Geometry Creation Commands

In AutoCAD, you usually create 2D geometry to the precise size required. While creating sketches for part features in Autodesk Inventor, you often use 2D Sketch commands to create geometry quickly (with no regard to size). You then control the precise size and position by adding dimensional and geometric constraints.

This table compares AutoCAD Drawing commands to the corresponding Autodesk Inventor Sketch commands.

AutoCAD		Autodesk Inventor
	Line		Line
	Polyline		Line
	Polygon		Polygon
	Rectangle		Two point rectangle
	Arc		Three point arc
	Circle		Center point circle
	Spline		Spline
	Ellipse		Ellipse
	Point		Point, Center Point

In addition, some AutoCAD Drawing commands have corresponding Autodesk Inventor commands that can only be used when drawing a 2D sketch in a drawing file (IDW or DWG).
