Figure 3. Import measurement data wizard

3.3.1 Import point cloud data

The

Import point cloud data wizard

supports importing of point cloud data from various

sources. The wizard guides you through the following steps:

1. Select the data source type that suits your data.
2. Select the files that you want to import. Note that importing of multiple files is supported for

some file formats.

3. ASCII import only: Specify the file format.
4. ASCII import only: Specify the content of data columns.
5. ASCII import only: Specify the attributes that will be set for all imported profiles.

In case your point cloud data does not fit one of the standard file formats, but is stored

in an ASCII file, use the flexible ASCII import. This option allows to specify the format

of the source files.

3.4 Export measurement data to PTS

Open the

Point cloud

editor of the construction stage and select the point clouds that should

be exported. Use the

Export to PTS

button from the menu, the toolbar or the context menu

to start the export.

3.5 Edit measured points

Open the

Point cloud

editor of the construction stage containing the point cloud that should

be edited. Select a point cloud and open it (use the Edit button at the bottom of the table or

double-click on the table entry). The

Detail editor

displays the points of the point cloud.

3.5.1 Select points with polygon

Use the select points inside or outside buttons from the menu, the toolbar or the context menu

to start the point selection. To delete the point cloud selection use the

cancel point cloud

selection button

in the toolbar.
