Making a bending metal pipe

[juju1]

I've searched all over YouTube for a video on this but can't find one. I've watched a few on how to in photoshop to get the general idea but I can't get it to look as good. The way I've seen is making a rectangle and filling w a gradient and copy/paste and move it over. My prob is when I rotate the image to make the bend and copy its copying the rotated image. Can anyone help me w this or is there another way that's easier? Thanks

I don't quite get the problem. Do you have a URL for the tutorial?

[juju1]

Search "tutorial-cable interface wires" in YouTube. It's a PS tut but that's what I'm trying to do. Thanks for the reply

I don't have home Internet so I'm having problems getting the URL.

No hurry

Ok this what I'm trying to make. Think of a hose on a car (radiator hose) now think of one on a race car the ones that r not black and rubber but the ones that r like metal wire hoses. That's what I'm trying to make. If u know what I'm talking about make one and I'll tell u if it's what I want. And hopefully u can tell me how to make one.

Ok got it. So, your problem is when you are producing the multiple rotated parts for bends? I assume you are always rotating the initial element by gradually increasing angles, and not applying successive rotations using the last rotated element (this would create blur).

IMHO there is a much faster technique using a brush and a path, but it requires Gimp 2.7 or above, and it's a bit too long to explain right now.

Ya there has to be a faster way I agree. I made a .pat and .gbr and tried to fill a selection but the prob w that is everything I fill horizontal looks good but vertical looks bad.

The method I'm thinking about:
- create a brush (a bit like the first element in the tutorial, but widen the sides at the top to give it a slight butterfly shape).
- use the path editor to draw a path where the center of the braided hose should be.
- set the paintbrush to this brush, and use the brush dynamics settings that uses brush rotation (this option is new in 2.7)
- stroke the path using the paintbrush

Can u make a sample for me to see if it's what im after ?

See attachment. The brush used is the bottom layer, copied to the clipboard.

Doesn't wok too bad, especially considering that we are on rather sharp bend (bend radius: 200px, hose diameter: 80px).

Much faster than rotating/pasting it element by element. Requires Gimp 2.7 or above.

something like this
