Lợi thế để thực hiện một kết cấu độc đáo mà bạn có thể thêm chi tiết cho một khuôn mặt cụ thể mà không cần thay đổi tất cả phải đối mặt với cùng một tài liệu, và vẫn giữ hình học đơn giản. Ví dụ, bạn có thể chỉnh sửa một vật liệu đá có đá màu khác nhau, đó sẽ là khó khăn để đạt được bằng cách thêm hình học thêm, bạn sẽ cần các vật liệu khác nhau cho từng khuôn mặt mới. . | Measuring and Marking Angles Problem You need to measure an angle or create an angled construction line to mark an angle. Solution Use the Protractor tool. Discussion The Protractor tool can be used to measure angles and to create angled construction lines such as for roofs. To measure an angle 1. Position the protractor in the plane or face you want. If you want to orient the protractor to a standard plane or to another face set the orientation you want and hold the Shift key to lock the orientation. After you click to place the center of the protractor you can release the Shift key. 2. Click the corner whose angle you want to measure point 1 in Figure 10-25 . Then click anywhere on one edge that defines the angle point 2 and hover over a point along the other angle edge point 3 . The angle is listed in the Angle field. To create an angled construction line 1. Position the protractor in the correct orientation and click two points to set the baseline for the angle Figure 10-26 . 2. Move the mouse in the general direction you want for the line type the angle you want and press Enter Figure 10-27 . You can set the angle either before or after you click to create the construction line. Entering a negative angle places the construction line in the opposite direction from where you moved the cursor. Note-------------------------------------------------- If you don t want to enter angle values manually you can define snap values for the protractor. Open the Model Info window to the Units page and set the snap value under Angle Units. You can also enter an angle in rise run format such as 1 4 for example when defining a roof pitch.

Solution Use the Entity Info window or the Area option. Discussion Area calculation can be important if you need take-off quantities for painting or surface .
