I read this help page
So I created multiple curves for doing drawing with picture match (Btw, Use LayOut do picture match is much easier than SketchUp )
But they didn’t say how to fine-tune a axis of the curve
it always stick to grid or some alignment auxiliary lineline, I cannot done my work with this
I have been trying a while, but still cannot solve this problem, this is my first question in Sketch community
Please save me!!
