Using Drawing Aids
Scott Onstott · 2016
The drawing aids in the AutoCAD program are like the triangles, compasses, and engineering scales of traditional drafting. Drawing aids are essential modes and methods of entering data that, once mastered, allow readers to create measured drawings with ease. This chapter explains how to draw with Grid and Snap when readers' geometry conforms to a spatial grid, and how to use Ortho and Polar Tracking to draw horizontal, vertical, and angled lines. It then discusses how to use PolarSnap when angled lines are measured in set increments, and how to use running object snaps to save time connecting objects. The chapter also explores how to use the From snap to draw in relation to another object, and how to use object snap tracking to snap to points implied by the position of other snap points.
