I'm attempting to assign a Bearing in an upper level assembly.
The way it works is as such:
Top_Level.ASM
Top_Level_Motion_Skeleton.ASM
Top_Level_Skeleton.PRT
Top_Level_Ground_Body.PRT
Top_Level_Input_Shaft_Body.PRT
Top_Level_Output_Shaft_Body.PRT
Input_Shaft.PRT Associated to Top_Level_Input_Shaft_Body.PRT
Input_Bearing.ASM MY QUESTION IS HERE
Input_Bearing_Motion_Skeleton.ASM
Input_Bearing_Skeleton.PRT
Input_Bearing_Ground_Body.PRT
Input_Bearing_Inner_Race_Body.PRT
Input_Bearing_Carrier_Body.PRT
Input_Bearing_Outer_Race.PRT
Input_Bearing_Inner_Race.PRT
Input_Bearing_Carrier.ASM Associated to Input_Bearing_Carrier_Body.PRT
Input_Bearing_Carrier_Motion_Skeleton.ASM
Input_Bearing_Carrier_Skeleton.PRT
Input_Bearing_Carrier_Ground_Body.PRT
Input_Bearing_Carrier_Carrier_Body.PRT
Input_Bearing_Carrier_Ball_Body.PRT Each ball has its own body and its own rotational axis
Output_Shaft.PRT
What I want to do is truly be able to complete this assembly with top down design methodology, but I am having trouble. When I try to assign the bearing to the upper level assembly, I need to assign it to both a rotating and fixed body. The rest of the motion is controlled by the gear pairings I have created.
Where I am having trouble is trying to use coordinate systems to define the body pairings. I have created coordinate systems in the Top level Motion Skeleton Bodies, and in the bearing bodies, but when I try to assign one part using multiple coordinate systems, it works at first. Then one or the other coordinate system takes over, and when I try to edit the placement, the program states that I have invalid assignments.
As I missing something here, or is this a limitation of the program to allow the assignment of two coordinate systems?
