Joints not having effect - moving body does not move connected components

[kierenj]

My workflow so far:

1. Create a parametric dodecahedron using a great screencast I found here - end up with a regular dodecahedron body

2. Import 12 x components, one for each face

3. Create a sketch on each face using construction lines to find the midpoint

4. Create a ball joint to move and align each component to the midpoint of each face, pointing outwards

At this point, I can edit the original parameters and everything adjusts nicely.

However, I now want to split the dodecahedron and move/rotate one half around. If I do so - or even if I just move the whole dodecahedron body - the components are not "attached" / do not move with the body.

How can I achieve this please?

Please share your design (public link through data panel).

Thanks!

Hi,

the reason is: You tried to create joints between components (LED) and Body (dodecahedron)

1. Create a component from the body.
2. what should the ball joint be for?

joints are only possible with components

Ok, so if I convert the body to a component, then create the joints, it should work?

The ball joint was a convenient way of moving and orienting the LED components to the faces. I could also move and align, but I suspect they wouldn't then be pinned in place for subsequent transformations or operations on the dodecahedron?

Incidentally, you're right that I tried to create joints between a body and components.. but also that I succeeded to do so: the joints exist! Is this something that's not really supported, but it let me do it for some reason?

Either way, I'll give it a go, thanks very much

- Convert the body to a component

- Create holes where you can mount the LEDs. Alternatively you can create joint origins or sketch points to mount the LEDs.

Hi @kierenj 

That's certainly not the desired effect. How did you see the attachment of the LEDs? The body does not contain any holes

[kierenj]

I've converted the body to a component, created another joint, and again, if I move the component, the connected component doesn't move.

I realise the body is solid with no holes currently - I'm looking to orient the LEDs, then use them to cut out an appropriate hole. That's not my question -

My question again is - how do I make it so that when I translate, or slice the main dodecahedron and translate pieces of it - the attached components move with it?

Please?

Hi,

You must also renew the joints so that the LEDs have a connection to the component and not to the body.

This way: right click joint > Edit joint  > delete C1/C2 > select new joint!

Thanks, but I recreated them from scratch after converting to a component. Moving the shape component still doesn't move the connected ones

Hello @kierenj 

Maybe you have to Fix The Main Component ?

I made a Screencast.
