Should I edit the parts LCS so that they are offsetted for parts to mate or should I offset stuff in assembly?
I usually try to set the LCS in the exact position where I want the bodies to mate as Zolko suggests. I use the body link attachment offset after assembly for minor adjustment such as adding clearances or making space for gaskets or such.
A cursory review of your file seems to show several discrepancies at least as far as the intended Assembly4 workflow.
A few brief comments:
1. After you first try Assembly4 (Asm4) a few times it may be useful to go back to the documentation and reread it to better understand the intended work flow. It sure helped me to do that several times.
2. Consider using a top level skeleton or master sketch for locating LCS's. The sketch can be used as an assembly solver. For example, you can set the diagonal tube angle by using the map mode such that the LCS points to the opposite vertex that it should connect to. That way you do not have to know the angle and it will update properly if the tube dimensions are changed on the master sketch. You do not have to use a master sketch with Asm4, but it can help you to slow down and plan the design before diving in.
3. Use the Asm4 workbench (rather than PartDesign) when creating a new body since it will provide you with a default LCS which can be used as the primary assembly interface for that body. When you double click the Asm4 body it will take you to PartDesign for creating the features. Add secondary LCS's for all the other bodies that interface with this body. The LCS should only be mapped to the sketches used to create the mating features for a more robust model.
4. Consider using the Asm4 Variables table rather than a spreadsheet unless your spreadsheet is quite complex. The variables in each of the linked files will be exposed in the Asm4 file with the linked body if the linked file includes an Asm4 Model.
Asm4 is more than a bottom-up assembly tool. It provides an infrastructure for top-down, in-context assembly design
with an integrated interface with the PartDesign workbench. Numerous real-life examples and brief comments on the work process are shown here which I hope are helpful:
