When using iLogic our imagination is one of the few limits of the functionality. Today I take a look at using select case in a very simple fashion. You can use these same ideas to test multiple variations within your design. The case structure lets you choose between more than two alternatives. Let’s take a look at my example.

I am going to take a look at writing a rule within iLogic that is going to allow me to control minimum and maxium values for a given parameter. The best part is I can take advantage of the rules wizard found within iLogic to basically write the rule for me.
Let’s take a look:

This feature was new to Inventor 2010 and with the next release on the way, I wanted to get this one in our blog. User Coordinate Systems in Inventor. I have found many interesting ways to implement this for customers over the year. In a single part you can use this to locate a new 0X,0Y,0Z, or just locate a specific connection point. Then in the assembly this works great for constraining parts together based on that known point instead of using three or more assembly constraints. This can be done easily using the Constraint Set constraint in the assembly environment. It allows you to quickly put components together based on mating UCS axis, and planes in a few clicks.

One of the foreign concepts to many people new to FEA is the idea of “Convergence”. Convergence is an analytical method that many analysts use to determine the quality of their FEA results. Since FEA uses small elements to solve complex problems, a larger number of smaller elements can sometimes yield more accurate results. But how small is small enough when it comes to element sizes? This is where convergence comes into play. Convergence in Inventor Simulation is actually a series of settings that can be used to automatically make mesh elements smaller, and help determine if results are accurate.
The basic concept is that the mesh will automatically be made of smaller elements and solved until the results of the refined mesh fall within a percentage of the previous mesh. In other words: The smaller mesh is no longer significantly changing the results, and it making it smaller would yield diminishing returns.
In the image below, convergence settings were used to determine the validity of the FEA results. Before using convergence, the stress in the model was calculated to be 5.85 ksi. After turning on convergence (which refines the mesh and makes it smaller), the stress was calculated to be 6.205ksi with only .448% defiation from the previous iteration. This shows us that we can trust our FEA setup and gives us more confidence in our solution.

While onsite at a customer I was asked is thier any way to copy specific standard iProperties from the model into the drawing? My response was use the Copy Model iProperty Settings from within the document settings of the drawing template. With this option configured common iPorperties such as Company, Description, Project, ect… need only be filled out in the models then copied into the drawings.
