But on this one model it was not working – why? Normally you can type a value in the field, hit the enter key, and the model will instantly update. Just as a final tip – I was with a customer recently, entering values for parameters and iProperties on an iLogic form. We won’t chat about those here, there’s tons of information available online.

for an iProperty change, Parameter change, etc.

You can of course use an iLogic Event Trigger to specify which rules should run on a more global basis – e.g. To prevent this, and force an update when your rule has finished running, I tend to use these two standard lines (you won’t always need the first line). If your iLogic rule is actually running, but you’re not seeing the changes in the model, you may have the little update ‘lightning bolt’ in the top left of the Inventor ribbon menu. This rule below will now run when the Colour parameter changes (even though the Colour parameter may not be referenced elsewhere in the rule at all)Ģ) Put an update statement at the end of your iLogic rule Well – you could add a dummy variable at the start of the iLogic rule to force the rule to run when that particular parameter changes. How about if there is no ‘blue’ parameters inside my iLogic rule? You can test this very simply by adding a messagebox in your iLogic rule and it’ll pop up with any changes to ‘blue’ parameters referenced inside that rule – try it! So for example, the following iLogic rule will run automatically whenever the ‘Length’ parameter OR the ‘Width’ parameter is changed absolutely anywhere on the Inventor model (including in a form).

So firstly make sure you haven’t ticked the ‘Don’t run automatically’ option.īut hold on a second – ‘Run Automatically’ - what exactly does this mean? Well it’s very simple – if there are any parameters referenced by name inside the iLogic rule, they will be highlighted in blue, and they will then automatically be set as a rule trigger. The screenshot below shows the default settings in here – as you can see this particular rule is set to run automatically. The Options tab inside an iLogic rule allows us to control this.

Well there are several things to check to make sure your updates happen automatically…… let’s take a look…ġ) Check that the required iLogic rules are set to run automatically. How can I get my iLogic form to automatically update my model?
