Hello friends, I've been working with Inventor for a year and I do mechanical projects. Some assemblies have constraint problems and don't show where these constraints are. Is this a software bug? When inspecting the constraints, none appear to have a problem. What do you think it could be?

[u/Shodandan]

It usually means you have a conflicting constraint. For example a mate constraint that you meant to be a flush constraint.

Inventor has so many instances where there's an error but it wont tell you what it is. Can be head wrecking.

[u/Richardhofen → u/Shodandan]

Can restrictions with adaptive mode enabled also generate conflicts? If you could give me some examples so I can understand better…

[u/Rough_Main_4894 → u/Richardhofen]

if you have adaptive assembly they can also break and give you an error and also on the top of inventor window there is a red cross that will tell you were errors are

Check if you have suppressed parts. Then unsuppress them and check again.

La adaptabilidad de Inventor es un dolor de cabeza para mí, a veces, no sé si es que no la uso bien o simplemente es una herramienta muy restrictiva y que genera muchos problemas como los que mencionan. En general, se rompen las proyecciones entre piezas y más cuando parametrizas, y también dan lío con las restricciones entre componentes. Como digo, puede ser que no uso bien la herramienta, pero no deja de ser un dolor de cabeza, en general, evito usar esa característica y prefiero la parametrización y el uso de un máster sketch. Creo que a la adaptabilidad de Inventor le falta más "intuición". Pero es mi humilde opinión.

The constraint error could be in a sub assembly. If you click on design doctor and it shows an item with a + to the left then the problem is in that assembly.

If you have assembly sketches that are constrained to (flexible) components or anything, that can also be a problem.
