Hello people, i come to help, i need to print my pcb but i don't want to buy a pcb in the page
i want to make my orwner pcb for ironing method.
Is there a way to export my badge to pdf with the actual dimensions to be able to make my own badge?
Thank you for your time!
excuse me for my english

@andyfierman I already did the whole procedure but the drilling circles do not appear in the pdc

Please post some images of the output you do get and make your project public.

You can drag and drop images directly into forum posts.

You have two incomplete nets:

OK, the Tutorial needs to be updated.

This is how you can set up the Export tool:

Then the pdf looks like this:

Sorry: you need to select the Mirror options to reverse the image for a contact print:

Hey, here are the settings you should use:

With these settings your PDF will look like this:

BUT, to save you a lot of time and sanity, I would suggest that you reroute that board. I have done quite a few toner transfer home etched PCB's and I would not attempt this board as it is now.
You haven't set yourself up for success. The traces are way too close and some go through too narrow spaces that I can pretty much guarantee there will be unetched or overetched spots.
By the routing I also notice that you are using the autorouter. This is actually a good practice board to route by hand and learn component placement.
If you try, the board can be a bit smaller as well, but the LED's are the main point here, so not a lot smaller.
You have such a large board, the traces can easily be much more apart from each other.
Also, have the 5V traces at least 20mil (0.5 mm) as it will help with the etching. Sometimes the 10mil traces eat away.
Rotate some of your resistors so traces from and to each of them don't need to go around Africa and back.
Look how I placed the resistors R26 - R29.
Place and rotate them so traces don't have to be long from each point to the next one.
Try to rotate the IC's too, maybe that will make the routing easier.

See how the ratsnest wires don't cross as much next to U4 as the cross for U3?
Good component placemnt helps a lot too.

Don't let the autorouter route your GND, leave it as a copper area for the end.
You're going to have a better chance at etching the board and waste a ton less etchant and the process itself is going to take a lot faster due to not having to eat all that copper.

Also, I noticed your schematic has 5V but no GND. Add it in your schematic and update the PCB. That will let you add the desing rule for the autorouter to not route the GND net.

I hope this helps you and I want you to succeed and learn something along the way! :)
