Why create Polylines ?

You can use this tool to create rapidly a polyline :

V5R8

Not using the point-point chain mode tool :

Using the line point-point chain mode tool :

Creating the lines point-point :

n-1 operationsInput data : 4 points

Input data : 4 pointsCreating the polyline:

1 operation

Whatever the number of point you want to

use, only one operation is necessary to create

the polyline.



Lets see now how to create a Polyline ...

How to create a PolylineV5R8



Click OK to create the Polyline.

2 Select already existing points

You can now create a Polyline in one operation.

Creating a Spline Curve

You can now use a curve to specify a tangency condition at a point of the spline

Create the spline selecting

existing points.

1

2

Select the point on which you want to add

a tangency condition and expand the

Parameters panel.

3

In the constraint type field, choose the new option

From curve that allows you to choose a curve to

add the tangency constraint.

Now you can select a curve to specify the

tangency constraint :

V5R8

4

Note : the point of the

spline must lie on the

selected curve.

2Select the first curve to

connect and a point on

this curve.

Creating a Connect Curve

4 If needed click on the

red arrow located oneither point to

reverse the

orientation of the

associated curve, or

use the dialog boxs

new option.

3 Select the second curveto connect and a point on

this curve.

Creating a connect curve, you have now the possibility to invert the

orientation of the associated curve from the dialog box

2 Select the two curves.

Intersecting Elements : Type of created Elements (1/2)

3 Choose the type of

element you want togenerate.

You can choose the type of elements that is created when you perform an

intersection operation :

V5R8

The type of element that was selected

is created (in our exemple, it is a curve

that is created).


15/26


Intersecting Elements : Type of created Elements (1/2)

Four different type of element can be generated :V5R8

- Points : when

intersecting two curves

or a curve and a surface. - Curves : when intersecting

two curves or a curve and a

surface.

- Faces : when intersecting a surface

with another or a surface with a pad.

- Contours : when intersecting a

surface with another or a surface

with a pad.

Creating an Offset Surface

In this lesson you learn how to create som e types of Surface Elements :

Creating an Offset Surface

2 Select the reference surface and key inthe offset value.

Click OK to confirm the offset creation.

If you want to create both side of the

offset surface, choose the Check both

side option.

4

You can now create both side of an offset surface with the same offset distance.

What is an Axis-to-Axis transformation ?

An Axis-to-Axis transformation transform geometry positioned according to an axis

system into another axis system :

Healing Surfaces : distance objective


25/26


Healing two surfaces, you have now the possibility to allow a remaining gap

between the surfaces.

Healing Surfaces : distance objective

Select the

surfaces to heal :12

If you should decide to allow a remaining gap between

the surfaces, key in the maximum tolerated value of

this gap.

Then CATIA inform you about the value of the

remaining gap :

3

4

0.2 mm gap

Key in a merging distance superior to the gap value.

V5R8

Joining Surfaces : Angle Tolerance


26/26


Joining Surfaces : Angle Tolerance

While joining surfaces, you can specify an angle tolerance.

If the angle value on the edge between two elements is greater than the Angle

Tolerance value, the elements are not joined

Select the elements to bejoined. The tangency

discontinuity between these

surfaces is 6deg :

1 2

V5R8

3

Click OK to

confirm the join

creation.

4

Activate the newoption Angle

Tolerance.

CATIA refuses to create the join

surface because the tangency

discontinuity between the

surfaces is greater than the

specified angle tolerance:
