MarkSphere — drawing markup
Drawing Markup Software for AEC Project Teams
Review and mark up project drawings together in one connected workspace. MarkSphere is built for AEC drawing review — plan sets with dimensions, details, and field conditions — not generic document review. Every annotation is attributed and the drawings stay connected to the project.
Built for plan sets, not generic documents
AEC drawings carry plans, details, dimensions, engineering information, and field conditions. MarkSphere treats drawing review as its own discipline — collaborative, attributed, and tied to the project.
Review together, attributed, in the browser
Upload PDF plan sets and mark them up on the sheet with no CAD seat or PDF license. Teammates review the same sheet at once, every annotation carries its author and timestamp, and downloads can be marked or clean.

Because MarkSphere links to ProjectSphere, the marked-up drawings stay part of the project record rather than living as loose files in an inbox.
Drawing markup questions
- How is this different from generic PDF or document review?
- MarkSphere is built for AEC drawing review — plan sets with dimensions, details, and field conditions — rather than generic office documents. Drawings live in a shared, attributed workspace connected to the project instead of a general-purpose PDF commenter.
- Do we need CAD or a PDF license to review drawings?
- No. MarkSphere runs in the browser. Upload PDF drawings and mark them up directly on the sheet — no desktop CAD seat or separate PDF license required to review.
- Can several people mark up the same drawing at once?
- Yes. Teammates mark up the same sheet at the same time, and every annotation carries its author and timestamp, so review stays one attributed conversation.
