Multiple helical parts in an assembly
Multiple helical parts in an assembly
(OP)
I am having trouble making drawings with more than one helical part on
a common axis. The actual part is a helix made with round wire that
has several thousand turns. Obviously creating such a part causes
problems with file size. Instead of making a single part with so many
turns i tried to detail the part as an assembly with two helical parts
of about ten turns each on a common axis.
i can create the individual parts and the assembly model with no
problem. My difficulty comes when I try to insert the drawing views
in the drawing. The drawing displays properly in wireframe mode, but
when I change to Hidden In Gray or HLR the coils look like they have
been through a meat grinder. Has anyone had a similar problem?
Any possible solutions would be most welcome.
Thank you

Then add specific information via custom properties for you BOM.
I would guess your fabricator could make this part from a "pretty picture" and some specific data.
Trying to show a thousand wire turns on a part is like trying to show screw threads - no practical need.
Remember, at the end of the day, most of us are still just making drawings for the shop.
3d modeling is super-great and loads of fun, but its easy to get all wrapped-up in the accuracy you can get in your models; and then try to get the same in an assembly.
This is a lesson I'm just now learning, I wish someone had enlightened me before now.
Let me know if you need more specific suggestions - more than happy to help.

If I ever have to make a model/drawing of a spring or lead screw that is longer than 8 inches, I'll simplify the part to have helix-based features only on the ends, while the middle portion of the length is a simple solid shape. This way when I get ready to do the drawing, I can Insert>Break and have a workable drawing and model doesn't suffer any performance loss.
