Pinned datums

Datums can be Pinned to the location at which they were created using RMB>Pinned.

Pinned Datums will move if their creation references are moved.

If a DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. is created and subsequently moved from its original (created) position (with respect to its creation references) RMB>Pinned will be grayed out.

The following apply to all pinned datums

• Pinned datum icons in the tree are highlighted to distinguish them from normal

• Ctrl+drag to copy in the MoveA tool used to translate or rotate geometry. tool works for all pinned datums. The original datum remains pinned but the new copy is unpinnable.

• DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. Planes and Axes are now automatically unpinned when they can no longer be constructed from the reference objects. For example, when a reference face is changed from a plane to a cylinder.

• The DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. PlaneConstruction geometry consisting of a flat surface. Planes can be used for a 2D sketch, section view of a model, a neutral plane in a draft feature., LineA straight line, arc, or spline drawn in Sketch mode or on a layout plane. Lines have length but no area. When you pull a sketch into 3D with the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool, lines become edges., and PointSingle location in the sketch grid. 2-D object that has no height, width, or length. The origin, an axis, and a vertex are examples of points. Use the Point tool to sketch a point on the sketch grid. Points are useful as a dimensional reference, for splitting, and for creating a point on a line or curve through which you want to draw a three-point circle. tools are sticky (they stay on until you enter another tool) like normal tools.

• If any of a Pinned DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects.’s references are deleted, the system forces the datum to be unpinned. The datum will not be placed with respect to the remaining references. This applies to Planes, Lines, and Points.

• DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. Planes, Lines, and Points that are constructed exclusively from other pinned datums become pinned by default. For example, a datum axis will be pinned by default if it is constructed from a point pinned to a face.

• The MoveA tool used to translate or rotate geometry. handle is disabled when all selected objects are pinned datums (axes, planes). Since they are pinned, these objects cannot be Moved. If unpinned datums, or other objects, are included in the selection, the MoveA tool used to translate or rotate geometry. handle is enabled, but the pinned datums will not MoveA tool used to translate or rotate geometry.. To allow copying, the MoveA tool used to translate or rotate geometry. handle becomes enabled when the Ctrl key is pressed.

The following apply to pinned datums in components

• You can Cut/Copy/Paste by parent component.
• You can set the Visibility by parent component.
• NoteAnnotation placed on a design, drawing sheet, or 3D markup. Notes contain text or symbols that you insert and can be connected to geometry by a note leader. that when pinned datums are moved to a new component, they become unpinned and subsequently unpinnable
• Datums can only be pinned if All of the references are in the same component. Allowing references from multiple components can result in unintentional AssemblyHierarchy of components and subcomponents showing relationship within a design, as shown in the Structure tree. In manufacturing, a unit fitted together from manufactured parts. See Assembly tool, Component-like constraints.

Pinned Planes

• In the graphics area, Pinned Datums are also given a green color and they have their corners rounded. The image here shows the plane selected to emphasize the color.
• The pinned datum Reference is also highlighted when the plane is selected.
• If any of the pin references are deleted, the plane is automatically unpinned.
• You can NOT pin datum planes created from temporary references (using ALT+SHIFT.)
• Only DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. Planes that are NOT moved from their original position can be pinned. Planes moved away, and then back to their creation references, CANNOT be pinned.
• Planes created using the Build PlaneConstruction geometry consisting of a flat surface. Planes can be used for a 2D sketch, section view of a model, a neutral plane in a draft feature. tool guide cannot be pinned. The references used in creating these planes are temporary and are not remembered outside of the tool.

Pinned Axes

• Un-pin a DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. LineA straight line, arc, or spline drawn in Sketch mode or on a layout plane. Lines have length but no area. When you pull a sketch into 3D with the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool, lines become edges. if any of the references are deleted.
• Pinned axes are given a green color to distinguish them from normal axes.
• Pinned Axes attached to pinned datum points on faces will adjust when the faces are edited with Tweak FaceSide or other surface of a solid. Some examples are the inside surface of a hole or the six sides of a rectangular solid. See Surface., PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid.>OffsetDistance an edge, segment, or curve is moved or copied., MoveA tool used to translate or rotate geometry., Bend, etc. 
• Axes created using the Build LineA straight line, arc, or spline drawn in Sketch mode or on a layout plane. Lines have length but no area. When you pull a sketch into 3D with the PullTool used to distort or deform geometry. Use the Pull tool to offset, extrude, revolve, sweep, draft, and blend faces; or to round, chamfer, or extrude edges. When converting a sketch to 3D, pulling a line creates a surface and pulling a surface creates a solid. tool, lines become edges. tool guide cannot be pinned. The references used in creating these planes are temporary and are not remembered outside of the tool.

Pinned Points

• Currently pin to an existing point/vertex, or to the midpoint between two other points.
• FaceSide or other surface of a solid. Some examples are the inside surface of a hole or the six sides of a rectangular solid. See Surface. and Edge3D object composed of a single outside boundary of a feature. A line sketched in 2D becomes an edge when you pull your sketch into 3D. point connections have been added.
• You can now box-select Points
• Pinned DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. Points now store their latest location to ensure proper placement if the pin reference becomes invalid by deletion or geometry change.
• 3D DatumObject that is assumed to be an exact size and shape, and be in an exact location, that is used to locate or establish geometric relationship of other objects. Points can now be moved with the MoveA tool used to translate or rotate geometry. tool if they are not pinned.
• When you Bend a face that has pinned datum points, the points follow the face at a well-chosen location.
