While you can export your drawing from the app itself, in order to get all of the associated forms, etc, you will need to go to the ArcSite User Site.
- Within the app, ensure you have uploaded all of the drawings to the ArcSite Cloud account, that you want included in the project download
- Navigate to the ArcSite Cloud site
- Open the Project from list
- In top right corner, click on Download Project link
- Select the objects and formats you want to include
- You will then receive an email with a direct download link of the project
Once you have received the resulting email, you can use the provided link to send to others, so that they can download the work themselves.
