Translations:Engine Block Tutorial/57/en

Now that we have 3D objects for the bore holes and the outer shape, we can use a few boolean operations to stitch the whole thing together. Select your 6 extruded head bolts in the tree view and join them into a union (name the resulting object Head bolt boreholes). Then select the Bored block and the Head bolt boreholes in that order and perform a cut (like you did when you bored out the cylinders), name the resulting Cut object Block with headbolts. Finally, select the Block with headbolts and the Extruded spline and press the Make intersection button, and name the resulting object Engine block.
