Hello - just started learning Shapr3d and I can’t seem to find a way to calibrate photo or an image that I import and trace? Coming from fusion 360 where its fairly straight forward process, not sure what the best approach to this is in Shapr3d?

Thank you

Measure something in the photo or of the object you used in the photo for a reference and then make a line or box that size in shapr and then resize the image to the line or box matches the measure reference in the photo.
