This is not really an issue because I'm not searching a solution. The easiest way for me is to start again my drawing. But here is what happens.
I was making a blueprint of a part. A sketch of that part was open, and in that sketch, a block was open too because I was looking at some tolerances in it before making my blueprint. Then I have made some dimensions on my sheet, and I wanted to save my document. So I did, and then Inventor said to me that I have to close the sketch of my part before saving. So I clicked on the "Ok" button. And then, that happened...
And there was no way to put it back as normal.
Do you have a 3D mouse? If not you could up load the files here and I can put it back or anyone with a 3D mouse can.
Thanks for your help. I have no 3D mouse, but I don't need to put it back. I copied the views and pasted them in a new sheet and all went well. I just thought it was nice to share.
By the way, I tried to make it happen again, but I did'nt succeed.
Yeah it happen once with me before I bought my 3D mouse but it was back in Inventor 6. Did the same to fix it cpy paste..
But now with my 3D mouse it can be fixed.
