This task shows you
how to create a tolerancing capture, create and associate a camera to the
capture and preview the capture in 3D.
For a better visualization of the
captures a 3D representation of the capture and/or a hidden text can be
defined at the capture definition. |
 |
The purpose of
capture features is to provide in 3D the views/sheets of 2D drawings
flexibility for annotation display organization. It allows you to organize
the display of 3D annotations the way you want.
You can, for instance, create capture for:
- Functional part area.
- Specifications answering to given functional requirements.
- 2D view equivalent.
- 2D sheet equivalent.
- etc.
|
 |
Open the
Annotations_Part_05.CATPart document. |
 |
-
Click Capture
in the Capture
toolbar.
The Capture Definition dialog box appears. |
 |
-
Click the More>> button.
The Capture Definition dialog box is expanded. |
 |
The Capture Definition dialog box displays the
following information:
- The capture feature name.
- Display in 3D: displays the capture in the geometry window.
- Hidden Text: displays a text as tooltip when
passing over the capture feature in the specification tree or
geometry window.
You can leave the field blank.
- Append External File Content: imports from a text file the
hidden text content.
- Reset Field: empties the hidden text content.
|
-
Select the Display in 3D option.
-
Type in the Hidden Text field the
following text: This is the capture hidden text
-
Click OK in the Capture Definition dialog box.
|
- The Capture.6
is created and displayed in the specification tree and geometry window.
The name of the capture and a rectangle framing the
middle characters of this name appear in the graphic area, and they form the
capture callout. When you rotate the part, the capture callout remains
parallel to the screen.
- The hidden text is displayed when passing over the capture
feature.
|
 |
 |
- The text of a capture callout is not editable, but follows the
modifications of the capture name.
- The capture properties enable you to customize the display of the
capture callout.
- The Position And Orientation toolbar
applies to capture callouts:
- for capture callouts with an associated camera:
- The X,Y manipulation applies to the text of the callout,
- The Z manipulation applies to the text and the pyramid of the
capture callout.
- for capture callouts with no associated camera:
- The X,Y manipulation applies to the text and the frame of the
callout,
- The Z manipulation is not relevant.
- The capture callout is not linked to any annotation plane.
- The capture callout orientation is fully controlled by the 3D point
of view attached to the capture.
- If you change a camera associated to a capture callout, the previous
capture callout is deleted and a new one is created.
- If you remove a camera associated to a capture, the capture callout
remains unchanged, the information No camera is displayed in the
camera list.
|
-
Move and rotate the part like this.
-
Click Named Views
 |
Create a camera is also available for any workbenches from the View
> Named Views... menu. |
-
Click Add in the Named Views
dialog box which appears.
 |
- The Camera 1 is created.
- The part location and zoom are recorded in the camera
properties.
Click the Properties button in the Named
Views dialog box to edit these properties.
- As the 3D shape orientation and zoom are recorded in the
capture properties, this information is kept even when the
associated camera is deleted. In this case, UndefCam
is displayed in the combo list of the Capture Options
toolbar.
|
-
Select Camera 1 in the combo list of
the Capture Options toolbar.
 |
 |
- Camera 1 is now associated with
Capture.6.
- The flat rectangle framing the name of the capture is
replaced by a rectangular-based pyramid that represents the 3D view point,
see:
-
When the capture is activated, the apex is displayed at
the center of the screen and the base of the pyramid is parallel to the
screen
-
The name of the capture can be moved and a leader can be
added.
|
-
Click Exit from capture
.
|
 |
To edit a capture, double-click the capture in the
specification tree, or the geometry window when it is displayed. |
 |
We enter the Tolerancing Capture workshop, for editing the
capture. When exiting Capture Edition, all the modifications
(Show/NoShow status of the annotations, active view, camera,
clipping plane, etc.) are kept i.e. visual status of the CATPart
is the same as capture edition.
To get back to the previous state, user should create a specific
capture before and recall it just after exiting the capture
workshop. |
|
|
|
3D Preview of capture
|
|
When a capture is
selected in 3D or in the feature tree, the clipping and section profile
of the active view in the capture are displayed.
 |
The clipping plane and section profile of the
active view inside a capture are displayed only if the 3D-Annotation-Query Switch On/Switch Off
in the Visualization toolbar is active. |
You can see that
the section profile is displayed as thick orange line and the clipped
surface is seen as the green section.
 |
-
The clipping
plane, which is visualized, helps in better visualization
when the active view in a capture is clipped.
-
Section
profile is displayed as thick line. The section profile is
shown only when the active view of the selected capture is a
section cut or a section view. For other views only the clipping
will be seen not the profile.
-
The clipped
part, which is seen, is similar to when the
Clipping Plane
option is activated. The properties for the representation of
the clipping plane is taken from Tools > Options >
Mechanical Design > Functional Tolerancing & Annotation, Display
tab, Hatching, coloring or dotting for clipping plane
area, Display option
set for the clipping plane.
-
The status of
Clipping Plane command does not impact the capture selection
process. Even if the command is deactivated the clipping profile
is seen and the view is clipped on capture selection.
-
If
Clipping Plane command is activated, the clipping of the
active view is displayed. If a capture is selected whose active
view is different from the active view
in the CATPart, then the clipping of the active view is replaced by the
clipping of the active view in the capture. The clipping of the active view
will be restored when no capture is selected.
-
If more than
one capture is selected, then the last selected capture is
taken into account and the profile and clipping plane of its
active view is displayed.
-
The
Show/No Show
status of the capture does not change the behavior. Even if the
capture is in
No Show
mode, the clipping plane and the section profile are still
displayed.
