沙发一下

你的代码在吗？你的思路在哪？

ZZXXQQ · 发表于 2014-4-21 07:53:43

SOLID图元具有与多义线相同的顶点参数。可以根据其顶点坐标生成多义线，然后生成面域，生成并集，炸开再生成封闭多义线，然后再生成SOLID。

先看看solid实体的定义

xyp1964 · 发表于 2014-4-21 08:38:09

估计是想solid→hatch

品茗新秀 · 发表于 2014-4-21 11:24:23

这个看样子难度较大，顶出高手

Gu_xl · 发表于 2014-4-21 12:36:05

违背自然规律的提问！Solid对象只有四个顶点！

这个有点类似于把相交或者相切的圆连接成一个圆，连接是能连接上，关键它不再是圆了
