Symmetry Relationship

Jimmy_Barrera

I'm trying to add a symmetrical relationship between two points (one on the left and one on the right) and a center line in my sketch, but I don't see a Symmetrical Relationship button. Is this in the works...or did I overlook something?

Paul Arner

have you looked for mirror? (Towards the center of the toolbar menu in sketch)

that's because there is no symmetry con taint - along with Pierce Constraint (both greatly needed) - and mirror sketch geometry is not a substitute - unless it actually works that way (mirror doubles as a symmetry constraint.)

You are correct. Mirror copies the geometry across the mirror line and creates symmetry constraints in the process. Once the process completes, the symmetry constraint remains to enforce the mirror-like behavior. So in your example, create a single point and a line of symmetry, and then mirror the point about the line and I think this will give you what you wanted.

Paul Arner

The issue is that we make some assumptions about the geometry on both sides of the symmetry constraint which are difficult to ensure if the user were to be able to create the constraint himself (mostly for more complex geometry).

I have logged a ticket and improvement for this @Jbarrera_CQ‌ If there are others, let me know.
