Which software can be used to draw lines at exact measurements? I am looking for a tool which could be used for example to draw a top down view of the turning circle for a car. The drawing would consist of the outline of the car, at the correct measurements for the scale. e.g. drawn at 1:100 This type of diagram is getting into CAD software territory, I have tried searching for a tool that would be ideal for this but have not seen any programs that let you draw the linework freely while being able to specify line lengths, or use tools to ensure that lines are of exact length / scale Sketchup Layout is the closest tool I have seen, but it seems to be aimed at drawing architecture and I'm not sure if it is suitable for drawing any linework at known measurements. Aside from this the only other methods I have seen to achieve this is using grid guides / snapping in Illustrator / gimp / inkscape which is better than nothing, but not really ideal Thanks
