建模问题

我正在做一个钢管混凝土的模型,但是按照< >中所介绍的方法定义截面的时候,出现了:
The requested EPLOT command cannot be executed.
Either elements do not exist or the selected elements
are not supported by PowerGraphics.
To correct this situation, try selecting different
elements,etc, or turning off PowerGraphics.
因为我想定义几个截面,所以还得清屏后继续定义截面,不知道如果是好?还请高手不吝赐教啊!

程序:
/prep7
/title,the analyse of steel arch bridge

执行到此,不能使用/replot,因为屏幕左上角还有一个ELEMENTS怎样去除啊?
