Element Variables

In the same way as you enter value parameters for parts (e.g. for the length of a cuboid), you can also input formulas for elements (e.g. for the edge to which a flange is added).

Element variables can be used in parametric constructions. Within element variables, there are a number of functions which can be used in formulas and take the element variables as parameters.

Example: edge_length, distance_points, ... (For the complete list, see Feature Parameter Formulas)

Example: A parametric construction produces an edge whose length the user measures off in order to use the value, say, as the depth of a subtraction. If a change to a parameter changes the length of the edge, the subtraction feature currently still contains the old length as a fixed value. In this situation, the user can now define an element variable of type Edge (e.g. depth edge) and then parameterise the depth in the subtraction feature using theedge_length (depth edge) function.
