I've just used WinPCD to find the relative center of two drivers using the three measurement technique.
Now that I've entered the x,y,z data and have found the relative center how do I transfer this info into another x-over designer like SW or SE? For example SpeakerWorkshop only has input for entering the z (woofer acoustic center.) Since I can't enter the vertical off-set in SW will that throw the z info off?
Am I forced to use WinPCD for x-over sims if I use this method to find the relative center? What am I missing?
Importing found data into another x-over designer?

Oh..and btw, all of my measurements are extracted to minimum with no flight info.

I gave up on SpeakerWorkshop back in 97-98, though I was primarily interested in measuring with it. I bought LAUD and still use that as my primary measurement system. I never got far with the crossover design part.
If SpeakerWorkshop only allows for a z-offset, what you will have to do is to set the x and y values to zero in WinPCD and then set the z-offset. I'm a bit surprised, because I can't see any use for having only a z-offset unless you the user is not able to acquire SPL files with measured phase. There's no issue with having M-P files.
There is a separate benefit with the three measurement technique. It's possible to create an accurate model of drivers in 3-D space without measured phase if measured SPL is available. This does require that the phase can be generated.
One key point is that you _must_ use the same driver SPL files. Any alteration of these files (or different files) will in all likelihood introduce error. No change in the driver highpass/lowpass should be made once you have determined the offset. This is true for any program, including WinPCD.
