[PEDA] irregular shaped holes ??
hello, i've never had to place an irregular shaped hole in a board before, and i can't figure out how to do it. i looked up drill, hole, and irregular in the help and had no luck. its essentially an elongated circle. i kinda figure that it involves perhaps placing some lines and arcs on a specific mechanical layer, but thats as far as i can get. all the holes i have placed so far have been done with the pad tool. i notice that you can adjust the shape of the solder ring using this tool, but not the hole shape itself. thank you, miker * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * - or email - * mailto:[EMAIL PROTECTED]?body=leave%20proteledaforum * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

If you include Mech4 on the gerbers for the copper layers that should work.

It is basically what I do. I would typically dimension and add start and end coords of the slot (on a different mech layer). The PCB maker has to interpret what the details on the Mech layers mean. If you add appropriate strings and coords and dimension you can easily make it clear what is required. Basically there is no method, in Protel at least, to convey any sort of slot. You basically use the non-electrical (usually mech or drill drw layers) to specify the slot and then add info in manufacturing details. If it is complex you then ring the PCB maker to make sure the understand exactly. I have done one board with a mix of complex outline routes, large routed holes, routed slots and a few controlled depth routs (not right through the PCB). I used a series of hatch patterns to discriminate full depth routs from the controlled-z routs and labelled it all on a different mech layer. Board came through without fault. I have never had a slot routing error. BTW - Mike, either you are not doing many PCBs or you are much more comfortable with Protel and PCB manufacture in general. I recall you thinking not so long ago, when you started in this game, that it was all a bit of a nightmare. Congratulations.
