Complicated joint patterns can be created by Interactive database editing. For illustration purposes, let's assume that you need to assign a complicated joint pattern that described by a function of joint global Z coordinate. This type of joint pattern can be applied using the following steps:
(1) Define new joint pattern via "This tutorial demonstrates the assignment of complicated joint patterns using interactive database editing. The process outlined below will follow the development of a model where coordinates are a function of the global Z-axis.
Joint-pattern assignment using interactive database editing proceeds as follows:
Define a new joint pattern through Define > Joint Patterns > Add New Pattern > Name

Click OK to open the tables.
(3) Select "Joint Coordinates" table in the drop-down list and click "To Excel". This will open the joint coordinates table in Excel as shown in the figure below:
