Sorry Mitch, there was no file attached to your post.
yes, there was an error when posting. I didn't even think it posted at all.
I keep getting a message "an unexpected error has occured" every time i try to attach the file.
I have tried different drawnings, even word documents... nothing uploads.
I will keep trying periodically and again on my home computer if I don't get it by then.
I will add a new post to the thread to indicate sucess.
We often have the same Problem.
Here is an example. Try to delete all appearances or put new appearances on the faces / bodys in the assembly or in the parts and go back to the assembly an rebuilt the model.
Nearly everything will be set back.
