Hello curtie, I have done your drawing without real problems. 
I had to use the UCS command to draw correctly the ellipses ( each one individually and not the second with the offset command to have 2 real ellipses ).
I had to use the offset command to draw the radiuses R34 and R45 because tangancy doesn't works on ellipses.
Is it that you see the centerlines continuous ( use the LTSCALE command to set the visibility ) or you don't succed in drawing the 2 centerlines of the ellipses ( draw a vertical line at 68 mm from the right line of 68 mm and rotate ir by 30Â°, then offset the horizontal centerline of 241 mm by 146 mm and you will get the center of the ellipses at the intersection.
I suppose that the drawing that you have uploaded is a paper and that you want to draw it on AutoCAD !
Instead, upload an AutoCAD copy of your test.

	Hi guys I'm struggling with this drawing, the drawing is in mm and i don't know how to get the center line on the vertical line. The measurement is 146mm from the horizontal center line. Please help. uploads/380818/IMG_20130606_0002.pdf
