I need to know how to get the "New 3D extrusion from current selection" option/command to work. It is always grayed out/not highlighted and every tutorial I have looked at online, which I have followed correctly, still has shown no results. I was told my computer needed more ram in order for this function to work. If so, then how much total ram does my computer need? If not, how else to fix this problem? I need to do a 3D image for a future presentation and I want to do it, not give it to someone else to do it.
Your video card needs at least 512mb of VRAM.
