  • I know all three lengths of the sides of a triangle I want to draw. All un-equal with no right angles. How do I draw it in CAD (Rhino, SketchUp or Illustrator) without pissing around with arcs and stuff. There's a few to draw so I need a good work flow.

  • Would knowing the angles help? If so you need to cosine rule to work out the angles from the three lengths.

  • Draw one line, from each end of that line draw circles both with a radius equal to one of the other line. Where the circles intersect is where your two other lines meet. No angular measurements needed.

    I had to do a bunch of these in Fusion360 (all the cool kids are using it) the other day, drawing them was the easy part.
