有两种方式可以创建草图:- Y6 k7 d' w& H9 }2 a
1)通过参考平面创建
7 G$ A- s$ c9 s2 G+ y首先获取一个CATIPrtPart变量:
5 W8 W& L) m2 P* }' T, P- X; K/ {CATIPrtPart_var spPart(pIPrtContOnDocument->GetPart());/ G! k5 E9 F9 \! K/ P" { o9 g
pIPrtContOnDocument->Release();
" t( G* D/ L# T% y/ Y" f有了CATIPrtPart变量就可以利用其方法GetReferencePlanes(),获取参考平面( [( w4 E; a5 A5 r- @
CATLISTV(CATISpecObject_var) spRefPlanes = spPart->GetReferencePlanes();
: l6 J( p7 e# O: S7 I% J% u7 N/ U然后创建XY plane (spRefPlanes[1])
0 k& l6 y3 ]! \' ^, ICATISketchFactory_var spSketchFactory(pSpecContainer);- X4 B, V% L( {* B6 J g
if ( NULL_var == spSketchFactory ) return (CATStatusChangeRCCompleted);
0 J# ^0 ?* O; E6 a! f( F9 BCATISketch_var spSketch(spSketchFactory->CreateSketch(spRefPlanes[1]));
: @8 E/ j/ F0 i8 A' dif ( NULL_var == spSketch ) return (CATStatusChangeRCCompleted);
) j! o9 l8 m+ w- nspSketch->OpenEdition();( y# G6 @& n C& h0 {
2) 通过原点和两个矢量方向, s" z* w" d- L% I# D6 D6 f6 N. G
该方法是通过定义一个原点和两个方向pH、pV 进行创建。
2 U8 \( n4 f4 H" J8 C9 R& G" v4 }3 U定义原点和方向:
% M% ?! y) w+ i Y9 u6 ~ h3 M1 d! G, Udouble origin[3]={0.0,0.0,10.0};
8 E0 }# m! }# W5 v( @2 qdouble x_dir[3]={1.0,0.0,0.0};
_3 E! _4 E9 f9 l2 {double y_dir[3]={0.0,1.0,0.0};
7 O* c7 J& U7 i- q5 |. ^4 z$ KCATISketchFactory_var spSketchFactory(pSpecContainer);
* b# d- s7 l/ l, b) G2 q3 O! @# `if ( NULL_var == spSketchFactory ) return (CATStatusChangeRCCompleted);+ v# T1 d" K$ b
CATISketch_var spSketch(spSketchFactory->CreateSketch(origin,x_dir,y_dir));
) R, W4 T3 q0 ^8 @) B2 u5 J' \if ( NULL_var == spSketch ) return (CATStatusChangeRCCompleted);6 J# E8 `# J8 }: K2 s
spSketch->OpenEdition();
7 x* U: \; e, ?* c P2 N到这里,你已经创建了一个Sketch,你可以在上面创建任意的草图了。
1 o' h. |* u6 R, t; ~8 D# J# R创建好记住要将其关闭:
4 T4 L! j1 _* X* s& N/ h) zspSketch->CloseEdition();
; x7 E T( x6 j/ D: W; {" H) ^7 {% b% j$ u# O
, a3 A+ y9 N6 b- z |
