Dear friends,

It is possible to draw the figure below by using only the CIRCLE command and a few editing commands. Drawing the figure together, you are going to learn how to use the CIRCLE command.

The techincal figure of the object to be drawn

Let us start with the holes with the radiuses of 3.34 units: The easiest way of drawing a circle is entering a center point and a radius. Pick a point for the center and draw a circle with a radius of 3.34 units.

Command: _CIRCLE
CIRCLE Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:
Specify radius of circle or [Diameter]: 3.337

Copy the circle 35 units horizontally.

Figure.1

Then, draw two circles with radiuses of 5 units using the same center points.

Figure.2

Now, we are going to draw a circle with a radius of 50 units using ‘ttr’ option (i.e. Tangent, Tangent, Radius; tangent to two circles and a defined radius). The command proceeds as below.

Command: _CIRCLE
CIRCLE Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: ttr

Specify point on object for first tangent of circle:
Specify point on object for second tangent of circle:
Specify radius of circle <5.00>: 50

Figure.3

Clip the extra parts of the circle drawn lastly by using TRIM command.

Figure.4

MIRROR the arc left to the opposite side. And it is done (Figure 4).

I am going to mention other features of the CIRCLE command in my other articles.

Regards.
