Calculator mistake or mine?
Hello,
Ive made a suspension geometry model ( http://racingasp.com/3tdxj10z ) , but when I remade the model in autocad, wheelbase got shorter by 43mm, did i make mistake or geometry calculator has a bug?

Edit. Did some autocad drawing, found out wheel hub offset number is wrong in suspension geometry calculator. Drawing: https://i.imgur.com/iYxJtfP.png

I started by drawing a tire center line by dimension with 2 deg. negative camber (thats a right tire, front view), drawn rest of the tire. At ground level made 15mm positive scrub radius, from scrub radius made a 700mm king pin axis line with 7.2 deg angle. From tire midpoint made a perpendicular 42mm line which represent tire's ET42, from there drew a line backwards to king pin axis, which now is a lengh of hub offset. Measured the last line with annotation - says 86.7mm while in geometry calculator says 114 mm.
