Thank you so much! I knew it was me..~:?) I find 3d softwarereally intimidating - I've learned to use Sketchup - we bought it to redesign a barn... bt generally they're scary and math heavy. I'm happier modelling in the solid with plastic or wood! Moi is undoubtably the best thing to come down the (3d) road for an old duffer like me. I may actually get the hang of this!
Thanks again - not all forums are so tolerant of raw beginners.
