Extract to a file dialog box

Item	Used to
Save in	Select the folder in which the new database is to be extracted to.
File name	Key in the name of the new database to be created or to display a database name selected from the list of displayed files that is to be overwritten.
Save as type	LISCAD files are always created with a SEE extension.
Point Range	Enter a range of point identifiers to be extracted. Those points (including associated lines and polygons) in the range selected will be extracted to the new file. The default range is all points. Note that if a point is selected that is part of a line or polygon which contains unselected points, the unselected points in that line or polygon will also be extracted.
Model	Select whether the current terrain model is to be extracted to the new database. This option is only available if there is a model in the current database. Only the current model that is ON is available to be extracted. Warning: If any points used in the model are in a group that is turned OFF then the extracted model will not be the same. There may be triangles missing due to the missing points.
Long Sections	Select whether long sections are to be extracted to the new database. This option is only available if long sections have been created in the current database. For the long sections to be extracted, the relevent points, lines and alignments used to create the long sections must be displayed in plan view.
Cross Sections	Select whether cross sections are to be extracted to the new database. This option is only available if cross sections have been created in the current database. For the cross sections to be extracted, the relevent alignments used to create the cross sections as well as the cross sections (i.e. Display/Features/Sections) must be displayed in plan view.
Save	Extract the selected objects to a new database and close the dialog box.
Cancel	Close the dialog box without completing the extraction.

If the Block Tool is on, then only those elements which match the block definition will be extracted to the new file. This option is particularly useful for extracting data within a specified boundary. For further information about defining and using blocks, refer to the Block Command and the Block Tool.

Text objects can only be extracted by using a block.
