I have a part with two partial cylindrical surfaces and I want to make a datum that is the plane tangent to the two surfaces, as the mating part has a flat surface that is seated up against them.
Part is similar to this example I mocked up:
And I want the datum to be tangent to both surfaces...
Only designing. All fabrication is sourced, and assembly is done through a CM.
This assumes that we are sourcing the complete item from a single supplier. The assembly is quoted and purchased as a single line item and delivered as such.
That does not necessarily mean that supplier will cut...
We design quite a few parts that are welded or riveted parts/permanent assemblies(is there a better name for this?) and I'm wondering how to differentiate between what should be toleranced on the member prints vs. on the end product print.
Ultimately, the end product is what will be inspected...
We've set up PDM to integrate with our drawing revision tables, such that when we set the revision it populates a row in the table with the Rev, date, approver, etc.
The issue is that we set the revision on release, not when the part is put in work. This seems to be the more common practice...
