Hi, just wondering how I can edit markups/takeoffs that I made at my home office and view and change at my work office? Any help would be appreciated. Thanks.
Sounds like you would benefit from using a Studio® Project®.

@James Schmidt is right, but you probably only need a Studio Session (not a whole Project). If you're new to Studio Sessions, try my how-to guide to walk you through the process, along with explanations of limitations and best practices.
"Projects" are best when you want to include non-PDF documents.
