This task shows how to create
offset revolute joints or centered revolute joints. Prior to performing
this scenario, you should be familiar with
revolute joint creation in beginner's mode |
|
Open the
Create_Revolute.CATProduct
document. |
|
Automatic switch to Design mode:
If you work with the cache system in visualization mode, you no longer
need to use Edit > Representations >Design Mode beforehand as
the switch to design mode is automatic (an eye appears as you point the
product in the geometry or specification tree). All you need to do is click
on the object.
|
|
-
Click Revolute Joint
in the Kinematics joints toolbar or select Insert > New
Joint > Revolute from the Menu bar. The Joint Creation:
Revolute dialog box appears.
-
Click New Mechanism. The Mechanism Creation
dialog box is displayed:
In our example, keep the default name Mechanism.1.
|
The Mechanism is identified in the specification tree |
|
-
Select the lines in the geometry area:
-
Line 1 = hinge axis
-
Line 2 = wheel axis
|
-
Select the planes in the geometry area:
-
Select the Offset option button.
Select the offset value for this, three methods are available:
In our example keep the default value. |
|
If you perform a right-click in the offset value
field, a contextual menu lets you select between two items: measure
or change step
Select the measure item: the Measure Between dialog box
and Measure Tools toolbar appear |
|
Select two entities. Keep this measure as offset
value. A warning message lets you copy the measure you defined. |
|
You can also change the step using Change step >
new one |
|
For more information, see Specifying a Parameter
Value as a Measure in the Knowledge Advisor User's Guide
and Measuring Minimum Distances & Angles between Geometrical
Entities and Points in the Space Analysis User's Guide
|
-
Assign the Angle driven command if needed.
-
Click Ok to end the Revolute Joint creation.
|
The specification tree is updated. |
