numsegments = integer

Specifies the number of copies of the original 2-D object to appear in the extrusion.

The extrude command takes a 2-D plot object and generates a 3-D plot in which the original object is extruded along a path specified by transform.

The path parameter transform is a mapping of the form $\left(x\,y\,t\right)\mapsto \left[f\left(x\,y\,t\right)\,g\left(x\,y\,t\right)\,h\left(x\,y\,t\right)\right]$ in which x and y are the coordinates of a point in the original 2-D object and t is the extrusion parameter, sampled from erange. The default value for transform is the identity function, which corresponds to a uniform extrusion of the original plot in the z direction over the interval specified by erange.

In the case when erange is a range, the numsegments option specifies the number of sample points over this range and therefore the number of copies of the original object that should appear in the extrusion.

The plottools[extrude] command was introduced in Maple 18.
