Output 
Lets you select the type of element to be constructed:
 Mesh Element — The constructed element is placed in the design as a single mesh element.
 Shapes — The constructed element is placed in the design as polygons in a graphic group.

Chord 
If on, lets you define the maximum allowable distance from a constructed polygon to the original (curved) element it approximates. 
Angle 
If on, lets you define the maximum angle allowed between adjacent facets on a smooth surface. 
Max. Length 
If on, lets you define the maximum allowable edge length for any facet in the constructed element. 
Max. Num 
If on, lets you define the maximum number of edges for any facet in the constructed element. 
Hide Smooth Edges 
If on, smooth edges (interior edges between adjacent facets) in mesh element are not displayed. 
Normals 
If on, normal direction for facets is included in mesh element. 
Parameters 
If on, UV parameter at vertices are included in mesh element. 
Smooth Triangulation 
If on, meshes created from Bspline surface, planar shapes, complex shapes are triangulated smoothly. 
Keep Original 
If on, the original element is retained.
