Is there a way to flip an arc when you regenerate your part studio and the arc comes out backwards?

    To answer your question, no there is no "quick" way to fix that in a sketch.

    This is one of the reasons why (as a general rule, there are exceptions obviously…) it's better to leave sharp corners in sketches and use fillet features after the fact.

    Either mirror the entities and delete the old ones and reconstrain. or do this…

    which requires deleting 2 constraints and moving the center point of the arc.

    Would be a good idea to add an image to your question since the arc should not change. 🤔

    for example, if I have an arc with a fixed diameter and is tangent to two lines, when I regenerate it, It will flip.

    for example, this convex arc looks like this.

    When I Angle the are past 0 degrees, the arc goes all the way around, like this.

    I was wondering if there was a tool (other than manually deleting constraints and re constraining them) to flip the arc to make it like this:

    these all have the same constraints and dimensions, but are different.
