I wanted to know if there is a way using Photoshop (2015).
What I want to do is to convert a selection to shape, actually I use the Polygonal Lasso tool to draw my shape, convert the selection to path and define the path to shape.
However this way I'll need to pick the shape from the mene and enter it again in the same position, I'd like to avoid this and have my shape already placed / sized when defined.
