Option	Overview	Detail	Recommended Value
Topology		The shape of the polygons to be converted Tris (only triangular polygons) Quads (quadrangular and triangular polygons) Ngons (polygons with multiple sides, quadrangular, triangular polygons)
Density		This is the only value that automatically sets other values, so it's easy to achieve good results with this value alone. Lower the value: fewer polygons, rough shape conversion. Increase the value: more polygons, detailed shape conversion.
Min width	Minimum Size	Specify the minimum size of the polygons. To avoid congestion of small polygons, such as minute fillets, increase this value.
Max width	Maximum Size	Specify the maximum size of the polygons. To avoid extremely long or large polygons, decrease this value. To make the size of the polygons more uniform, decrease this value.
Surface plane tolerance	Maximum Allowable Deviation (in cm)	Specify the accuracy of the conversion. Lower the value: more polygons, detailed shape conversion. Increase the value: fewer polygons, rough shape conversion. Although less intuitive than Max width, this is one of the most common ways to increase or decrease the number of polygons.	A suitable value for low poly is 0.01, and for high poly is 0.0001. If you want to use a value smaller than 0.001, it may be better to decrease the Max width.
Surface angle tolerance	Maximum Allowable Angular Deviation (in radians)	Specify the accuracy of the surface conversion. Lower the value: the Curved surface is converted faithfully, and the number of polygons increases. Increase the value: the Curved surface is converted roughly, and the number of polygons decreases. This can be thought of as the minimum number of segments, or elements, per circle or cylinder.	A suitable value is 0.35 (for low poly) to 0.15 (for high poly).
Curve plane tolerance	Maximum Allowable Deviation of Edge (in cm)	Specify the accuracy of the conversion of the Edges and Face boundaries. This is similar to Surface plane tolerance, but affects the conversion of Edges and Face boundaries more than the center of the Face.
Curve angle tolerance	Maximum Allowable Angular Deviation of Edge (in radians)	Specify the accuracy of the conversion of the Edges of curved surfaces (boundaries of the Face). This is similar to Surface angle tolerance, but affects the conversion of Edges (boundaries of the Face) more than the center of the Face.	A suitable value is 0.35 (for low poly) to 0.15 (for high poly).
Curve max length	Maximum Allowable Length of Curve (Edge) Segment
Plane angle	Maximum Allowable Ratio between Plane Tolerance and Max Width	Useful for obtaining more quadrangles or polygons.
Inflect	Preserve surface quality	Add additional detail in areas where curved surfaces transition from convex to concave.
Simplify radial surfaces	Simplify radius geometry to improve overall edge flow.	Orient all surfaces - spheres, cylinders, tori, and cones - along a common axial direction. When the edge flow lines are aligned during faceting, simple radial geometry and blends line up more predictably.
Remove small features	Strip tiny surface details when exporting.	The option defines a bounding box threshold in the dialog. Any detail smaller than the specified size is omitted, making it ideal for high poly to low poly workflows.
Convex ngons only	Prevent creation of concave ngons for cleaner topology.	Available only when exporting ngons. It forces all exported ngons to be convex, inserting extra faces where necessary. This results in reliable topology and consistent normal shading in applications that don't support concave ngons, at the slight cost of a higher ngon count.
