R3d902戒指的建立
The establishment of the R3d902 ring
戒指的定型和主石的建立
Design the pattern of the ring and establish the main stone
在正视图，使用圆形命令制作一个直径为17mm的圆形，再制作两个圆形，直径分别为3mm和1.2mm，大圆形放在上面，小圆形放在下面，分别代表戒指上下的厚度。使用左右对称线绘制戒指的外圈的曲线，并封口。
On the front view, use the circle order to create a circle in 17 mm diameter, and then make two other circles which diameters are 3 mm and 1.2 mm. Put the big circle above the small one, representing the upper and below thickness of the ring. Use the left and right symmetry line to draw the outer lane of the ring, and seal.

转到上视图，先用圆形命令制作两个圆形，直径分别为7.3mm和6.3mm，接着使用上下左右对称线绘制一个椭圆，接着将椭圆曲线增加控制点2倍，使用偏移曲线命令向内偏移距离为1mm的椭圆，再使用曲线的中间曲线命令增加中间曲线，并封口曲线。Turn to the top view, use the circle order to create two circles first, which diameters are 7.3 mm and 6.3 mm, use the top and bottom symmetry line to draw an oval, use the oval curve, increase control point 200%, and then use deviate-curve order to make oval 1mm away deviate, then use the middle curve order to increase one more middle curve, and seal the curve.

从石头命令中拿出一粒圆形石头，先用尺寸命令放大，再用尺寸命令，按右键变形，把石头变形为椭圆石头。选择里外两个椭圆曲线，转到正视图，先用圆形命令制作一个直径为4mm的圆形，把两条椭圆曲线移到4mm圆形下面；再转到上视图，选择中间曲线，又转到正视图，把中间曲线移到上面。转到上视图，使用左右对称线绘制切面曲线，打开导轨曲面命令面板，选择三导轨，单切面，宽度切面量度，建立椭圆曲面。
Create a round rock by the rock order, and enlarge it by the size order first, then use the size order again, and click the right button to transform it to an oval rock. Choose the two outside and inside oval curves, then turn to the front view, create a circle in 4 mm diameter by the circle order first, move the two oval curves under the 4 mm circle. Turn to the top view, choose the middle curve, and then turn to the front view again, move the middle curve to the top. Turn to the top view, use left and right symmetry line to draw tangent plane curve. Open drive surface order board, choose triple rail, the single tangent plane, and the tangent plane width measurement, to create the oval curved surface.

使用圆形命令制作一个直径为13.2mm的圆形，接着用辅助线命令拉两条辅助线来定义戒指的宽度。转到正视图，用圆形命令制作一个直径为5.6mm的圆形，把圆形移到上面，定义椭圆镶口的高度，接着选择椭圆镶口，移到刚制作的圆形的高度。
Use the circle order create one circle which diameter is 13.2 mm, and use the assistance line order to create two assistance lines to define the width of the ring. Turn to the front view, use the circle order create a circle in 5.6 mm diameter, and move it to the top, to define the height of oval mount. Choose oval mount, move it to the height of the lately- create circle.
