View Full Version : Wire Bundle Along Path

Hoping someone can help me automate this modeling process a tad.

So I have this bundle of wires that has been rail extruded. Pretty straight-forward. I would like to put a spin on the bundle along the path. I'm hoping there's a better way to do this than modeling the bundle straight, then apply the spiral, then modify that bundle to my curve. Any suggestions?

Use the same curve used in the rail extrusion process to create skelegons... got o layout and convert skelegons to bones, rotate the bones... save transformed and load back into modeler. shouldnt take but a couple minutes to get teh result you're after.

Brilliant, thank you. That should do it!

You could also keep your wire bundle as a rig instead of save transforming it out. This way if you have to modify it you just adjust your rig setup.

There's also bryphi77's "motion info extrude" tutorial that does something similar to what you want.

Hope it helps :)

Unless youré not supposed to animate it, and model is only what you want?

I would use px_bezier, free plugin...check erikals youtube clip on how to twist a cord, if that is something close to what you want?

Consider using DP Spline Transform

It is awesome, interactive, Layout based and can be built upon. Reverse engineering a specific path may be a pain though, the question is whether that path is needed exact as it is..

I'm no fan of locking stuff into position in modeler when interactivity can be kept in Layout.

Thanks for all the helpful suggestions. I'll def give more of these a go tomorrow at work. Nothing in the model is locked, just looking for an effective way to knock out a shot and expand my skillset.

Also doesn't LWCad have something that would allow you to twist as it extrudes? I dont' have LW on this machine so I can't find the exact name of it (sorry).

If LWCAD doesn't, which I'd be surprised if it didn't, there's Rope Editor.

It would entail a lot of back and forth, but doesn't PATH EXTRUDE allow this....YES. Attached is a screenie of a five disk object extruded using a (sloppy) Camera path.

You can set up a LWCAD spline and then use Profiler to extrude along the spline. Then selecting any point along your spline, rotate to twist the profile.

This also allows you to keep the original spline, should you want to add in a secondary wire or profile.

EDIT: Sorry, edited this bit out as it was a bit misleading. I don't think you can save multiple shapes as profiles (e.g. 6 circles in your case - starting points for the wire ends).

+1 the more 'modeling' you can do in layout the better...

this is a pretty good summary of what it can do

You can also use Magicbevel for this.

for this I would use Hair blade (http://d-creation.sakura.ne.jp/plugin_latest.htm )...you create a profile in modeler, in this case a few circles, then draw the curve with any curve tool, and apply the hair blade. you can edit all the points in the curve, twist, scale, etc. and it's always editable. When you want to render you simply freeze the curve and it even makes uvs for you.

Nice find Zardoz.

The link has ')...you' at the end and therefore goes to a 404.

BigHache, did you manage to get it to work for you in the end?

I think Pictrix C_Worm could also do this?

C_worm...Hmm I donīt think so, I am aware of it and tested it some time ago, but you canīt pick poly group extrusions or work with multi curves.
Px_bezier however..can extend multi selected polys along a spline path with twists and rotation to get cord like wire bundles, check erikals videos.

A fantastic tool would be a blend of pictrix bezier curve but melted together with the options for C_worm.

The whole "you're stuck w/what you model" Lighwave paradigm is SOOoooo 1990's: I certainly hope there are more EDITABLE meshes in the future, so we can actually adjust (!!!!) extrusions in the future, aka LW12.

Some 3rd party people seem to have accomplished this: at least the components of their extrusions, for example, remain editable in LWM, so although still requiring ping-ponging and Freezing, at least it's POSSIBLE.

Whatever data architecture they're cooking up for LW12, I hope it allows this.
