[求助]：使用mdl怎么画share CELL呀??

确实有此问题！我也不知道如何解决，先在Bentley英文讨论组发一求助看看。

我把他mdlSharedCell_addToFile先写到文件在读出来更改比例在写回去就可以了
真是够费劲

Element Type 34 => Shared Cell Definition Element
Element Type 35 => Shared Cell Element
比例,旋轉都應該於 Type 35 設定

u2u: 用mdlSharedCell_create创建的就是Type35呀！

u2u · 发表于 2005-1-21 15:31:04

使用mdlSharedCell_create都正常呀!
比例也能設定!
其中SCOverride不能設定 NULL !!!

SCOverride不設定 NULL !!! 那么设置成什么值

mselems.h 中
typedef struct scOverride
{
#if !defined (BITFIELDS_REVERSED)
UInt16       level:1;          /* level override (true for pnt cells)  */
UInt16       relative:1;       /* relative or absolute          */
#if defined (BENTLEY_CPP_NAMES)
UInt16       classValue:1;    /* class value          */
#else
UInt16       class:1;          /* class value          */
#endif
UInt16       color:1;          /* color of all components          */
UInt16       weight:1;          /* weight of all components          */
UInt16       style:1;          /* style of all components          */
UInt16       assocPnt:1;       /* origin of cell is associative point  */
UInt16       unused:9;
#else
UInt16       unused:9;
UInt16       assocPnt:1;       /* origin of cell is associative point  */
UInt16       style:1;          /* style of all components          */
UInt16       weight:1;          /* weight of all components          */
UInt16       color:1;          /* color of all components          */
#if defined (BENTLEY_CPP_NAMES)
UInt16       classValue:1;    /* class value          */
#else
UInt16       class:1;          /* class value          */
#endif
UInt16       relative:1;       /* relative or absolute          */
UInt16       level:1;          /* level override (true for pnt cells)  */
#endif
} SCOverride;

或者 mdlSharedCell_extract (NULL, NULL, NULL, NULL, &SCOv, cellName, 64,
                        ShareCell_el, MASTERFILE);

mdlSharedCell_extract (NULL, NULL, NULL, NULL, &SCOv, cellName, 64,
ShareCell_el, MASTERFILE);
得到&SCOv之后在mdlSharedCell_create 比例还是不能使用

u2u · 发表于 2005-1-21 22:07:50

scale.x = scale.y = scale.z = 2.;
mdlElement_read (&ShareCell_el, MASTERFILE, GetPos);
mdlSharedCell_create (&new_el, &ShareCell_el, NULL, NULL, &scale, cellName, &SCOv, 0, 1, NULL);
mdlElement_add (&new_el);
mdlElement_display (&new_el, NORMALDRAW);

可以了谢谢楼上的原来用mdlSharedCell_addToFile比例不变
用mdlElement_add 才可以
