[Tutorial > Modeling] Another Curve That's Got Me Stumped

Shaun Tennant

Bernard, could you post a picture of what the cord should look like? I don't know that i can help, but I would like to try, and I don't understand what the cord should look like..

Okay, I gave 'er a rip, I am using a really slow laptop, so, the imperfection will have to do. I just started drawing lines everywhere I thought the cord would shoot out into in 3D space, then I smoothed them out with curves.. then messed with follow-me, which took this machine forever, so I won't really be too interested in going back. You can see my rough path if you go into Xray mode..
I actually couldn't manipulate this file even in wireframe, so either it's wayyy too heavy, or

Bernard,
An easy way, based on Eric's Method using a VERY useful Ruby Script.
(Great for Pipes, Tubes, Cords etc etc)
...

Download Ruby Script from Didier's Website here:
http://www.crai.archi.fr/RubyLibraryDep ... o_page.htm
"PipeAlongPath.rb" (Thank you TIG for this great Script).
...
Copy it here (Plugins Folder) (if you have a Windows PC, I'm not sure about Mac's)
C:\Program Files\Google\Google SketchUp 6\Plugins
...
Draw guidelines (cord / pipe centreline) as per Eric's method as required.
...
Use PipeAlongPath Script - which has now appeared in top Menu
Plugins - PipeAlongPath (See Scene 8 in attached *.skp)
...
(See attached)
Hope this helps

Regards

Howard, thanks for that. I have inquired about pipe along path before but never tried it. Well I finally did and I love it. Makes the steps much easier. Thanks again.

Bernard, do what Howard says

Gaieus

Guys as I understand Bernard's biggest pain is to create the proper pathfirst of all! Unfortunately the radio with the grid confuses mee too much to understand what exacly he is trying to do. Maybe looking into it a bit more will allow me to see.

Thought I would share just a slightly different approach than already posted.
I was confounded by this very thing just a couple days ago,and here is an approach I used.
The "Grips" I beleive allow for a little more flexability in adjusting the path.

Charlie, that is great. I never knew you could add grips to a welded curve. Good tip.

Here's a another with a generic electrical cord cross section. I made the plastic a bit too shiny.

Thanks Eric..........But as the saying goes,every now and then a blind squirrel finds a nut.

Charlie,

What a great tip! I didn't know this, either. Thanks.

Also explode same curve and use the Smoove tool on it. A 20' radius worked well on the example.

Gata,
Clever use of the smoove tool,never occured to me to try it,Thanks :~)
This is great collaboration,gotta love it.

modelhead,
Can't wait to see the coaster,i want a front seat 8O .

Thanks to everyone who helped solve this problem - one that has been bothering me for some time.

As I suspected, it now seems embarrassingly simple. As Gaieus said, my problem was drawing the single line curve through 3D space.

Eric [Boofredlay] - a simple, clear and efficient method that I will now be able to use on other models. Very much appreciated. Shouldn't this go on the Tutorial Forum?

Jim - yours is another simple method that would work because you could vary the size and shape of the two curves to avoid other objects that might be in the way. Many thanks.

Shaun - I appreciate your efforts. You got a lot further than I did. You actually had curves which is more than I could manage.

Howard - I intended to use this ruby plug-in or one like it but had to draw the curve first. Thanks for pointing me in the right direction.

Charlie - Your "Grips" seem as if they would make a job that I would hesitate at doing in the first place, a lot easier.

This is what makes this forum so great - one problem and so many members willing to help find a solution. Again, many thanks to everyone who helped.

Ah, that is interesting. the "grips" work by actually breaking up the welded curves into segments again, but the segment endpoints are at key positions with welded bits left in between. Neat!

Good idea Bernard. I will move it and leave a shadow copy in the Pro Users Forum for a few days.

Bernard Hagan

Here is a tutorial [a bit heavy] showing how I created the electrical cord.

I'd be still struggling with it if it weren't for the help I received here. Again - much appreciated. The radio, shelf, plug and socket I built in Lightwave using nurbs so it looks a bit primitive in SU. Still some work to do on it. The cord could be a lot smoother if I spent more time on it - though these old fabric covered cords had a tendency to retain their kinks.

I'll leave it to the powers that be to move it to the appropriate forum.
