This task shows you how to automatically
propagate geometry selection corresponding to the same surface. |
|
The propagation of geometry selection for all
the faces that define:
- The same sphere surface.
- The same plane surface.
- The same cylinder surface.
- The same cone surface.
- The same torus surface.
- A pattern of parallel cylinders.
- A pattern of spheres.
|
|
Open the
Common_Tolerancing_Annotations_04.CATPart document.
|
|
-
Select the cylindrical hole as shown.
-
Click the Tolerancing Advisor
in
Annotations toolbar.
The Semantic Tolerancing Advisor dialog box appears. The
geometry propagation selection commands are available.
|
The options are activated according to the type of face
selected depending on the canonicity. |
In this case as the cylindrical face is
selected we have two options out of the three available options
activated:
- All same canonicity faces - This option
selects all the faces of the part (at part level) or of the part
instance (at product level or at process level – the part
instance being the one that corresponds to the last selected
face) that have the same canonicity.
- All same diameter parallel sphere - This option
selects selects all the faces of the part (at part level) or of
the part instance (at product level or at process level – the
part instance being the one that corresponds to the last
selected face) that have spherical canonicity and the same
diameter.
- All same diameter parallel cylinder - This option
selects selects all the faces of the part (at part level) or of
the part instance (at product level or at process level – the
part instance being the one that corresponds to the last
selected face) that have cylindrical canonicity, the same
diameter and parallel to cylindrical face selected.
- You can also select additional faces if required.
|
-
Select the All same
diameter parallel cylinder
option. You can see that all the cylindrical
surfaces are highlighted.
-
Click the Position Specification icon:
.
The Geometric Specification dialog box appears. Click OK.
The specification is created.
Click Close
in the Semantic Tolerancing Advisor
dialog box to end the command.
-
Select the spherical hole.
- Click
Text with Leader
in the
Annotations
toolbar.
The Text Editor dialog box appears. |
|
- The
Tools Palette
for geometry propagation is also displayed.
|
There are two options in the Tools Palette:
- All same canonicity faces
- All same diameter parallel sphere
- You can also select additional faces if required.
|
|
|
The Tools Palette is displayed according to the type of
face selected depending on the canonicity. |
-
In this case, select the All same diameter parallel
sphere option. You can see that all the spherical surfaces are
highlighted.
-
Enter the text, for example "All Spherical Faces" in the
dialog box.
Click OK to end the text creation. You can
click anywhere in the geometry area too.
The text is created for all the faces commonly. |
|
|
|
|
Using the All same canonicity faces option
|
|
Open the
Common_Tolerancing_Annotations_05.CATPart document.
|
|
- Select the planar
surface as shown.
- Click
Flag Note with Leader in
Annotations
toolbar.
The Flag Note Definition dialog box appears. |
|
- The
Tools Palette
for geometry propagation is also displayed.
|
There is option in the Tools Palette:
- All same canonicity faces
- You can also select additional faces if required.
|
-
Select the All same canonicity faces option. You can see that all the
planar surfaces are
highlighted.
-
Enter the flag note's name as Geometry Propagation in
the Name field.
Click OK.
The flag note is created for all the faces commonly. |
|
