GRIP Introduction | Dimension Creation Statement List

创建尺寸标注概述

The GRIP statements used to create the objects are defined in Unigraphics using the Dimension Creation option. The statements are grouped to mimic Unigraphics to help you find the specific statement you want as quickly as possible.

Dimension statements fall into the following categories:

Since all of the dimensioning statements require you to specify an origin parameter and since the origin parameter has several options, this parameter is covered now, collectively, rather than with each individual statement.

The origin value specified in all dimensioning statements is used to position the dimension text. Enter the coordinates of the text origin, specify a previously defined point, or utilize one of the offset minor words (DELTA or DELCH) to locate the text in relation to another object (point or drafting object).

Text Origin for Dimensions and Drafting Aids

NOTE: In addition to the location of the origin with respect to the work coordinate system, the location of the origin with respect to the text may also be controlled by the global parameter access symbols (GPAs) for drafting objects.

In each dimension statement the word (origin) occurs, except in the ODIM statement where the origin has already been defined.

There are four options for defining the origin. Some of the statements have several fields, separated by commas. Be careful to use all of the commas in the required manner. You must replace the word (origin) with the complete statement. For example, the four options would be added to the concentric circles statement in the following manner:

Parameter Descriptions:

Parameter

Detail Description

x,y

The x and y values of the work coordinate system.

point

A previously defined point of which only the X and Y coordinates are used.

DELTA, {point|draft} dx,dy

The DELTA format positions the text at an offset distance from a previously defined point or from the origin of an existing drafting object. The offset distances are in unit values with respect to the work coordinate system. point - A previously defined point from which the offset is measured.
draft - An existing drafting object from whose origin the offset is measured.
dx,dy - The required offset distances in the respective X and Y directions of the work coordinate system.

DELCH {point|draft} dx,dy

The DELCH format positions the text at an offset distance from a previously defined point or from the origin of an existing drafting object. The offset distances are in multiples of the current character size with respect to the work coordinate system.
point - A previously defined point from which the offset is measured.
draft - An existing drafting object from whose origin the offset is measured.
dx,dy - The required number of character sizes to be offset in the respective X and Y directions of the work coordinate system.

For example, if the current character size is .125 and dx and dy are 10 and -10 respectively, the offset distances would be 1.25 in the X direction and -1.25 in the Y direction.
