Variables and Related Parametric Tools

T-FLEX CAD variables are auxiliary elements of the system that allow you to define various types of non-geometric relationships between drawing elements.

For example, variables can be specified as parameters for construction lines. In this case, the value of the construction line parameter will be determined by the value of the variable. If the value of the variable changes, then the value of the construction line parameter associated with it (for example, the radius of a circle or the position of a straight line) will automatically change. Using variables, you can set the color and visibility of drawing elements, hatch parameters, text content, various parameters, etc. Variables can also be used when creating a 3D model.

By setting the relationship between the values of the variables that determine the parameters of the construction elements and the drawing image, you can achieve automatic change of the entire drawing when the value of one or more base variables changes.

Variables can be created in the T-FLEX CAD system in different ways:

•using the variable editor;

•when setting and editing the parameters of construction lines, as well as other elements of the drawing or 3D model;

•in the text editor;

•when specifying text strings in the parameters of some elements;

•when setting the values of almost all real parameters of elements (levels, priorities, etc.).

The main tool for working with variables is the variable editor. With its help, you can perform all actions on them.
