Slots are generally handled using contour router bits by the mfg, as opposed to what might be the first thought, ie, many drill hits. Personally, I specify slots using a track/trace-based contour path. Simply place all contour-route passes on a mechanical layer using traces of appropriate width, then identify the layer and routing details in the text file you send to the mfg with the final gerbers, etc. I have heard from others here in this group that they use drill marks at each end of the intended slot, (again, on a mech layer) then specify the slot dimensions, etc to the mfg in their accompanying text file. For creating an oblong pad, I use the rounded rectangle. Unless you really, truly mean that you need a mathematically correct oval (elliptical) pad, best of luck, since that's a real pain-in-the-ass within Protel. It's definitive CAD capabilities are sorely lacking, as evidenced by its crappy "spline", about as useless as the 3D-viewer. Always discuss your need for routes with the board mfg, just as you would discuss any other non-trivial details. If they're worth doing business with, they will provide the most transparent method for communicating these details, and perhaps the easiest method. If not, shop elsewhere. aj
From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Dear sir: I 'm wonderring how to deal with it if a component have unregulation pad&oval via . In making the unregulation pad , I use traces to mimic the shape. and in making oval via(or slot ), I place vias to mimic the shape. Do you have good methods? Thanks for your help. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[EMAIL PROTECTED] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
