In this Inventor iLogic tutorial we will insert a small subassembly (the Hanger Bolt) into the main assembly (the Shaker Table), create a bidirectional information flow between the two with iLogic code, and create an interface that will run the assembly as well as report model information.

This Inventor iLogic tutorial builds on the Shaker Table series of tutorials and picks up after the end of the previous post.

In this Inventor iLogic tutorial the first thing we will be doing is making a few changes in the Designing a Shaker Table with Autodesk Inventor.ipt. The first is to how the dimension that has the Bracket_Offset parameter driving it was placed. I decided to use the Bracket_Offset dimension to drive the model via a dimension, but it will need to be placed a bit different. In the Shaker Table part, double click on the Corner Bracket Sketch to make it active. Make sure you have your dimensions showing expressions (right click > Dimension Properties > Document Settings > Modeling Dimension Display > Show Expression), highlight the one that has Bracket_Offset as an equation, and hit delete. We will place it again, but do so in a way that cannot turn inside-out when driven to zero. To begin with, draw what I refer to as an ‘outrigger’ line starting at the inside corner of the leg and moving towards the outer corner. When you see the Parallel glyph to the centerline of the bracket, click to end the line…
