[nik_9011]

After I Trace bitmap of my jpeg image part of it disappears?? I am tracing a stick figure hunter and his arms go away when I trace bitmap to save as svg...why is this? what am I doing wrong? TIA

Is your original image black and white, or is it colors or shades of gray? If your image isn't true black and white with no gray, you may need to adjust your trace threshold. The lighter the colors, the higher the threshold needs to be for a good trace. HTH
