Advance Part Modeling in Inventor
iParts
Use to create part families that differ by size, material or other variables
If you have stock designs that you use repeatedly, you can create them as iParts. Then you can use the variations, called members, by selecting them from a table. The designs can differ by size, material, mounting configurations, and so on.
Step 1: Create the ipt part close to size needed
Step 2: rename the parameters
Step 3: Manage → Author panel → Create iPart
add parameter, click the Include arrow to add the parameter to the table
each value you select is a column in the iPart table, so include only items that need different values in iPart members

Tabulated Parts or Configuration Tables
Idea is you have a single drawing with dimension variables, then a configuration table along side it, so can have one figure with mulitple configurations. It seems the limited is how many table records can fit on the printed sheet. So if you have an Excel spreadsheet with 100 different customizations and say only 20 records can fit on an 8.5×11 sheet, then will need to create 5 factory iParts.
Individual member files behave like derived parts from the factory part

Derived Parts
Reference existing parts and assemblies as base components that can then be modified.
Think of manually machining a workpiece on a lathe. The original round would be the base component and the modifications who be the different machining steps.

Drawing From Derived Parts
Step 1 - create raw stock say 1“ round, save as Lathe1stProject-01.ipt
Step 2 - create new part, save as Lathe1stProject-02.ipt
Step 3 - Manage → Insert panel - Derive
Step 4 - make edits
Insert each derived part as base drawings
Note,
AutoCAD can insert Base View → From Inventor (cool!!!)

Knurling
Goal is to create a 3D printed part with a knurled surface
Inventor 2019 doesn't have a built in Knurling Tool, have to make them manual, similar to cutting threads. Note a thread profile is the same plane as the longitudinal profile whereas the knurl profile is normal to the coil path.
Step 1 - create the round workpiece
Step 2 - draw the knurl profile, need to extend beyond the end of the knurl
Step 3 - coil
Step 4 - circular pattern copy
Step 5 - mirror
Multi-Body Parts
When working with multi-body parts, need to select the solid body (Solids button). Example
Extrude with New Solid option
Extrude - select Solid body
