Lighting lamp

[malakin]

hello to all

I should make the lamp in photo with inventor, and I find myself a little in trouble with some steps. . .
Meanwhile what I managed to achieve is the variable step spiral, but I couldn't change the form of the sketch to every revolution to decrease the amount of material gradually, keeping the shape of the spiral. .

would anyone have any suggestions for what to do? ?

being a little prevented in the use of the forums, I have no idea how to attach the project that I managed to realize, so that you can understand where they are. (if anyone explains me well)

thank you already for the many answers that will arrive (spero) I wish you a good day! !

greetings alessandro

I attach a possible solution, clearly to fit your needs.

you are a genius!!!!!!!!!! I had hung myself on the coil command, or on the realization of the trajectory of the propeller on a 3d sketch with the helical command curves and then draw and various sections and join them with the loft or sweep command.

I didn't think about bending the sheet. you are actually one of methods to achieve it. .

Thank you very much
