I can't open your file. I'm on SW 2017, is that why?
But in this case, why don't 288° cuts (5 sections) work either? Is it because of the method I chose for the removal of material? I'll give you the version I made like this.
For the method, for each piece of coil I create 2 new 3d sketches with the sketch from each Helice/spiral converted into a 3d sketch then shortened and constrained in relation to a plane (top plane) then with these 2 sketches each time I create a transition fold. And there is no problem for the unfolded.
If I understand your method correctly, in each 3d sketch you create a small part of the spiral? Maybe I don't know how to use the "convert entities" function to convert the spiral into a 3d sketch, but do we agree that it's not dynamic? If I have to change a dimension, I have to redo each sketch one by one (i.e. a small bunch of steps in total).
Not necessarily a bunch of steps if you use variables that use basic trigo or a rating control table (@sbadenis will explain to you ;-) ;-) how to do it with a table).
PS: @sbadenis a super big Congratulations (I love it) for your proposal, it's super simple and tasteful and in one room on top of that. Simply Fortich'
So I managed to get everything I wanted! Thank you!!
I admit that if you had a little tip to give me to make it dynamic, I'd be very interested, for now, I have to redo my 10 3d sketches each time for each modification of my spiral.
Small problem in your design, the 2 end points of the 3d sketch must be on the same plane passing through the center of the tube. To achieve this you create your 2 - 3 or more planes and then you constrain the endpoints of the 3d sketches on these planes and in addition it should be dynamic.
Even if I'm a fan of trigo Zozo_mp, I'm also in favor of the least effort! So I let solidworks calculate for me!
Oooh I see! I had gone through a 5-segment split of my 3d sketch but your method allows more modularity afterwards! Bravo, it's great! A bit tedious to constrain the 20 ends of the propeller portion, but the result is exactly what I want!
Thank you again and congratulations for the beautiful method proposed!
