Build - Creating GD&T Annotations within SA
SA provides the ability to add GD&T annotations to a CAD model and provides the tools necessary to conduct a GD&T analysis on constructed SA geometry. To build your own annotations in SA use the GD&T tab in the SA toolkit, and for a basic case just follow these steps:
Defining Datums:
-
Choose between CAD Faces or SA Objects
-
Click the Datum letter button to start selection
-
Click in the graphics on the desired CAD face or SA Object to both define the attachment point for your datum and designate the feature as a datum.
Defining Checks
-
Choose the attachment target. Options include CAD Faces, SA Objects, SA Objects Fit to Points, and GR-Features.
-
Enter the Tolerance and Datums to include in the check (using the order of priority)
-
Click on the check button to define the check type
-
Click in the graphics on the desired face or object to define the features to inspect.
Notes on Selection
Here are a set of helpful hints and things to keep in mind when building annotations using the GD&T Toolkit tab:
-
The GD&T Toolkit tab is intended to be a quick means to build annotations in the graphics. For greater control or to edit existing annotations simply open the annotation properties from the SATree.
-
After an annotation has been created it will contain all the features associated and tolerance information. When the properties dialog is open the associated features will be highlighted and the annotation can be positioned as necessary.
-
The Feature Type selected greatly impacts the construction of GD&T annotations.
