Option to suppress warning "The assembly cannot be solved."

[jpeters4MKUS]

I have an assembly in which I decided to change parts into iparts, resulting in relationships with missing geometry. For every relationship I solve, I get the message "The assembly cannot be solved.  The new relationship conflicts with extisting assembly relationships." The message is there because I have not yet fixed all the relationships. I am aware the model is still broken but that it is not as a result of the relationship I just fixed, and thus select "Accept the relationship".

With a large assembly comes lots of relationships that need fixing. I would like to be able to suppress this prompt altogether, or at least set it to only show up when a new problems have been caused by my recent relationship change. I think this would improve my workflow.

Hi @jpeters4MKUS, this option actually already exists. If you go to Application Options --> Prompts and check ON "Do not show messages for pre-existing problems", Inventor will warn you once about all the broken constraints, and then won't warn you again unless NEW constraints become sick.

Also, you might try working with Defer Updates ("Manage" tab --> "Update" panel) turned on, which will just pause the assembly re-solving until you're done making your edits. You have to be vigilant to keep up with what you've changed though, since you won't get any feedback from your model.

Finally, another thing you can do, which can sometimes be a little better than Defer Updates, is to just suppress all of the sick constraints except the one you're currently fixing, fix it, unsuppress the next one and fix it, and so on. This way you can see your assembly respond to your updates without having all the sick constraints also trying to solve. One downfall to this is you can't edit a constraint before un-suppressing it, so you might have some undesired assembly changes after un-suppressing your constraints. However, you can vote here for the ability to edit suppressed constraints, which would make this workflow more efficient: Let us edit Suppressed Constraints.

Thank-you for these suggestions.

"Do not show messages for pre-existing problems" is not behaving how I expect. However,  I just tried "defer updates" and it had the desired effect. Thanks.

I've been wanting to be able to edit suppressed constraints for a while. So I've voted for that now.

I've attached a few images to illustrate the behavior I'm see seeing with "Do not show messages for pre-existing problems" on. See captions.

Hmm... ok, I think I know why the App Option didn't help. Consider the two scenarios below.

Scenario 1:

Mate:1 has lost a reference.

Mate:2 conflicts with Mate:3.

You modify Mate:1.

Result: Inventor will not throw an error.

Because Mate:2 and Mate:3 were already broken before you modified Mate:1, and because Inventor was able to resolve Mate:1 after your modified it, Inventor won't throw an error.

Scenario 2:

Mate:1 conflicts with Mate:2 and Mate:3

You modify Mate:1.

Result: Inventor throws an error.

If you modify Mate:1, Inventor won't be able to resolve it after you click OK. And since it's the constraint you actively just modified, Inventor will throw an error letting you know that your newly-modified constraint can't be resolved.

Hopefully this example helps you understand which scenarios the App Option will help with an which it won't. Basically, if the constraint you just edited can ITSELF be resolved without conflict, Inventor won't throw an error even if there are still other pre-existing conflicts. But if the constraint you just edited ITSELF conflicts with other constraints, Inventor has to throw an error to let you know this.

This is why it would be really nice if Inventor let us edit constraints even while a Positional Rep is active. Because if you're using Master, you're going to have conflicts unless you suppress just the right constraints. And you'll have to play whack-a-mole with these constraints as you try to fix your different positional reps. It would be much easier if you could just edit constraints while in a Positional rep.

That would probably be the best solution to your situation, and if you created a request for that ability, I'd vote for it 🙂

Or it would be nice to have the option to have it always default to a certain option for this dialog. For instance, always have it select "Accept" and can see the errors/issues in the Design Doctor or Browser and fix them at a later time.

I also wish this warning could be turned off.

When I am revising an assembly (which I usually am following design meetings etc) I know that mates and constraints are in need of attention. Theres a big design doctor red plus sign at the top of my window. That is all the warning I need.

I dont need any windows popping up interrupting my workflow. A little red cross is more than adequate.

If I had a choice I would turn off ALL pop up warnings.

I think the good folks at Autodesk have an entire department dedicated to figuring out new and creative ways of wasting a users production time. They are committed to providing useless warnings and flags so you have to interrupt your work and concentration by moving away from what you are doing to go click it off.

This thread has been open for 6 years and still no fix for this. If I'm fixing one of several broken constraints, I should NOT get an error message telling me that the other constraints are still broken. These pop-ups are a monumental workflow stopper. "Do not show messages for pre-existing problems" doesn't suppress these annoying messages.

This feature is absolutely annoying and a waste of time for the designer who's fully aware of what they do.
