X11start Posted August 15, 2021 Share Posted August 15, 2021 Sometimes we think that a drawing is correct, instead we do not realize that the lines that compose it are not perfectly horizontal / vertical or have a length with a dot (not integer). I made this lisp just to find these errors. By selecting the design, the design is recreated and the lines are colored: - Cyan Line Correct rotation and length (whole or half cm) - Green Line Rotation correct but incorrect length (2 or + decim. after dot) - Magenta Line Slightly incorrect rotation (< 1°) and correct length - Red Line Slightly wrong rotation (< 1°) and wrong length - Blue Line Rotation any (visible <> from 0-90-180-270) and length. correct - Yellow Line Rotation any and wrong length As you can see, the door and the left window have wrong lines. The roof has a blue and yellow color as the lines clearly have a rotation greater than 1 °. Verifline.mp4 PS. The design of this house is the project I made .... when I was 4 years old! ;) VERIFLINE.LSP 1 Quote Link to comment Share on other sites More sharing options...
tombu Posted August 15, 2021 Share Posted August 15, 2021 They had CAD when you were four, you're making me feel old! I was in my twenties when CAD first came out. To do survey calculations when I started we had a choice of either a 5 place logarithm book or a 7 place one, either could be interpolated two more places. I didn't think it could ever get better when Texas Instruments first released a calculator with trig functions on it. 1 Quote Link to comment Share on other sites More sharing options...
