We hope your assessing skill has improved, meaning you are more able to judge the difficulty of an exercise just by looking at it.

In this post, we are going to keep on using basic AutoCAD commands and focus more on how to combine their use to accomplish a specific task.

LEARNING AUTOCAD BASICS

The following are the images we are going to be using today.

EXECUTION

Start by creating the following.

The first object you should create is the red circle. Then make sure the QUADRANT mode is activated in the Object snap settings, this will help you snap the center of those big circles at the point A.

(Right click on 1 and tick 2)

After proper trimming you will end up with the following image

Use the OFFSET command on the red part to obtain the following. OFFSET distance = 12.5 units

Draw a line from the two openings of the object, and create a circle using the middle point B of the line you have just created.

We have not talked about the small circles 30 and 60 degrees away from the vertical. Using techniques we have used to create objects in previous DAYS, those should not be a problem.
