Arc

An arc is really nothing more than a portion of a circle, so drafting one is very similar to drawing circles. The biggest difference is that instead of just defining the radial size of an arc, you also need to define where the arc starts and ends. You can execute the Arc command from a toolbar or by typing “arc” at the command line. Auto CAD provides many different options for defining your arc, which you can examine in detail through their help utility. Below, I’ve listed the four most commonly used methods of arc creation, and given a graphic example of each in the example above. The various options can be accessed through the pull down menus or by selecting the appropriate options from the command line as shown above.

3 Point Acr

Three Point Arc (3P):

This is the simplest way to draw an arc but it’s also the least exact from a drafting standpoint. You simply select the start, midpoint and endpoint of the arc on screen.

Start, Center, End

Start-Center-End:

This works similarly to the Start-End-Radius command above, but you select the center point of the arc on screen instead of typing a radius.

Start, End, Angle

Start-End-Angle:

This method is the one of most commonly used. You select the start and End of the arc on screen, and then you can give angle of arc to complete the arc.

Start , Center, Length

Start-Center-Length:

Allows you to pick the start and the center point of your arc, and then complete it by entering the linear distance between the start and end points.

Start-End-Radius:

This method is the one most commonly used. You select the Start and End of the arc on screen, and then you can either drag the cross hairs or type an exact radius to complete the arc.

Start-End-Direction:

This method is the one of most commonly used. You select the start and End of the arc on screen, and then you can give direction left, right or top, bottom to complete the arc.

Ellipse

Two axis values are required for an ellipse. Ellipses can be regarded as what is seen when a circle is viewed form directly in front of the circle. Ellipse is measured in terms of two axes there are major axis and minor axis. You can draw ellipse in various way such as using axis, end option or center option.

Ellipse

 

Draw procedure of ellipse:

Command: Ellipse

Specify axis end point of ellipse

Specify other end point of axis (Say essential dimension) 8

Specify distance to other axis (Say essential dimension) 8

Hatch

Hatch Command

Boundary Hatch by typing H <ENTER> .

When you start the command, you will see this dialog box appear:

Swatch

  • Now you want to pick the area to be hatched swatch box.

Select Hatch

  • Pick somewhere when hatch pattern plate say (ANSI, Other Predefined, ISO)

Select preview for the hatch are OK but when we do not see hatch so set the scale of the hatch and then finally, see the Preview button to see if this is what you are after, it should match your desire work.

Note: When hatch pattern does not match your work what can do you?

Hatch Edit
