使用“Rebar Layer”定义混凝土桩纵筋，data check显示缺少Section定义？

使用软件版本为ABAQUS 6.10

在Part中使用“shell-Extrusion”建立了实体，然后在Property中新建“section”—“shell”—“Surface”，使用Rebar Layer进行Section设置，并最终对之前Part的实体记性赋值

此时运行“Job”中的“data check”显示单元未定义或者丢失：

Error in job Job-1: 5736 elements have missing property definitions. The elements have been identified in element set ErrElemMissingSection.

Error in job Job-1: SECTION DEFINITIONS ARE MISSING OR INCORRECT FOR THE ELEMENTS INDICATED ABOVE. FURTHER PROCESSING OF THE INPUT FILE IS NOT POSSIBLE UNTIL THIS INPUT ERROR IS FIXED.

Job Job-1: Analysis Input File Processor aborted due to errors.
