first off my apologies for my poor english.
I'm tying to learn a better way to recreate automatically this square frame shown on the left of this picture (1) so I can use it for irregular shapes in the future (3). Notice that inner and outer corners of the frame are straight (2).
I did this first frame with two layers one ontop of the other. The one on top had a white fill and was slightly smaller in size, the one below was red (with a red fill too) with a Bevel & Emboss effect. Putting the smaller white fill layer on top would conceal the layer below except from its bevel border, creating the illusion of an empty frame. This, however, only works for rectangular shapes.
So next I thought I'd could try to combine paths to get the frame shape (4). But then, when I applied the Bevel & Emboss effect to the whole layer, the result I got was (5). You can see the inner corner of the bevel is rounded (6). And keeps round no matter how much I change the size of the inner path.
I kept playing with different Path Operations like Substract Front Shape and Exclude Overlapping Shape but got same result every time.
How can one substract front shapes with a Bevel & Emboss effect and get a inner sharp edge like in (2) instead of a round inner corner like in (6)?
Thank you for your time!
