Annotations provide both graphical controls for the placement size and orientation of the text element within the graphics and contain all the tolerance and datum reference information for a particular check.
Type. This field identifies the type of check represented by the annotation.
Name. The datum letter used as an identifier in the annotation (currently support single and double letter annotations and will automatically exclude I,O,Q for ASME).
These controls are used with the Inspection > Inspect process described in the Workflow Section.
MeasurementProfileName. Controls the measurement mode set when inspection is initiated for this check.
MeasurementToolName. Controls the tooling set when inspection is initiated for this check.
The Feature Type section provides a list of the associated objects for the annotation. It also allows you to re-select the associated features and define additional reference objects as needed. You must select either CAD faces or SA objects.
SA Object. The selected SA objects define both the annotation placement and the features evaluated as part of the check.
CAD Feature. The selected CAD faces define the annotation placement and the features evaluated as part of the check.
GRs. The selected GR-Features (Geometry Relationships) used to define the annotation placement and the features evaluated as part of the check. The Nominal geometry from the selected GR-feature will be used.
SA Offset Object. SA Offset Objects provides directional reference information or alignment restrictions for surface datums.
Auto Detect CAD Faces. Profile checks can have this option enabled which allows all measured faces to be evaluated under the specified tolerance. This provides a convenient means to apply a global tolerance to a part.
Is Slot. This check box designates this feature as a slot which triggers a separate evaluation process.
These controls provide the ability to redefine the text size, placement and orientation in the job.
View. The View defines the saved orientation of annotation text.
Height. The Text Height defines the height of the annotation text. This is expressed in job units.
Text Rotation. The Text Rotation defines the rotation in the current view.
With the annotation editor open the graphical annotation can be moved and placed in a position that is easy for the user to read. The annotation leader line is defined using a click-point on the first surface face or SA Object selected when that feature is assigned in the annotation. To move the annotation simply select the annotation in the graphics by left-clicking the annotation. While holding the left mouse button the annotation can be moved in the plane of the screen. Using orthogonal views can help to precisely locate annotations in 3D. The view can be change under the View parameter in the annotation editor. Controls at the bottom of the annotation editor help in fine tuning the position and orientation of the annotation.
Rotates the annotation box 90 degrees counter clockwise.
Rotates the annotation box 90 degrees clockwise.
Mirrors the annotation box.
Straightens the leader line normal to the selected surface face.
TextAbove. Allows a user to display text just above the reference frame for a check.
TextBelow. Allows a user to display text just below the reference frame for a check. The TextBelow field can also be used to isolate a check from a simultaneous evaluation using text such as SEP REQT.
Certain Alt + Number entries can be used to add symbols to this text line. A brief list of these symbols includes the following:
Alt + 0176. Will produce the degree symbol °
Alt + 0177. Will produce the plus & minus symbol ±
Alt + 0226. Will produce the diameter symbol Ø
When a datum/check is added to a cylindrical feature the following additional controls will be provided.
Cylinder Mode. Allows for selection between hole and pin cylinder evaluations. It is used to properly define probing offsets.
Axial Extent Mode. Provides control of the way full cylinder evaluations are performed (see “Cylinder Evaluation Methods.” .
Auto Full Cyl Eval. It also provides control of the way full cylinder evaluations are performed (see “Cylinder Evaluation Methods.
When working with offset objects and surface datums or pattern features it can be important to provide a good starting alignment for the evaluation to ensure the best solution is found.
Custom Initial Alignment. This field provides the ability to reference a defined alignment in the tree (RPS or Sequent Alignment) that is used prior to the full GD&T evaluation.
Force Surface Feature. Provides a radio button which forces the selected feature to be interpreted as a general surface.
Datum designations for a check are established in this section, which consists of two parts: a summary section and the individual datum selections.
The summary section defines how many datums are referenced as primary, secondary and tertiary and outlines the construction of the lower tier with the user of check boxes.
The following details section allows you to edit each datum designation and call out any Material Modifiers used with those Datums.
Zone. Applicable tolerance zone. See “Feature Check Specifics” for more information on Zone options.
Tolerance. Tolerance value for the feature check.
Material Modifiers. Defines the material modifier for the feature check’s selected datum. Choose from Maximum Material Condition, Least Material Condition or regardless of Feature Size.
Has Projected Zone. If checked, the projected zone will be used.
Projected Zone Value. Value used when projected zone is being used.
Tolerance Lower Tier. Tolerance used in Lower Tier evaluation.
Outer Tolerance Lower Tier. This designates the amount of the tolerance outside the surface of the part for the lower tier check. It allows for asymmetrical tolerance zones to be set. For symmetric tolerances this value should be set to one-half the total tolerance. Starting in the 2016.09.01 version Unilateral annotations are displayed graphically.
Material Modifier Lower Tier. Optional material modifier designation for the lower tier tolerance.
Tolerance Type. Dimension offer a tolerance type designation.
