Solidworks uses no RAM, why?

Hello,

we have a big Xeon Workstation with 128 GB RAM. If the Employee works on a Model (Sorry, Solid Works is not my Supportarea) the CPU goes on 100%

and from the RAM ist would be only used 2 or 2.5 GB. Meanwhile the 256GB SSD is FULL. Is the calculation ready, the HDD has 150 GB more space...

Graphic Card is a Quadro 6000. I think, the whole calculation (the Data) were outsourced on the SSD...We have a 24 GB RAM Notebook with Quardo 4000 and its faster....

Maybe someone can help me or bringe a solution approach?

Thank you very much.

Joe
