You can find some pretty good langauge (examples) for a liability release to share CAD files on the www and maybe talk to your E&O insurance agent. Don't forget to release yourself from liabilty for any software issues, for viruses, attached malware, and you don't gurantee the drawings will work on their system, etc. Note that the drawings are current only to a specific date, that you have no responsibility for notifying them of any changes unless you want to negotiate a fee for that service and you don't gurantee the accuracy of the drawings. (We know the drawings are accurate but its C.Y.A.)
We only share floorplans and RCP (they are in the same file) We strip out all dimensions, ceiling heights, notes, border etc.; we only provide the 'built environment'. Wblock in autocad is a good tool to export a drawing after you have turned off all of the layers you do not want to share.
We'll typically share the floorplan with sprinkler & ductwork subcontractors on a bid project at no cost after they sign a release. Charging an interior designer who is under contract to the owner may be a sticky wicket. Having the interior designer as a future contact, resource, reference or team member and the goodwill toward your client may be worth allowing them to use the file at no cost.

Subject: Sharing dwgs w/interior designer
Before any discussion about providing CAD files I suggest you sit with your client and outline the additional expense they will incur for your time to assemble and prep these files to be shared. This is above the cost (presumably to the interior designer) to actually share. Then there is the additional services (time/cost) to work with such a designer. I have had similar experiences and I have been fortunate enough to been reimbursed by my clients for all of the work to "re-design" projects. The old rule of estimating your projected time then doubling the estimate does not apply, you will need to at least triple your estimate.
This also may not necessarily be a bad thing as this interior designer may be a person you can connect with in the future to pursue more work or share expenses (i.e. professional photo) or this project.
Good luck to all involved.
