This tip will show you how to create a substitute level of detail.

• Open an assembly and right-click on Level of Detail under Representations

• Select New Substitute and Derive Assembly

• Select a new file name, location and template; then click OK.

• In the Derive Assembly dialog box, pick the parts you want to include in the substitute. (In this case I’m including everything). Click OK.

• Notice how a new level of detail was created and the assembly is reduced to a single part.  While it's not a big deal with a small assembly, it offers major benefits on an assembly with many parts.

• To switch between levels of detail, right-click and select Activate (or double click on the LOD). You may be prompted to save before switching level of details.
