Parts, assemblies, or sub-assemblies can be used as reference in our models. This means their Bill of Materials structure is set to reference. Reference models are commonly items that we are designing around, and don't want to show up on our manufacturing BOM. These could be supplied by outside sources or modeled up ourselves. These models show up by default as reference lines in an Inventor drawing view. Did you know there are also a number of other options available to control those reference models in the drawing view. Perhaps you want to show them as solid lines, or they keep getting cut off in the drawing view, maybe you don't want to show them at all. It seems like I have been getting a lot of questions about this lately so I thought I would share a deeper look into the referenced model as used in an Inventor drawing.
