Backing up a bit. What was done in the few seconds prior to this error?

As long as Mastercam corrects the calculation result to the correct value.... Mastercam will be faster than SW NX Catia... If arc tangent-arc dynamics.... Adding a tangent option can handle this type of graphics more efficiently

When using Surface Finish Contour, the tool must be able to undercut for the undercut option to be enabled. You may not have selected the tool correctly.... Using Unified should be a better way...

I tried this 3 times and got 3 different answers, none of which were correct. Parametric modelers, Catia, SolidWorks and NX all got the same answer as did Jake's old school geometry solution.

I can't get anything to work correctly they want to cut straight down ignoring the undercut .

But the distance from the intersection to the tangent point have to be equal for both lines, always. We've got that for the angled line, it's all that's needed. Jake: A "tangent - 2 entities - thru point" type option would save you a few clicks, but your doing it right geometry wise with the "line bisect" method.

try it with a 6 MB program. Ours would stop half way thru with a 2 GB card.

Unified toolpaths can be locked to 3 axis on the Tool Axis Control page and posted out and run on 3 axis machines

It's being done on a 3-axis machine not sure that would work.

Maybe high speed water line with the tilt tool collision checking option enabled enabled??? This could be done with a Module Works Unified toolpath as well

Using the SFC it did not follow the surfaces and actually do the undercut it just cut straight down. and the detect undercuts is greyed out.

You may have to play with the .stl export tolerance a bit to get a good clean model out. I brought them into Magics RP and it also shows open edges and it won't repair them...not all of them anyway.

yes I can share

Way back in ancient times in my high school drafting class we solved hundreds of geometric problems like this, using a T-square, scale, protractor and a compass. At the time I wondered what the point was, yet 53 years later, here we are. My old drafting teacher was a strict taskmaster and would be supremely disappointed in me for forgetting the ancient ways.

Flowline and Surface Finish Contour both support undercutting. Can you share a file?

I am working on a punch for a trim die, it has undercut surfaces below the trim edge, is there a program I can do this with using a lolipop style cutter? i had done it years ago before they had these high speed toolpaths but for the life of me cannot remember which one it was or if they moved it.

I think I understand that it is a mixture of C# and C++. is it like that? Can Windows Forms be added to it? How can I start them? thanks for your help

Every day is a school day!!!!

It's likely related to setup sheets that use a pdf reader, Here is a link to a thread on adobe about solving this, Solved: Acromissingcompwclass: AcroRD32.exe Application er... - Adobe Community - 8849028 You could also try changing the default program for opening pdfs

Thought #1 are you running One Drive on this PC? Thought #2 Both of these errors are Adobe Acrobat errors It's pretty weird they should be popping up during a Mastercam session Do you have Acrobat open??

I have been getting these and other Application Errors while in Mastercam, at this point no other programs are getting these. It shuts me down when they pop up. Any idea what may be causing this? I did reach out to our reseller and they are not familiar with them. It's pretty frustrating and I am hoping this is not an underlying issue that could wind up being pretty bad. I searched the internet but I'm not real certain what I am looking at, I'm not a applicationscomputer guy by any means Thanks in advance for any input.

Thanks Colin! I actually did stumble on the goldmine of youtube videos you have posted there, and let me just say thank you for putting that info out there. I haven't made it through all the content yet, but the videos I watched so far were super helpful. I will also try to start assigning my work offsets by plane. I haven't tried that before, but I like that it might make things a little more foolproof.

I tried adding all three values (XY & Z) on the G43.4 line but got weird undesired motion. I tried your second suggestion of using G43 inside the G68.2 call and that seemed to work. I tried it without changing the 5006 parameter and didn't get any Z motion with the G49. Is this the parameter I should change?

Sorry, misinterpretation on my end. You weren't finding an issue with the original question, you were providing a more in depth explanation to the provided solution. Thank you sir, this is much appreciated.

Just move the box down a little on that page. edit: it is a bit of a PITA
