laptop for 3D modelling

[izio144]

Hi everybody, i'm looking for a new notebook.
I use some cad softwares (inventor, solidedge etc.) I want a pc that can support these softwares for some years. (now i have a 7 years old pc that can run they discreetly)
I shall carry the pc to the university, so i would a lite pc.
Now i've seen these:
Dell Inspiron 7000 15''
Dell XPS 15''
Msi (not a specific model)

You can racommend me other pc's?

Thank you and forgive me for the English (corrections are good accepted )

My work has HP Zbook 15's. Those are CAD grade stuff though they're pretty thick.
We also have HP 9480m's, which are really, really nice.

So, the former is quite expensive and the latter isn't available in my country ;(
