STEP 7 (the TC in the middle):
· Though this TC is not too different from the ones we have created so far, we cannot copy it, because none of the TCs availiable has the diameters, that we need. We have to consider, that the upper side of the TC in the middle has to fit perfectly onto the lower side of the TC under the upper torus! On the other hand, we have got the small TC at the bottom of the banister and so, the lower end of the TC in the middle has to fit onto the upper edge of the TC at the bottom (though this is not so important, because the second torus will cover slight inaccuracies, as we will see in the next step). · Due to the fact, that the TC at the bottom is just a scaled copy, we don't know its exact diameters - all we have got is the shape itself! In order to accomplish an accurate TC in the middle we will take the following precautions: Hiding elements: To get the right diameters for the TC in the middle we will visually orient on the diameters of the shapes, the middle-TC has to fit onto. To make this easier, we will hide the torus and all cones, that we don't need for now. To do so, follow these points: · A - deselect all objects (ALT+U); B: - in the front view, select the torus and all cones of the banister with the command »selection« | »area« (choose this command and draw a rectangle around these objects); C - after this, click on »selection« | »object« and deselect the cones at the bottom and the one under the torus. D - from the menu »display« choose the command »selection« (this will make the marked objects invisible); E - switch to the »modify«-menu, select the command »color«, click on the upper cone that is left and choose GREEN (a bright tone is recommendable); F - just as described above, change the color of the bottom-cone to RED (not too dark); G - switch to the top-view and zoom into the scene until the cones left fill out almost the whole viewport. · As you can see, the changing of the shapes color makes it pretty easy, to check the correct diameters. But now it's about time to draw the middle-cone. |
· Select »Truncated cone from the »Objects«-menu and select the top-view as the viewport to draw in. Position the cross-hair-cursor exactly into the center of the colored circles and draw the cone, aligning the outer diameter to the bigger green circle and fitting the inner diameter to the smaller red circle (make the last one a bit larger than the red circle). For the finishing procedure, you can go back to the front-view and scale the height of the middle-cone with the appropriate mouse-functions (»scale 2D«) or via the manual-setup-dialog. For the manual setup, here are the accurate vectors ...
Scale X: 0.330 Y: 0.330 Z: 0.810 Rotate X: 90 Y: 0 Z: 0 Translate X: -1,200 Y: -2.525 Z: 0.000STEP 8 (the final torus): · This shape can be copied from the upper torus and scaled and translated with the mouse. Sure, that we have some vectors for the manual setup as well ... Scale X: 0.250 Y: 0.040 Z: 0.250 Rotate X: 0 Y: 0 Z: 0 Translate X: -1,200 Y: -2.525 Z: 0.000STEP 9 (finishing the banister): · We will now copy the created toruses and cones, to get a symmetric look! Deselect all objects (ALT+U) and select the toruses and cones, using the command »selection« | »area«. Check out, that the »selection«-switch in the lower left corner of the screen is activated, copy the selection and translate it to the X-coordinate [1.20]. · Finally select all objects of the banister (including the top- and the bottom box) copy them and translate them onto the accurate position inbetween the remaining columns. This is it, one row of columns for our temple is accomplished - a good time to save the scene!
