Updating assemblies after changing a part

[chandrayaan]

I have used Fusion360.
I am new to freecad.
When I updated the assembly after editing the parts with the A2 function,
The joints are ignored and the parts do not move.
Is there a mode that allows parts to move according to their joints after part update?

Welcome chandrayaan,
I'm not sure what you mean by 'joints'. could you post your assembly and parts? also the steps you take to modify your assembly.

joints is the addplane coincident constraint. I wrote joint because I didn't know the official name.
If I change the dimension of flame2 from 130 to 100,
The position of flame2 will be reversed.
Is there a way to keep the flame2 in position while working?
