Hi,
Yes you did break RULE #1 but many rules are guides that you ignore at your own peril.
As @TrippyLighting says, you can only move things around if it doesn't break the links with other things. You are
much better off planning ahead and not having to move anything, but it does sometimes happen.
In terms of sketches and where they should live and why, it really depends on what you are designing, how complex
it is and, as you mentioned, is it related to other assemblies. I have used both a sketch in the main file and a sketch
with the part.
If the design is relatively simple then it doesn't really matter BUT, as a Designer and/or Engineer it becomes a case
of creating good habits and being consistant. There are arguments and design guidelines for both methods but I
feel doing things the same, correct, way each time is a better habit to have.
I find that I place my sketches in the main part, but if I create assemblies or must match another assembly, that I
place sketches associated with the assembly at the top of the assembly. It is about forward planning as you do not
always know how complicated a part or assembly will get. You also want to plan things so that it is easier to make
changes later if necessary.
A few suggestions to help your workflow.
The screenshot you have shows your part hanging out is space. Is this because you designed it in place or are you
designing it and then using a joint? Both methods are valid under certain circumstances. One thing you should NOT be
doing is MOVING parts around - it clutters up the timeline and causes issues. Either design parts using the Origin and
use a Joint or build them in place. If you are building in place then use Projection off the original part to orient the
sketch. I can see you have projected some points, but I also see a bunch of open points in the sketch that normally
means the sketch is not fully defined. Always fully define your sketch as it is less likely to break something later down
the track.
Why are you using Contact Sets? Contact sets do not work well with Fusion. A Joint with a Motion Link where you have
correctly lined everything up should not cause interference between parts. Use the Interference tool and a cross
section and zoom in close to line things up correctly.
Another thing RULE #1 says is NAME YOUR STUFF. You have a bunch of Components with no names. This is a simple
design but if you said to another Engineer I am having problems with my "Component 1" he will not have a clue what
you are talking about.
Cheers
