Have you broken the alignment of the part, with the mother piece? It thus becomes completely independent and you can modify it as you wish without affecting the other parts (wireframe, edge, shadow etc ... )
"You might need to pre-select the components that are in a different position in the Alternate View (use the feature tree or the graphic area) and move them to a new layer."
'You need to preselect the component that is in the other position view (use the tree or graphics area) and move it to a new layer"
The second says:
"I have selected a sub assembly from the feature tree and used "component line font" and changed the layer. It works! but the bug you metioned comes into play"
"I selected a subassembly from the arb and used "Component Line Font" and changed the layer. It works, but the graphic bug you mentioned appears": the room goes shaded, so it doesn't work!
There's also if you're in SW2014, the ability to convert the view in another position to a sketch block and there you'll have your block in the selected layer and you can manage your colors and stroke type.
Another solution is to put the view in another layer (right click from the feature manager).
Then hide one of the components of this view (always right click in the feature manager), there a recalculation is created and all the strokes of the view are recalculated and pass into the color and type of stroke of the layer.
