It isn´t Sketch-up!!
Last sunday I posted a thread but I don't know what happened with it. Anyway, here it is again.
My wife asked to change a sink in on of the bathrooms so I took and old one I had in the laundry room to make a corner cabinet for a new vanity.
Using the garage floor as a blackboard I traced two perpendicular axis and put the Oakbrook sink upside down to mark all its perimeter and get the estimated dimensions for the new cabinet. The design stage is over without Sketch-up.
We, woodworkers are everywhere!!!
