Tracing over a decal - outlines keep shifting!

[HannahStanbury]

Hi.

I imported a decal into Ironcad, created a separate 2D drawing (the same size as the decal) using the extrude shape wizard, and traced over it fairly accurately. I made sure that the Perspective Camera was switched off and used the Look At tool when tracing over the decal at all times.

Whenever I close the document and open it again I keep finding that my outlines have shifted and no longer line up with the decal. Does anyone know what is causing this??

Kind regards

Hannah

It is a good scanner and has a good support.
