You can quickly define constraints for sketch elements. To do so, you
have two possibilities. This task shows you how to:
Using the Sketch Tools Toolbar
The Geometrical Constraint and Dimensional Constraints
options are activated by default:
- Geometrical Constraint
displays all detected geometrical constraints. This option is only
applicable when creating an object. Creating geometric constraint is
possible independently of this option.
- Dimensional Constraint
only displays distance constraints when the option is activated.
|
|
Create a rectangle with a corner.
Geometrical Constraints
|
|
-
Keep only Geometrical Constraint
activated.
-
Click Circle
from the Profile toolbar.
-
Select the corner center to define the one of the circle.
-
Drag the cursor to define the circle dimensions.
-
Click in the geometry when you are satisfied with the
dimensions.
|
|
The circle is created and the geometrical
constraints have been detected. These constraints can be visualized either
in the geometry area or in the specification tree. |
|
|
Optionally, select the circle and move it to see
the tangency constraint is well applied.
-
Right-click the construction line and select Delete.
The construction line has been deleted as long as its associated
geometry.
|
|
Dimensional Constraints
-
Keep only Dimensional Constraint
activated.
-
Click Circle
in the Profiles toolbar.
-
Select the corner center to define the one of the circle.
Note that this symbol
is
displayed by the SmartPick as a coincidence between two points is
detected.
|
|
|
The Sketch tools toolbar expands. |
|
-
Enter a radius value, for instance 20mm.
-
Press Enter.
The dimensional constraint is displayed in the
geometry. |
|
|
If you want to keep the dimensional constraints
displayed, Dimensional Constraint
must be activated. |
|
Use the Constraints Toolbar
|
|
-
Keep your sketch open.
-
Select the rectangle top line.
-
Click Constraint
in the Constraints toolbar.
-
Click in the geometry to create the constraint.
|
|
-
Select the rectangle left hand side line.
-
Click Constraint
from the Constraints toolbar.
The geometry color is swapped to the purple color which means that it is
over constraint.
|
|
|
|
You can use the Sketch analysis to have a diagnosis the
over-constraint elements. This option will be seen later on in this
tutorial in the Analyzing Sketches section
which comes next. |
-
Click in the geometry to create the constraint.
-
Right-click the Radius constraint and select
Delete.
The constraint is deleted and the geometry is no longer over-constrained.
|
|
|
- You can also set constraints using Constraints Defined in Dialog
Box
available in the Constraint toolbar. You just need to select the
constraints you wish to apply.
- You can refer to Selecting Using a Filter and
Selecting Using Other Selection... Command in the
Infrastructure User's Guide to help you select the elements that
you want to constrain.
