It is important to clarify the ownership of drawings your company produces.
Make sure the contract or agreements clarify the ownership of drawings and documents.
Some clients may expect the drawings or designs to be their property once a project is delivered. If your company’s drawings or designs are proprietary or are designs you use on other projects you will need to state that your company keeps the ownership in the contract.
If you don’t have this in the contract, it can make a difficult sticking point with the client at a later stage in the project.
