Lucky for me, I can do just fine modelling my home with a shoebox, and it’s almost to scale!
ETA: on a serious note, I went to the product website, just to see if they had it for windows (they do) and noticed that the regular version for Windows is $9.99, pro version in $19.99, and was like, are they marking this up for the BB store? Then I clicked on the mac version and it’s regular version $29.99, pro version $69.99 WTF? is the software itself appreciably different or is there just a Mac tax on software?
