A joint is identified at the free end of a structural member or at the
intersection of two or more structural members.

Click to calculate the joints.
The software highlights with pink color the joints where two or more structural members intersect,
and with light green color the joints of a structural member
at its end and mid-points. Example
The program treats touching,
interfering and non-touching structural members within a tolerance automatically
as beams and calculates the joints. However extrusions that are solids
can be treated as beams if desired (Right-click the Solid
icon and select Treat as Beam).
For extrusions that are treated as beams, the program does not automatically
