If you do an SVG export and you have used an unsupported effect that effect (and possibly a lot of your drawing!) gets rasterized and embedded as a base64 image
This means your vector drawing is locked into Corel Vector. Sometimes we need to be able to get it into a different app. If the SVG export had an option to not export the unsupported effects and export the objects they are attached to along with everything else we would be able to bring our drawing into any other application easily
