OpenBrIM Parametric Modeling

...

Info
This section will showcase the practical application of the OpenBrIM Platform's cloud-based parametric approaches, emphasizing their ability to enhance the user's modeling experience smartly.

Info

To experience modifying web dimensions, please follow the instructions below:

In the following instructions, we will modify the web depth parameter through the spreadsheet, and both the 3D model and FEA model will be updated accordingly. Please refer to the following instructions for guidance.
1	→ Click on the 'DATA' button located in the bottom-middle section of the screen. This will open a spreadsheet. Panel panelIconId 1f4a1 panelIcon :bulb: panelIconText 💡 bgColor #FFFAE6 → To adjust the height of the spreadsheet, click and hold the 'DATA' button with the left mouse button, then drag it to the desired position. → To close the spreadsheet, simply click once on the 'DATA' button.

2	→ Click on 'Plate Girder' under the 'Superstructure' section in the workflow tree. This action will display all the project girders and their corresponding parameters in the spreadsheet

for the project

	Panel panelIconId 1f4a1 panelIcon :bulb: panelIconText 💡 bgColor #FFFAE6 You can zoom in and out by using the scroll wheel of your mouse. To move around, press and hold the scroll wheel while moving your mouse. If the bridge is out of view, you can realign the bridge by clicking on the “” button located in the top right corner of the screen. Once you click on an object, pressing “” will allow you to rotate around that object. To rotate an object, hold down the left mouse button and drag it.	Image Modified
4	→ The Finite Element model appears as shown on the side with the current web depth (84 inches). → To modify the web depth parameter of the 'G4' girder, click on the corresponding 'Web Depth' cell of the girder in the spreadsheet. → Next, enter the value of 55 inches as the web depth in the cell.

Panel panelIconId 23f3 panelIcon :hourglass_flowing_sand: panelIconText ⏳ bgColor #FFFAE6 Updating the dimensional change in the 3D model and Finite Element model will take approximately 10 seconds. When a user makes changes to a parameter in the spreadsheet, the 3D Model/FEA Model, CAD drawings, and dynamic reports such as quantity reports are automatically updated to reflect the impact of the new parameter. OpenBrIM triggers a compilation process using your inputs to generate these updated outputs.
5	→ The new Finite Element model appears as shown on the side with the updated web depth.	Image Modified
6	→ Open the sliding menu again by clicking on the icon in the top left corner, and then click on 'MODEL' to switch to the 3D view.	Image Modified
7	→ You can see the changes in both the 3D view and the Finite Element model in the visual on the side.	Image Modified
Info

It is also possible to define girder dimensions as station-dependent. To experience modifying web dimensions, please follow the instructions below:

8

→ To modify the web depth parameter of the 'G4' girder station-dependent, click on the corresponding 'Web Depth' cell of the girder in the spreadsheet.

Once you click on the cell, you will notice three-dots appearing to the right of the cell.

9

→ Click on the three-dots that appear on the right side of the cell. Then, click on 'Edit (Spreadsheet)' from the options that appear.

10

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

→ Once you have made the desired changes, click on the 'Back' icon (marked in blue) to apply the changes to the project.

Panel panelIconId 1f449 panelIcon :point_right: panelIconText 👉 bgColor #FFFAE6 To parametrically align the skew angle of the cross-frame with the skew angle of the support line, you can follow these steps: Copy the skew angle value of the support line using the "Copy Parameter" function. Paste this parametric expression into the skew angle value of the cross-frame. By doing so, the skew angle of the cross-frame will be dynamically linked to the skew angle of the support line.
