Help needed with locating pins ASAP

Anonymous

Hi all. In a bit of an urgent need for help. Know what I need to do.... just not how to do it and my google-fu isn't working.

 

I have a mold I need to re-create as is. I have the entire mold created and drawn - except for its location pins.

Here are links to the two parts of the model and both drawings for them (ignore poopiness of drawings - there are some bad parts I'm going to revise - was one of my very first drawings)

In the drawing for BOT B, the two holes not being called out to be tapped
(holes denoted by 2X ∅.2495)
are to be alignment pin location (bottom mold being what they're pressed in to, top mold being the slip fit side)
I believe I should have a single distance dimension and angular dimension between the two holes for them to be properly called out (they should also be GD&T'd... but engineers we contract out for $120K aren't even using GD&T - simply a "press fit" and "slip fit" callout - though I digress...

 

So, if anybody can help me to properly call out those hole locations for alignment pin use, I'd greatly appreciate it.

Looks as if I'm having some trouble with the shared link for the bottom mold drawing, so I'll also include a PDF

Simply attach your files to the thread.  There is no need to use links.  Links are a huge time waster for anyone responding.

Sorry. I thought that the links were the easiest way to download. Should drawings be uploaded as a .DWG?

Angles are exceedingly difficult to measure for inspection.

Should be two linear dimensions from a common datum for location of each hole.

Pdf works fine for drawings.

This is what I had thought, until a mechanical engineer we contracted out told me otherwise... (he also doesn't use GD&T though... say's its useless now...)

(bot b PDF has been added to earlier post - seems as if I can only attach 3 files at once)
