altiumpcbpcb-designschematics
I have to redo a schematic for a PCB. I have a paper version of the schematic, the Gerber file of the PCB and the PCB in a CADSTAR project but not the schematic. I'm using Altium and wanted to know if there was an easy way to redo the schematic or do I have to do it all by hand?
Ps. the PCB has ~720 component and thats why I'm asking
EDIT
I found a diagram of the PCB made in Zuken's E3.schematic, if it can help me not to do it by hand, let me know.
If I understand your question, that you want to edit the silk screen gerber without changing the original pcb file, yes, it's possible.
You use Altium's included CAM editor (CAMtastic). Stack Exchange won't let me link the manual section because it's a numeric URL, but you can find it easily.
Of course next time you generate the output job (because of a revision, say), you'll have to repeat the editing, so it's usually not the best way to do things.
In the 'Page Setup' at 'Scaling Mode' select 'Scaled Print' (instead of the default 'Fit Document on Page') and then set the Scale to 1.00
Once you've printed it, double check a couple of measurements in different areas of the board in case your printer doesn't scale perfectly enough.

AD in fact DOES have a CADSTAR importer, yet the quality of such imports is always pretty questionable - I wouldn't just import it an then work on that data.
Yet, there are some options to make sure your work matches the original work. We regularly do such work and some proven tasks which may aid you during the way are:
Try to get or create a netlist from the original design (which nets are connected to which pins). When you have finished your design, compare both netlists automatically (you'll need a tool for that). This will make sure that each pin is connected where it should be. The original netlist can probably be generated from within CADSTAR or from Altium's import.
Try to import the PCB and place your parts on the original positions of the design. This will make sure that the design matches the original design. If it's impossible to import the PCB, import the Gerber data and use PnP data to place your parts.
