I've used this program a few times in the last couple of years. I'm about to use it again for a DIY DAC I'm finishing. My rear panel has five source jacks: RCA, BNC, USB2, and TOS. I know the size of each and where they are located on the panel. However, I have a tendency to cut things too close and sometimes end up with a file in hand to get a fit. I have data sheets and cut-out diagrams on the AES, RCA, and BNC. The other two I had to measure, both are approximately 10 mm x 10 mm square. Neither of these sockets has any trim available (like a panel nut) to hide mistakes. Question: Is there an engineering standard or common practice for how much to over-size this type of opening. (Like 0.5 mm/side, 1.0 mm/side, etc.
Thanks.
Thanks.
My experience with this is that the cut-outs from FPD are exactly on target.
So if you have the size and location of the actual parts, no need for extra room although for peace of mind you could add say 0.1mm to the hole dimensions, but not to the relative placement!
For the USB2 and TOS I would if I was you try to get a correct dimensioned drawing. They should be available but may need some searching.
If you have a part number you can put in say Mouser, they will normally have a data sheet with dimension drawings available.
And if the drawing says 0.123mm for some dimension, resist the urge to round up!
