here is my problem,
I am trying to flatten this part but for some reasone i can't any ideas?
Your part is not a sheetmetal part. It also seems to have a lot of unnecessary bodies / surface bodies.
If possible, get the original SW files.
If not possible you will need to convert the part to sheetmetal. To do this it will need a flat area at some point. I've begun to convert the attached part to give you an idea.
I understood what you did but when you converted it to sheetmetal it only converted a partial of the body.
how can I fix it so that the whole body will be converted?
There are some tangent lines breaking up the surface. If you can remove these lines then the entire face will be converted.
I can't open your file
I am using SW2012 is there a chance that you could upload it again in a way that i will be able to open it?
Here you go.
