It gave... --------------------------- Gerber Viewer2.0.1: : gerbv.exe - Application Error --------------------------- The instruction at "0x6b067700" referenced memory at "0x00000000". The memory could not be "read". Click on OK to terminate the program Click on CANCEL to debug the program --------------------------- OK Cancel --------------------------- I am running the most recent version which I had just downloaded, 2.0.1. >Note that the Windows version is experimental, and is not well >tested....

Gerbv tries to guess what your pick/place file looks like, >but it is not omniscient. Yes, I am learning that XYRS is not in any way a standard. Are there any conventions for how to interpret the data? Where is the 0,0 point assumed? What is the 0 degree reference? Which *way* does the rotation go, CW or CCW? I guess you can get the 0,0 reference from the Gerbers, but how does the assembly house translate this to the board? I assume that again, there is no standard. >You can always use a spreadsheet program to reorder and manipulate >your XYRS file if need be. > > > My assembly house is telling me that my XYRS file has the rotations > > backwards, but it seems to me that the reference is arbitrary. > >Interesting..... What sense do they use to define rotations? CW or >CCW? I'm going over there now to discuss this with them. It resulted in my pretty, pretty prototypes being mangled by hand unsoldering and resoldering... :^( I'm off! I'll let you know what I find.
