第一确定你编译的版本和你说的书上的是不是同一个版本

如果是
那就是书有问题，或者是你看书设置的环境有问题，那里报错，看code debug下

如果版本不一致，那很有可能，这种问题你自己通过报错哪一行解决了

UF_DRF_create_vertical_dim( &object1, &object2, &dim_text, dimension_3d_origin, &dimension_tag );

书上用的是NX7.5我用的是NX8.5，就知道这行出错了。这一行错误但是我找不错误原因。

当前图纸共有：4个视图 *** ERROR code 68 at line 207 in drawing_view.cpp:

UF_DRF_create_vertical_dim( &object1, &object2, &dim_text, dimension_3d_origin, &dimension_tag );
空指针，还是没找到！

那就分析这个地方啦

我没法给你解答没时间给你调试这个

你多看看我录的 NX9 的二次开发视频教程吧书上的都是比较老的东西了
