the transform menu

Introduction
This section describes the options of the transform menu. In general, these options are used to change the geometry of solids. The relevant geometric properties can be classified as relating to position, orientation, size and shape. Some of the available options are exclusively dedicated to animation functions. These are fix event, animation, view relative, simulation, move ani ax, ani ax to local and rotate track.
All transformations take place in a certain coordinate system. This is why all the above mentioned transformations can influence the position of the object. When modeling, the user has direct control over these coordinate systems. There is a global system and a local system for each subsolid. These systems, indicated with their axes, can be manipulated with the same transformation options as the solids themselves.
When animating, indicated with the animation button, these coordinate systems are no longer available. All transformations are relative to the transformation as established during modeling.
Furthermore each transformation is relative to the order with which they are evaluated in the animation module. To help the user, the displayed coordinate axes are adjusted during operation. Furthermore the modeling orientation and position can be adjusted for the animation, without effecting the modeling itself, with move ani ax and ani ax to local.
When modeling, all transformations can be used to multiply a solid. The options xy and grids with snap constrain the transformation degrees of freedom.
