The Selection Tools pertain to a collection of tools used for manipulating and selecting objects.

Menu

Selection
Objektselektion Filter
Command line :
GT_FILTER
The GT_FILTER command provides
the familiar object selection command in Bricscad. With GT_FILTER, you can
build your own powerful filter criteria using object properties,
along with logical operator combinations (AND, OR or NOT).
The GT_FILTER command complements the QSELECT filter tool of Bricscad as
well as the GT_MAKESEL command of GeoTools, both of which are also used
for object selection and filtering, but have different approaches and
interfaces.

Polylinien basierend auf Eigenschaften
Command
line: GT_PLFILTER
Filters polylines based on their properties.
The following properties of polylines can be filtered from the selection set.
| 2D |
3D |
Open |
| Closed |
Fitted |
Arced |
| Splined |
Meshed |
Polyface |
| Z value |
Length |
Number of vertices |
| Area |
Start-End Distance |
|
The length, area, number of
vertices or start-end distances are specified by entering < n, <= n, >
n, >= n, = n, /= n where "n" is the value to check for.
Specify the numeric logical
comparative operator in one of these ways.
< 'Value' - Less than 'Value'
<= 'Value' - Less than or equal to 'Value'
> 'Value' - Greater than 'Value'
>= 'Value' - Greater than or equal to 'Value'
= 'Value' - Equal to 'Value'
/= 'Value' - Not Equal to 'Value'
Enter Length / Area / Z criteria: <= 55.0
This would select all objects with the specified property less than or equal to 55.0
Notes: The Start-End
distances are always measured in slope in the case of 3d polylines. The Z value
check will fail if there is even one vertex in the polyline that fails to meet
the criterion.

3dfaces basierend auf Eigenschaften
Command
line: GT_3DFFILTER
The GT_3DFFILTER command filters 3dfaces based on their derived geometric
properties. The following computations can be performed on 3dfaces and they can
be identified based on the values:
-
Horizontal Projected Area
-
Slope Area of 3dface
-
Horizontal projected perimeter
-
Slope Perimeter of 3dface
-
Coincident Vertexes

Command
line: GT_ESELECT
The GT_ESELECT command allows the Fence, CrossingPoly [CP] and WindowPoly [WP] selection options to be applied automatically along any number of polylines which serve as boundaries for the selection.
Once the boundaries for selection are selected, you can choose the selection method to be applied - which is either Fence,
WPoly or CPoly. The program will then zoom to each boundary and collate the objects meeting the selection criteria into one single selection set. In addition, you can specify how the selection set is to be created.
This command can be used along with the GT_MAKESEL command to build very powerful selection filters.

Command
line: GT_FINDZRNG
Filter selected objects whose Z values fall within a specified range of Z values. This is a useful tool to examine sets of data to see if there is any elevation value that falls outside a given valid band of Z elevations.

Command
line: GT_LASTSEL
The program "remembers" the last created or processed objects and places them in internal memory as well as in the
active [previous] selection set. The active selection may be overwritten at any time using other selection commands, but the last processed results of a GeoTools command can always be brought back to active selection using this command.
