Analysis for Composite Solids (组合体的形体分析)



Analysis for Composite Solids 组合体的形体分析 

   Composite solids are composed of some basic solids, such as columns, cone, spheres etc.. 

组合体由若干柱、锥、球等基本几何体组成。

Configuration of composite solids组合体的组合形式 

   1. Union(Superposition)  叠加(堆积) 

   2. Subtraction(Cutting)  切割(截切)

   3. Integration (Hybrid)  综合(混合) 

Relative positions of composite solids 形体表面间的相对位置关系

1.Alignment  平齐

   When neighboring planes are aligned, there is no line between their projections in a view. 

当相邻平行表面平齐时,在两表面的投影之间不画线。 

2.Non-alignment 不平齐

   When neighboring planes are not aligned, there should be a line to separate their projections. 

当相邻平行表面不平齐时,在两表面投影之间画分界线。

3.Tangency  相切

   When two neighboring surfaces are in tangent ondition, there is no line between their

projections.

当相邻表面相切时,在相切处不画线。 

4.Intersection  相交 

   When neighboring planes intersect, one should draw the projection of the intersection line. 

当相邻表面相交时,在相交处应画出交线的投影。
