View Full Version : Don't Understand This???

Hi All, I have a lot of cables to do, and was thinking of sub patching them. I Made this as a test just to see how few polys I'm going to allow myself to work with. This was my method.

1. Created a disc with 12 sides, made to length.
2. Beveled the two end faces to the wall thickness.
3. Bridged the hole in.
4. Bandsawed the ends.

Then in Layout I conformed it to a curve, and I get this. There is nothing wrong with the model. All quads, merged points, no 1 or 2 point polys! What give?

If I boolean the hole in it works fine. Any help with this would be great! Running 11.6.3 on Mac 10.10.5. Thanks.

Be great if someone could replicate my steps to see if they get the same results.

I replicated and everything is just working fine. I did use thicken though. perhaps the curve you are using is too complicated and has lots of corner.

Hey Tony,

Well, I've got a bunch of questions. But instead I'm just gonna float a guess.

Looks like the interior (double sided surface right?) is not bending.
Bridging will give you long polys down the length with no divisions. Did you give the interior polys segment cuts down their lengths after bridging?
If not, I'd grab the loop of interior polys and hit "l" 4/5/6 times... or til you think you've got enough for the deformation.

Oops I just found a flaw in my own scene too. the problem is related to the Range End under the curve conform IMO especially when the stretch is turned on.

Try setting Range end to a value slightly higher than the length of the curve.

Yes, I figured it out just a minute ago. DuH!! Sometime I feel so stupid! LOL! I'm use to putting in the segments when I extrude the object. Some things are so obvious, and yet I miss them.

Do the cables really require interior geometry? Starting with this, they're just going to cause problems.

Inner walls are necessary; otherwise, when looked at from the end you see whatever is behind/under it.
Needed for realism.

Since they are cables, there are usually fittings on the end.

Not if double sided.

But I do see the need for wall thickness up close to an end (end caps would serve this purpose).
In the case of just a plain end, only run the interior walls for a short distance if you want.

Actually most of the cables I do either are bare, or have no connectors.

The internal geo still doesn't have to go the entire length of the cable. Unnecessary poly count if you can't see them.

How did you achieve the cutoff/clipped look of the cables in the second image Tony?
