    Multple single segment position

    Thank you for you thoughts and insights. I have concluded that changing the lower row to perpendicularity is the logical thing and communicates the desired control.

    Multple single segment position

    Company standard, also it is locked in the Catia dwg standard file. I can not change that and I'm not going the extra mile to manually change them all the time. So to say, both controls are correct. Because B is also an axis, having the 90° BSC angle to B controls the orientaion. But if I'm...

    Multple single segment position

    Hello there! I've got a ball here for discussion. The ball is constrained between seating elements and is rotated around Datum A by the slot on top. My coworker made the decision to give that slot two different position tolerances. His idea: 0.08 concentricity to A because the offset isn't that...

    ISO 8062 and ISO 2768 for one dimension

    Send back to the engineer who let out an incomplete part definition for PPAP to solve their problem.

    Gap in a feature of size

    Personal feelings and opinions are ignored when we talk about functioning parts and their evaluation. The same goes to your nitpicky QA team.

    composite tolerance at lmc : is it nonsense?

    Our Compressor department frequently uses LMC on cast aluminium parts where minimum wall thicknesses are needed. Other than that, I don't know much practical use for LMC. Can't gauge it, hard to comprehend to most engineers. It wasn't even taught in our school too. Btw I see "Composite" in the...

    trigger catia

    Just use the built in Save Management. I don't see a point of having a window saying "Hey look, I'm saving your document, how awesome am I!"

    Diameter tolerance over a short length

    I'd make a note with an arroW pointing to the area: "YOU MUST KEEP TIGHT TOLERANCE ONLY HERE! IGNORE THE REST! BEST OF LUCK: DESIGNER"

    Profil tolerance check (Unequally Disposed Tolerance)

    I have trouble understanding the F-G, H-I profile definition under the FCF. What I know is that either the all around circle or a "between" or "from-to" arrow can be used. However this "common datum" style designator is confusing to me. And the features being controlled are edges, and a radius...

    CATIA v5 DRAFTING

    I have sent you a message, did you receive it? I can't post it here because it's too long.

    CATIA v5 DRAFTING

    I have a macro for that which replaces drawing links. I encounter refusal a lot so we always use the macro.

    Square drive socket - loosening prevention

    Sorry for the confusion. I meant perpendicular, not parallel. I mean this banana.

    Square drive socket - loosening prevention

    The "ball groove" that runs parallel to the cylinder axis. I'm guessing it's either an internal grooving tool or might be a spherical undercut mill. I was wondering which one would lead to cheaper parts and overall better performance.

    Square drive socket - loosening prevention

    Hi there! I'm wondering how they are manufacturing the groove inside the square socket of hand tools? I'm familiar with the through hole versions and their dimensions (https://www.engineersedge.com/hardware/square-drive-tools.htm), but I haven't found anything on the groove sizes and methods...

    Pedigree in a Part Number?

    Running products aren't updated automatically, different versions are used parallelly. The dwg carries the revision notes, and it's stated in the title block that a 'number up' is a revision or a version up. Like the picture.
