Step 3 (continued):
· After you have clicked once, you will see the diameter of the first radius being altered by the movements of the mouse. As you move the mouse, the current radius is displayed in the info-bar (lower left corner of the screen). Now draw a circle with a radius of exactly 0.33 grid-units and make another mouse-click. After this, the cross-hair- cursor is re-centered and you can determine the second radius. Now draw the smaller end of the cone with a radius of exactly 0.18 grid-units and click again. Aligning the TC: In this step we will make the TC stand upright. For this purpose, you should change to the »left«-viewport by pressing » 2 « on the alphanumeric keyboard. Now choose the command »modify« | »rotate« and click on a line of the TC. You will get a bounding box and a cross-hair-marker in the middle of the shape. Rotate the TC 180° counterclockwise and perform a mouse- click. Alternatively you can also swap the cone with the command »modify« | »mirror«. After this, you can go back to the front-view. · Choose »modify« | »manual« and click on the TC. In the dialog-box, enter the following values in the these fields: Scale X: 0.330 Y: 0.330 Z: 0.100 Rotate X: -90 Y: 0 Z: 0 Translate X: -1,200 Y: -0.570 Z: 0.000· Clicking on the »ok«-button will align the TC in a way, that its top reaches slightly into the top-box of the banister. NOTE: Some of the procedures in the making of the TC were not really neccessary. · Nevertheless, these tutorial-steps have been set up that way intentionally, so that you get familiar with the mouse-functions for object-transormations. |
Step 4 (the upper torus):
· Now we have to create a torus, which will clip the top-TC on its bottom-end. since you know by now, how to create a torus (page 9 in this section), we can concentrate on the modifying-procedure. · You can certainly rotate, translate and scale (3D) the created torus with the mouse. For the »willess slaves of utmost precision«, here are the exact coordinates to enter in the manual-setup-dialogbox (these parameters fit, when the torus was created in the top-viewport). Scale X: 0.350 Y: 0.550 Z: 0.350 Rotate X: 0 Y: 0 Z: 0 Translate X: -1,200 Y: -0.700 Z: 0.000 Step 5 (the TC under the upper torus): · This step is a simple »copy«- and »rotation«-/»mirror«- routine. Of course the top-TC is the source-shape. Copy this one, start the manual-setup and enter the following values in these fields (top-TC was created in top-view): Scale X: 0.330 Y: 0.330 Z: 0.100 Rotate X: 90 Y: 0 Z: 0 Translate X: -1,200 Y: -0.835 Z: 0.000 Step 6 (the TC at the bottom): · For this purpose we will copy the TC under the upper torus. You can either scale and translate the shape with the mouse or you set up the cone manually. For the manual setup, here are the appropriate values ... Scale X: 0.275 Y: 0.275 Z: 0.085 Rotate X: 90 Y: 0 Z: 0 Translate X: -1,200 Y: -2.620 Z: 0.000(continued on next page) |
