Flange tool question

[dwoodville]

I'm looking to create flanges to fill in the corners on my attached drawing. I have not been able to find a suitable way of doing this. I've attached my working file along with a .jpg of what I'm trying to achieve (disregard the angles written in on the drawing). Any tips out there?

I'm sorry my attention to detail has been poor lately- I didn't see your attached file. I'll take a look at it. Thank you.

How in the world did you loft one section at a time? Each time I go to loft from the bottom sketch to the top rectangular sketch the tool lofts all the way around and fills it all in.

Step up the timeline, they are surface lofts, one line to another line, the 1st 3, are top to lower bottom, the two intermediates are left to right (body edges).  I did not select the top rectangle, until the patch, but could be a loft if needed.

Step the timeline, Edit Feature to read the settings and selections, cancel to exit.

Excellent thank you! I didn't realize it was a surface loft. I appreciate your help so much.

It worked! I was able to make what I needed to based on your help. Thank you very much!

Ran into another problem when I worked with my original file. If I loft all the pieces on this one then I don't have a radius to create later on which will not allow me to delete sections and create a flat pattern.

I made things work by re-doing some sketches etc. The only problem I ran into was when I went to thicken the body .25in. It wouldn't allow me to thicken it with a negative value (-.25in). I had it all setup and drawn to thicken it in the negative direction. I settled for a -.125in thickness for now.

@TheCADWhisperer  did you ever get around to playing with this? I still think there has to be an easier way than what we've done so far in this thread.

When the 5 lofts and the patch were made, they were all stitched together to become one body, the seams are then filleted, (6.35mm) before removing the ones where you want the  "rips".

Fillets only work on the same body, not across a seam between two bodies.

My frame sketches were constructed for accurate inside dimensions.

Once you have the foldable surface, thicken it, convert to sheet metal then the flat pattern will work.

Doing half and a mirror, reduces the work load, 

your file has half of the work in 2 components, which I don't follow.

I appreciate your help and describing what you did, it helped me.
