I often manage company layouts with DXFs of the line (top view) reported on a sketch and constraining the 3D of the details themselves

With very complex DXFs, usually from 5000 lines onwards the management becomes particularly difficult (selecting all the lines, copying them, scaling them etc.) SOLIDWORKS often gives the warning of not responding or is very jerky; this loading problem persists for the entire duration of the LAYOUT 8 processing (not only when opening the file together).

The same problem arises during the machinery constraint phase, as the file size is about 70/80 mb of STEP files (often they have many faces and surfaces being complete company machinery), the details are jerky, even the cursor, the loadings are long and it becomes difficult to work.

Going to the task manager during work and during the phases in which SOLIDWORKS freezes, the CPU works at about 20%, the RAM at 60% and the GPU at 25%, the temperature always remains at 60°

The technical specifications of the PC are: i7 7700 16GB RAM Quadro P2000 SSD 500GB

The PC settings are not set to energy saving as the display settings of soliworks are set to + fast and there are no other applications open on the PC except Chrome

If you have any advice to make everything go smoother and faster, thank you.
