Description:
Parameter | Value Type | Description |
|---|
geometry_name | An Existing Geometric Entity | Specifies an existing geometry. |
base_marker | An Existing Marker | This parameter is used to specify a marker whose position will be frozen in the view as the model animates |
curve_type | Curve_type | Specifies the type of curve to be created, either bspline or polyline |
close | Yes_no_auto | Causes the info window to close down. |
analysis_name | An Existing Analysis | Specifies an existing analysis |
Extended Definition:
1. A trace that follows a curve creates a two-dimensional spline. The point can move in any direction relative to the part on which the trace was created. Adams View creates the curve in the xy plane of the base marker(the marker on the part on which the trace was created). Adams View assumes the circle is parallel to the plane or the cylinder is perpendicular to the plane, and that the motion is in this plane.
2. You may identify geometry by typing its name or by picking it from the screen.
If the geometry is not visible on the screen, you must type the name.
You may also find it convenient to type the name even if the geometry is displayed.
If geometry is available by default, you may identify it by entering its name only. If it is not, you must enter its full name. To identify geometry under another model, for instance, you may need to enter the model and part names as well. For example, you may specify arc 'end' on part 'arm' in model 'susp' by entering ".susp.arm.end". If you type a "?", Adams View will list the geometrys available by default.
You must separate multiple geometry names by commas.
If the geometry is visible in one of your views, you may identify it by picking on any of the graphics associated with it.
You need not separate multiple geometry picks by commas.
3. base_marker is particularly useful when a relatively small object undergoes both small configuration changes as well as large overall gross motion. For example, the flight path of a jet is very large over time relative to the motion of the control surfaces on the jet. In this case selecting the BASE_MARKER to be on the jet would be appropriate.
This parameter can be used with the CAMERA_REF_MARKER to create a different effect on the viewing direction. When the CAMERA_REF_MARKER and the BASE_MARKER are specified together, the viewing direction is "from" the CAMERA_REF_MARKER position "to" the BASE_MARKER position. In addition the "up" direction of the view is computed based on the direction of the CAMERA_REF_MARKER "y" axis (i.e. the y axis is projected into a direction perpendicular to the viewing direction defined by the two markers). This viewing direction is recomputed between each frame of the animation. This feature allows the effect of watching an object come from a distance pass by and proceed into the distance.
Specifies an existing marker.
You may identify a marker by typing its name or by picking it from the screen.
If the marker is not visible on the screen, you must type the name.
You may also find it convenient to type the name even if the marker is displayed.
If you created the marker by reading an Adams data set or graphics file, the marker name is the letters MAR followed by the Adams data set marker ID number. The name of Adams MARKER/101 is MAR101, for example. If you created the marker during preprocessing, you gave it a name at that time.
If a marker is available by default, you may identify it by entering its name only. If it is not, you must enter its full name. To identify a marker under a different part, for instance, you may need to enter the model and part names as well. For example, you may specify marker 'pivot' from model 'links', part 'lower_arm' by entering ".links.lower_arm.pivot". If you type a "?", Adams View will list the markers available by default.
You must separate multiple marker names by commas.
If the marker is visible in one of your views, you may identify it by picking on it.
You need not separate multiple marker picks by commas.
4. Any text that was in the info window while open, will be flushed out. The next time the info window is opened, only the new text will be present.
Closing the info window does not change its size. The next time the info window is opened, its size will be the same as the previous time.
All scroll positions are returned to the first line in the info window.
5. You may identify a analysis by typing its name or by picking it from the screen.
An analysis may be picked from the screen if you have read an Adams Graphics file, and use the GRAPHIC_RESULTS command to display it. If the analysis is not visible on the screen, you must type the name. You may also find it convenient to type the name even if the analysis is displayed.
You may have explicitly named the analysis when you created it by reading one or more Adams output files. By default, the name of the analysis is the root name of the Adams output files. If you created the analysis by reading an Adams Graphics file, for instance, the analysis name is the name of the graphics file without the '.gra' extension.
You may get a list of analysis by typing a "?" in response to a parameter that requires an analysis name be entered.
You must separate multiple analysis names by commas.
If the analysis is visible in one of your views, you may identify it by picking on any of the graphics associated with it.
You need not separate multiple analysis picks by commas.
