Translations:Engine Block Tutorial/16/en

Now that both cylinders are in place we want to use them to bore out the block to the appropriate dimensions. To do this we will use boolean operations on our 3 primitives. We will start by making a union out of the two cylinders so we can subtract them as a group from the block. Select Cylinder 1 in the tree view and then +LeftClick to select Cylinder 2 as well. Now press the Union button to fuse the objects together. You will notice that in the tree view, there is now a new object called Fusion. If you click the dropdown arrow next to Fusion you will see the two cylinders but they will be grayed out. Instead of Fusion, lets rename that to Cylinders so it is easier to find later. Now we bore out the engine block. Select the Billet and then select the Cylinders and press the Make Cut button. The two selected objects will again be combined like they were for the union operation and the single resulting object will be named Cut (which you should rename to Bored Block). Press the 2 key on the number pad and you should now be able to look straight down through the cylinders out the other side of the engine block, then MiddleClick+LeftClick+Drag to look at your engine block. To the right you will see what the finished product should look like, notice that I have expanded the tree view on the left to show the individual primitives and have selected Cylinder 2 for examination in the Data tab of the Property View.
