50. 关闭实体块表记录
53. pLine1->close();
54. pLine2->close();
55. pCircle->close();
56. pBlkTblRcd->close();
59. }
62. 插入块参照
63. static void TESTaddblkrefcmd(){
65. 获得用户输入的块定义名称
66. CString strBlkDef;
68. if(acedGetString(Adesk::kFalse,采用T("\n输入块名称\n"),strBlkDef.GetBuffer()) != RTNORM){
69. return;
70. }
71. acutPrintf(strBlkDef);
76. 获得当前数据库的块表
77. AcDbBlockTable* pBlkTbl;
80. acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlkTbl,AcDb::kForWrite);
84. 查找用户指定的块定义是否存在
88. if(!pBlkTbl->has(strBlkDef)){
89. acutPrintf(采用T("\n当前图形中未包含块定义"));
90. pBlkTbl->close();
91. return;
94. }
97. 获得用户输入的块参照的插入点
98. ads采用point pt;
99. if(acedGetPoint(NULL,采用T("\n输入块参照的插入点"),pt) != RTNORM){
101. pBlkTbl->close();
102. return;
103. }
106. AcGePoint3d ptInsert = asPnt3d(pt);
109. 获得用户制定的块表记录
110. AcDbObjectId blkDefId;
111. pBlkTbl->getAt(strBlkDef,blkDefId);
114. 创建块参照对象
115. AcDbBlockReference* pBlkRef = new AcDbBlockReference(ptInsert,blkDefId);
118. 将块参照添加到模型空间
121. AcDbBlockTableRecord* pBlkTblRcd;
122. pBlkTbl->getAt(ACDB采用MODEL采用SPACE,pBlkTblRcd,AcDb::kForWrite);
124. AcDbObjectId entId;
125. pBlkTblRcd->appendAcDbEntity(entId,pBlkRef);
128. 关闭数据库对象
129. pBlkTbl->close();
130. pBlkTblRcd->close();
131. pBlkTbl->close();
132. }
135. ===================================================插入带有属性的块定义
138. static void TESTaddblk2cmd(){
141. 获得当前图形的数据库块表
142. AcDbBlockTable* pBlkTbl;
143. acdbHostApplicationServices()->workingDatabase()->getBlockTable(pBlkTbl,AcDb::kForWrite);
144. 创建新的块表记录
147. AcDbBlockTableRecord* pBlkTblRcd;
150. pBlkTblRcd = new AcDbBlockTableRecord();
153. 根据用户的输入设置块表记录的名称
156. CString blkName;
157. if(acedGetString(Adesk::kFalse,采用T("\n输入块表记录名称:"),blkName.GetBuffer()) != RTNORM){
159. pBlkTbl->close();
160. delete pBlkTblRcd;
161. return;
162. }
163. pBlkTblRcd->setName(blkName);
166. 将块表记录添加到块表中
167. AcDbObjectId blkDefId;
168. pBlkTbl->add(blkDefId,pBlkTblRcd);
169. pBlkTbl->close();
174. 向块表记录添加实体
175. AcGePoint3d ptStart(-10,0,0);
176. AcGePoint3d ptEnd(10,0,0);
179. AcDbLine* pLine1 = new AcDbLine(ptStart,ptEnd);
180. ptStart.set(0,-10,0);
181. ptEnd.set(0,10,0);
182. AcDbLine* pLine2 = new AcDbLine(ptStart,ptEnd);
183. AcGeVector3d vecNormal(0,0,1);
184. AcDbCircle* pCircle = new AcDbCircle(AcGePoint3d::kOrigin,vecNormal,6);
185. 创建一个属性，输入直径
186. AcDbAttributeDefinition* pAttDef = new AcDbAttributeDefinition(ptEnd,采用T("20"),采用T("直径"),采用T("输入直径"));
187. AcDbObjectId entId;
188. pBlkTblRcd->appendAcDbEntity(entId,pLine1);
189. pBlkTblRcd->appendAcDbEntity(entId,pLine2);
190. pBlkTblRcd->appendAcDbEntity(entId,pCircle);
191. pBlkTblRcd->appendAcDbEntity(entId,pAttDef);
194. 关闭实体和块表记录
195. pLine1->close();
196. pLine2->close();
197. pCircle->close();
198. pAttDef->close();
199. pBlkTblRcd->close();
200. }
