Equivalent Damping: C1, C2, C3 in Parallel?

[Tekneek]

In this damping system it is obvious that the dampers C1 and C2 are in parallel. But I don't understand how "noting the location of force" in this system tells us dampers C1+C2 are in parallel with damper C3. Any help will be appreciated. Thnx

Component layout on the page is arbitrary. Mostly it's about esthetic values for presentation!

Flip C3 to the left hand side of the vertical line in the center (maintain the same component connections). What do you see now?

To the OP: In following gneill's advice, it might be useful to try and convince yourself why flipping C3 doesn't change the system behavior.

They are in parallel because they have the same velocity. Same case if they were springs, the displacement would be the same.
