This document provides instructions for a 100 point assignment on mapping techniques, including making a cross section from a topographic map, drawing outcrop patterns of horizontal, vertical, and tilted planes on a topo map, estimating the area of an irregular solid, calculating the volume of a tilted layer confined in a box, determining the strike and dip of a plane using three points, identifying parts of a Brunton compass, and finding the strike and dip of a plane with a Brunton compass. The instructions emphasize that submissions must be handwritten, include illustrations, and show step-by-step work to receive full credit. Incomplete or typewritten submissions will receive few points.
Evaluators provide a way to specify points on a curve or surface (or part of one) using only the control points. The curve or surface can then be rendered at any precision. In addition, normal vectors can be calculated for surfaces automatically. You can use the points generated by an evaluator in many ways - to draw dots where the surface would be, to draw a wireframe version of the surface, or to draw a fully lighted, shaded, and even textured version.

Reminders
Incomplete submissions can only get a maximum grade of 30/100
must be HANDWRITTEN (typewritten submissions will get an automatic grade of zero (0/100)
all figures must be hand drawn or sketched except for topo maps and brunton compasses (all
other markings such as construction lines or planes must be sketched. (noncompliance = 0/100)
