Drawings are where engineering actually happens. The Studios bring markup, CAD and comparison into the same workspace as everything else — no desktop licences, no exports.
This is the PDF Studio mid-review: a revision cloud around the pumps whose plinths must move, callouts tied to the open RFIs, and a FOR REVIEW stamp — all on the live sheet, listed in the markups rail, saved into the project record.


Comments carry their references — “Relocate CHWP-01/02 plinths 200 mm east — access clearance per RFI-0492” — so the drawing conversation and the register stay one story.
Both studios share the workspace's file browsing: the project library, your OneDrive, your mail attachments, or a file from this computer. CAD Studio opens DWG/DXF directly in the browser.


The compare engine overlays two revisions and paints the differences — removed in red, added in teal — and runs automatically when a new revision is submitted on a workflow.
Every markup and drawing capability, named.
"The markup suite" is the well-known per-seat PDF application; "the construction cloud" is the big per-user-per-month platform. Both excellent at what they chose — the difference here is one integrated record, on your own server.
