Mcam 2021 Chain direction in manager

Hi All,

I tried searching for similar topics which discuss this but had no luck so am posting this in hopes that I'm not the only one who has seen this.  We just updated to 2021 from 2019 and the new Chain Manager is nice, has a couple of functions that weren't in 2019 that make it easier to manipulate chains.  The issue I found is that the "reverse" button doesn't stick.  It reverses the chain when you first select the button but when closing the manager, the chain reverts to the direction it was before "reversing" it.  Then you have to right-click to reverse it again and right-click to change the side to correct the compensation direction.  This doesn't seem to be working correctly.  Am I missing something?

make sure you don't have the reverse inner clicked

Thanks for the reply DUM1.  I looked into the settings and "Reverse inner chains" is not active.  Care to comment crazy^millman instead of just reacting?  🙂  I've been around a while but there are some new tricks this old dog can learn.  LOL

2021 acts completely different than any other version of Mastercam with regards to chaining. I don't really like it and said my peace about it already. The did away with the option to respect last used and in doing so default all chaining to last accepted chaining used. I do solid and wireframe chaining then partial and full and it is a mess what we currently have. Previous version worked so much better. I have not had time to Beta test 2022, but expect more of the same fun with that version when it comes to chaining features. When it is working it is great, but when you need to modify or change something then the fun begins. Solid chaining respects the R for reverse so that finally got resolved after years of asking for it. Still need to train my brain to use O (Previous), J (Adjust) and X (Next) in the solids chaining when using edges. I fumble with Partial in he Solids Chaining process. I like loop and faces through Solid Chaining.  Need to pay close attention to the Bosses or Shared edges when doing this and being doing just edge I can normally make exactly what I want.

crazy^millman I hear you on this.  Solid chaining used to be easy, with the occasional issue of having to reverse the chain.  I could deal with that.  So far in 2021 I'm at a complete loss with solid chaining.  I just use wireframe.  If I can't use the given geometry, I extend (Modify length) wireframe or make new lines/arcs to chain what I need.  Thanks for the response.

All,

 

I figured it out.  It was the "Use cursor position" switch in the Chain manager.  That switch wasn't active so the direction for all closed chains was CCW.  No matter what I did to reverse the direction it would switch it back to make the chain direction CCW for all closed chains.  😲  Once I turned on the "Use cursor position" that annoying reverse chain issue went away.  I had gotten so used to the "Use cursor position" being active by default in previous versions, I forgot what it did when it wasn't active.  Thanks for the responses though DUM1 and crazy^millman.  I hope this helps someone else.
