I have Amapi 7 but haven't worked enuff with it to know the full potential. (thanks for the tip). Carrara won't give me the answers I need, but I can extrapolate mathematically, or, in most cases, place a neutral object from point "A" to point "B" and read the virtual size off the object stats and do any scaling, (if needed), from there. Sometimes I wish I was still young enuff to learn as fast as I used to. I'd make better use of some of the apps. on my hard drive. Like to plug myself into the tut's and "Help" files. LOL I appreciate the suggestions and wake-up call on Amapi. Have to use these things mor often.
