT can be covered with the steps I show in the video above. It's that last 2.5% that can get REeeeeaaaalllll tricky, though Good luck on the interview!

Rough it with optirough, finish with flowline.

+/-.005 Aerospace maybe, but tight tolerance parts expect problems. Need to use probing and a standard monument feature on each part to use to gauging. It could be a tooling ball or a gauge block that will allow you to check something that should never change in size to gauge deviations and then program in a way that compensates when the measurement of them changes.

if you go to file-->config-->toolpath manager you can also set your NC file naming to "last operations nc file name" so that way you don't run into this problem again.

Show up and take a shot at one of the most knowledgeable guys on this forum... doesn't seem like the smartest move to me
