Hi there, I am facing a weird problem and need help. I ma gonna explain in sequence.

1. I made an open profile 

2. Then standard of sheet metal making with base-flange, as you can see in the tree manager.

3. standard cut extrude.

4. then unfold

5. cut extrude.

6. then folding again

7. when flatten then its happening like this

Now my question is how can I make this flat pattern on horizontal plane (in scene view XZ) instead of in vertical plane (XY) ???????????
