| curved, hollow pipe. | Edmundajw | 2/10/12 5:35 PM | SketchUp Version: 8 Proficiency: Beginner. Hi, I'm wondering if anyone can help me with a problem I'm having while trying to create a pipe with a 90 degree turn. I've achieved it by drawing a circle, drawing a smaller one inside it, drawing a line u |
| Re: curved, hollow pipe. | Gully Foyle | 2/10/12 6:45 PM | I think your problem is not really with SU but with the design of your elbow, which has a bend radius smaller than the diameter, causing the pipe to turn in on itself. Also, the bend is not tangent at the straights, making it more of a mitered elbow |
| Re: curved, hollow pipe. | Bestistmate | 2/10/12 6:54 PM | hi edmund , Rather than putting your follow me path at the center of the circle move it to the outside of the outer circleand it will work then . if you want it in the center then you must increase the radius . check out skp file phil |
| Re: curved, hollow pipe. | Edmundajw | 2/11/12 7:52 AM | Hi, thanks for the replies. No I'm not sure of the dimensions. I just kind of made thisd to get an idea of what it will look like, and how to do it, with the intention of doing it with the right dimensions afterwards. I will try your suggestion Besti |
| Re: curved, hollow pipe. | Edmundajw | 2/11/12 8:53 AM | Hi, I'm probably just being stupid, but I still can't get it to work. And I'm not sure how to make sure my path for the curve is the same diameter as my circle. I create the arc by first drawing the line it's going to, and then putting the start and |
| Re: curved, hollow pipe. | Gaieus | 2/11/12 9:09 AM | Your radiused path is on the outer radius of the curve. Put it into the inner radius (and then you can make it much smaller, too). |
| Re: curved, hollow pipe. | Gully Foyle | 2/11/12 9:22 AM | If you'll pardon my mentioning it, that's kind of a backwards approach, since the dimensions are not just an incidental detail: they determine what the thing looks like, not to mention making the difference between possible and impossible geometry.

| Re: curved, hollow pipe. | Edmundajw | 2/11/12 9:35 AM | Thanks Gully. I'd say I'm only a beginner so am always learning. So thanks very much for that. I'm not entirely sure how to do various things, but I'll try constructing it with that value. Thanks again. Edmund. |
| Re: curved, hollow pipe. | Gully Foyle | 2/11/12 10:53 AM | That's okay. I just wasn't sure at first whether you had special design requirements or fit-up constraints forcing you to use a very short radius. I'm also not sure what medium you are putting through the pipe. I some situations. like air ducting, yo |
| Re: curved, hollow pipe. | Edmundajw | 2/16/12 6:28 AM | Hi guys. I've been trying to do it based on your suggestions, but I still can't get it to work. Gully, when you say the center line bend radius, do you mean the path, from the centre of the circle, has to have an arc of a radius of 1.315 times the di |
| Re: curved, hollow pipe. | Gully Foyle | 2/16/12 11:51 AM | Okay, Edmund. I'm slightly embarrased to confess that I misread the dimension table (hey, I'm old). Short-throw elbows can actually have a 1D bend radius, not 1.315 D. Here; see for yourself:http://sketchup.engineeringtoolbox.com/stainless-steel-long |
