Problem

I have a complete model in SACS and I want to convert the same to STAAD. What is the procedure?

Solution

For this activity Bentley has launched iTwin synchronization tool (free from Bentley) where a user can convert the SACS model to a corresponding STAAD model. Now, let us walk though this procedure with a sample model for file based work flow.

Step 1:

Select the iTwin Services button in Engineering Applications

Step 2:

A new window will pop up with a question of pushing or pulling a file. Here, we are trying to send the file to the ISM platform, and hence we will opt for “Push to file” option. If we already have an existing dgn file which we want to convert into SAC model, we would have opted for the “Pull to file” option.

Step 3:

When we trigger the “Push” option, the ISM platform will create a *dgn file. It will ask the user to save the file at a designated location in the system, when the “New” button is clicked.

Once this activity is done, you will see a quick notification as

Step 4:

Now, open a black STAAD model. Make sure the unit of SACS and STAAD remain consistent. Go to the ISM part and select “Create New Model from ISM Repository”.

Step 5:

Once selected, it will ask for the ISM path, where you kept the *dgn file saved by pushing the same from the original SACS model. After you provide the path, click on the Run button at the top left corner of the window.

Step 6:

During the process a window “Workflows” will appear. You need to close this without any change.

Step 7:

Once you close the “Workflows”, you will see the original model is open in iTwin Analytical Synchronizer. Click on the “Select All” option and then “Update”.

Step 8:

Once done, the process of pulling the file into STAAD will start with a pop up.

Step 9:

In your model, there may be some built up sections, and their correspondences are not possible in STAAD. So, you need to define these sections in STAAD Shape tables or you can “Cancel”. If you “Cancel”, then the members in the STAAD model, corresponding to the Section would not have any sectional properties and again in the STAAD model you have to define them. While the conversion was going on, STAAD would show a message as below.

Thus, the final conversion will be possible.

Please note, during the conversion, only model geometry can be transferred. The ISM platform does not allow any load migration and you need to assign the loads in the new STAAD file again, based on STAAD syntax. Also, at this moment, ISM does not support any Plate migration.
