Mirroring an arbitrary vector for symmetry in Sketch
I'm trying to convert a raster logo to vector using Sketch. I've traced out part of the logo with an open vector, but only one-half of it. Now I want to mirror (flip horizontally) a copy of that open path, and join the two points. Here's the left half:
I copy and paste that, then flip the copy horizontally (I wish there was a mirror-across-axis feature). Then I drag it horizontally (with shift held down) until the left edge of the copy snaps to the right edge of the original. When this is done, the copy is 1/3 of a pixel lower than the original.
I can't figure out another way to accomplish this. Any suggestions? Thanks!
It seems the solution for your problem is in this answer:
Go to sketch > preferences (on a mac press CMD + ,), and under the first tab (General), uncheck the first box (says "Pixel fitting: Fit layers and points to pixel bounds").
This will allow your objects to align properly when mirroring.
