[Br...] Posted 7 hours ago Share Posted 7 hours ago I am a little confused with the FCF stating hole positions from AB and then there is a Basic dimension (119). So how would the best way to get the True Positions of Item #11? This print is referencing ASME 14.5-2009, but I only have the ASME 14.5-2018 Link to comment Share on other sites More sharing options...
[Cl...] Posted 7 hours ago Share Posted 7 hours ago Looks like a sheet metal part. Datum -A- is the top (Plane) of the part? In my opinion unless that 119 centerline is Datum -A-, it got nothing to do with the tp's. Base Alignment - whatever is the largest plane surface for primary (spatial). A 2d line on one edge for planar (Y+) and a point on the front edge for the Y origin and loop it. Measure datum's A & B. Pick up the 11 holes and report XY deviations from basics. Pretty straight forward to me. Link to comment Share on other sites More sharing options...
[Ma...] Posted 7 hours ago Share Posted 7 hours ago That basic 119 is there for other holes. I am curious how you will handle that B(m). It's pattern of top left hole and bottom right hole. Not sure how can Calypso do that. There are 13x dia 6 holes. Link to comment Share on other sites More sharing options...
[Br...] Posted 6 hours ago Author Share Posted 6 hours ago Yes Datum A is the top surface sorry I forgot to mention this. I have always measured holes or TP's from the Feature control frames. Yes it is straight forward and Just an FYI the part is aligned on the top left hole and the bottom right hole as these are marked as Datum B and using the hole straight across to create the planer rotation. I think you both for your visions on the part print and your interpretations, the part is made of aluminum material. Link to comment Share on other sites More sharing options...
