Hi Oihan
I recently installed an SSL studio in Dorchester, UK (Echotown) and they bought Patchcad. I labelled some stuff on their computer but left before it was cut out and fitted.
I think the template to use on Patchcad is a Mosses and Mitchell 48 way version (assuming you have a 48 wide patchbay). I went back a month later, they had put the labels in place and the horizontal spacing seemed to be fine.
I think the vertical measurement for the SSL clear designation strip is about 6mm high so you need to print one out with the horizontal and vertical measurements and change it to suit. Once you sort it out, you will have the correct template for any future changes on your patchbay, especially outboard stuff which changes all the time of course.
Hope this helps from Jim Lassen.
