This is gold. Thanks for the explanation.

Hello Dean, Thank you for the valuable video lesson. I just wanted a clarification on Profile Position Combines (8:47) topic. Here, for the slot, profile value is larger than the position tolerance (internal feature). For external feature (shaft) is it allowed to give higher value in position than the profile ? I wanted to control the size with the Profile value (0.25) and the boundary with the position at mmc (1.0m). Please advice. Thank you

Hi Dean, If i was trying to control rectangular position of 4 slot widths as a pattern to no datums (just eachother), I could just type 4" x" by the FCF to make them a pattern, however if one of the slot widths was a different width, would it be acceptable to still just type "4x" since the FCF would be attached to a dimension line that didn't fit with the odd slot? or would I have to have 2 FCF - one "3x" and one dimensioned off the other slot width and somehow note a "sim req" to show they are a pattern?

Great explanations. The secret here is "unless you have a cmm that will just figure it out for you". Now a days I feel like the cmm has to figure out the programmer. 😁

Great quote! I forgot I said that, wasn’t in my notes for sure. It’s probably a little glib, because it does take serious skill reason with a CMM machine as you mention. Thanks for watching and commenting.

This is all good info. Thanks for sharing. I do have a question. Do you have any videos explaining position / true position of a feature in relationship to a datum that have Profile callout attached to it. ** Example: on a Nose Tip Fairing type of part, Datum A (flat plane bottom of part) Profile .020 | Datum B (is flange that follows the contour of part 3D feature) no callout attached to it. | Datum C (flat inner wall that is perpendicular to datum A) no callout attached to it. and have a .58x 125 +/-.02 hole with a true position .030 to |A|B|C| with no MMC.** Lets say the holes are too high from datum a about .005 out of tolerance. Can the inspector bestfit the holes and datum a profile to bring them within tolerance ? - CMM / Portable CMM Tech here.

As usual, I learned a lot along your sharing, thank you sir!

Great to hear! Thanks for letting me know.

Do you need to remove datum reference C from the .06 tolerance and remove datum reference B on the .02 tolerance on the first example?

Thank you for what you do here. Btw. nice sound in background. ;) Greetings from Poland.

Thanks so much! Also, I’m glad someone likes the music.
