Users may experience an issue where applying a decal to an assembly results in a projection of the decal onto the back of the assembly. When applying a decal in the assembly the options to select a face, surface, body, and feature are not available as seen in the image below. Also, for mapping, you will only have the option of projection, spherical, or cylindrical.
To resolve this issue, the user should apply the decal to the part rather than to the assembly. In a part, you can control the faces to which to apply the decal. Also, when applying the decal in the part, you will have the label option for mapping. A label will map the decal onto a model face, similar to adding an adhesive label to a real part.
