Is it possible to create mass on four springs (in Simscape Multibody software)?

TL;DR Summary

Mass on four springs (Simscape Multibody)

Dear Community,
I just started to master Simscape Multibody and at the moment I'm trying to simulate mass on four springs. However, when I build parallel connections, the program writes an error, for obvious reasons, because the mass is tied to the spring, and when the spring moves, the mass also moves. It is necessary to somehow fix the mass relative to the base and substitute four springs into its corners. I would appreciate any help on this issue. Is it really possible to do? Mass-damper system is implemented as follows:

Then I tried to add the spring into the corner of the mass, nothing worked of course. I understand that the approach is incorrect, but what is correct then...

Thank you

in advance!The correct approach to achieving what you are looking for is to use a rigid body rather than a mass. A rigid body acts like a fixed object, which means that when you connect the springs to it, the body will not move with the springs. To create a rigid body, use the Simscape Multibody Block Library and search for the Rigid Transform block. This block should provide the functionality you need.
