I have to make a cad drawing of chair , but first I have to measure the chair and put the dimension in the drawing , but there are lot of curved shapes on the chair and lot of angle , but I couldn't figure out how to measure those curves and angles.Should I lie the chair down and sketch it on the surface and measure it from the surface. Thanks
When I first saw this question, I was going to make a snappy answer such as - randomly draw lines all over the place and then erase all the ones that don't look like a chair. But, after reading the question, it's a good one. Measuring curves can be very tricky. I usually draw a straight line parallel to the curves on the actual object and mark the line at several preset, equally spaced points. I then make several measurements at these set intervals on the line to the actual curves - the more measurements, the more accurate the drawing. I then use this information to duplicate the curve from a straight line in the drawing. There may be other methods, too, but I find that this one works best for me. Good luck.
