How to fully define this 3D sketch?
I replicated your sketch but without the planes. I also couldn't quite make out the last length (right) so I made it 60MM.
I had no problems at all with it being fully defined. I have attached my file for you to look at (2016 SP3) You may need the planes for a specific reason, if so, you could still add them using sketch references.
Hope this helps.
Start with basics, try dimensioning anything blue again, start with the straight lines. You will also note that your blue corner arcs (furthest right) show no radius.
Whatever dimension I gave it became like this.
I actually meant these corner arcs........
Result is same.
That's because it's over-defining it now........
Can you try and fully define these two points on Plane 3 ?????
I wish to know whether this can be any use if line is not along X, Y, or Z axis.
I never add relations in that manner Maha.
To fully define your sketch:
I first added 3 construction lines to the midpoints of your 3 lines (yellow arrows).
Second I added the 50 dimension to the middle construction line (green arrow)
Third, because this new dimension over-defined the sketch, I deleted the front 50 dimension (red arrow)
Actually, because this is a thin part, my approach would have been to do those 3 construction lines as solid lines in a new sketch (on the front plane). Then add a sketch fillet and do a thin mid-plane extrude. Then fillet the solid corners.
