Not difficult to share "good stuff", using Xref and unique CAD standards. Use the eTransmit package routine, to include all associated files.
I receive hundreds of files per year from Engineers, Architects, and Surveyors for construction projects. They follow many different CAD standards. Some of the survey drawings are the worst I've seen. For example, a recent survey DWG sent to me was on SPC. Without using Xref's they copy and pasted the CAD survey within the same Model. Added a border and title block. Also had years of other title blocks, notes, and misc crap scattered within the Model. Not sure which is worse, not using any Xref's or the cad operator binding all Xref's into the model.?ÿ When I request CAD files I tell them to leave it the original CAD state, do NOT explode, translate or save AS. Telling to use eTransmit.
What does your contract say about who owns the "data"?
Here is a standard Acceptance form:
By accepting and utilizing CAD files prepared by Company XYZ, it becomes the users responsibility to verify and confirm that such files are correct and ensure that they conform to all plan requirements.

People share data, it is 2019. Have them sign a release of liability and move on. Most clients around here are putting electronic data into the contract as something they are directly paying for these days too. Again, liability release on electric data... Move on, unless you're worried about what you did.?ÿ
I agree with TNRLS. We live in a digital world today. Define the deliverable in the contract and send it. If you have nothing to hide, why strip data from the CAD file, before sending it to another professional.
I find there are land surveyors that want to keep it close to the chest. Some surveyors will leave no BM's, and no Baseline on the drawings. Not just the CAD file, I'm talking the paper and PDF drawings. Years ago this may have worked to help hold on to the project, forcing developers and contractors to call the original surveyor. Today I see the this as wedge pushing away from the original surveyor, giving us all a black eye. When I contact the original surveyor for this information, they tell me it was NOT called for in the original contract. Which it is B.S. This is an unethical practice of taking advantage of the client in an effort to secure future work.
Lee: this is why a detailed contract is a necessity. If the contract does not specifically recite the obligation to provide the data electronically, then a request to do so after the fact must result in an additional fee. And it is dangerous to release electronic editable data to other than a fellow licensed professional. just my humble opinion 🙂
Practically any project that is big enough to be passed on before it is complete, phased or not, requires Planning Board approval. That means publicly available surveys and construction plans, therefore the control is there for all the world to see. Horizontal control points on the survey and vertical control points on the site plans. Even if that control is stripped from a CAD file it can be reintroduced via actual setback dimension and vertical offsets. Because the info is record on the prior sealed paper drawings the prior professional can be legally liable if you get into extra expense because what you find is not what he said. If there might be an error in your drawings you are better of if another professional finds it before the owner puts it in the ground.

Somewhat similar but not exact to OP's problem:
Asked by general contractor for our RAW data and internal field notes so their project surveyor could re-create our field work.?ÿ We had a contract for a sub on this project not with the GC.?ÿ The project surveyor was trying to cut down on some of their work so the GC put pressure on our client.?ÿ Our client in turn put the screws to us to provide these non-deliverables to the GC's project surveyor.?ÿ We were not cool with this but initially didn't a sound legal reason to not turn over the data.?ÿ Again our contract was not with the GC, it was with the Sub.?ÿ After much thought, we felt the ethical response was to notify the GC that turning over non-deliverable's would trigger an event that would require us to put our insurance on notice that we had been asked for propriety data.?ÿ
This was a honest response and it protected our scope of liability.?ÿ GC realized this was creating more problems then the data was worth and got off the sub's back.?ÿ I realize this was a different problem but maybe it will help in some way....good luck.
"re-create our field work"
Nope, that's never gonna happen unless I'm served a warrant to provide the files or my BOR asks for them.
Appears that most everyone around here has stopped exchanging information and forgot to send out a memo to that effect.
If you have nothing to hide, why strip data from the CAD file, before sending it to another professional.
I don't know about the rest of you, but I make mistakes on occasion while in the field.?ÿ I forget to change an HI, or get an offset direction wrong, or misdescribe something.?ÿ I catch most of these goofs while still in the field and enter a note to change the raw data back in the office, but every once in awhile I don't catch it until drafting the map.?ÿ In those instances I rarely go back and change the raw data, I just correct the map.?ÿ So I never list the survey point file as a deliverable, and I won't release a point file except to another professional with whom I have a good relationship, and when I do I obtain an indemnity agreement first.
Before I share a CAD file I will always change the cursor and background color to be the same. Another useful tip is to set the value of SNAP to be 1000. Then turn on the SNAP and save the drawing file before sharing it.
