Scaling problems

[sennaboonhof]

Hello.

I'm having problems when scaling my work down. 

So im working on a ferris wheel carriage, but I need to scale it down.

The problem is that when I scale my work down, it completely disassembles the whole thing. Even when I put everything in place with joints.

Does anyone know how to fix this?

There are no Joints in a STEP file.

What scale do you want (relative to current size)?

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Why do you need to scale it?

Wall thickness of the square tube is 4mm.

What will be the wall thickness after scaling?

here's the file. the scale I want is 0,08 from this file. the reason that I need this scaled is that my 3d drawing is the way how its like irl, but I want to 3d print this thing. The carriage walls need to be 2 millimeters thick.

...and if you scale by that factor how thick is the square tube wall that was 4mm thick?

.08*4mm=0.32mm

Will your printer print wall thickness of 0.32mm?

A couple of things to be aware of:

1. Fusion is timeline-based (assume you are working on a Parametric design), so the timing of the scale is important.  If you assemble components with joints, then scale the component after the joints in the timeline, the joints will use the positions they had when they were created.  If, instead, you scale that component before the joints, it should work.
2. As-Built Joints will not update with geometry changes.  As-Built Joints are convenient, but they are convenient because you do not have to pick geometry.  The lack of a geometry reference is what leads to the joints not updating as you expect, when you make geometry changes.

alr so, I've changed some things to the design. I now filled in the whole thing and added some things so its sturdier and a bit less detailed, but its still doing the same thing as it did before.

can you explain a bit more about what behavior you see that seems to be wrong?  You say "it completely disassembles the whole thing", but it looks to me like the joints before and after the scale are the same.

So when  I scale the carriage with the joints the distance between then stays the same right? But then when I go 1 step back and scale the whole thing without the joints the outcome is almost exactly the same. the only difference is that I now can move all the different parts, but theyre still all over the place (see screenshot). now the problem with this is that when I use joints to get them back together, the sides/lines that I wanna put together either just dont joint or they take a very weird angle. When I try to fix the angle with the motion "revolute" it said that the joint will block another one. Even when I dont have any other joints.
