VO ModelPointing
Point parts of a model representing a facility, place, target or vehicle toward another object
Syntax
VO <ObjectPath> ModelPointing "<AttachPoint>" {ModelPointOption} <Value>

Description
The VO ModelPointing command enables you to point parts of a model representing a vehicle, facility, place, or target toward another object, such as the Sun or Earth, by indicating the attach point and target.
"<AttachPoint>" are determined by the attach points specified in the object's model file.
Not all models have AttachPoints. You must be using a model with AttachPoints to use the VO ModelPointing command successfully.
When used in conjunction with BatchGraphics, this command cannot be used in the same batch as the VO Model command or the model pointing may not be accepted.
| {ModelPointOption} | <Value> | Description |
|---|---|---|
| Target | {TargetOption} | Use {TargetOption} to indicate the target object to which a facility, place, target, or vehicle model will point. Valid values for {TargetOption} are described below. |
| Intervals | {IntervalOption} | Use {IntervalOption} to define intervals during which an object model will point toward a selected target. Valid values for {IntervalOption} are described below. |
| None | N/A | Pointing is disabled for the AttachPoint. |
The "<AttachPoint>" must already be set as targeted for the object, unless the {IntervalOption} is Add or Load, in which case the attach point will be added if it doesn't yet exist.
{IntervalOption} can be:
| {IntervalOption} | <Parameters> | Description |
|---|---|---|
| Clear | {TargetOption} | Removes the first display interval for the target specified using the {TargetOption}. |
| ClearAll | [{TargetOption}] | Removes all display intervals for the target specified using the {TargetOption}. If you do not specify {TargetOption}, all intervals for all target options are removed. |
| Add | <NumIntervalPairs> "<IntervalStart>" "<IntervalStop>" {TargetOption} ["<IntervalStart>" "<IntervalStop>" {TargetOption}...] | Adds intervals with Targets to the list of times. The number of "<StartTime>" "<StopTime>" {TargetOption} value sets entered must equal the <NumIntervalPairs> specified. |
| Replace | "<IntervalStart>" "<IntervalStop>" {TargetOption} "<IntervalStart>" "<IntervalStop>" | Replaces a single interval matching the first start, stop, target with the second start and stop time. The target stays the same. |
| ReplaceAll | <NumIntervalPairs> "<IntervalStart>" "<IntervalStop>" {TargetOption} ["<IntervalStart>" "<IntervalStop>" {TargetOption}...] | Clears ALL interval lists and replace them with those specified here. The number of "<IntervalStart>" "<IntervalStop>" {TargetOption} value sets entered must equal the <NumIntervalPairs> specified. |
| Load | {{TargetOption} | FromFile} "<FilePath.int>" | Replaces or create the interval list for the {TargetOption} specified by loading a file that specifies interval pairs.
Enter FromFile instead of {TargetOption} to have the target(s) read from the interval file. The file must be in the STK interval list file format and end with a .int extension. "<FilePath>" is the path to a file on your local drive. |
| Import | {TargetOption} "<TimeComponent>" | Import the specified Interval or Interval List time component.
For information about "<TimeComponent>", see Component Specification. |
{TargetOption} can be:
| {TargetOption} | Description |
|---|---|
| Sun | Points an object at the Sun. |
| <CBName> | Specify another object's central body name. The default value is Earth. |
| LLA <CBName> <Latitude> <Longitude> <Altitude> | Points to a specific lat, lon, alt on a central body. Enter <Latitude> and <Longitude> in degrees. <Latitude> must be between -180 and 180 degrees. Enter <Altitude> in meters, larger than the minimum altitude defined for the central body. |
| <TruncObjectPath> | Use this to point a model toward another object in the scenario. |
| Slew | Interpolates pointing over a specified interval to point from the object in the previous interval to the object in the next interval.
This option is only valid if you ues {TargetOption} in conjuction with the Intervals {ModelPointOption}. |
