This task shows you how to automatically
propagate geometry selection corresponding to the same surface. |
 |
The propagation of geometry selection is
possible 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.

-
Select the cylindrical hole as shown.
-
Click 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 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 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):
- With the same cylindrical canonicity.
- With the same diameter.
- That are parallel with the first selected cylinder.
- Whether the extremity edges of the selected
cylindrical face are contained or not in a plane:
- Extremity edges are not contained in a plane:
only the 3 first conditions are taken into account
(With the same cylindrical canonicity, the same
diameter and parallel with the first selected
cylinder).
- One extremity edge is contained in a plane: only
faces with edges coplanar with the extremity edge
plane are selected.
- Extremity edges are contained in planes:
- When the selected cylindrical face has
been selected in the geometry area: the
plane nearest of the selection point is
chosen and only faces with edges coplanar
with this plane are selected.
- When the selected cylindrical face
has been selected in the
Tree
(no selection point): two sets of faces with
edges coplanar with these planes are
defined: either the number of faces in the
two sets are the same, and the set related
to the first edge is selected, or the set
with the biggest number of faces is
selected.
- Select
all same apex angle cones - propagates the
selection to the cones in the 3D part with the same apex angle.
- Select
all same small diameter, high diameter parallel Tori -
propagates selection to the tori in the 3D part with the same
diameter.
- All same User
defined features
-
This option selects all the user features or technological
result of user feature of same type in the part (at part level)
or in the part instance (at product level)
- All same
diameter, same pitch, parallel CG thread Cylinders
-
This option selects all the Constructed Geometry thread
cylinders in the 3D part with the same diameter and pitch, and
axis parallel with the selected Constructed Geometry Thread
cylinder.
- 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 Position Specification
in the dialog box.
The Geometric Tolerance 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 (Text
sub-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 commonly created for all the faces. |
 |
|
|
|
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 (Flag
Note
sub-toolbar).
The Flag Note Definition dialog box appears. |
 |
The
Tools Palette
for geometry propagation is also displayed.
 |
There is only one 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. |
