How SketchUp quickly draws a building fence model

So far, sketchup parametric modeling can be the fastest method. First, we need to create the pb3 components of the fence for use. Next, we call the components into the model and create them all the way according to the outline. Once you are familiar with the modeling of using pb3 With this method, you can create your idealized fence style arbitrarily, which can improve the modeling efficiency several times for repeated large-scale modeling.
