[求助]：如何实现对面域求并集,交集,差集???

HillMan

就类似于autocad的union命令那样的???
谢谢!!!

region 本来就可以使用 Union 命令.

Combines selected regions or solids by addition

编程还可以用
Boolean mothod

Performs a Boolean operation (union, intersect, or subtract) between the object and another 3DSolid or Region object.


Signature

object.Boolean(Operation, Object)

Object

3DSolid, Region
The object or objects this method applies to.

Operation

AcBooleanType enum; input-only

acUnion: Performs a union operation.

acIntersection: Performs an intersection operation.

acSubtraction: Performs a subtraction operation.

Object

Object; input-only
The object the operation is performed against

HillMan

不过这么生成的时候好象效率很低的!!!
有没有更好的方法啊???
用ARX实现Rgoin的这些布而运算如何来做呢???

Lisp 也只有如此了

2. 
   
3. (defun c:Test (/ e1 e2)
   
4.   (if (and (setq e1 (vlax-ename->vla-object (car (entsel))))
   
5.            (setq e2 (vlax-ename->vla-object (car (entsel))))
   
6.       )
   
7.     (vla-boolean
   
8.       e1
   
9.       acIntersection
   
10.       e2
    
11.     )
    
12.   )
    
13. )
    

<br /> (defun c:Test (/ e1 e2)<br />   (if (and (setq e1 (vlax-ename->vla-object (car (entsel))))<br />            (setq e2 (vlax-ename->vla-object (car (entsel))))<br />       )<br />     (vla-boolean<br />       e1<br />       acIntersection<br />       e2<br />     )<br />   )<br /> )<br />
