All here is a déjà-vu. In the last session, we’ve learned how to use the ELLIPSE command in AutoCAD, in this session we are coming back with an even easier ellipse.
BUT, but now, the focus will be made on something totally different.
in Learn-AutoCAD-DAY-6, we have worked with the ARRAY command for the first time. Today you will need that command line more than EVER. And it is compulsory to have mastered it before trying the coming exercise.
Learning AutoCAD Basics
NOTE: Element in the array are equally spaced around the ellipse.
Figure 1
Figure 2
In the following image, the red line represents the PATH of the array. It resulted in an OFFSET of 5 units from the outer ellipse. You can check how you can construct such an ARRAY here.

Objects in the array
The object in the array is nothing but the following
You can find the dimension of the circles on the first image above.
Execution
The only thing that might be hard to accomplish here is the array. There is nothing like ARRAYELLIPSE in AutoCAD, what you need to do to create this array is using the ARRAYPATH.
To use the ARRAYPATH command using an ELLIPSE, you need to cut the ellipse into two and use the ARRAYPATH on each of the sides, that is it.
We would like to let you fight with it and figure it out yourself, using the information we provided above.

I struggled on the center area with the three radius. Right click the ark and convert spline to poly line. Then use a circle with tan, tan, radius. Trim as needed.
i can’t fillet line and the circle at R=2

Thank you so much, buddy. I also got stuck at the same point. Thanks for your guided images.
Find a way around it. You have done the most difficult part to be not able to do it.
