#### Lesson 11 - Drawing Splines

Splines were first develop to create smooth curves on ship hulls. nanoCAD also creates splines. In this video, you learn how to draw splines by two different methods -- fit and control points. You see how to edit splines with grips, and adjust their parameters with the Properties panel.

#### Lesson 9 - Drawing Rectangles & Regular Polygons

nanoCAD draws rectangles and regular polygons from polylines. In this video, you learn how to draw them by a variety of methods, as well as how to edit them using grips and the Properties panel.

#### Lesson 8 - Circles and Ellipses

In this video, you learn how to draw circles and ellipses by a variety of methods, and then how to edit them using grips and the Properties panel. The video include tips on how to turn circles into arcs, and arcs into circles.

#### Lesson 5 - Drawing Polylines

The line is the most basic CAD object, but polylines are possibly the most used ones. A polyline consists of one or more arcs and segments, like a single object. This tutorial shows you how to draw and edit  them. Special consideration is given to converting polylines to spline objects. Bonus tips show how to manipulate the spline, and how to turn a group of lines and arcs into polylines.

#### Lesson 4 - Drawing Arcs

Arcs may be the trickiest object to draw in CAD, and nanoCAD provides a dozen ways to do this. In this video, you learn how to draw and edit basic arcs, and then learn the differences between them. You also learn workarounds to drawing arcs in special circumstances.

#### Lesson 3 - Drawing Lines

The line is the most basic object drawn in CAD. In this video, you learn how to draw and edit lines as single objects and as rectangles. Special emphasis is placed on using drawing aids like object snaps, object tracking, and polar tracking, because these help you draw lines relative to other objects. You see how to draw lines with x,y coordinates and by using direct entry.
