Hi,
As @TrippyLighting mentioned, we discourage using the move component workflow. There are many reasons for this
including kludging up the timeline and causing various performance issues. A preferred method works like this.
You would typically have one grounded component, usually the first one but not always. You then have a couple of
choices about how you go about designing the other parts and joining them together. One method involves working
around the Origin and designing your following components. In order to do this you often have to turn the visibility
of your first component or assembly so you can actually see what you are doing by using the little eye icons in the
browser tree. Once you have designed the new part you then use a joint to place them into the assembly and start
on the next part.
The second method is by directly building off the previous part and using some point on the part as your origin. This
allows you to actually create the part exactly where it is meant to be in the assembly but it isn't yet joined up to the
assembly. To join it up you would use an As Built joint. This is called the building in place method.
Both of these methods avoid having to move the various parts of the assembly around except when you create the
joins. You should be using the visibility eye icons when you need them to see what is going on and avoid moving parts
out of the way so you can see. Every time you move a part it creates a move in the timeline that fusion calculates
from. If you have multiple moves then fusion will be recalculating each time before finally calculating the final
position. This can affect performance quite severely on complex assemblies.
So the bottom line is - design at the origin or in place; use joins to connect the parts of the assembly; turn visibility
on and off as required to see what you are doing; ground only one part unless it is absolutely necessary; avoid the
move command;
Cheers
