Example: Parameters in Notes
The following example illustrates the parameter’s usage in notes:
1. In Part mode, assign the name "A" to a surface.
2. Create a parameter with a name "RAD," of type Number.
3. Assign a value ".03" to this parameter.
4. In Drawing mode, create a note by typing [Break sharp edge with R = &RAD:SID_A]. This note appears: "Break sharp edge with R =.03".
If a drawing note has a single attachment (defined using On Item or one leader line), you can show the parameters of the entity to which it is attached by typing the following string into the note: &param_name:att. The system then interprets the param_name in a series of contexts until it is able to evaluate it successfully. First, it searches the immediate entity to which the note is attached, such as an edge. Next, it searches the feature that owns the entity. If it still cannot evaluate the parameter, it then searches the model that owns the feature. Finally, if applicable, it searches the component that refers to the model. If you want to specify the exact context in which to interpret the parameter, specify a full "att_" suffix instead.
After you create the note, if you choose Annotate > Parameters > Switch Dimensions menu, the system appends the "att_" suffix to specify the exact context in which it interprets the parameter.
Param_name:att_edge
Edge
Param_name:att_feat
Feature
Param_name:att_mdl
Model
Param_name:att_cmp
Component
For example, if a note is attached to an edge by a single leader line (or defined using On Item), you can set the note to show a relational parameter of that edge by typing [&Length:att]. The note then appears as follows: &Length:att_edge.

You must create the drawing note after you create the parameter; otherwise, the system does not evaluate it correctly.
