How do I use constraints in Catia Assembly?

How do I use constraints in Catia Assembly?

Select the Constraints of Given Components: Select the components, right-click and select xxx object -> Component Constraints contextual command. Editing Constraints: you can cut and paste , copy and paste and even delete constraints. Update an Assembly: constraints displayed in black indicate they need an update.

How do I use constraints in Catia V5?

Geometrical Constraints

1. Keep only Geometrical Constraint activated.
2. Click Circle from the Profile toolbar.
3. Select the corner center to define the one of the circle.
4. Drag the cursor to define the circle dimensions.
5. Click in the geometry when you are satisfied with the dimensions.

What are some assembly constraints?

Assembly Constraints

• Mate two planes.
• Specify that cylindrical features on two parts remain concentric.
• Constrain a spherical face on one component to remain tangent to a planar face on another component.

How do I assemble components in Catia V5?

1. Click Component > Assemble > Assemble with an assembly open.
2. Select CATIA V5 CATPart (*.
3. Select the part file you want to assemble in the existing assembly as a part component or browse to find the file.
4. Select Import to import the CATIA V5 part and assemble it as an imported component in the existing assembly.

What is dimensional constraint in Catia?

To create a precise 2D sketch in CATIA, we use constraints. What does “constraint” actually means? It means that we are restricting the degree of freedom of the sketch. Consider, you want to constraint a line. If you provide its length, then it ensures that the length of the line is under control.

What are constraints between parts in an assembly called?

iMates are constraint pairs in parts that define how a part fits together with other components each time it is placed in an assembly.

How do I see constraints in Catia Assembly?

Select Analyze -> Constraints . The Constraint Analysis dialog box is displayed. The Constraints tab displays the status of the constraints of the selected component: Active Component displays the name of the active component.

What are the constraints in Catia?

Geometrical constraints include Parallelism, Symmetry, Coincidence, Tangency, Midpoint, Perpendicular, Concentricity, etc. Geometrical constraints are usually given automatically by the software, but at some place we may need to give a particular constraint.

How many types of assembly constraints are there?

First, click the Constrain command and a window will pop up. There are 4 tabs: Assembly, Motion, Transitional, and Constraint Set. The one we will use first is the Assembly. There are 5 different types of constrains in the Assembly tab: Mate, Angle, Tangent, Insert, and Symmetry.

How do I import assembly into Catia?

1. Click File > Open.
2. Select CATIA V5 CATPart (*.
3. Select the CATIA V5 *.
4. Select Import in the File Open dialog box.
5. Select Part or Assembly as Type.
6. Continue to use the current profile that is in use or select an import profile from the Profile list.

How may types of assemblies are used in Catia?

There are basically three types of documents that are used in Assembly Design: the overall assembly, sub-assemblies, and individual part models. CATIA uses the word ‘product’ to refer to an assembly, and ‘part’ to refer to an individual model.

How to create an assembly in CATIA V5?

To make public a feature like a point, axis system or line, you must navigate on Tools -> Publication and select all features that you want to make public. Now, I will show you step by step how to create an assembly in CATIA V5. Using the menu go to File -> New -> Product and click OK.

What are the steps in a CATIA tutorial?

In this tutorial you will: 1. Model the four CATIA parts required. 2. Create an assembly (CATIA Product) containing the parts. 3. Constrain the assembly in such a way that only one degree of freedom is unconstrained. This remaining degree of freedom can be thought of as rotation of the crank.

How is part design environment used in Catia?

Part design environment is used to create 3D models from the basic 2D sketches created in sketcher environment. In most CAD software, the equivalent of this is called EXTRUDE, but in CATIA we call it PAD. This command adds material in the third direction, a direction other than the sketch. The POCKET commands somehow the opposite of PAD command.

What is a coincidence constraint in CATIA V5?

Coincidence Constraint – this command create a coincidence constraint between two components of the active component; Contact constrain – creates a contact constraint between two components of the active component; Offset Constraint – creates an offset constraint between two components of the active component;
