  • This command makes it possible to selectively display and work with pointsusing  filter expressions. As soon as the command is invoked any previously existing filters are deleted. Coordinate data may be used in the expressions as well as attribute fields. The standard coordinate field names for point data are XPT,YPT and ZPT.

Complex Filter Expressions and Scripting

You can emulate the effect of multiple-line filter expressions in scripts by joining expression parameters with "AND". For example, the following scripted command

Dm.parseCommand(“filter-points ‘AU > 0.5 AND’ ‘M4DDESC =2’ ‘’);

Represents the following expression filter:

AU > 0.5 AND
M4DDESC = 2

Note the third parameter (empty single quotes). This is used to indicate that no further expressions will be specified.
