最近在学习ARX自定义实体，定义好后，在CAD上使用，发现输入命令执行后，CAD上没有自定义实体图，全选后有几个夹点，刷新CAD马上就崩溃；后来试了下，发现worlddraw不执行；到底是什么原因了呢？我用的CAD2013,VS2010,ARX2013;下面是代码，麻烦帮忙检查下到底问题出在哪里呢？

CAD2013,应该搭配没有问题

请留下QQ,我远程给你看看

加载时要执行：
MyCustomEntityt::rxInit();
acrxBuildClassHierarchy();

edata · 发表于 2019-8-31 22:08:15

ACRX_DXF_DEFINE_MEMBERS(MyCustomEntity,AcDbObject,AcDb::kDHL_CURRENT,AcDb::kMReleaseCurrent,AcDbProxyEntity::kAllAllowedBits,自定义实体, "autoCAD")
AcDbObject 换成AcDbEntity

dwgInFields和out都应该是AcDbEntity

Acad::ErrorStatus MyCustomEntity::dwgInFields(AcDbDwgFiler* pFiler){
acutPrintf(_T("\nd**wginfields加载了"));
assertWriteEnabled();
AcDbObject::dwgInFields(pFiler);

关于MyCustomEntityt::rxInit();
acrxBuildClassHierarchy();
可以在自定义实体的头文件的尾部加入,就会自动注册
ACDB_REGISTER_OBJECT_ENTRY_AUTO(MyCustomEntity)

另外夹点移动的时候的代码不知道是谁写的,理论上应该是这样的.
// For A and center point
if (idx==0 || idx==4) m_PtA += offset;
// For AB and center point
if (idx==1 || idx==4) m_PtAB += offset;
// For B and center point
if (idx==2 || idx==4) m_PtB += offset;
// For BA and center point
if (idx==3 || idx==4) m_PtBA += offset;

大神啊！谢谢！谢谢！谢谢！按你说的改了，试了下终于出现图形了。

；再问下如果把实体类改为DBX,代码有什么不同吗？

edata · 发表于 2019-9-8 18:07:21

如果你指的用dbx项目写自定义实体,代码上没什么区别,dbx主要就是为自定义实体类设计的项目类型,方便管理.
本质上arx是一个特殊的dll,dbx更像一个dll,
