I would like to take this opportunity to say something i realized a couple of weeks ago: SU brought back the pleasure i always felt drawing and designing by hand, in the pre-computer days.
i studied architecture in the 70's (yes, in another century, young turks) and people used to say i was a good draftsman. i had real fun drawing with tracing paper, rulers, pencil, china and the like.
my sketches are ok so i developed a design method (for my own use, that is) that consists of going back and forth between free-hand dwgs and the computer, usually vectorworks. an unbalanced method as most of the fun, if not all, was on the free-hand side of it.
not any more. so much so that my partner/wife nags me at times for getting too much into the SU dwgs and forgetting other aspects of the design itself.
i am glad i am not alone in this.
best to all and have fun sketchupping!
