Ключевые преимущества параметрического моделирования
Now that we have our cylinders bored out we will take a second to see one of the advantages of this system. Suppose at some point in the development, we find out that we want the cylinders to be a bit bigger. Since the union and intersection operations we performed were recorded as groupings in the tree view, we can change the cylinder size and FreeCAD will just re-run the union and intersection process and arrive at the new engine size. Play around with the radius and position of the two cylinders a bit and then return them to the parameters quoted above, before continuing the tutorial.
