Compass

The compass is used to manipulate the orientation of parts, assemblies, or sketches. You can also orient the view of the parts and assemblies.

Fig. 14: The compass

Constraints Constraints are the logical operations that are performed on the selected element to define its size and location with respect to the other elements or reference geometries. 1. Geometric constraints, and 2. Assembly constraints

Geometric Constraints

Performed in the Sketcher workbench to define the size and position of a sketched element with respect to the other elements. 1. Distance: is used to apply a distance dimension between any two selected entities. 2. Length: is used to apply a linear dimension to the selected line. 3. Angle: is used to apply an angular dimension between any two selected lines. 4. Radius / Diameter: is used to apply a radius or a diameter to the selected circular entity. 5. Semimajor axis: is used to apply a dimension to the major axis of the selected ellipse. 6. Semiminor axis: is used to apply a dimension to the minor axis of the selected ellipse. 7. Symmetry: is used to force the selected sketched entities symmetrical about an axis. A line

segment can be used as an axis. 8. Midpoint: is used to force a selected point to be placed on the midpoint of the selected line. 9. Equidistant point: is used to force a selected point to be placed at an equal distance from any

two preselected points.

8

10. Fix: is used to fix a selected entity in terms of its position with respect to the coordinate system of the current sketch.

11. Coincidence: is used to make two points, two lines, a point and a line, or a point and a curve, coincident.

12. Concentricity: is used to make two circles, arc, an arc and a circle, a point and a circle, or a point and an arc, concentric.

13. Tangency: is used to force the selected line segment or curve to become tangent to another curve.

14. Parallelism: is used to force any two selected line segments to become parallel to each other. The selected line segments can also be axes.

15. Perpendicular: is used to force any two selected line segments to become perpendicular to each other. The selected line segments can also be axes.

16. Horizontal: forces the selected line segment to become horizontal. 17. Vertical: forces the selected line segment to become vertical.

Assembly Constraints

Performed in the Assembly design workbench to restrict the degree of freedom of the component and to define its precise location and position with respect to the other components of the assembly. 1. Coincidence: is used to force two selected entities to coincide with each other. 2. Contact: is used to force two selected faces to create a contact between each other. 3. Offset: is used to place two different selected faces, planes, or central axes at a distance with

respect to each other. 4. Angle: is used to place two selected entities at an angle with respect to each other. 5. Fix: fixes the position of the selected part in the 3D space. 6. Fix Together: fixes the position of the two different selected parts with respect to each other. 7. Quick: is used to apply the most appropriate constraint to the elements in the current selection

set. Sketch Constraints 1. Correct set of constraints are required for all engineering objects which is enforced in CATIA

through the use of constraints. 2. Two forms of constraints are available: Quick and through Dialogue box. 3. There are some sketcher auto-constraints-origin, horizontal, vertical etc which do not appear in

the tree. 4. Non-auto constraints can be deleted from the tree. 5. A fully constrained sketch is green, under-constrained is white and over-constrained is purple.

Geometrical Set The geometrical set is defined as a body that includes the newly created planes, surfaces, wireframe

elements, and reference elements.

Feature A feature is defined as a basic building block of a solid model. The combination of various features

results in a complete model. In the Part Design workbench, the features are of the following four types:

1. Sketch-based features. 2. Dress-up features. 3. Transformation features. 4. Surface-based features.

Note 1. If you are trying to undo, and it shows undo empty selection, select the curve and then you can

undo till you are happy. 2. Use ‘Exit this workbench’, icon on the right side of the toolbar an arrow pointing up.

TUTORIAL 1A: CREATING POSITIVE FEATURES

Part Design (** Close the Assembly design workbench that is opened by default when starting CATIA before

opening Part design workbench**)

1. Menu bar: Start/Mechanical Design/Part Design 2. Uncheck ‘Hybrid design’ and Check ‘Create a geometrical set’. 3. Invoke the Sketcher (Paper and Pen Logo on the Right Toolbar) and select a Plane. You can

select the plane and invoke the sketcher or vice versa. Initially, you can only sketch on the 3 Cartesian Planes, but once a Part is created, you can sketch on any of its planes or create auxiliary planes.

4. Prompts will appear in the lower region of the window as you move the mouse, i.e. in the Status bar.

5. Select/Tool or Tool/Select sequence is up to you but if you need to select multiple parts, select has to come first.

6. Infinite UNDO is possible, but tools must be switched off first. 7. If you modify a sketch, double click on it in the tree and do not start a new sketch. 8. Draw the sketch of the model using the Profile, Line, Arc, and Circle tools. 9. Use of the Pad Tool to create 3D parts. Take Pad thickness of 30mm.

TUTORIAL 2A: CREATING NEGATIVE FEATURES

Part modification tools and their use 1. Pocket: Negative Pad: It’s a tool to remove material from an existing object by extruding the

sketch to a given depth condition. Take note that you can use the sketch in pocket to remove material in either direction.

2. Hole: Special Pocket: You can select any region in the object and invoke the Hole tool. It will ask for the diameter and has special features. Take note the Extension can be used to select the depth or surface while the type offers taper, countersunk, etc and details of thread if needed.

3. Groove: Negative Shaft: It is a tool for removing material from an object that requires an axis and a profile. It removes the material from the object by sweeping the profile about the axis.

4. Slot: Negative Rib: Take note for rib, it is not necessary to have the centre curve and the profile attached. For a slot you need a solid object, a profile and a centre curve.

5. Shell: Hollowed out solid: Indicate the wall thickness and the faces to remove.

14

TUTORIAL 2B: DRESS UP TOOLS

Dress up tools and their use 1. Fillet: It is meant to round the edges or surfaces. 2. Chamfer: Meant to modify the edges with a plane. 3. Threads: Use the ‘Hole’ tool to create these. Select appropriate type. Metric Thick pitch (M1,

M10 etc) and notice that the pitch and hole diameter is automatically created. You will need to click on the hole to find the details of the thread as the details of the thread will not appear in the tree.

4. Pattern: Creating multiple copies such as holes/slots or any need for multiple instances within an object.

15

TUTORIAL 2C: CREATING PLANES AND HOLLOW TUBE

The below sketch is for a Plumbers tube which is hollow and has a 45 degree joint. Use 100 mm as the outer diameter for all the pipes and, the length and the thickness of the pipes are for you to choose any value you want. The object should look similar to the one below.
