When you are working on a full presentation CMA in Matrix, you can view it at any time by going to the Finish tab:
This can be very helpful because it allows you to see all of the different pages you have selected for your CMA (from the Pages tab). When you view it, the CMA will open up in a PDF format. At that point, you have the option of downloading it to your PC or printing it out. If there are pages you would like to add/remove, simply go to the Pages tab to select new pages or remove existing pages that you do not wish to include in the CMA.
Once you have the CMA presentation completed, you can also email it to your customer from the Finish tab. Just click on Email CMA.
You can also manage your CMA, including viewing or emailing it, by going to My Martix> My CMAs:
