Click on the Design tool.

Create a new design and go to FUNCTIONS- Import.

By default, CSV import is selected. Click on Choose file button and open a CSV or TXT-formatted file containing your points. Once you've selected a file, a summary of how many valid rows were found will be displayed. Here, you can choose whether the points should be connected to form a line.

Choose the corresponding fields in the file for N, E, and H, then click Confirm.

The points are created and are now visible in the scene. To save the geometry with the points, click on the save icon or use Ctrl+s.

Give the geometry an optional name and click Confirm.
