Intro: My Colleague and I have been using altium Designer for Sometime now . Currently AD 17.1.6 (build 538) . The PCB we draw are 3d 4 layer maximum . the only difference between us is that the smallest grid I use is 0.1mm , while he uses the finest Grid 0.025mm.
Problem: when my Colleague is using Design Rule check it is taking for every to be done ( about 30 minutes ) . while my PCB which is comparable in number of components nad size takes about 30 seconds on the same Computer !!
My thoughts: I am trying to analyze the problem and i have come up with 2 possible causes :
The Fine Grid is causing the program to make more calculations causing it to take more time , can anyone confirm/comment on that ??
The 3D objects placement and clearance is causing the software to consume the extra time (unlikely) , but does anyone know a way to prevent the DRC from looking for violations in certain rules ? so i can go one by one and eliminate until i find most time consuming rule.
If anyone is wondering about the PC : it is a core i5 processor, with 8Gb ram and GTX 660Ti VGA.
