This describes the Method Input section as it differs for the various Axis Method buttons.
When the Datum Type is Axis, the Axis Method can be any one of the following. The contents of the subsequent Method Input section depends on the Axis Method, too.
Axis Method is CAD Cylinder/Cone
- by identifying a cylinder or cone on a CAD object.
Axis Method is Best Fit
- by selecting an almost-linear region on which the software calculates
the best fit for an axis.
Axis Method is Intersect
- by defining the intersection of two planes.
Axis Method is Plane and Point
- by defining a line that intersects a point and is perpendicular to a
plane.
Axis
Method is Two Points - by defining two points.
When Axis Method is CAD Cylinder/Cone, the Method Input section is:
Instruction: “Select cylindrical or conical face on CAD object.”
Include All Co-Axial Faces checkbox - whether to consider additional cylinders or cones that share the same rotational axis as the defining cylinder or cone to be additional defining cylinders or cones of the datum.
Apply button - generates an image of the datum in the Viewing Area.
Next button - stores the datum in the Current Datums list and the Model Manager.
When Axis Method is Best Fit, the Method Input section is:
Instruction: “Select region for best fit.” Select one of the following radio buttons, then select a construct in the viewing area. The axis datum will be best-fit to the one construct you select.
Rotational Axis radio button - the axis datum will be best-fit to the rotational axis of the construct you select.
Cylinder radio button - the axis datum will be best-fit to the axis of the cylinder you select.
Cone radio button - the axis datum will be best-fit to the axis of the cone you select.
Apply button - generates an image of the datum in the Viewing Area.
Next button - stores the datum in the Current Datums list and the Model Manager.
When Axis Method is Intersect, the Method Input section is:
Instruction: “Specify two intersecting planes.”
Plane 1 dropdown (XY, XZ, YZ, and existing datum planes) - specifies first plane.
Plane 2 dropdown (XY, XZ, YZ, and existing datum planes) - specifies the second plane, whose intersection with the first plane defines an axis datum.
Apply button - generates an image of the datum in the Viewing Area.
Next button - stores the datum in the Current Datums list and the Model Manager.
When Axis Method is Plane and Point, the Method Input section is:
Instruction: “Specify plane and point.”
Plane 1 radio button and dropdown (XY, XZ, YZ, and existing datum planes) - specifies a plane to which the axis datum is perpendicular.
Point radio button, Five buttons for point selection technique (surface, center, vertex, datum, curve), and X,Y,Z - specifies a point that the axis datum intersects.
Apply button - generates an image of the datum in the Viewing Area.
Next button - stores the datum in the Current Datums list and the Model Manager.
When Axis Method is Two Points, the Method Input section is:
Instruction: “Specify two points.”
Five buttons for point selection technique (surface, center, vertex, datum, curve) -
First Point radio button and X,Y,Z - specifies the first point that the axis datum intersects
Second Point radio button and X,Y,Z - specifies the second point that the axis datum intersects
Apply button - generates an image of the datum in the Viewing Area.
Next button - stores the datum in the Current Datums list and the Model Manager.
