Info

To experience aligning the cross-frame skew with the support line's skew, please follow the instructions below:

1

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

This will open a spreadsheet.

→ 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 'Support Line' under 'Bridge Geometry' in the workflow to access the skew angle parameter.

3

→ To change the skew angle of 'Abut1', click on the corresponding cell (mark in red).

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 “(blue star)” button located in the top right corner of the screen.

Once you click on an object, pressing “(blue star)” will allow you to rotate around that object. To rotate an object, hold down the left mouse button and drag it.

When the skew angle value of 'Abut1' is set to zero, it will appear as shown on the right-hand side.

5

When the skew angle of 'Abut1' is set to '-15' degrees, it will appear as shown on the right-hand side.

As observed, the cross-frames are not aligned with the support line.

To parametrically align the skew angle of the cross-frame with the skew angle of the support line, you can follow these steps:

  1. Copy the skew angle value of the support line using the "Copy Parameter" function.

  2. Paste this parametric expression into the skew angle value of the cross-frame.

  3. By doing so, the skew angle of the cross-frame will be dynamically linked to the skew angle of the support line.

6

→ Click on the skew angle cell of 'Abut1'.

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

→ Then, click on the three-dots that appear on the right side of the cell.

→ From the options provided, select 'Copy Parameter'.

Now, the value of the skew angle has been copied parametrically.

The parameter copied exactly is: =Abut1.s_skew

7

→ Expand the 'Cross Frames' section under 'Superstructure' in the workflow.

→ Then, click on 'Cross-frame K Top' to access its parameters.


8

After clicking on the skew angle cell of 'CFTK1', you will see three dots appear to the right of the cell.

→ Click on the three dots to access additional options and select 'Paste' from the menu.

After clicking on the cell, you can also paste the copied parameter by using the keyboard shortcut CTRL+V.

9

→ Perform the paste operation for 'CFKT28' and 'CFKT29' in the same manner as before.

As observed, the skew angles of the cross-frames have now been aligned with the support line.

You no longer need to manually adjust the skew angles of the cross-frames whenever the skew angle of the support line changes. The skew angle values of the cross-frames are now parametrically linked to the skew angle value of the support line.

Tip

Aligning the cross-frame skew with the support line's skew is completed.

Info

Additionally, to align the roadway with the skew angle, please follow the instructions below:

11

→ To align the roadway with the skew angle of the support line, expand the 'Superstructure Attachments' section in the workflow and click on 'Roadway' to access the parameters related to the roadway alignment.

→ Then, click on 'Edit' from the three-dot menu on the right side of the 'Roadway Dimensions' cell.

→ Paste the skew angle copied from 'Abut1' into the 'Skew' parameter at zero station, as shown in step 8.
