我在PRoE中建模，保存成x_t文件，导入Adams时，弹出如下错误提示：

ERROR:   The reference marker of an extrusion, revolution, or shell must
belong to the same part as the extrusion, revolution, or shell.
ERROR:   The reference marker of an extrusion, revolution, or shell must
belong to the same part as the extrusion, revolution, or shell.

我以为是我在PorE中建模存在错误，重新试了两次，结果两次都有不同的构件无法定义质量参数，求大神指教。
