There is a consistent issue with S3D with object scaling after S3D is restarted. Following are the simple steps to reproduce the issue:
-Import an STL file.
-Scale using the object properties panel (for example 1.5 original size with uniform scaling option set). Object is scaled properly. Closing the properties panel and reopening it will properly show the 1.5 scaling parameter still in effect.
-Exit S3D and restart the program
-Object is reloaded as part of the autosave
-Looking at the object properties it now shows a scale of 1.0 but the dimensions are at the 1.5 size.
-Seeing the scaling of 1.0 (not realizing the bug or intentional 'feature') the user would set the scaling again to 1.5 and wind up with the wrong size object.
I would expect the scaling to show the original parameter (in this case 1.5) after S3D is restarted.
Thank you,
