Triggering an iLogic Rule When Design View Representation Changes

[kparsa]

Hi,

I have created a conical spring in a part file. To be able to show the spring in both compressed and uncompressed states, I have created two views called Compressed and Uncompressed. In addition, I have created an iLogic rule which changes the length of the part depending on which view is active. However, the problem that I have is that (1) when the design view representation changes, the rule is not triggered, and there is no option for making it trigger automatically after a view change, and (2) even after the rule is manually triggered, I have to click the local update button to get the length change to show.

I know that I can create the spring as an assembly file with two parts in it, one showing the spring in compressed stated and the other in the uncompressed state. But I was trying to see if this can be done within one single part file.

Thanks in advance,

Hi

iLogic offers pretty limited way to customize Inventor when it comes to events unfortuntely. I don't think there is a way your iLogic rule can react to an event such as Design View Representation change.

This kind of customization is pretty straighforward to handle when working with either VBA or a .Net addin. You can use RepresentationEvents to trigger some custom logic.

You could also use an iPart which provide the kind of feature you are talking about out-of-the-box.

Concerning (2) did you try invoking Document.Update at the end of the rule to reflect the changes your rule is making?

Thank you for the response.

If I understand iParts correctly, that would require me to enter the length of my spring in some table. Whereas what I am trying to do is just switch between views.

I do have a line at the end of the rule for that purpose: ThisApplication.ActiveDocument.Update. However, even then, after any change in the rule, I still have to click the update button.

Thanks,
