How would you route a wire through this slot and wrap around the square post on the left?
Create a 3D path then sweep circle on that path.
Yeah, I thought that was the way. Just not sure where to start. I want the wire start perpendicular to the coils and be tangent to certain surfaces of the dark gray part before wrapping around the square post.
Getting the 3D path is almost impossible. I place a line down and it is way off from where I actually want it to be.
Yeah, free form 3D sketches are, well, sketchy. What you can try is create several 2D sketches in various planes and use those to guide the creation of the wire. You will want fully defined 3D lines and curves or else your wire will fly off in all directions. Explore the various ways 3D curves are restrained; it's not the same as 2D construction.
I have done a lot of wires and tubes. It is mostly just when a manager asks, "Where's the wire?"
try sketching the projection in 2 2D sketches and using the "project curve" with the skecth on sketch option.
I got one side close to being done. I still used 3D sketch for part of the path and made lines parallel and concentric to specific surfaces or edges. I haven't tackled the wrapping of the post yet. I just left it hanging for now.
Take a look.
Wrapped the wire around the post. Just kept using Boss-Extrude and Revolve until I made it all the way around a couple of times.
that looks prety good.
for an alternate method for the square post section, you can look on the forums for square and non circular springs.
ok, when you have to set up a complex 3D centerline, for a wire route, surface bodies and face curves are your friends. In your model, create an offset surface consisting of the four sides of the tab that you're going to wrap the wire around. Set the offset distance to half the wire diameter and fillet the corners to your minimum bend radius. On one planar face of that surface you want to draw an tooth pattern going up the face (this is a 2d projection of your wire path onto one face of the tab) and apply it as a splitline to all of the offset and fillet surfaces. This should give you a helix wrapping up a box. Edit your wire path sketch and use convert entities to make a 3D spline on the splitcurve. That will get you one layer of wires wrapped around your tab. If I had to create multiple layers of windings, like on an armiture, then I'd look at using an equation-driven spline in my wire path sketch. You have to have a pretty good understanding of vector functions to do this, but it's probably the best way to draw complex 3d paths. I'm not at my CAD station right now, but I'll try to follow up with a ost that has pictures to explain.
