Rhino can place a bitmap image into each view of your model project. This can be used as a guide for constructing the lines, surfaces and solids that make up your model. It is important that these various images are scaled to match each other, and located in space so they all line up. Usually 3 views, one from above, one from a side and one from the front are used, together with a perspective view of the model. Our bitmap images will be placed on the x, y and z axes, with the centre lines lined up with the axes. Imagine 3 pieces of cardboard slotted together, each with one of our images printed on it.
