Good to know
Combine drawing sets reads the drawing name and revision from each file name (C1, C2, P01, P02...), ticks the latest of each, sorts them into drawing-number order and puts a contents page at the front listing drawing, revision and page.
You can untick or tick any drawing before it combines them.
Questions
Is there a limit on the number of files?
No set limit. Large sets depend on your device’s memory; a modern phone or laptop handles a full drawing issue.
Will it keep the quality of my drawings?
Yes. Pages are copied across as they are. Nothing is turned into a picture unless you redact it or choose a smaller file size when saving.
Are my files uploaded?
No. The editor runs in your browser and opens files straight from your device. Nothing is sent to a server, so there is nothing for anyone else to see or keep.
