Can anyone provide suggestions for optimal settings in AutoSketch within SolidWorks to improve the accuracy of autotraced sketches?

I am currently using AutoSketch within SolidWorks to generate sketches, but I'm having difficulty obtaining exact sketches. Despite my best efforts, the sketches I obtain are often not accurate, which is problematic when it comes to creating 3D models. I've noticed that the autotraced sketches I generate are particularly inaccurate.
I suspect that the issue may be with my image settings, specifically the brightness, contrast, color, and recognition tolerance. I'm hoping to obtain some suggestions for optimal settings in these areas to help me generate more precise and accurate autotraced sketches.
What are the best image brightness, contrast, color, and recognition tolerance settings to obtain precise and accurate sketches?
