I. Overview:
Direction wirings quadrilateral with predictable flow: quads best wiring, wiring in quads, or effect selection direction (e.g., cutter circulation mode) is predictable.
Second, the number of wiring Example:
1, around the corner:
Generating a multi-wiring but such are rounded
Therefore, to facilitate this figure and a sharp transition line (smoothed segment)
But this will not cycle through the edge, in the figure above solution is then added to eliminate some lines lap
2, Interchange:
Multi-line brings together the best of circumstances to eliminate
It can be eliminated by the way that it forms four sides face in FIG.
3, at the edge:
Method 2
4, the projections:
At common wiring projections
5, a recess:
1 at the wiring recess: a new line (Note: triangular face may be formed first, and then add a little at the edge, plus line forming quads) by the sliding tool or cutter tool
Wiring recess 3
Note: The above method is suitable (plus line operation) when creating convex or concave sharp edges and corners
6: Processing twisted wire
Then add the line to eliminate, with respect to the wiring so that the turning point is symmetrical
7: Sharpen the edges under special circumstances
Normally we choose to add to the tangential line to sharpen edges and corners, but such lines after subsequent processing will be very complicated Cadogan
We can simplify the process in such a way
Third, some tools:
1 "rotation side" command: Note that the effect of smoothing the edges, this operation may be performed at one edge to form a wiring problem quads, this technique is more suitable for a wiring on the surface. (Here are a few application mode)
a：
b：
I do not want to cut the tangent cylinder how to do? (Such a cylinder will have some problems smoothed)
While rotating command can be used to make changes in the tangential direction (Note: Not triangles produced after rotation)
Similarly, the tangential direction of free rotation change
c：
How to increase this figure the outer edge of the line?
You can use spinning side
While rotating together with the line, but there are two internal polygon (recessed quadrilateral) treatable
Side rotating operation again
2. Path Selection (It is noted that the operation on the basis of, e.g. chamfered)
3. Slide the tool (much more than a simple sliding operation of the edge point)
Highlights:
a、勾选内部的克隆设置后，是沿着边进行平行复制，这样的效果不会产生方向变化
b、在勾选保持曲率后，它可以产生较好的细分过渡
内部挤压
滑动
想在边缘制造缺口用切刀、内部挤压都不是快速准确的方式，可以选中内部三条边后用滑动工具形成内部挤压后操作
局部细分
勾选保持曲率
四、法线：
分类：分为多边形法线和顶点法线（shift v后勾选显示）
与坐标轴相分离：多边形法线总是均匀的分布于顶点法线的中心点，所以当你移动一多边形的顶点后它的中心轴不会变，但多边形法线会发生偏移，所以有了沿法线旋转等法线操作。
平滑着色数值越大，相应区域显示的就越平滑，反之，不平滑。
