antisars 的作品:
<img src="attachments/dvbbs/2004-1/200411918352192483.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/2004-1/200411918352192483.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
以下方案可行吗?
1、你在绘制圆柱螺旋线时设置t的终止 为90度,我改为72度。这是因为动点M升高40毫米时t=360度,动点M升高8毫(芯高8毫米),t=72度。
2、相应第一条截面线另一端点坐标为(15、0、0),第二条截面线另一端点坐标为(0、15、8)。
初步结果如下:
