a scale starting point

[SteinHDan]

I typically try to find a couple of measurements from a spec sheet, and then scale a photo or diagram as a canvas in fusion 360 to match the known sizes.

E.g. from the spec sheet of the CAT 390F excavator, I can see that the length from the center to the very back is X meters, and the height from the ground up to the counterweight is Y meters. I insert the canvas and then scale it to match the known measurements.

After the canvas has been scaled properly, I can draw on top of it to match the sizes:


Insert canvas:






Switch to orthograpic view:





Draw in the objects:




Switch back to perspective view:




Hide canvas:





Best regards,
Stein :-)
