[原创]封装简化Jig操作，函数式实现DrawJig
本帖最后由 作者 于 2009-12-31 0:03:40 编辑测试代码:
public void cc()
{
Circle cir = new Circle(new Point3d(), Vector3d.ZAxis, 10.0);
var v = Drag.StartDrag("\n开始Jig托动:",
rst => { cir.Center = rst.Point; rst.Draw(cir); }
);
if (v.Status != PromptStatus.OK)
return;
v = Drag.StartDrag(
new JigPromptDistanceOptions
("\n指定半径:"),
rst =>
{
cir.Radius = rst.Dist == 0.0 ? 1e-6 : rst.Dist;
rst.Draw(cir);
}
);
if (v.Status == PromptStatus.OK)
CAD.AppendEntity(cir);
}
封装成函数的jig~调用是不是很方便呢？？？
CAD.AppendEntity()函数请自写！（加入Entity到当前图面）删除这行也能单独测试Jig
下面函数式Jig模块代码：

<p>谢谢</p> 还是c语言强大，顶 飞诗也学C#了呀,我也从LSP跑到C#了呵呵 错误 1 无效的表达式项“>” 共同学习中，一起进步中，我向你们学习，学习你们的谨慎 收藏了，等C#有基础了再看！
