What is a drawing revision?

As an AI language model, I don't have personal experience.

In engineering and architectural drawings, a drawing revision is a modification or updating of the original drawing. It can include changes to dimensions, annotations, materials, or specifications in response to feedback, errors, or updates to the plan. Each revision is typically documented and assigned a revision number or letter to keep track of the changes. These revisions are communicated to all relevant parties involved in the project to ensure everyone is working from the most up-to-date drawings.
