Your pictures must be taken on a light panel that meets OSAAP specifications for the scanning process to work correctly.
Our free CAD software requires high quality specific photos in order for the scanning to work correctly.
Each scan has to meet specific requirements in order to be accepted into a design,
see picture below:
More information about this process can be found under the related article "Step #2: Scanning Images Into A Design "
In addition, the frame of the light panel is the datum from which our algorithm scales the parts in the photo to size. If the frame of the light panel is a different size or light intensity from OSAAP's specifications, your images will not scale to the correct size.
