i am having trouble translating large files (35000- 50000 entities). these are surface and wireframe files. if i rotate or move the model it takes about 2-3 minutes. it starts out fast then slows down as it progresses. i have a pentium 4 1.8 133 bus speed 512 megs of ram 128 meg nvidia4 graphics card 7200 ata/133 hard drive i believe my computer is fast enough, so i thought it might be some setting i would have to change in mastercam. changing the file allocations on config screen didn't help. does anyone have any suggestions. thanks
