The image of drawing is attached below.
I'm trying to make this engineering drawing but I am not able to make the left side of top view of the drawing.
To me, it seems like some dimensions are missing to draw arcs.
Could someone try to make it and share a video tutorial?
Thanks a lot.
Layout the guideline geometry from the given dimensions and draw the final lines. All the information is in the sketch.
some math: R38 + R24 = R62 for the center of the 50 degree arc.
R13 is fillet of the two straight lines
please check the screenshot below, the angle which I highlighted should be of 50 degrees.
And i have also shared my own drawing, could you explain how you plotted 2nd arc
Thanks
I have made it this far.
I still can not understand that math. could you please elaborate

The opposite is the case: If we assume on the left site all arcs/lines touch tangetially, then one of the dimesnions (e.g. the 50° angle) leads to an overdimensioned/overconstrained geometry.
Attached an example which was drawn using constraints. I "ignored" the 50° angle and got an full constrained geometry.
I you move the inserted image 200 to the right you can compare you image shape with the AutoCAD geometry. To reduce the discrepancies between both I changed the 96 dimension t0 95.
You can play with this file until you get the needed result, as example:
- change the 95 back to the initial 96 (double click at d6 and change the value) and see what happens
- add the 50° angle if you urgently need that value (you must delete one of the tangential constraints before) and see what happens.
- Play with changing other dimensions and or geometrical constraints. We (I) can not know how the shape should look at the end.

Thanks to the others it looks like you have a solution. I didn't catch the 50 degrees earlier as I had to get to work.
But the question I have now is if that is top and front view, why is the front view wider than the top view?
