Hi,
Not sure if this is a bug with the gerber viewers but I've made up a design for an Arduino shield using both the sparkfun longpads part, and now the adafruit ARDUINO-BPLACE part and neither of them is rendered as a shield shape by the
Mayhew Labs web viewer. Also, unlike the template for the Dangerous Prototypes Sick-of-Beige, a polygon for GND doesn't get constrained to the shape either in ratsnest view. In each case it's a rectangular board.
Mayhew has a demo gerber to view which is the classic Arduino shield shape, so it is possible.
Rather than rework this another time in trial and error - or send away a design and have it come back a boring rectangle - has anyone used either of those to make a shield that seeed etc cut to the classic shape? If not, what part do you recommend that has the correct shape and dimensions to do this?
Thanks, Geoff
