Why does the edge of my 3D Component look very rough?

VCarve is a Pixel-based Assembly program, which means all 3D shapes are approximated by square "pixels" with each pixel assigned a height.

When you zoom in along any edge of a 3D model, these pixels become apparent. However, if the edge becomes too jagged or pixelated, the Model Resolution offers some control as the higher the Model Resolution setting, the smaller the pixel size will be for the same material size and the finer an edge can be approximated.
