Using the plug-in

1. Open your ETABS model (.edb) in ETABS v22

2. Launch the plug-in via the menu: Tools > Plugins > CalcTree

3. The CalcTree plugin window will appear, showing a structured tree view of available model tables. These are grouped by category — such as Geometry, Assignments, Loads, and more — for easy navigation.

4. Select the table(s) you wish to upload by clicking on them in the table tree view. Selected tables will highlight blue, and then list out in the 'selected tables' field below.

5. Add an API key

6. Before sending your data, choose how you would like the plug-in to upload it to CalcTree. You have three options:

   1. Send to an Existing Page Paste the URL of an existing CalcTree page into the relevant field. → Your data will be uploaded directly to that page.

   2. Duplicate a Template Page

      • Paste the URL of a template page into the relevant field.

      • (Optional) Enter a custom name for the new page in the relevant field.

      • (Optional) Provide a parent page URL in the relevant field if you'd like the new page to be created under a different section. → If left blank, the new page will be created in the same location as the original template.

7. Once your upload method is selected and fields are filled, click Send to CalcTree to complete the upload

Using the data in CalcTree

Once data tables have been sent to CalcTree, they will appear under the 'Uploaded files' toggle in the Integrations panel of the page you sent the data to.

The data, in the form of CSVs, can be consumed in your Python script for additional processing, calculations, and management of how you wish the data to be displayed on the page.
