These tasks explain how to analyze sketched geometry, and
how to diagnose geometry. You will be provided either a global or
individual status and will be allowed to correct any problem stated in the
status. |
Open the
Sketch_Analysis.CATPart document. |
-
Select Tools > Sketch Analysis from the menu
bar.
Or alternatively, click Sketch Analysis
in the Tools toolbar (2D Analysis Tools
sub-toolbar).
The Sketch Analysis dialog box appears. It
contains three tabs: Geometry, Projections /
Intersections and Diagnostic.
Note that on the sketch, some geometrical items and constraints are
highlighted so that you can see them easily.
The Geometry tab displays information helping you know whether
the sketch geometry is valid.
- General Status: analyzes several elements globally.
Note that "Implicit Profile" refers to all profiles except for
profiles created via Output Feature
and Profile Feature
.
For more information, see Creating Output
Features and Creating Profile
Features.
- Detailed Information: provides a detailed
status/comment on each geometrical element of the sketch.
- Corrective Actions
: according to the
analyzed element you select and which is not correct, you will be
able to:
- turn this element into a construction element,
- close a profile that is not,
- erase a disturbing element,
- hide all constraints on the sketch,
- hide all construction geometries on the sketch and in the
detailed information area of the Geometry tab.

-
In the Detailed Information table, select
Point.11.
-
Click the Set in Construction mode icon to
turn the standard mode point into a construction mode point and solve the
problem.

Diagnosing Geometry
-
Click the Diagnostic tab.
The information on this tab displays a full diagnosis of
a sketch geometry. It provides a global analysis of the sketch as a
whole, and specifies whether individual geometrical elements in the
sketch are under-constrained (under-defined), over-constrained
(over-defined) or iso-constrained (well defined):
- Solving Status: provides a quick overall analysis of
the sketch geometry.
- Detailed Information: provides a detailed
status on each constraint and geometrical element of the sketch,
and lets you know what type of element it is (geometry,
constraint).
- Action :
according to the analyzed element you select, you will be able to:
- hide all constraints on the sketch and in the detailed
information area,
- hide all construction geometries on the sketch and in the
detailed information area of the Diagnostic tab.
- erase geometry
If you select items from the Detailed Information
table, they will be highlighted on the sketch, which enables you to
identify them easily. To solve constraint-based problems in the
sketch, you need to edit the sketch directly. |
|
-
Close the Sketch Analysis dialog box.
-
Right-click the Point.3 item in the sketch or from the
specification tree, and select Point.3 object > Fix.
-
Repeat this operation for the Line.1, Circle.1, Line.2
and Point.8 items.
-
Re-open the Sketch Analysis dialog box and
click the Diagnostic tab.
You can notice that the items you fixed are now iso-constrained.
