Opening a File

RocPlane files have a filename extension of .pln4. Older version files have a .pln extension.

To open an existing RocPlane file:

• Click the Open toolbar button or select File > Open.

Whenever a RocPlane file is opened, the analysis is automatically run on the data.

• If the Analysis Type is set to Deterministic, the calculation is almost instantaneous.
• If the Analysis Type is Probabilistic, it may take a few seconds to complete the analysis, depending on the Number of Samples. The progress of the analysis is indicated in the status bar.

Running the analysis each time a file is opened ensures that results can be immediately viewed. The user does not need to select Compute unless the Input Data is changed.
