Object Group [SIG]

OpenBrIM allows users to store one set of analysis results and one set of design results per model. However, users can also generate multiple FEA results and design reports for specific parts of a bridge, or by excluding certain elements. By activating or deactivating object groups, users can compare FEA results and code check reports for both the initial model and the modified condition with selected elements activated or deactivated.

This feature allows you to group objects within the project. You can activate or deactivate the objects in each group you create, and generate FEA results and Code Check reports for both the initial condition and the condition where certain objects are activated or deactivated.

Pick Objects: The objects to be grouped can be picked one by one. However, it is easier to select all group objects by picking the main object first, and then selecting the reference objects associated with the main objects using 'Select References'.

About Select References

After selecting an object, users can choose the "Select References" option (accessible through the three dots). This option allows users to pick related objects associated with the selected object.

For better illustration, consider the example below:

After selecting the Support Line Pier 2, the "Select References" option can be used to choose related objects linked to the selected Support Line.

One important thing to note when using the Select References window is that when an object is selected, all related objects will automatically be selected as well. As shown clearly in the video below, when insertion points are chosen, related elements, such as girder layouts, girders, and splices, are automatically selected. These related objects can be deselected by deselecting the primary connector object.

Select Objects: Objects that cannot be picked, such as code check reports which is not visible on the project screen, are selected using 'Select Object'.

Active: According to the 'Activation/Deactivation Impact', active objects' 3D geometries, finite models, and design reports can be enabled within the group, while those of inactive objects are not displayed in the project.

Activation/Deactivation Impact: The selection determines whether the object group affects the FEA model and/or Design reports.

FEA and Design Reset : Select this option when the activation and deactivation of selected objects affect both the finite element analysis (FEA) results and their design reports. For example, consider Unit 1 and Unit 2 of the same bridge. This option stores the FEA and design results of both models using a unique key, allowing you to check the results for Unit 1, then activate Unit 2 to view its results, without overwriting or deleting the results of the other unit.
Design Reset : Select this option when the activation and deactivation of selected objects affect only the design reports, without changing the FEA results. For instance, superstructure code-check objects and substructure code-check objects can be organized into two separate groups. When one group is active, the same FEA results can still be used. The advantage of using this option is that you will not lose the superstructure code-check report when you activate the substructure code-check objects.

To better understand the options for 'FEA and Design Reset' and 'Design Reset', follow the steps below.

1) FEA and Design Reset

1	Log in to your account and locate the 'Project' option in the top right corner.
2	Click on 'Project' and then select 'NEW' from the top left corner of the screen.
3	Under the 'Example Project' section, click on 'New Project' specifically located within the 'Precast I-Girder Training Example'.
4	Provide a name for your project and proceed to open the example project.
5	Please note that the initial download process for the library components take approximately 2 minutes and 30 seconds to complete. The reopening of the same project will experience a notable increase in speed, primarily due to the caching of OpenBrIM library objects within your browser. The loading of library objects during this process generally takes less than 2-3 seconds

7	Click on the 'Data' button below.
8	The window that opens below shows the workflow tree on the left and the spreadsheet of the selected object on the right.
9	Scroll down in the workflow and click on the "Object Group" within the "Organization" group.
10	Name the group you are determining.
11	Click on three points by clicking on 'Pick Objects' input, then select 'Pick'.
12	Pick the 'Abut1' and 'Pier1' support lines on the project screen for UnitSpan1.
13
14	Click on 'Select References' by clicking on three points.
15	In the opened 'Select Referencing Objects' screen, all reference objects related to the selected 2 support lines are listed.
16	When you click on any object, all reference objects of the clicked object are selected on the screen.
17	Click 'Abut1' and 'Pier1' to select all their references. Then, remove the selection of 7 insertion points belonging to the second span (IP11, IP12, IP13, IP14, IP15, IP16, IP17).
18
19	Click on the 'Select' button at the bottom right of the 'Select Referencing Objects' screen to select the chosen objects.
20
21	When you click on the 'View All' button on the left side of the screen, you can see the created 'Object Group' objects here.
22	You can ensure control by viewing the created 'Object Group' objects.
23
24	Let's deactivate SpanUnit1 and activate only the objects in Span-2 and Span-3.
25	Only the 3D and finite models of active objects are visible. Additionally, the design reports remaining in the deactivated section will also be deactivated. (This situation can be adjusted with the 'Activation/Deactivation Impact' input.)

2) Design Reset

1
2	To group the Code Checks, first specify a name.
3	To view all superstructure Code Checks, select all support lines and click on the three dots, then choose 'Select References'.
4	Scroll through the 'Select Referencing Objects' screen to select all superstructure Code Checks, then click 'Select'.
5	To remove the selected Code Checks along with the picked Supportlines from the list, click on the three dots, and then click on 'Edit'.
6	Select the rows you want to delete, then click on the three dots, and select 'Delete Row'. Afterward, click on the 'Back' button.
7	Change the 'Activation/Deactivation Impact' input to 'Design Reset'.
8	Let's similarly group all substructure Code Checks belonging to Abut1.
9	Pick Abut1 from the project screen, then click on the three dots and select 'Select References'.
10	In the opened 'Select Referencing Objects' screen, scroll down to mark all substructure Code Checks associated with Abut1, then click on 'Select'. Change the 'Activation/Deactivation Impact' input to 'Design Reset'.
11	To remove the selected Code Checks along with the picked Supportline from the list, click on the three dots, and then click on 'Edit'.
12	Select the row you want to delete, then click on the three dots, and select 'Delete Row'. Afterward, click on the 'Back' button.
13
14	To keep only the Abut1 Code Checks active, deactivate the rest.
15	After the analysis, when you click the design button, the deactivated Code Checks will not enter the design process. Only the substructure Code Checks found in Abut1 will appear in the Summary Report.
