# Learn AutoCAD Basics: DAY 7

The present challenge is one of a kind. It is good to know that the objective is not only to be able to use AutoCAD commands but also to learn tricks and combine all the commands to get to the final image.

And one thing I will never mention enough is, there are often many ways to achieve a thing in AutoCAD. Use the idea that comes to you first if it does the job.

Simply remember to check your dimensions at the end of the exercise and make sure they match the ones mentioned in the image-exercise.

We will look a little deeper into the OFFSET command today. It is needed.

The OFFSET command helps create parallel lines and parallel curves.

If you have an object and want a similar parallel object to it, this command will be helpful.

To use the OFFSET command

1. Click on the OFFSET icon
2. Specify the OFFSET distance and Press Enter
3. Select object to OFFSET
4. Specify a point on side to OFFSET

The use of the ROTATE command will be required in this exercise, as well as the OFFSET command.

Below you will find diverse dimensions to help the replication of this session’s task.

## Execution

You need to start from the outer part of the object.

After getting the above figure done, OFFSET all circles with 10 units inwards, and OFFSET all line with 15 units inwards.

And you should end up here.

All you need to use the TRIM command and the FILLET command to get all done.

Sorry, When I said start with the 3 circles, I forgot to mention that, the circle of 120 of radius is coming before the two upper circles.

I see I see. I get it now. I have one more question, is the measurement of the top-left circle r20 and r10 instead of r25 and r15? because my r120 circle will always cross over the r25 circle.

Nope. It is just as you see. There is no mistake. U have to figure out a way to adjust them just as they are on the image. This is part of the learning process (This is part of the fun too)
