Review with other people

Send a drawing out for several people to mark up, then put their marks back together. It all travels as files: nothing is uploaded.

Why you would use it

To collect mark-up from colleagues or consultants on one drawing without a shared server, and to see who changed what before it joins yours.

For example

What to do

1. Send for review: start a round and export the PDF, which carries its project inside. Send that file to each reviewer.
2. A reviewer opens it here, marks it up, and chooses Return my marks, which saves a small file of only their marks to send back.
3. You choose Merge returns, pick the files, check who added, changed or removed what, and Apply. It’s one undo step.

Going further

Each mark is known by its id. A new mark is added once; only the person who made a mark changes or deletes it (a reviewer's change to your marks is left out and listed unless you allow it); if two people changed the same mark the later change wins and the clash is listed; a deleted mark stays deleted unless somebody else changed it since. Merging gives the same result in any order, and merging a file twice changes nothing. Your name comes from Settings and this computer has its own id, made once; no account is involved. A later round keeps the same review, so earlier returns still belong to it.
