Merging Shapes to Create Gradient Icons in Sketch

Question

I've just started using Sketch and am aware that there are two ways to combine shapes:

1. Layer > Combine > Union
2. Layer > Covert to Outlines

I want to combine shapes to make one icon with one gradient across the shape. However, when I use either of these methods I can't achieve this.

When I use Layer > Combine > Union, the inner lines disappear.

When I use Layer > Covert to Outlines, the gradient is applied to each shape, not the shape as a whole (ex - fading smoothly from green to blue). This tells me that the shapes have not really merged into one shape.

Is there anyways I can combine the shapes to make one icon, and have a single gradient span across the icon?

Answer 1

So, this IS an interesting question :) I was able to do what you want, although I wouldn't say this is a rule, rather -- a workaround. Adobe Illustrator can handle this way better and faster, and I would recommend creating the icons there and then recoloring/using them in Sketch. Anyhow, here's my solution:

Note:

1. I am making sure no lines overlap (otherwise it will create holes in said locations).

2. Convert to outlines DOES NOT combine shapes on its own. It does what it says - it converts a line with thickness of 5px to a shape(rectangle) that is 5px high. Or a font becomes a bunch of shapes.
