The compass is a powerful tool to move and
manipulate objects, especially in the Assembly
Design, Freestyle, and Digital Mockup
products
Base of the compass(or privileged plane)Default is XY plane
The default orientation of the compass
is parallel to the reference XYZ axis
system
The default location of the compass is
the top right corner of the screen
When to use it ?
To Pan, Rotate Geometry in 3D
To deform surfaces like patches and define cutting
plane in Freestyle
To move components in an assembly and in Digital
Mockup To move and rotate elements in the Sketcher, parallel
to the sketch plane

What is a Sketch ?
To begin a new part, a 2D profile is needed.
The 2D profile can be parametrized by
constraints.
The Sketcher is a 2D dimension workspace:the elements created within the Sketcher are
exclusively 2D WIREFRAME elements.
Back to the 3D space, the elements createdin the Sketcher are seen as a single entity:the SKETCH.
This Sketch can be the base profile of mostof the Part features.

The Sketch Support
The sketch support MUST be PLANAR.
You can create a Sketch either on a plane or on a planar face of an existing geometry:
Sketching on a Plane:-Any plane can be the support of a Sketch-If needed, you can create planes dedicated tosketches
-The Sketch Origin is the Plane Origin
Sketching on the Face of an Existing Feature:-The face of the feature must be planar
-The Sketch is linked to the Feature on which it is created
Note: It is better to create the sketch on a
stable support.

Tips for working in the Sketcher (1/2)
While working in the Sketcher Workbench, here are a few things to consider:
The Screen Orientation:- As a general rule, it is recommended that the screen be oriented parallel to the sketching plane you arein. This will happen automatically provided the options panel is set as shown.
The Normal View ICON:- While in the Sketcher, you may sometimes inadvertently rotate the part, causing the screen to be nolonger parallel to the sketching plane. If this occurs, you select the Normal View ICON, and the screenwill again be positioned parallel to the sketching plane.
When you exit the Sketcher, the screen will immediately return to the previous orientation.

Tips for working in the Sketcher (2/2)
Sketching in 3D:- Even though you will be creating 2D sketchedgeometry, all geometry in 3D space is accessible.This will mean it will be possible to constrain the2D geometry to features not in the same sketchingplane. You can rotate the part, use any geometry,then select the Normal View ICON to return thedisplay to being parallel to the sketching plane.
The Normal View ICON, continued:- In addition, if you desire to invert the orientation (look at the sketching plane from the other side), youcan select the Normal View ICON an additional time.

An Axis element must be includedin a Sketch from which a Shaft orGroove solid feature is created. TheProfile to be swept around this axismust either be Closed or have itsendpoints Coincident to the axis.
An Axis drawn into a Sketch canalso be used (but not required) to
generate a Surface of Revolution. Aseparate Line or Solid Edge canalso serve to specify the axis ofrevolution. Also, the Profile neednot be Closed nor Coincident to theaxis in this case.

When creating a sketched shape, there are many tools that can be used.
An often asked question is should you use the Profile tools or should you create individualelements and trim them to form the shape desired.

or lines only when needed tocomplete or modify a shape.
For example, if youwanted to createthis shape:

To create cornered or chamfered edges on features based on sketches, you
have two possibilities:-Create a complex sketch including the corners and chamfers:
-Create simple sketches and add the corners and chamfers afterward:
Considering these arguments, it is you to decide if the corners andchamfers have to be included in the sketch.
This kind of feature is updated faster, but complex
sketches are harder to edit and modify.
It takes more time to update this kind of feature, butcorners and chamfers can be easily reorder,deactivated or suppressed if necessary.

Since the 3D Spline Tool - available within the Wireframe&Surfaces (WFS) or Generative Shape Design(GSD) workbenches - can also be used in a 2D manner (with Geometry on Support being a plane),when should you use the Sketcher Spline and when is the 3D Spline more appropriate?
In general, use the Sketcher Spline to create
Sketches for generating solid Sketch-BasedFeatures. (Although Pads and Pockets can begenerated from 3D Splines)
Use the 3D Spline when you need morecontrol over the Spline - i.e. Tangent Tension,Curvature Direction, Curvature Radius.
Surfaces can be generated from Splinescreated by either method.

Here are some modeling techniques to consider when creating a design:
1. Do not locate sketches/features to the edges of fillets or chamfers. This establishes arelationship between the fillet or chamfer and the feature being created. If the fillet orchamfer changes size, the feature may move without warning. If the fillet or chamfer isdeleted, an error will result which requires additional rework.

here. A better alternative is to make sure theconstraint is made to a more stable feature (the faceof the part), not the edge.

Construction geometry are elements created in the sketch to assist in the development
of the required profile. Construction geometry will not appear outside the Sketcher norwill be used in the creation of any part feature.
Construction geometry is created anytime this ICON is highlighted (it is located in theSketch Tools toolbar). Construction geometry is created in the same manner as all other sketched
geometry. An example of the use of construction geometry is shown here:
In this example, the construction of asymmetrical shapes was aided by the
use of construction geometry.

Without Constraints, geometry can be moved freely just by using the mouse to drag them. If Sketcherprofiles are moved, so do the solids that are supported by them. In the context of an assembly, if onepart moves, another part that is related to it may also move.
Although in CATIA V5 geometry will remain in place when put there, without Constraints anysubsequent movement of elements by the user may go unnoticed and affect Form Fit and Function ofentire assemblies.
Hence, Constraints serve to mathematically fix geometry in space.
They also can specifically relate one element to another and serve as visual feedback to the user onwhat these relationships are.
After Constraints are created, they are easily modified by merely changing their values or placement.
From the ease at which Constraints may be modified and from the inherent downstream associativityof V5, the user can quickly explore alternative designs.

A Dimensional Constraint, one type of Geometric
Constraint, specifies the distance between two elements.
This distance can be specified as a lineardistance, an angular distance, or a radial distance depending
on the type of geometric elements involved

Sketching in context is using existing geometry to create new geometry
When sketching with CATIA V5 space geometry is visualized. You can use it
to guide your sketch
3D geometry used to
sketch and constrain profiles
At first, the sketch has to only be made
to conform to the spatial intent i.e. the left
or right of a hole, on the inside or outside
of a pocket, on the top or bottom of a pad,
etc.
Later, the exact dimensions or precise
geometric constraints (concentricity,
parallelism, coincidence...) can be applied
to the sketch (or profile) to define it
precisely

Relations between Dimensions:
Dependencies can be established between dimensions(For example, A=B+C/2)
Originally a part of the Knowledgeware set of products,this functionality has been incorporated into the V5infrastructure and is generally accessible from allWorkbenches.
In CATIA V5, in addition to relationships between
dimension values, dimensions can be made dependenton other parameters such as Forces, Temperature, Time,or Material Properties etc ...

Tips on initial sketch of geometry (1/2)

Initial Size of Sketch:- As you begin to create geometry for a sketch, try to create it reasonably close in shape and size to theeventual final constrained sketch. This is because a sketch that is greatly different in size from the finalshape, will become distorted when the actual dimensional constraints are applied, making it difficult to
understand what is occurring.
Observing the values in the Sketch Tools toolbar will help you tounderstand the real size of the elements being sketched.
As you can see, it is
hard to determine theinitial size visually, whenthere may be differentzoom factors applied.

Constraint Detection/Creation:These settings in the Sketcher Options page control whether geometric constraints are detectedduring the development of the initial sketch. You can control the types of things detected in the SmartPick panel. It is helpful to have most of these items always turned on.
This ICON controls whether geometric constraints are automatically created during the developmentof the initial sketch. When geometry is fairly simple, it may be advantageous to have this ICON selected,as this will help speed the finalization of the shape. However, with more complex geometry, having thisICON chosen can lead to confusion and the potential for the creation of unwanted constraints.
This check box performsthe same task asselecting the ICON.
Notes:

Tips on Constraint Creation
There are two tools to define the constraints on a sketch. Both can create bothgeometric and dimensional types of constraints. It is suggested that while learningconstraint creation you use the following:

Geometric Constraints Dimensional Constraints
However, as you become more skilled, it is more efficient to use the process below to
create all constraints:
Double-clickon this ICON
Selecting geometry createsdimensional constraints
Selecting geometry, then
right-clicking createsgeometric constraints
Notes:
CATIA V5 Fundamentals
Controlling the Constraint Dimension Direction
When creating a dimension constraint on a profile, the dimension direction isdetermined by the type of element selected. If the elements are points or circles, thedefault dimensions direction is parallel to the line between the points or circle centers
5/22/2018 Tutorial Catia V5
114/497

default dimensions direction is parallel to the line between the points or circle centers.
When creating a dimension constraint between two circles or points, you can force ahorizontal or vertical dimension orientation by right-clicking and choosing the desired
orientation.

The base feature is usually started from a2D profile, sketch, or surface element.
This lesson will focus on the parts wherethe base feature begins from a 2D profile
or sketch. Which in CATIA is referencedas Sketch Based Feature.
Notes:
CATIA V5 Fundamentals
Selecting a Base Feature
When selecting a base feature, it is recommended to select the basic elementswhich will convey the primary shape or function of the part. This does not meanthe level of detail for a base feature have to be completely defined. For example,some corner fillets, holes, pockets, etc might not be originally created as part ofthe base feature sketch but created later using another feature for its definition.
