I use the recent 2018 version of solidworks. I installed this on my laptop a Dell XPS 13 9370 (2018) modell. Some details: i7-8550U CPU, 16G RAM, Intel UHD 620 graphics and a 512G Nvme SSD. Funny part is that i was able to work with my sketches before. Since a few days SW crashes as soon i edit a sketch. The benchmark and all other so far i can see runs very smooth. My settings are defaults, i haven't set anything there. I hope someone has a hint for me how i can fix that really annoying behavior.
Please bear with me i am a bloody beginner and i am really well-set from the arguments of my VAR that i should stop playing and buy a training and a workstation who really can work. Thank you very much!
