GENERATE STRESS ISOMETRICS OVERVIEW Generate Stress Isometrics on the Home tab creates stress isometric drawings. Using Stress Isometric Annotations you can include the piping model data created by CAESAR II in the display area and then generate a stress isometric drawing. CAESAR II classifies the piping model data as input and output. The data you enter to define a piping model is the input data, and the data generated by CAESAR II after analyzing a model is the output data. The Stress Isometric Tutorials are design to familiarize you to the interface and explain the procedures in more detail with the help of examples and illustrations. We recommend you read the tutorials and follow the instructions if you have not previously created a stress isometric drawing. The tutorials instruct you in a step-by-step manner to open a piping model, add annotations, and create a stress isometric drawing.

TUTORIAL B - ADDING ANNOTATIONS FOR INPUT AND OUTPUT FEATURES This tutorial instructs you on how to annotate input and output features of a model. The Stress Isometric Annotations pane lists all the input and output features used in the CAESAR II file.
Adding annotations for input features In Tutorial A, we learned to open a CAESAR II file and create a drawing without any annotations. All the information associated to the input features is saved in the CAESAR II file when you define specific inputs for a model. You can make the drawing more insightful by adding this information to the drawing. In this part of the tutorial we add annotations for input features to the Relief.c2 file. 1. 2. 3.
Select File > Open. On the Open dialog box, click the Examples button on the right side. Select RELIEF.c2 from the file list, and then click Open.
4. 5.
On the Home tab, click Generate Stress Isometrics to open the model in the C2Isogen module. Select StressIso > Annotations to open the Stress Isometric Annotations pane. By default, the pane opens the Input tab.

The Feature list displays all the input features available in CAESAR II. Depending on the feature you select a list of nodes associated to the feature is displayed.
7.
Click the check boxes in the Select column if you want to include the information associated to the node or element in your drawing. For example, select Node Numbers in the Feature list, and then select nodes 110 and 115. Annotations for the selected node numbers are added to the model and are visible in the display area.
Adding annotations for output features Similar to the input features, CAESAR II file saves the result data after you analyze a model. The Output tab lists the load cases used for the stress analysis and classifies them as Displacement, Restraint, and Stresses induced in the model for each case. You can make this result data available in the drawing by selecting nodes and elements displayed for the result type. To add annotations for output features: 1.
Select the Output tab to view the load cases used for stress analysis.

2.
The Load Cases list displays a list of load cases used in the analysis, the results generated for each load case are listed in the Results box. You can view a list of nodes or elements for each result set and then select nodes and elements you want to annotate. Let us consider Load Case 3 and then select elements 75-80 and 110-115 for Stress. You can now view the annotations for the selected elements in the display area.
TUTORIAL C - ADDING
CUSTOM ANNOTATIONS AND CONFIGURE ANNOTATIONS
PREFERENCES
Along with annotating input and output features you can also add custom notes to the nodes and elements of a model. The annotations you add can be represented in different formats to improve drawing readability. In this tutorial we learn to add custom notes to nodes and elements and choose representation formats for the features.
Adding custom annotations In the earlier tutorial we learned to add annotations for input and output features. In this tutorial we continue adding annotations to Relief.c2 file we opened in Opening an existing CAESAR II file. To add custom annotations: Select Nodal Annotations tab to view the list of nodes defined in the model. You can now add your remarks in the User Annotations cell associated to each node. For example, click the cell associated to node 80 and type This is a user annotation for node 80.

Similarly, select Elemental Annotations tab to view the list of elements in the model and add your remarks in the User Annotation cell associated to the element you want to annotate. Here we add a note for element 75-80. Click the User Annotations cell associated to element 75-80 and type This is a custom annotation for element 75-80.
The custom annotations you add are not shown in the display area and can be viewed only in the drawing.
Configuring annotation preferences All the information that you annotate in your drawing can be represented in different formats, selecting different textbox shapes to display different feature can make the drawing more easy to understand. In this part of the tutorial we learn to configure annotation preferences for the drawing. It is evident in the drawing illustrated in the first part of this tutorial that all the annotations you made are displayed in a rectangular box. This makes it difficult to differentiate between the input, output, and custom annotations added to the drawing. To choose different formats to represent your annotations: 1. 2.
Select the Settings tab to view the list of input, output, and custom annotation features. You can select different box shapes for the features you annotate. Let us select Circle for Node Numbers, No Box for Output Stress Data, and Filleted Rectangle for Nodal Annotations and Elemental Annotations.

You cannot view these changes in the display area, the changes you made are updated when you create a drawing
TUTORIAL D - CREATING AND APPLYING A STRESS ISO TEMPLATE This tutorial instructs you to create a template for stress iso annotations .You can apply this template to your piping models and ensure consistency in representation of the input features in the drawing. Only input features of a model can be included in a template, we recommend you open a piping model that has all the input features you want to include in your template.
Creating a template In this tutorial we learn to create and save a stress iso annotation template. For this tutorial, open Relief.c2 from the CAESAR II example folders. To create a template: 1.
2.
Select StressIso > Annotation to open the Stress Isometric Annotations pane. You can only include the input features in a template. To include an input feature in a template you must select all the nodes listed for that feature. Click the Feature list, select a feature, and then select all the nodes listed for the feature. For example let us select all the nodes listed for the Restraint/hanger Types feature.

3. 4. 5.
Similarly, select all the nodes or elements of other input features that you want to include. Select Settings tab to specify a text box shape for the input feature you selected in the earlier part of this tutorial. Let us select Filleted Rectangle for the Restraint/hanger types feature. Select StressIso > Save Template to save your selections as a template. A template file with .ist extension is saved in the model folder.
Applying a template After you create and save a template, you can apply this template to your piping models. When you select all the nodes of a feature to create a template, that input feature gets selected when you apply the template to a new piping model. You can clear the selections if you do not want to display all the nodes or elements of the input feature included in a template. This part of the tutorial directs you on how to apply a saved template to a piping model. You can apply a template to a piping model only if the model is not already annotated and the stress iso file (.iso) associated to the model does not exist. To apply a template to a new model: 1. 2. 3.
Select Start > Intergraph CAS > CAESAR II > CAESAR II. Select File > Open. On the Open dialog box, click the Examples button on the right side.
This opens the Examples folder. 4.
