If you’re working with an existing model, you can always use the Axes tool to realign your axes if you need to. If you’re not using a common reference point for the origin, scaling becomes more tedious because you have to go back and forth between scaling and moving the origin until you get the alignment right. This not only makes initial alignment super straightforward, but it also makes it really easy to scale the model because everything scales away from the origin. When creating this basic shape, the axes origin in the model and the origin point you chose in the photo should be in the same place. So if you are using Match Photo on a building, you should at least model a cube, and one of the sides of the cube should be dimensioned accurately to a known dimension on the building. You should create some reference geometry in your model to help you align and scale the model while configuring match photo. This is the step that most people skip when using Match Photo, but it makes the process so much easier, and much more accurate. You must login to download Setting up your model for Match Photo So for this photo, my origin point would be this bottom outside corner of the building. We do this because the reference grid projects away from the origin, so aligning the origin correctly will make the reference grid align with the three planes in the photo. This point should be where the 3 planes intersect, depending upon which perspective your photo was taken from. Once you have a photo chosen for your Match Photo, identify a point in the photo that will represent the axes origin. Each one will get saved in a scene, which can be recalled at any time. TIP: You can create as many Match Photos as you want in your model. The last step to creating a Match Photo is to scale the model, so having some reference of the size of an object in your photo will make this task much more accurate compared to simply guessing.
