Uneditable models.

[Anonymous]

Some models downloaded from internet are impossible to modify. Almost all commands are greyed out. Does anyone have an explanation? See picture.

All models downloaded from the internet are editable.

But they will not have a feature tree unless Feature Recognition is run.

In some cases the FR will not recognize the features, but some way, some how - the models are editable, just might take more work.

For your spring, I would simply recreate in Inventor.

Your screen shot shows assembly environment.

Part modeling tools are available in the part modeling environment.

Thanks for your reply.

But it isn’t just the feature tree missing. I’ve attached a valve example. I can’t change for instant the BOM structure.

I assume that it's something simple, but I sure don't know what!  The file appears to be locked.  All tools that could have any effect on the model are unavailable for selection.  Anybody else know how a file can get in that state?

Interesting, I'm curious as well.

A round trip through step makes it editable, though.

The part is a Derived Component with the link broken.

I think the original from which it was derived would be needed to figure out how it got to this state.
