Changing Geometry Settings The 3D Effects Options dialog box allows you to control the geometric properties of entities during an extrusion, including how closed entities are displayed, and whether text, symbols and groups are exploded or ignored during an extrusion. Another control allows you to determine how finely arcs, circles, or curves are drawn when converted for extrusion. s When the Cap Closed Entities check box is checked, AutoSketch treats the original closed entity, such as a circle, as a polygon during an extrusion. s When the AutoExplode Text check box is checked, AutoSketch automatically explodes text to polylines or polygons during an extrusion. If this box is unchecked, AutoSketch ignores text during an extrusion or perspective operation. s When the AutoExplode Symbols/Groups check box is checked, AutoSketch automatically explodes symbols and groups to base entities during an extrusion. If this box is unchecked, AutoSketch ignores symbols or groups during an extrusion. s The Conversion Quality drop-down list box controls the number of vertices (and consequently the number of connecting lines or polygons) that are created when an arc, circle, or curve is converted to a polygon during an extrusion.
