By Offsetting from Two Objects |
Scroll |
The option to specify a point By displacements from two objects
is used if the displacement (linear or angular) of the point from two reference objects is known.
In the general case, the point is located on the arbitrary surface and its offset is defined by distances to it from two flat objects. More details on object types...
Flat objects must meet the following requirements:
•not parallel to each other,
•the line of intersection of their planes is not parallel to the surface (or the generating surface) on which the point is located.
In addition, the following particular cases are possible:
•if the point is located on the plane face, you can use a straight-line edge as its reference object; in this case, offset is calculated from the plane passing through this edge perpendicular to the flat face;
•if the point is located on the revolution surface (other than spherical), you can specify angular offset from the plane passing through the axis of the surface (in this case, offset from the second object will be linear); in order to define such plane, you can specify a flat object coinciding with it or a straight-line edge lying in it.
The name of the object from which the point offset is calculated is automatically defined by the system and displayed on the Parameter panel in the Object 1/Object 2 group of elements in the Object field. Arrows of the positive offset calculation direction are displayed in the graphic area.
1.Specify a different object (objects) from which offset of the point should be calculated, if required.
2.Set the offset value from the selected objects in the fields Distance1/Angle1 and Distance2/Angle2.
3.If you build a point on the surface of rotation and select a plane passing through the axis of rotation as the reference object, you can change the type of the linear parameter to angular and back using the Parameter group of buttons:
Linear/Radial: type of displacement is linear.
Angular: displacement type is angular.

You can only specify such an object as the second reference object if it can give a finite number of points with the selected surface and the first reference object. |
4.If several points can be built by offsetting from the selected objects, they will be displayed alternately when clicking the Next result
and Previous result
buttons on the Parameter Panel. Specify the required option.
