Chris if all conditions are met but flipping still happens what can then be done ?
You mentioned it is that silver issue.

Re: Sketch on body face flipping problem
Three techniques:
- Angles are more robust against flipping than horizontal/vertical constraints.
- Expressions make sketches very robust.
- Change the solver.

Re: Sketch on body face flipping problem
* Ctrl+Z is very helpfull
* it's possible to help the sketcher solver by moving lines by hand the closest from their final position, before adding more constraints.

Re: Sketch on body face flipping problem
I am not really surprised by the behaviour. If the angle of the construction line is <= 90° it is oriented to one side, if it is >90° it is oriented to the other side - as if the attached coordinate system has some weight on one side.
I attach the file, because it is fully constrained and has thus nothing arbitrary. To reproduce you have to change only the angle Constraint6.- Attachments
