Hull Surface

Source file: creating-hull-surfaces.htm

The hull surfaces tool combines both the Services Filter and Poisson Surface tools.

To create hull surfaces, click on the Hull Surface button on the Underground ribbon tab, the follow the procedure below.

  1. Select the tunnel data in the project explorer or active view window.

  2. If required, check Handle objects independently. In this case, the tool will generate a separate hull surface from each input point cloud.

    Note:   As with the Centrelines and Services Filter tools, the best results are usually achieved if this is unchecked.

    3. Tip

    If results are unsatisfactory, try either of the following:

    • Run the centrelines tool and ensure the centrelines are satisfactory. See Centrelines.
    • Draw custom-made centrelines with the Line tool. See Line.

    After that, run this tool again using Provide centrelines.

  3. Select the Advanced tab to modify the services filter Settings. Do this particularly if you're not satisfied with results from the default settings.

    4. Note:  Parameters are explained in mouse-over tool tips.

    Tip:  You can also change the output destination in the Advanced tab.

  4. Click OK or Apply.

The hull surfaces will be created and nested inside the container specified in the Destination field on the Advanced tab (scrapbook by default).

When Handle input objects independently is checked, names given to the hull surface containers are derived from the input point cloud names.

Tip

If the results are unsatisfactory, try the following:

  1. Run the services filter alone, using the same advanced filtering settings and data.
  2. Run the Poisson Surface tool on the filtered data with the same Poisson surface settings.

This could help to identify where to adjust settings for a better result.
