Can someone explain or point me to a resource that explains DXF's. Frankly I don't get it. I recently downlowaded some dxf models and one ( a can,i.e a simple cylinder) was more than a meg. I know OBJ's come with texture maps but DXF's don't? Is this right? If so why is that simple cylnder model so big? As long as I am confessing my ignorance, what is the deal with DXF blocks and layers? As you can see, I need help...and anyone that might offer some would be greatly appreciated. dxf mode
