FYI - The drawing was solved at another website, by more than one person, using the exact information provided by the OP and without the use of constraints.

Yes John You can use geometry only + the command ALIGN to place the little lateral R1.00 arc.

The ALIGN command is not necessary to complete the task.

Hello dery and John, I'm so sorry for the delay and I did erase the "align" phase but that 10° rotated drawing nearly worried me more than the rest and I still have some "real" work here ( at work).

The 10 deg rotation means nothing you could easily have rotated the drawing an additional 80 degrees (to a full 90) and it would not have any bearing on the solution.  Why do people seem to all but ignore the words "symmetry centerline"?  You could solve for half the drawing then mirror the solution for the other half.

Yes John of course I did use the symmetry for the drawing and I could also have rotated the entire drawing at the last minute...

I can't download the .dwg file. The link says 404 not found error . Please upload it again. Also, what is lateral?

OK dery I can't download the file too, I'll put it in the CAD/BIM Blocks tomorrow.
There are 2 radius R1.000, 1 on the centerline and 1 on each side of the centerline.
THE problem of the drawing is to achieve those 2 lateral radius R1.000 and still have the tangent between all the radius.

Hello dery, please find here in the site at CAD/BIM Blocks the file : Arc2-PJH-03.dwg
Do re-draw the entire thing using complete circles + circles intersections, lines, etc...
Please see and read all the here under Related CAD tips: Tip 2060: How to draw an arc with.......
Please take a look on the internet at : AutoCAD Tutorial lessons.
