Partial shape subtracting only

Question

Im trying to make some dice but one of the shapes is not subtracting from the cube properly. The sun on the right side is only partially subtracting.

I started with some svg vector saved from inkscape, imported and then extruded them. My plan was to subtract.

Any help?

Edit:

Sorry I never Checked my Curves from Inkscape properly. I had some unlinked shapes. I would have thought that blender would say. "Yo, dude... your vector sux"

One of the vector files I saved out from Inkscape had some duplicate nodes that were not linked.

I went back into Inkscape and tidied up the vectors and made sure the shapes were full complete enclosed shapes with no duplicate nodes

In theory, this should work. Upload your blend file to blend-exchange.giantcowfilms.com so we can take a look. — Leander, Oct 08 '16 at 11:36
if booleans act weirdly, the problem is usually always on normals (all should point outside), but also check before that you have not a negative scale... that would invert normal visualization... — m.ardito, Oct 08 '16 at 17:57
@m.ardito I'm not sure what negative scaling is. I have been googling it still seeing if i can figure it out. I have Checked the normal's of the sun all the lines point outside. Although all the normal's of the cube were pointing inside. I had to Mesh > Normal's > Recalculate Inside to get them pointing out.... howver this still does not work. — zenril, Oct 09 '16 at 08:01
Sorry, I meant: in Blender you can set scale to -1. It makes no sense to me, but it is possible and can happen by mistake. When you do that, normals that visually seem to point "outside", are really pointing "inside" (due to negative scaling), thus what you see is wrong, and booleans logic is inverted... — m.ardito, Oct 10 '16 at 08:23

I think I found the problem with that boolean: duplicate vertices!

I've hidden other shapes, to better see the two objects involved by the boolean, and here is you wrong result:

then I selected the "sun" shape, in edit mode and removed duplicates

It had 78 duplicate vertices:

And, after that, the shape works better with booleans...
