Display angle between two lines.
 Command
line : GT_ANGLE
This command determines the two angles (acute and obtuse) between two selected lines. The lines can either be
Line objects or segments from polylines. The computed angle is displayed on the screen.
Select first line: (select the first line segment)
Select second line: (select the second line segment)
The two angles between the line segments are 26.54 degs and 153.46 degs

Compute and display bulge in polyline (arc / fitted) segments
Command
line : GT_BULGE
Polylines that have arc segments in them and those which are curved fitted use bulge value to represent their curvature. These bulge values are stored in the polyline object itself. The
GT_BULGE command helps to print out the bulge values at each of the vertex. This can be useful in various debugging situations.
Command: bulge
Select a polyline:
Bulge at vertex 1 is 0.0894 and Radius is 324.302
Bulge at vertex 2 is 0.1412 and Radius is 133.308
Bulge at vertex 3 is 0.0910 and Radius is 262.438
Bulge at vertex 4 is -0.0778 and Radius is 356.879
Bulge at vertex 5 is -0.0477 and Radius is 448.144
Bulge at vertex 6 is -0.0398 and Radius is 642.951
The
GT_BULGE command creates POINT objects at each bulge location, in a temporary
layer.

Find center of gravity.
Command
line : GT_CGRAV
This command computes center of gravity of masses. The objects that you select should be polyline objects and they should define closed areas. The coordinates of the center of gravity are printed on screen and a point object is created at the CG location.

Compute running distance / perimeter and areas.
Command
line : GT_PERIMETR
This command can be used to compute perimeter and area from picked points or from objects like lines, polylines and circles. The perimeter and area are displayed on the screen as the user picks the points. The enclosing polygon area is displayed at the end of the command.
The
last computed perimeter is stored in memory and can be used in subsequent runs
of this command.

Calculate summed areas of closed area objects.
Command
line : GT_CALCAREA
The GT_CALCAREA command sums up
the areas of all closed polylines, splines and circles. The
area report uses the current unit settings as set in the Area
Annotation Settings (see below). The area can also be annotated at the
centroidal locations in the form of text objects.
Annotation parameters:
Create area annotation:
This
option enables creation of area annotation text.
Create annotation at each centroid: This
option creates each polyline area annotation at its individual centroid position.
Area Annotation
parameters:
DWG units:
Specify the drawing units here. The options available are in, cm, ft,
meters and yards.
Area Units: Specify the units in which the area must be reported.
Available options are dwg, sq.cm, sq.in, sq.ft, sq.m, sq.yards, acres and
hectares.
Annotation
Layer: Specify
the layer in which the annotation is to be created.

Visit (Interactive pan) selected objects.
Command
line : GT_VISIT
The GT_VISIT command is an
interactive pan through a selection of objects. It allows to visit (by panning
each object in the selection to the screen center) all elements of a selection
set. This can be a useful tool in quality control and error checking situations
when you wish to step through a selection of objects and examine them one by
one. The command offers sub-options like Next, Previous and GoTo to navigate
through the selection set sequentially or randomly. There are also options to
set the current zoom factors and highlight color. The GT_VISIT command maintains
an internal pointer to the current object being visited (or borwsed through), so
it is possible to resume the browsing at any point even after the main command
has been exited. To achieve this purpose, two more related commands, GT_NEXT and
GT_PREV are provided to enable an forward and reverse browse through the
selection from the current object position.
Note:
GT_NEXT and GT_PREV commands are related only to GT_VISIT command and therefore
cannot be used independently.

Quick display of entity elevation
Command
line : GT_QUERY
The GT_QUERY command displays the elevation of the
object at the location of the picked point.
Note: GT_Query command is by default not enabled. To
enable it, type GT_Defmacros at the command prompt.

Display horizontal and vertical projected distances.
Command
line : GT_DXY
The GT_DXY command is an extension to the DIST command. In addition to the information given by the DIST command,
GT_DXY also displays the horizontal projected distance between the two picked points, in case of 3D points.
Note: GT_DXY command is
by default not enabled. To
enable it, type GT_Defmacros at the command prompt.
