Before I go off and code something I'd like some feedback. I'm thinking that perhaps each layer gets a type that is user configurable. Types would be: copper silk soldermask relief solderpaste outline - as in the outline of the finished board route - as in cutting slots with a routing bit assembly - like an assembly drawing, fab drawing, etc other - not sure what else goes here but this would be a catch all plated drill unplated drill Once this is set, there are some additional attributes that some of these may have. For copper layers, we need the stackup order. Do we want to associate this with a particular layer and keep it when you move them up and down in the visual display? i.e. allow someone to display layer 1, layer4, layer 3, layer2 in that order? Or do we automatically assign the stackup based on how they are visually? If the stackup is not constrained by layer ordering then I think we probably want to display the stackup order or it may get too out of sync. For drill layers, we need a top and bottom layer that the drill goes to. For example on a 16 layer board, you might have a 9-12 drill file and a 1-16 drill file, etc. Here I don't really see any other option than to have two fields that must be user edited. One is for top layer where the values can be symbolic "top" or numeric 1,2,3,4, etc and the other for bottom layer where the choices are "bot" or numeric, 4,3,2, etc. The defaults would be "top" and "bot" respectively since the majority of designs probably do not make use of multiple drill files like this. -Dan ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
