Nice work! Really well made pictures.
@Howil maybe https://forum.freecadweb.org/viewtopic.php?f=10&t=34586 ?
Yes it was, but the file has grown to 16.1 Mb after completing two of the six geared links. With the .stl files stripped it is 14.5 Mb.
Do you know the "Mesh Remodel workbench" ? Maybe it is helpful.
Can you please elaborate on why you use ASM4? Never used it until now but I would have used ASM3 without thoughts.
Only vaguely, but it looks like it should be helpful for reverse engineering .stl files. Almost like cheating, but thank you for reminding me for next time.
I think I understand why the bevel gear changes position when the gear parameters are changed as it should for normal usage. In my case, the gears are not meshed in a normal manner. A PartDesign > Clone solved the problem nicely since it has independent placement and retains its link to the gear parameters.
Assembly4 facilitates my modelling process of in-context, top-down, mastersketch-driven assembly design that I have used since V0.13. Also, it is quite simple to use and meets 90% of my needs including animation of articulating mechanisms using the sketcher solver. Once Assembly3 is added as a standard workbench I may look into it for those 10% of cases that ASM4 can't solve. I do not know yet if ASM4 can articulate the CV joint so may need ASM3 sooner than later.
