Spanki (and Xena), thanks for the clarification. All I can say is that so far I've been able to do everything I wanted to do with magnets without ever touching the base. I daresay that you could set me a modelling challenge that I wouldn't be able to accomplish without adjusting the base; but so far I haven't wanted to do whatever that would be. Maybe I'm just not very demanding. :) However for me, it was realising that I didn't have to fiddle with positioning the base that enabled me to make the leap from magnetophobe to magnetophile. I also use magnets routinely as part of my modelling workflow. My (admittedly free and probably less versatile) modeller scales the selection and doesn't scale the rest, and it's well worth an extra export / import step to get the advantage of those fall-off zones.
