Analyze Interference-Make & retain a measurable red solid out of the result

[gcross]

When you find an interference in an assembly you cannot measure the resulting red interference to help you accurately eliminate the interference. As soon as you start to measure the red interference goes away.

The information you get is not very practical to a lot of us. Who cares about the centroid & the volume? We just need the distance to change the parts to quickly eliminate the interference.

The dialog box should have a check box to retain the interfering solid for long enough to measure it & without adding the solid as a new part, of course.

Mechanical Desktop did this very well.

Didn't I see an addin somewhere that would build a new part / solid from the interference between components?

Although this can be done via an addin, it does seem like is should be built in. you generate the graphics already (the hard work is done) just let them remain on screen afterwards

It would also be helpful if it didnt show interference between threaded holes and the fastener.  When I run an interference check, that makes up 99% of the volume.  Its hard to decifer this out to find the "Real" interference.

+1 for option to ignore thread interference

These projects [US14609] [US14610] are under review by the development team.

Accepted ideas [INVGEN-572 & INVGEN-573]. Thanks!

I wouldn't use the word "ignore" for threads, I would say "let's be intelligent about thead interference". I think Inventor is smart enough to ignore two 1/4-20 threads that are interfering while still flagging out that you have a 1/4-20 screw in a #10-24 hole.

I've just recently moved to inventor 2015 from Solid Edge, which did this very well. You could save the interference as a new part so that you could reference it out of the assemblly level.

I'm assuming these changes US14609 and US14610 have not been implemented yet?

Thanks

I am doing this now (as a work-around) by creating a derived part and using the "Subtract" Boolean operation.

I would suggest for the current idea to have to option to save the result of the interference as a part file.

We are refining procedures around idea status.  Changing this to Future Consideration.

Hey Dan,

It's now 2025. Any chance something can be implemented in IV 2026 to give us a solid to measure? Every time I do an interference analysis I'm reminded of this sore need.

I could be wrong but I would guess that nobody that I heard of uses the centroid info that gets reported now. Our mechanical engineer wondered how that would even be done.

Thanks!

I like this!

Another route would be to present it directly in the table and have "floating labels" on each intersection (maybe only shown when you select them?), like this:

The X, Y and Z should refer to the current assembly Origin.

@gcross,

I totally hear you. I was hopeful back in Inventor 2018 that we might be able to make some progress on this request (while enhancing filters & appending more info within interference analysis results). Unfortunately competing priorities won over in the long run. This one does remain on our longer term radar. One question for you - would you find value in being able to conduct an interference analysis using designated Min/Max tolerances to evaluate the results? Similar to this request: request for a gap analysis. Thanks.

[gcross]

Dan,

I don't see value in using the interference analysis with min/max tolerance unless the interference can be easily measured in its entirety.

This brings us back to the original request to be able to retain a solid from the interference so it can be completely known & analyzed.

This ability has significant value to the work I do & most likely many others. Solid Works apparently does it very well from what I hear.

I can’t understand why it’s overlooked. Hope it gets some traction for next release.
