Khi bạn chọn một màu sắc và kích một nhóm hoặc một thành phần, bạn vẽ tất cả các khuôn mặt của nhóm mà có màu sắc mặc định. Nếu bất kỳ khuôn mặt đã được sơn, hoặc từ trước khi nhóm đã được tạo ra hoặc khi đã được chỉnh sửa, áp dụng một màu sắc toàn cầu để cả nhóm sẽ không ảnh hưởng đến những khuôn mặt. | Figure 3-21 Figure 3-22 Painting Groups and Components When you pick a color and click a group or component you paint all faces of the group that have the default color. If any faces are already painted either from before the group was created or when the group was edited applying a global color to the whole group won t affect those faces. Painting a group like this has two advantages It s quick one click and both front and back faces get painted. This is helpful when using a group or component for cutting because you can easily identify its faces after the cutting is complete. All of this is shown in detail in Recipe . Figure 3-23 Figure 3-24 6. Select everything right-click on any selected object and choose IntersectwIntersect with Model. You now have edges along each vertical face Figure 3-21 . 7. Erase the groups and your intersection edges remain as shown in Figure 3-22. 8. Erase the peak face within each vertical face and you have just holes and edges Figure 3-23 . Those edges are the where the cutout groups intersected each other. This looks nice but there are no passageways. To make the passageways you need to keep a portion of each cutting group which will provide the necessary faces within the gazebo. 9. Choose Undo to bring back the three groups and be sure to keep the intersection edges. 10. Because you need to keep portions of each group the groups need to be exploded or ungrouped. Select all three groups right-click on one of them and choose Explode from the pop-up menu. 11. You can t erase each group with one click anymore but you can remove the parts that stick out. Do this in Top view using several right-to-left selection windows. This is easy when the faces protrude far enough from the gazebo. 12. Erase one of the front peak faces and this time you can see portions of the cutting groups running through the building Figure 3-24 . Using Groups or Components to Create Cutting Objects 61 13. Remove all of the faces inside the passageway so that you
