Selects a subset of keypoints or hard points.
Type
Label identifying the type of select:
S
—
Select a new set (default).
R
—
Reselect a set from the current set.
A
—
Additionally select a set and extend the current set.
U
—
Unselect a set from the current set.
ALL
—
Restore the full set.
NONE
—
Unselect the full set.
INVE
—
Invert the current set (selected becomes unselected and vice versa).
STAT
—
Display the current select status.
The following fields are used only with Type
=
S, R, A, or U:
Item
Label identifying data. Valid item labels are shown in the table below. Some items also require a component label. If
Item
= PICK (or simply "P"), graphical picking is enabled and all remaining command fields are ignored (valid only in the GUI). Defaults to KP.Comp
Component of the item (if required). Valid component labels are shown in the table below.
VMIN
Minimum value of item range. Ranges are keypoint numbers, coordinate values, attribute numbers, etc., as appropriate for the item. A component name (as specified on the CM command) may also be substituted for
VMIN
(VMAX
andVINC
are ignored). IfItem
= MAT, TYPE, REAL, or ESYS and ifVMIN
is positive, the absolute value ofItem
is compared against the range for selection; ifVMIN
is negative, the signed value ofItem
is compared. See the KLIST command for a discussion of signed attributes.VMAX
Maximum value of item range.
VMAX
defaults toVMIN
.VINC
Value increment within range. Used only with integer ranges (such as for keypoint numbers). Defaults to 1.
VINC
cannot be negative.KABS
Absolute value key:
0
—
Check sign of value during selection.
1
—
Use absolute value during selection (sign ignored).
Notes
Selects a subset of keypoints or hard points. For example, to select a new set of keypoints based on keypoint numbers 1 through 7, use KSEL,S,KP,,1,7. The selected subset is used when the ALL label is entered (or implied) on other commands, such as KLIST,ALL. Only data identified by keypoint number are selected. Data are flagged as selected and unselected; no data are actually deleted from the database.
This command is valid in any processor.
For selections based on non-integer numbers (coordinates, results, etc.),
items that are within the range VMIN
-Toler
and VMAX
+ Toler
are selected. The default tolerance Toler
is
based on the relative values of VMIN
and VMAX
as
follows:
If
VMIN
=VMAX
,Toler
= 0.005 xVMIN
.If
VMIN
=VMAX
= 0.0,Toler
= 1.0E-6.If
VMAX
≠VMIN
,Toler
= 1.0E-8 x (VMAX
-VMIN
).
Use the SELTOL command
to override this default and specify Toler
explicitly.
