Global Parameter Access Symbols Overview | Symbol List
This topic covers the Global Parameter Access Symbols (GPAs) for Drawing Control.
There are several terms associated with each GPA that define the way in which the symbol can be used.
|
ACCESS TYPE defines the READ/WRITE status of the GPA. GPAs contain data which is either object or number valued and which can be extracted (READ) for use in your program. Some symbols allow you to alter the data directly (WRITE) by assigning the properly valued data to the GPA.
DATA TYPE defines whether a particular GPA is object, number, or string valued. The data associated with a GPA, if object valued, must be treated like an object as it is assigned or extracted. If you READ an object valued GPA and assign the data to a variable, it must be declared as an ENTITY. Number valued GPAs, when assigned to a variable, do not need to be declared. String valued GPAs, when assigned to a variable, must be declared as a STRING. Refer to Data Types for further information, also see Declarations.
RANGE defines the numerical value which can be used with the GPA symbols in your program. Some GPAs have multiple parameters (e.g. &ON or &OFF) which have numerical values which lie within their RANGE.
When a drawing member view name is specified, it needs to be appended with an "@" character to denote it as a drawing member view. Specification of the view name this way is actually a short cut since the actual view name contains an integer following the "@" character. Optionally, you can enter the full name in order to assure uniqueness of member view names (drawings can have more than one instance of a given view on a single drawing).
An example of a drawing member view name that was in some way derived from the model view, TOP, is "TOP@3". To specify the name of the model view, "TOP" should be used. To specify the name of the drawing member view, either "TOP@" or "TOP@3" can be used. The full names of all the member views for a given drawing can be retrieved using DRAWV.
Functions that create, retrieve, or require the presence of a drawing will only be allowed in the Drafting Application when running interactive GRIP.
In GRIP, you cannot create drafting objects on the model within a drawing. You must create the drafting objects (e.g., dimensions) in the modeling display (see dimentioning in Dimension Creation Statements).
