Cable bend animation possible?
SOLIDWORKS Forums
1 month ago

I wanna to show cable inserting into some socket. That kind of movement would deform cable. Since composer cant influence on parameters like extrude, revolve, sweep etc., its kinda hard to do this...

 

There is 2 methods that I found on internet but both of them didnt suit my requirements:

 

1.) Scaling along X or Y or Z axis. This is good method but for big dimension cables where you can use 1.1, 1.2 scale and barely influence cable dimensions but my cable have small dimensions so I have to use 1.5 scale for insert and that scale influence a lot on cable thickness (since my cable is bend like L profile and 50% increase of thickness normal to scaled axis is just to big)... See attachment... So this method didnt solve my problem.

 

2.) I also saw people make cable with a lot of segments, and this method is painful and hard. But also since I use "sharp edges" mode I can see all joints as lines which i want to avoid. So this method is also bad solution for me.

 

3.) I did said 2 methods but there is this third one and I wanna mention it because someone could find this as solution, but its really bad solution. In this case you use animation path line as full and thick line that simulates cable. This could work but only to zoomed out views, but when you zoom in view everything scale up except that path which then appears too thin.

 

Do anyone have any solution to animate cable bending, flexing, changing position????

Re: Cable bend animation possible?

I use the polyline in most cases to show a cable. Polyline is a 3dimensional curve and the property "smooth" sets it to something which is similar to a spline.

You will be able to modify the nodes of this spline. But it has limitations. One of this is the size and it dosnt change ist size by zooming. And it is not realistic, like a geometry!

But in Animation or illustration you will be able to draw some cable very easy!

Thats same as path simulating cables, so in "zoomed situations" still looks bad...

That is correct. Zoom is no good Option for this.

But this is the only way to Show flexible lines as cable, ...

 

If you find any better way, let me know!

Scaling along 1 axis is good solution but for long cables with small "movements". For small cables with big "movements" there are serious deformations of cable as in picture I attached up. I guess this is bump. For now.

Re: Cable bend animation possible?

You are getting into a realm of animations that Composer doesn't handle well. While it could be done as you have mentioned using sections in your OP it's not time friendly but is the cleanest way within the software I know of. I would recommend doing this in post production with After Effects or an alike program. Depending on where your animations are taking you it might also be time to look at C4D or Maya. IMO Composer animations were designed for simple marketing / sales purposes not advanced animations. Keep us posted on your solution if you find one.

 

Cheers,

Derek
