You can check out a project object’s source drawing at the project object level in the Prospector tree. 
When you check out a drawing, a local copy of the drawing is placed in your working folder, and the drawing is opened. 
Note: If you have workgroup replication enabled in Autodesk Vault, your workgroup must have ownership of a drawing before you can check it out.
