版主,各位高手,请进来做做这个特殊曲面.

如图,我想用造型做一个像喇叭一样凹下去的形状曲面.上面要椭圆状的,但在PROE中椭圆或圆是由两边组成的,所以裁剪下去,那椭圆状也由两边组成,我用组合曲线将它组合,但用造型也不能创建曲面.用造型中的分割合并曲线,又不能将两边界合并,怎么办?
如果用边界曲面,由于曲线和上面曲面边界设置相切,导至不能创建.取消相切就行.
当然,如果将椭圆改用曲线去裁剪,就一切解决了,可是,用曲线根本描绘不出一个真正的椭圆来.<img src="attachments/dvbbs/200310111572882392.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/200310111572882392.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
