Instead of closing it, please move it to the requests section.  Its a feature I'd like to see implemented.

From the pad stacks for the part, what I want should be clear (a plated slot with dimensions shown).  I guess its just a matter of putting it on layer 46 as they require their way.  If I have to do this, I'll just avoid slotted parts until I can get a better tool that does it or I have much more experience with your tools.  I don't want to make a mistake and hose up boards for all our users.

Thanks,  Steve

Well.. can you take your part and make it look how you want it per that description. You're the one that's going to have to ultimately build the board, so complete understanding of what has been done on your part is ideal. Once you get that, I can take what you did to generate the slot and scriptify it into a general solution.

According to the Eagle manual for version 7 section 8.13: 

"8.13 Components with Oblong Holes If the board manufacturer has to mill oblong holes, you have to draw the milling contour of oblong holes in a separate layer. Usually this is layer 46, Milling. The milling contour for components that need oblong holes can be drawn with WIRE (and possibly ARC) with a very fine wire width near or even 0 in the Package Editor. Take a pad that has a drill diameter which lies inside the milling contour, or SMDs, for example in Top and Bottom layer, as basis for the oblong hole. In case of a multilayer board you should draw a WIRE in the used inner layers at the position of the oblong holes so that it covers the milling contour and leaves a kind of restring around the opening. Please inform your board manufacturer that they have to take care on the milling data drawn in this layer.  Also tell  them whether they should  be plated­through or not. Any other cut­outs in the board are drawn in the same way: Use a separate layer, typically layer 46, Milling, and draw the milling contours. Tell your board manufacturer that they have to take care with this information and make special note."

So that is the Eagle way.

As far as I can tell.. there is no way to specify the slots. I'm getting ready to set it so that it'll flag this situation and simply not translate the part(s). Let me know if you come up with a solution and i'll implement it.

I really do not know how best to specify this.  I did not know there would be a fab issue compared to standard drilled holes until this came up.  I spec'd a slot and an oblong pad, and thought it would do the right thing.  Its just one example.  I have other parts with slots.  So I am hoping there is a 'right way' for Eagle that PCBLE can accomodate.

The LBR file shows the slots not coming through.. .just the assembly outlines of the hole. Is this how you want slots done?
