Describing the Spigot
The following figure shows the general dimensions of the spigot:
Spigot—General Dimensions
The dimension S, the width of the spigot shoulder, can be computed from 1/2(D2-D1).
You can see that the geometry of the spigot is very simple. However, the macro we discuss in this chapter can be adapted to any complex geometric figure.
To test your macro, you may want to draw a block similar to the following sectional view, which shows holes of several different diameters at several different attitudes:
Sectional View of Test Block
The following figure shows the position of the spigot after you use the macro to insert the correct spigot in each hole:
