Dear community. I need your help.
I have tried to remix some different folded paper lamp-designs without success.
I would like to recreate the shape of folded paper like in this lamp:
The loft tool has been my tool of choice, and my first attempts do look OK, but I can’t figure out the geometrics of the changes in angle along the surfaces.
See my different attempts in comments.
Any suggestions of how to create a loft surface over star-shaped polygons at an angle? Or is my tool of choice the wrong one?
You might need a combination of loft and boolean subtract.

Thanks for your reply. Do you have some more details on what you think I should try. Maybe a screendumb?
Housework day today. Will show my idea tomorrow. Sorry.
Sorry for late reply. Very quick example should show what I came up with. Lofted the main body. Then made planes on one ridge’s line segment and drew triangles on them. Lofted the triangles into a shape to subtract from the main body. Pattern then triangle shapes around the main body and subtract them. Not very elegant and there might be a better way 
But with careful planning it should be doable.

You can further manipulate the Triangle shape using the move tool and bevel tool etc.

I found this post while trying some various lamp shades designs.
I realized the easiest way is to create these 2 sided roof and rotate/align them.
Hey Scalemodel. Your solution looks better than any of my attempts. Could you make a short walktrough as a sreencast?
Kind regards

Sure I’ll make something that would be helpful. I made it while back and kinda forgot how I did it, it was bit of a mind bender.
Came out good though.
For now here is some screenshots of what I did, this could be helpful.
I used Axis Line tool as a guide because they are easy to manipulate in 3d space.
After looking at my original attempts, I now know what the shape looks like so I simplified it.
The way sketch is drawn its bit confusing, but ignore that and draw the sketch exactly, it will give you well rounded look like the original photo. You can make tweaks later on.
Almost forgot to mention, the sketch was drawn with Control Splines with deleted curves controls. With control splines you can add more end points or delete them to get you more complex design, you can consider this a basic template you can use to modify.
