1 - Export of the Catia tree structure in .txt file

Saving the Catia structure in .txt format:

is really fast and easy

enables you to export the tree structure in a .txt file

enables you to copy easily the ST references from

this file instead of opening successive Properties

tabs

is convenient for preliminary design phase while

the Excel BOM is not yet available

Tree structure too long for a screenshot ???

Think .txt export !

2 - Graphic Properties Wizard – a clever tool !

The “Graphic Properties Wizard” tool enables you to check the graphical

properties of a selected element and the level on which this property has been

defined.

You can find this tool in the “Graphic Properties” toolbar:

The “Graphic Properties Wizard” tool available checks are:

1 - Color properties

2 - Opacity properties

3 - Linetype properties

4 - Thickness properties

5 - Symbol properties

6 - Show properties

7 - Pick properties

8 - Layer properties

9 - Low Intensity properties

2 - Graphic Properties Wizard – a clever tool !

How does it work ?

1 - Select the element on which you want to check the properties (it can be either

a solid or a wireframe element)

2 - Launch the Graphic Properties Wizard tool

3 – Select the graphic property type you want to check (cf previous slide)

Want to know more about this tool ?

Visit the dedicated Catia online help pages:

Graphic Properties Wizard: Catia online help page Link

Graphic Properties: Catia online help page Link

Using the Graphic Properties toolbar: Catia online help page Link

Additional tip:

If you are lost and you do not manage to change the graphical

properties as you would like to, it is possible to reset the

graphical properties as follow:

Select the Body to be reset Right mouse click to access the

contextual menu PartBody object Reset Properties

Important note: Don’t forget to readjust the line thickness

after this action!

3 - Measurement of 3D curves

8

Graphical selection measurement:

1st Vertex

2nd VertexThe measure is only

applied to the selected

curve portion and is

delimited by 2 vertex

Tree function selection measurement:

Function selected in the tree

The measure is applied

to the complete selected

operation

!Do not keep measures in the tree !!!

It may be impossible to update

assemblies then…

3 - Measurement of 3D curves

9

Curve measurement using a Formula:

1 - First of all, we need to create a new length type formula

34th Catia/SmarTeam Users’ Forum05/12/2019EDMS 2279229

3 - Measurement of 3D curves

10

2 - Double click on the formula in the “Parameters” node

4 - Right click on the

“value” field and select

“Edit Formula…”3 - Rename

the formula

(optional)

5 - Select the “Measures” dictionary

then “length (Curve, …): Length”

3 - Measurement of 3D curves

11

6 - Double click on the curve you want to measure in the Catia tree

7 - Validate this warning message

8 - Final result:

An easily accessible

and readable

parameter which will

be automatically

updated while

modifying your

geometry

Curve length parameters can also be used as reference on the Drawing:

1 - Create a text box + right click on text to be replaced with driven value:

4 - How to build a parametric curve

Different approaches:

• 2D curve create a law with a parametric equation

• 3D curve create a 3D curve with a Cartesian parametrization

How to build a 2D curve:

• Create a law (equation of the curve)

• Create a guide (a line OR a planar curve)

• Define a support (a plane)

13

y = a × sin(x × b × 360deg)

4 - How to build a parametric curve

Result:

Inputs:

• Line.1 is the initial guide line

• Law has been applied on the Parallel.1 curve

• Plane XY is the support

• Parameter “a” is the amplitude of the sinusoid

• Parameter “b” is the wave number

• Parameter “Angle” defines the period to be applied to the law

4 - How to build a parametric curve

How to build a 3D curve:

• Create a “Curve from Equations”

Inputs: Result:

R = Ring radius

r = Ring section radius

n = circumvolutions number

15

x = ( R + r × cos(n × t × 360deg)) × cos(t × 360deg)

y = ( R + r × cos(n × t × 360deg)) × sin(t × 360deg)

z = r × sin(n × t × 360deg)
