flatten this part?

Greg,

Here is your flat "capable" part

If our want the flat pattern, suppress Process-Bend1 in the Feature tree.

Greg,

Try this way- start with just an arc(see doc1)

After desired sketch select base flange(sheet metal feature) see doc2.

Set parameters(k factor=.428"),thickness(t=12mm in your case)

After setting - click ok.

From tool bar(must add to tool bar) select flatten - will give you flat.

In order to add holes in flat you have to unfold first,add holes,fold.
