正四面体建模的启发(Inspiration of tetrahedral modeling)

法一:上面有多边形快捷,选3

3D草图绘制,但是注意:线条画完一次完成一次很关键!

点击曲面里的填充曲面,先填充底面,一个一个填充,最厚缝合曲面

再点击加厚,形成实体

法二:多边形绘制3再拉伸

在上顶面利用两直线中心确定重心

3D草图后建立基准面

利用曲面里的使用曲面切除

————————

Method 1: there are polygons on it. Select 3

3D sketch drawing, but note: it is crucial to finish the line drawing once!

Click the filling surface in the surface, fill the bottom surface first, one by one, and stitch the thickest surface

Then click thicken to form an entity

Method 2: polygon drawing 3 and then stretching

Determine the center of gravity on the upper top surface by using the centers of two straight lines

Establish datum plane after 3D sketch

Use surface cut in surface
