On the 3D Model tab, Work Features panel, use Point or Grounded Point in a part file to select model vertices, edge and axis intersections, intersections of three nonparallel faces or planes, and other work features as work points. You can also create work points as input to other work feature commands that require you to select a point.
In an assembly file, use the Point commands on the 3D Model tab. Work points can be created at the intersection of part faces, edges, vertices, and work geometry that span hierarchical levels in the assembly.
Work points can be placed on holes and cuts in part faces, model surfaces, construction surfaces, and base surfaces. When Loop Select Mode is active, you can place a work point on one or more closed loops.
- Mark shaft and pattern centers
- Define coordinate systems
- Define planes (three points)
- Define 3D paths
In a part file, use the Grounded Point command. When you create a grounded work point in a part file, the 3D Move/Rotate command is available so that you can specify certain operations relative to the grounded work point. Or, use the 3D Move/Rotate option on the context menu later to reposition the work point.
- The work point position is originally determined by the geometry you selected to create it. When you select Ground, the relationship to the selection geometry is removed. The work point remains fixed in space, even if the selection geometry is moved or resized.If you clear the check mark on the Ground menu option, the associative relationship is restored. Changes to the selection geometry reposition the work point.
- When you use 3D Move/Rotate to edit a grounded work point, the relationship to the original selection geometry is permanently removed. You cannot restore an associative relationship to the original geometry used to create the work point.
- Select the 3D Move/Rotate option.If geometry was used to position the work point, it is no longer associated to the work point. The work point remains grounded.
- Select the Redefine Feature option.The work point becomes associative to new geometry that you select. Changes to the geometry reposition the work point.
