Hmm... Everyone has a standard for THEIR use of mech layers.
Mech layers are, by default, not specified, for the specific reason that they are open to use by a given tecnician or engineer at the technician or engineer's discretions, aside, of course, from employer mandates... The idea is that they are amorphous, ie, unfixed in their assignment. Otherwise, we would call them "board outline", "PCB documentation 1", "contour route layer", etc. In fact, they were provided for that very reason. Engineers (and technicians) were tired of being told what layers were to be used for what purpose all the time by an EDA vendor, when all they were really doing in the first place was providing a subset of a 2D CAD program, and so we repeatedly requested a group of layers which WE could control to OUR liking. Much like the annoyance that comes about from having proggies like PCAD demand that we choke on their auto-specified ref-designators, having some brain-dead person require our use of layer X to satisfy their concept is intellectually offensive to those of us who have to use our creativity (ie the reason you're not still using tape and mylar). I guess what I'm saying is this...Please don't give the moron management team at Altium another stupid excuse to take control back again. aj >-----Original Message----- >From: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] On Behalf Of Nukien >Sent: Friday, May 19, 2006 11:31 AM >To: Protel EDA Discussion List >Subject: Re: [PEDA] Fwd: 99SE PCB Component gone afar. > >Augh.
