Hi, I am a teacher at a public middle school. We are working on an enrichment program where students are printing off a 3D grid square of a local mountain so that all the squares fit together ultimately making a 3D topographical map puzzle. Unfortunately we have a small hangup, when we made the images in google drawing we used more than one line, now when we import it into our 3D program it either shows up as an outline only (and we can’t figure out how to fill it in), or it looks like nonsense (when a scribble line fills in part on one side part on the other based on where it started and stops). How can we take our SVG files and keep them as vector images, but make them be seen by software as one thing rather than lines next to one another. All of our images are closed shapes. Please help.
