I have some parts in an assembly that i got off of the internet. I have them in an assembly and then am making drawings of them, every thing is showing up in the idw. except an outside cover. All the other parts of it are there, what am i missing? is there something to turn on? Im working in inventor 2010

thanks

short answer:
expand the view node in the drawing, right-click on the assembly node and choose "Include All Surfaces"

long answer:
when you downloaded the part files one of them came in as a surface, you can very likely convert it to a solid if needed
