Necesito poder abrir un archivo de illustrator en una capa determinada

@Felipe306447660l5t the simplest way you could do this is by creating a template. Design your document with the desired layer selected and opened. Save the file and select "Template" from the menu. When you need to start a new document based on this layout, open the template, and it will open on that desired layer that you set-up at first

Hello @Felipe306447660l5t,

Thanks for reaching out. Illustrator currently does not have this functionality. Would you mind creating a UserVoice for this feature request (https://adobe.ly/4e4MDYD) and adding your comments there? Doing this will help us prioritize this request, and you will be notified of any updates.

Feel free to reach out if you have more questions or need assistance. We'd be happy to help.
