Telephone Cord Modeling

[bilalbajwa]

I found this model online free. I was rolling back the feature and was trying to figure out how the modeler modeled it. Any insights are highly appreciated.

Thanks

 

I am unable to attach a file greater than 250KB do u know a way i can?

 

For now here is the txt file that contains link.

 

This is a folder of many curve driven patterns you might find some interesting and i am concerned about the phone cord model.

Cool model. What are you getting stuck on?

[bilalbajwa]

Got lost at surface sweep1. See how the cord is following the point intersections of the sphere and the base sweep. If you open up the surface sweep 1 feature you will see a 3d sketch 7 where that come from? Just don't know how to do proceed? Coold thing is the cord is somehow programmed to follow the intersections somehow.

It looks like he created a 3D spline, using the points where the spheres intersect the base-sweep as reference.

I was able to recreate 3dsketch 7 by creating a 3dsketch spline using the points I described in earlier post.

Here is my version of the cord. What do you think?

The thing is when you increase the length of the cord everything follows the pattern. If one just do 3d spline it should stop and shouldn't be effected by the increased length. Give it a try. Just increase the length of helix. You will see what i am talking abt.

Yes, by stretching the helix the 3d spline is affected. This is because the spline is referenced to the helix. Remember, we are dealing with parametric modeling. We are able to make changes without the need to create a new model. When modeling a part pay close attention to you relations, this is very important for parametric modeling?

 

Did you download my part? I used a different modeling technique than the one you posted. I used the intersection curve tool to create the spirals on outside of the cord.

that 3d sketch was done exactly as bill said. The guy who created it manually drew a spline by clicking on the intersection points on the spheres. It seems like a bad way to do things though. Im not sure what version these parts were drawn in so that may have been the best way.

 

Is this cable something you want to draw, or just something you found?

 

Bill, how did you draw yours? since I can't look at your files im curious. I may give one a go here shortly.

Here is a shot at something similar. I couldn't do the last sweep because of file size, but you can go in a sweep the circle along the Curve. You need to change the options to "Twist Along Path", change "degrees" to "turns", 50 turns and probably will need to change the direction. I don't know that ive seen a phone chord like this before though.

Welcome back. Attached is link of how I created cord - one side. Enjoy:)

very nice bill. I like your method of using the surface and original sweeps intersection curve rather than the original links method of manually creating a spline. I believe that was the links only way of making it a Curve driven pattern like the rest in the download. The only thing I didn't like about sweeping that way with the circle planar with the original sweep is that it stretched the sweep out to an oval i believe. Did you notice that with yours as well? I ended up making a plane 20degrees off to remedy this for the sweep.

 

 

on a side note, how do you like the new quick menu setup in 2010. Did you use it in 2009? I think the 2010 version looks easier to use.

Thanks Matt. I will experiment with the part and see if I can duplicate the oval effect. I will try your plane resolution as well.

 

The menu takes time getting use to. The mouse gesture feature is cool but I feel the diameter of menu could be bigger. Let me explain.............when you right click and hold in the graphics area the mouse gesture menu appears. As soon as you hover over an icon it becomes selected and active. My issue is that I have my mouse speed settings set to high and its very easy to select the wrong tool. If the diameter was bigger, I would make less mistakes.

Do you use the quick menu key "S"? Thats what I use and its just a quick tool bar that you can add anything to. Sketch, part and assembly menus are all different. The 2010 menu is very similar to the Acad/Inventor steering sheel setup except theirs is for view manipulation. I find that hot keys for features I use is the best for me.
