MULTI CONSTRAINT PATTERN

Hi,

the green object has two constraint sets (1 and 2). I want that the pattern of the green object (1 green + 2 red), follow the first object (green) in his new set constraints (constraint set 2): what is the procedure to obtain this?

There are probably multiple ways to deal with this. If you were to add both sets of components to the assembly and then use a conditional relation (if then else) to determine which set is suppressed would that solve the issue. This would allow you to toggle between the two by changing a relation in the assembly.

 

Simplified reps may meet your needs and of course you could use an assembly family table to control which set is in each instance. Without context it is hard to say what would be best.

I am not clear on exactly what you need. Are you attempting to pattern the placement of assembly components in assembly mode? What version of Creo are you using?

 

 

The general approach to this type of pattern is to create a group that contains the elements to be driven by the pattern and then pattern the group. I am not sure this will work for your scenario as it looks like you would end up with overlapping instances of the red element.

Hi tbraxton,

I'm using CREO parametric 9 , in assembly design mode and I want that a pattern can stay in position 1 (contraint set 1 - green) OR position 2 (constraint set 2 - red).

I can do this by the flexible parameters in superior assembly, but I have to change every tyme the selected constraint set on every object of the pattern.

Is there a smarther method?

 

Thanks a lot

You can do this using pro program which needs additional licence but is only clean solution I know or family table I guess. You can also try this approach which is not exactly clean but it is straight forward and simple.
In assembly put in this code(change the distances by yourself)

if variant == 1
coord_x = 18
coord_y = 120
else
coord_x = 578
coord_y = 120
endif

and when constraining the main nut use parameters coord_x and coord_y.

Dont use hole references or point for patterns , This way you can swap it very fast
