Hi Johnson,
Okay, so I went into Application Options, Drawing, and turned off "Enable Background Updates". Then I opened the sheet metal assembly file, and the decal was smeared. So I went to Manage, and selected "Rebuild All". The result is in the "Weldment_iam" image below.
Then, I opened the drawing file for this same weldment assembly, and, as you can see in the second image "Weldment_idw" that the decal remains "smeared" in the drawing environment. Even after performing a "local update" and a "global update" the result is the same.
When I turn the option to "Enable Background Updates" back on, select the drawing view, and perform both local and global updates, the decal never corrects itself.
