[Ma...] Posted January 24 Share Posted January 24 Hello. I have a question about the notation in the drawing. What is your opinion on the interpretation of the entry in the attached view? Base "A" is the plane, base "B" and "C" are marked circles. As for the 0.25M ABC rating, it's clear, I assess each circle separately, but how to assess the 0.1A record? You understand this by the position of the pattern of holes 1,2,3 or perhaps by the perpendicularity of these elements (the material is 5 mm thick).

[Ma...] Posted January 24 Share Posted January 24 I am wondering how is tolerated "C" hole since it's obvious that 1,2,3 and C are making pattern/or should be reported as whole. Otherwise it would be 4 x position callout for each hole. Any comments on that? Link to comment Share on other sites More sharing options...

[ni...] Posted January 24 Share Posted January 24 Hi, they are located from the others For me you have to do with the three diameters a best fit with rotation and translation alowed Link to comment Share on other sites More sharing options...
[ni...] Posted January 25 Share Posted January 25 Found on ISO 5458, for non french people, the coted interpretation is below. Link to comment Share on other sites More sharing options...
[Da...] Posted January 25 Share Posted January 25 Please sign in to view this quote. You are right with ISO 5458:1998, my bad I didn't asked OP all the details. I was assuming using ISO 5458:2018 version, where this would be Separate Zones. Link to comment Share on other sites More sharing options...

[Ma...] Posted February 6 Share Posted February 6 Please sign in to view this quote. He meant bore pattern where you can use translation and rotation bestfit. Link to comment Share on other sites More sharing options...
[Jo...] Posted February 7 Share Posted February 7 Please sign in to view this quote. I know, but when I use position, select bore pattern, select elements - three circles and tick rotation/translation, then I wil not get positions to reference system ABC right... I mean when I drill the whole three holes pattern 1mm from its nominal ABC position and tick rotation/translation, then still have beautifuly green results, but that is not what I want in this case right? Just asking... Link to comment Share on other sites More sharing options...
[Ma...] Posted February 7 Share Posted February 7 Well if you want to report to fully restrained alignment ( ABC ) then you can not use translation rotation. Only if you have it without bases or drawing says something different Link to comment Share on other sites More sharing options...
