Change parameters at point

Recommended Posts

I get weird results when I try to change depths of drill points.  Is this feature locked into using the world CS, rather than what I have selected?  Or am I just doing something wrong?  (usually the case!)

It has been weird since it was changed from the old method to the new method. I have had to make different changes to get exactly what I want.

Good to know it's not just me.  I choose a point, and it seems to take that point, and add the distance from the world CS.  So instead of drilling to -.30, I get a toolpath drilling to 12.453 or whatever.   Goofy.

Yes where I started creating all the points I needed for Change at Point to use. You stating adding values and it gets weird really quick. That said the new advanced drill in 2021 is very nice and allows for a lot of custom things. Might see if that helps you better than Change at Point.

Is 2021 stable enough to rely on at this point?

I have been using it for production work. Several customers have switched to it and are happy.

I had a z depth issue like that and it was because I had an associative clearance height. As soon as I went back to incremental it was fine.

Has this been fixed in 2022 ?

I have used it many a few times in 2022 and seems to be more stable. Need to remember still in incremental and not absolute values when doing change at point. What I don't like is the changes don't show up when you make the toolpath. You can make the changes and they will be accepted, but will not show up when picking the points. You have to finish the toolpath then the changes will show. I wish they showed when the change was made like they will after a toolpath is made. It seems the Database of Mastercam keeps the toolpath in limbo land until it is completed with regards to change at point.

Here is an example file in 2022.

I just had the incentive to install 2022 because of a new job involving a LOT of drillings at different depths, and it seems this bug still exists. You still have to subtract the Z origin of the operation's construction plane from the value you enter to get it right. I assume (rather hope) this is a bug, because if by design, all hope is lost.
