How to remove segments of objects from carbide create library items

I’ve been trying to edit out part of a heart outline from a carbide create library image.
i can’t remove any part of the outline that isn’t within the size of my stock.

Is the geometry in question magenta or black? (when not selected)

For the latter see:

Can't wrap my mind around 3d modeling

Can anyone help me out with the 3d feature of CC pro. I have a simple SVG of linked hearts that I want to be raised out of a sign I am making for a friend. But I can’t seem to figure out the settings. Anyone point me in the right direction? [interlocking-hearts]
