Study Notes
CIRCLE Command Options
- To specify the radius of a circle, enter values for the center location followed by the circle's radius.
- Create a circle with a diameter of 2.5 units using the Center, Diameter option; input the center point and the diameter value.
Tangent Circles
- The 2P (2 Point) option of the CIRCLE command creates a circle that is tangent to two existing objects.
- The point of tangency is where two tangent objects share contact.
Drawing Circles and Arcs
- To draw a circle that is tangent to three objects, select the 'Tan, Tan, Tan' option, highlight the objects, and select the tangency points.
- To draw an arc starting with a center point and a 60° included angle, choose 'Start, Center, Angle,' specify the start point, center point, and included angle.
Arc Definitions
- The included angle in an arc is the angle formed between the center, start point, and endpoint.
- The default prompt for the ARC command is to specify the start point or center of the arc.
Arc Commands and Options
- Three input options to draw an arc tangent to a previous arc include the Continuation Option.
Ellipse Details
- Ellipses consist of a Major Axis and Minor Axis.
- Drawing an ellipse using the Axis, End option involves specifying the endpoints for both axes.
Circle and Ellipse Properties
- A rotation angle of 0 degrees for an ELLIPSE results in a circle.
Polyline Creation
- A filled arrow can be drawn using the PLINE command by entering different starting and ending widths.
- The Halfwidth option allows width specification from the center to one side of a polyline.
Fill Mode and Polylines
- To turn off FILL mode, use the command 'FILL' or 'FILLMODE' with options to set it on or off.
- To create a polyline parallel to another, utilize the Length option with the PLINE command.
Shape Drawing Techniques
- To draw a hexagon measuring 4 (102 mm) across the flats, use the POLYGON command, select six sides, choose Circumscribed, then define the location and radius of 2 inches.
- Commands for creating rectangles include RECTANGLE, RECTANG, and REC.
Rectangle Features
- The Fillet command option allows for drawing rectangles with rounded corners.
- For a rectangle with specific line thickness, use the Width option.
Rotating and Solid Shapes
- To draw a rectangle at an angle, select the first corner and specify the desired rotation angle after activating the rectangle command.
- Create a solid circle by using the DOUNT command with an inside diameter of 0.
Spline Creation
- Use the SPLINE command to create a true spline and accept AutoCAD default tangents by simply selecting 'Enter.'
