How do you fix a part in CATIA Assembly?
Fixing a Component
- Click the Fix component icon: Fix in Space.
- Select the component to be fixed, that is the light blue component. The constraint is created.
- Move the fixed component using the compass.
- Update the assembly to see which component is moved: the fixed component returns to its previous location:
How many types of assemblies are used in CATIA?
two types
In CATIA you can create assembly models by adopting two types of approaches. The first design approach is the bottom-up approach, and the second one is the top-down approach. Both these design approaches are discussed below. The bottom-up assembly is the most preferred approach for creating assembly models.
How do you fix components?

There are two ways of fixing a component: by fixing its position according to the geometrical origin of the assembly, which means setting an absolute position. This operation is referred to as “Fix in space”. by fixing its position according to other components, which means setting a relative position.
Which constraints are used in assembly?
Constraints in Assembly Design
- The Fix Constraint.
- The Offset Constraint.
- The Coincidence Constraint.
- The Angle Constraint.
- The Contact Constraint.
How many types of assembly constraints are available in CATIA?
There are four basic assembly constraints, each with unique solutions and options. Used to define a tangential relationship between two parts. The tangent constraint is generally applied to circular faces and planar faces.

How do you Unfix parts in an assembly?
To unfix a component(s), right click on them and select “Float”. Moving a component within fully constrained assembly will move the entire assembly.
How do you make an assembly Float?
To fix or float an assembly component:
- Right-click the component in the graphics area or the component’s name in the FeatureManager design tree.
- Select Fix or Float.
- In assemblies with multiple configurations, select This Configuration, All Configurations, or Specified Configurations.

How do I rotate part of an assembly?
On the ribbon, click Assemble tab Position panel Free Rotate . Click the component to rotate. Drag to the appropriate view of the component. To rotate in any direction, click inside the 3D rotate symbol and drag in the appropriate direction.
How do you rotate a component in an assembly?
Click Rotate Component (Assembly toolbar) or Tools > Component > Rotate. The Rotate Component PropertyManager appears, and the pointer changes to . Select one or more components in the graphics area. Select a component and drag in any direction.
