Go to the 'Plate Girder' object in the workflow.

3

Click Click on 'DATA' located in the bottom-middle section of the screen.

You will see that a spreadsheet opens.

3

Click on 'Plate Girder' under 'Superstructure' in the workflow.

You will see all the girders and their parameters in the spreadsheet for the project.

4

To change the web depth parameter of the 'G4' girder, click on the 'Web Depth' input cell of the girder you want to change the web depth. Then, click .

When you click on the cell, you will see three dots appear to the right of the cell.

5

Click on the three dots that appear on the right side of the cell. After that, click on 'Edit (Spreadsheet)'.

In the newly opened spreadsheet, we can define the 'Web Depth' parameter as station dependent.

After the definition is done,

click the 'Back'

icon (marked in blue) to apply the changes to the project.

Example model to experience the steps from 1 to 7

Example Model : https://openbrim.org/platform/?application=app&prj=objida5tdt4qqgc9xvelekk7x&active=GraphicsView Click on 'DATA' located in the bottom-middle section of the screen.

You will see that a spreadsheet opens.

2

Click on the 'Support Line' object in the workflow to set the skew angle.

3

When the skew angle value of 'Abut 1' is zero, it appears like this.

4

When the skew angle of 'Abut 1' changes, it appears like this.

As seen, the cross-frames are not aligned according to the support line.

5

• To align the skew angle of the cross-frame with the support line, click on the three dots to the right of the skew angle input cell of the support line.

• Then, click on 'Copy Parameter'. Now, the value of the skew angle has been copied parametrically.

• The parameter we copied exactly is: Abut1.s_skew

• Therefore, the copied value will also change whenever the skew angle of ‘Abut 1’ changes.

6

Go to the cross-frame objects where the skew angle will change. Click on the three dots to the right of the 'Skew Angle' input cell.

(Instead, after clicking on the cell, you can also paste it using CTRL+V.)

7

You no longer need to manually change the skew angles of cross-frames every time the support line skew angle changes. The skew angle value of cross-frames will now be parametrically equal to the skew angle value of the support line.
