Most of our drawings are in pdf format. Engineering assigns feature ID numbers to individual features. We then in turn bubble the drawings by hand.
Is there a cheap and easy way to apply the bubbles without buying some expensive software? The feature ID numbers can range into the thousands.
I have seen some posts about using excel. I am not sure how this works. I do have access to Mastercam. We don't have models with built in MBD.
Any suggestions??
Thanks!
I feel your pain. As a contract machining company, we often created our own numbering system for the various features of a product on hard copies of customer drawings. I remember hours spent burnishing those little numbers from transfer sheets next to each feature on the drawing, then creating inspection sheets with feature number, criteria, instrument used or to use, and result.
It is ever so essential when dealing with multiple features with the same dimension (0.250 +/-0.005, for example) to prevent confusion or duplication during inspection and assure another inspector can replicate the inspection using similar instruments.
Our system married the feature numbering system with the most efficient order of inspecting these features (required, then listing all the features to be inspected with the same gage or instrument, then next instrument, etc.)
Suggestion:
Typically, the drawings are created in a CAD program, then copied as locked pdf files so they can easily be read or printed without requiring the CAD program be resident on every machine. Is there a possibility of collaborating with the CAD operators to add the feature numbers BEFORE the drawings are copied to pdf?
