When i send to somebody some things to machine for me i do the following:
/thats how i like to receive also/

- on the 3 D drawing i group all same plate thickness objects at one plane and near each other and send each group as separate file.
The file is accompanied by another JPG snip which shows basic dimensiones, so when you take a glance you could see more or less what the job dimensions are.

-Each piece has detailed snip or even some times 5, with hole detailed explication, where tapped, where pass through, hole clearance, etc.


What i hate to receive is 15 separate files and i waste 2 hours to import them and check dimensions only to give a quote. When they are grouped i could import them at once and could judge material weight, hence price for a minute, not another hour.


if machining 5 parts that go together, i want also to see how they interact, so i always need also the assembly file with them. 99% of the files i have seen or have a design mistake, something not well thought or is done from people who dont have any idea how this will be mounted together in real life.
I have yet to see something that does not need any correction. dealing with fellow DIY crowd i mean.
