Eliminate twisting from sweep around a helix
Eliminate twisting from sweep around a helix
(OP)
Hello,
I am having trouble modeling a multi-layered solenoid in solidworks. The issue arises when I sweep a sketch around a 3D curve that describes my helix. Although the sweep is done as "follow path" the shape is produced correctly for the first turn after which it starts sloping instead of staying horizontal to the top plane like I want it to. I have attached the model as an example. Please let me know if you have any ideas on how to fix this.
Cheers,
Sorin

I looked at your part, but I'm not 100% sure what outcome you need.

@vigildesign: I have tried what you suggested, it looked promising in the preview however it did not let me build because it said there would be zero thickness geometry. Did you manage to build your version after making those changes?
Also, I find it odd that this is the solution, I would really like to know what caused the problem in the first place because I need to be able to create multiple models like this with different number of wires/thicknesses and I dont want to use trial and error every time to figure out the angle needed.
@ctopher:
I have attached another part that is similar and does not have the twist I am talking about, however it is has an elliptical cross section.
@rbpmc:
There is no "twist normal to an edge" option so I cant select a horizontal edge as a reference, that would make sense though. I tried giving my sketch relations that say they must remain parallel but sw seems to ignore that as shown by the twist it creates.
If anyone has any more ideas it would be greatly appreciated!
Cheers
Thanks again for the help!

The inner wire (whose center follows the 3d curve perfectly) does not show this problem, it is only wires that are farther out. Does anyone know how to solve this?

So select Follow Path in the Orientation / Twist Type :then select Direction Vector : then set the twist orientation via a horizontal edge. Hope this helps.

Got the bumps out of the last model,
The first model you posted, I couldn't get it to work properly.. bumps are diminished though, but the last sweep(7) doesn't seem to cooperate.
