1. Rectangular and Fillet
Draw a rectangular and fillet all four corners with a radius that is half the length of the small sides of the rectangular.For example, if you want to make an oval 120×50 then follow the next commands / inputs:
rec ¦ click a point for the lower left corner ¦ @120,50 ¦ f ¦ r ¦ 25 ¦ p ¦ click on any point on the perimeter of the rectangular
Your oval is ready!
2. Rectangular only
This is the fastest way! You just draw a rectangular and use its fillet parameter with the desired radius. The only disadvantage with this method is that the radius value you specified is now the default value for the next rectangular you will draw. So, in order to make a normal rectangular, you must change the radius parameter back to zero.
Again, if you want to make an oval 120×50 then follow the next commands / inputs:
rec ¦ f ¦ 25 ¦ click a point for the lower left corner ¦ @120,50
Your oval is ready!

3. Circles + Rectangular and Trim
The next method is not recommended because it's much more complex than the previous two, but it's always interesting and useful to know an alternative way to draw things in autocad.
Again, we have to draw the same oval as before 120×50. Draw a circle with radius 25 (half the length of the small side). Copy the circle by 70 to the right (or to the left, it doesn't matter). Number 70 derives from the length 120 minus 2×radius. So, we have 120 - (2×25) = 70. Next, draw a rectangular and snap the first corner to the bottom quadrant of the first circle and the second corner to the top quadrant of the second circle (the quadrant snap point must be enabled). Finally, trim every line there is inside your oval and your shape is ready.
p.s. If you need a closed shape (which is recommended), you have to Join the lines of your oval beacause with this method they are not connected. The sequence of the commands / inputs will be:
c ¦ click for the center of the circle ¦ 25 ¦ cp ¦ click on the circle ¦ move the mouse to the right (with ORTHO) and enter 70 ¦ rec ¦ click the two corners as described above ¦ tr ¦ enter to choose <select all> option ¦ select all four lines inside the oval
Your oval is ready (but keep in mind that the shape isn't closed).
