多段线编辑命令快捷键

多段线编辑命令快捷键 工作学习中，经常会有对线条的处理，这个也已经成为AutoCAD操作的一种常态。其中，有一些操作非常必要，但是不熟悉的朋友又会感觉非常生涩。譬如说，如何将多段线与样条曲线进行互相转换呢, 这，牵涉到了两个部分: 一，是如何将多段线转换为样条曲线 二，是如何将样条曲线转换为多段线 将多段线转换为样条曲线的方法如下: 要将多段线转换为样条曲线，首先就先要生成多段线。 生产多段线的方法不少，最普遍的就是pline命令和pedit命令。 pline命令是用于创建多段线的，此处不作介绍。 这里，重点介绍的是pedit命令。 pedit——多段线编辑，别名pe。可将直线、圆弧、多段线进行合并。 生成了多段线后，就要将对象转换成样条曲线了。 首先，运行pe，选择[M]选项，再选择要进行转换的那些多段线。 spot welding, spot welding fittings mat must be placed firmly before, to avoid forced groups to arise, additional stress caused by crack. (5) the Groove position welds and welding the same welding process should be adopted, by qualified Welders and welding. Tack weld should be evenly distributed, there is generally no less than 2-3, length should be to 10-15mm, uniform distribution, wall thickness of no more than 2/3. (6) the tack should ensure good penetration and fusion, and free of porosity, slag and other defects. (7) to ensure the bottom bead molding well to reduce stress concentration, tack should be a smooth transition to the base metal and welds polished at both ends should be generated. (8) unless the process or inspection required-welded, but each seam continuous welding finish, otherwise again before welding, to preheat the weld. (9) the welding arc scraped surface is strictly prohibited, without any introduction arc welding on the surface. (10) should ensure that the arc and arc welding of quality, arc should fill crater, multi-pass welding joint should be staggered. (11) Tig welding should be ventilated in advance, expired after welding should be delayed, and should ensure that the welding in the welding process melts to get effective protection of argon gas. (12) when using the multi-pass welding, weld before should be cleaned, after making sure that no defects, and again the next. (13) the weld should be a smooth transition to the base metal and weld both ends ground into slope. (14) card with the welding, the material should be identical to the base metal, and at the time of demolition cards should not damage materials and residues in the welding scar on the base metal polished fixed flush to the base metal. (15) the finished weld, weld 之后，选择“样条曲线[S]”选项。 此时，你会发现，那些对象发生了很大的变化。 至此，肯定有朋友已经开始庆贺了:“我终于成功了～” 其实，如果你看看这些对象的特性，你就会发现，它的特性仍然是“多段线”。 郁闷了不是, 其实，你还差最后一步没有完成了而已。 最后一步就是—— 运行spline(样条曲线)命令，选择“对象[O]”选项，再选择那些已经处理过的多段线就OK了。 但是，通过这种方法转换出的样条曲线和一般使用spline命令创建出的样条曲线，在形状上还是有一些区别的。 区别如下 : spot welding, spot welding fittings mat must be placed firmly before, to avoid forced groups to arise, additional stress caused by crack.

(15) the finished weld, weld [快车下载]: 以上的两条样条曲线，洋红色的是通过pe命令转换成的，白色的是通过spline命令绘制成的，使用的是同样的控制点，结果却是不同的。 所以，请大家注意这两者的区别。 说完了将多段线转换成样条曲线的方法，也该说明一下逆过程了。 首先，要说明的是，在AutoCAD中，没有某个命令是可以直接将样条曲线转换成多段线的。 要得到这个结果的话，其原理，其实是用多段线来拟合样条曲线。 spot welding, spot welding fittings mat must be placed firmly before, to avoid forced groups to arise, additional stress caused by crack.

(15) the finished weld, weld 说白了，就是“描图”。 当然了，如果使用手工去一条一条地去描的话，就浪费了AutoCAD本身的功能了。 在此，介绍一个Express的方法。 将样条曲线转换为多段线的方法如下: 首先，先要确保你的AutoCAD已经安装了Express工具包。 之后，选中要进行转换的样条曲线。 然后运行flatten命令。 进入命令后，再回车一下就好了。 之后，选中这个对象，你就会发现上面多了好多蓝色的夹点，而对象的特性也已经变成了“多段线”。 命令介绍: flatten——将三维几何图形(当然，也可以是二维图形)转化为二维对象，形式为多段线。 这个就是将样条曲线转换为多段线的原理。 spot welding, spot welding fittings mat must be placed firmly before, to avoid forced groups to arise, additional stress caused by crack.
