I bought this to replace my ancient w550s, which I adored. I mostly run solidworks and auto cad. It does handle those programs.I can’t express enough how much I dislike this laptop for two reasons. First, the keyboard and bottom half of the case feels CHEAP and poorly made.Beyond that, the touch pad is awful for cad work. Now I know other design engineers will laugh that I’m using a laptop for my work- I successfully used my old unit from the luxury of my couch while y’all are at a desk so there’s that.The touch pad is sticky and plastic feeling- tough to snap to nodes. My last laptop had the most silky smooth touch pad.If you can feel this laptop before cutting it I urge you to do that.
