Faceting & Stairstepping
Coarse Faceting (click to enlarge)
Coarse Faceting is almost always caused by an angle setting being too high, the deviation/chord height setting being too large, or a combination of both in this case the deviation is set to 0.05" with a 30 degree angle.
In the example, the cone apperas as though it has defined flats on it . The resulting prototype will build these flats on the surface of the cone resulting in a part that has flats on it instead of curved surfaces.
Standard Faceting is in between coarse faceting (with small file size) and fine faceting (with larger, unmanagable file size). Standard faceting is just detailed enough so that features build to the file dimensions, while being simple enough to maintain a manageable file size that can be easily traanfered over the internet.
In most cases, this can be obtained using .001” or .002” for deviation or chord height, and a angle setting of 10 degrees.

Fine Faceting is at the other extream of STL File Creation. It tends to produce larger files that are hard to transfer over the internet. Howe er for show models it is advisable to make arangments with your project manager to use these higer quality files.
