AutoCAD and ArcGIS capabilities

Hello, and thanks in advance for your time and consideration of my questions!

We are considering purchasing CorelDraw primarily to improve our graphics capabilities, but we also hope to use it to enhance our AutoCAD and ArcGIS output.   The questions are:

1. Can we pull Corel files into CAD and Word, and vice versa?  Is it scalable?

2. How compatible are the Corel files with client and teaming partners that you share information with?  Are you able to send and receive files via email or do they need to be uploaded on an FTP site?

3. Are the file sizes manageable (i.e. are we going to need additional storage to support both CAD and Corel-enhanced drawings?

4. Is CorelDraw able to handle geo-referenced mapping?

Thanks again!
