Generative Shape Design

This page deals with the Generative Shape Design options:

● The General tab lets you define the tolerant modeling, axes visualization and groups options

● The Work On Support tab lets you define the work on support and the work on support 3D

options

● Merging distance: default value defining the distance below which elements are to be joined or healed.

This option is available with the following commands: Join and Healing

By default, this option is set to 0.001mm

● Tolerant laydown: in case the lay down of an input guide on a surface fails, you can check the Tolerant laydown button When activated, a fixed lay down tolerance of 0.1mm is applied

This option is available with the following commands: Parallel Curve, Sweep, Multi-Sections Surface, Blend, Split, Curve Smooth,

Fill and Extrapol

By default, this

option is unchecked

Here is a scenario with

the Sweep command

1 Create a tolerant swept surface and define a

Deviation from guide of 0.1 mm

In our scenario

we created a swept surface using an implicit linear profile and the ''two limits'' sub-type We

created Curve.1 and Curve.2 as the guide curves

2 Create a parallel curve of Curve.1 using the swept surface as the support

The creation of the parallel curve fails

An error message opens informing you that the guide curve does not lie on the swept

3 Check the

Tolerant laydown

option

4 Perform step 2 again

The creation of the parallel curve is successful

It is advised not to use a wire that lies on the edge of the sweep when working with the Tolerant laydown

option

Output parameters

● Choose the Continuity Type:

❍ None: deactivates the smoothing result

❍ Tangency: enhances the current continuity to tangent continuity

❍ Curvature: enhances the current continuity to curvature continuity

This option is available with the following commands: Project and Parallel Curve

By default, the option is None

● You can specify a Maximum deviation to set the allowed deviation between the initial element and the smoothed element by entering a value or using the spinners

By default, this option is set to 0.001mm

This option is available with the following commands: Project, Parallel Curve, Sweep, Multi-Sections Surface, and Curve Smooth

For the Sweep and Multi-Sections Surface commands, only the Deviation parameter can be defined from

Tools -> Options (the Angular correction parameter cannot be defined here) The Deviation and

Angular correction will be activated only if the smoothing type is set to Tangency or Curvature

Axes

Visualization

Uncheck the Axes visualization limited to the bounding box of the input button to visualize an infinite axis in the 3D geometry.

By default this option is unchecked

● This option is only available when creating a new feature

● It is only available for features accessible in the Generative Shape Design workbench All other features will not be included in the group even if the option is checked

For further information, please refer to the Managing Groups chapter.

Stacked

Analysis

Check the Stacked analysis default behavior set as temporary option to automatically create a

temporary analysis when checking connections between surfaces or curves

By default this option is unchecked

This option is only available with the Offset command

Working with a Support

This page deals with the following settings:

By default, this option is set to 100mm for primary spacing and 10 graduations

● If you wish, you can define another scale for the Second direction scale (V for vertical), thus allowing distortions of the grid Check the Allow distortions option to activate the

Primary spacing and Graduations fields of the second direction.

By default, this option is unchecked

Work On Support 3D

Grids definition

Define the default values for the grids, by defining Labels names and Primary Spacing

values for each direction

By default, the Labels are set to X, Y, and Z for the first, second and third directions, and the Primary Spacing is set to 100mm for all directions

Grids customization

● Define the Grid labels unit, that is the coefficient of division for all straight lines units.For example, the grid label unit is set to 1 and the X label for one line is set to 500 If you modify the grid label unit to 10, the X label will be 50

By default, this option is set to 1

● Define the Automatic Scale Factor, that is the scale to be used when the grid becomes too small The factor is comprised between 2 to 10

By default, this option is set to 10

● Define the Maximum lines number to be displayed on the screen, from 70 up to 500 lines

By default, this option is set to 70

All these values will be used as the default values when creating a support

For further information, please refer to the Working With a Support and Working With a 3D Support chapters.

Glossary

A

affinity An operation in which an element is transformed by applying X, Y, Z

affinity ratios with respect to a reference axis system

C

child A status defining the hierarchical relation between a feature or

element and another feature or element

constraint A geometric or dimension relation between two elements

E

extrapolate An operation in which an element is extended a specified amount

while respecting tangency or curvature conditions Typically a surface boundary can be selected for in order to extrapolate the surface a specified length

extruded surface A surface that is obtained by extruding a profile along a specified

direction

F

feature A component of a part

fill surface A surface that is obtained by filling a closed boundary that is made up

from a number of segments

fillet A curved surface of a constant or variable radius that is tangent to

and joins two surfaces Together these three surfaces form either an inner or outer corner

G

guiding curve A curve, intersecting with a profile, and along which this profile is

swept See also spine

J

join An operation in which adjacent curves or adjacent curves can be

assembled to make up one element

M

multi-section surface A surface that is obtained by sweeping one or more planar section

curves along a spine, which may be automatically computed or defined The surface can be made to follow one or more guide curves

offset surface A surface that is obtained by offsetting an existing surface a specified

distance

P

parent A status defining the hierarchical relation between a feature or

element and another feature or element

part A 3D entity obtained by combining different features It is the content

of a CATPart document

part body A component of a part made of one or several features

profile An open or closed shape including arcs and lines

R

revolution surface A surface that is obtained by revolving a profile around an axis

rotate An operation in which an element is rotated by a specified angle about

an given axis

S

scaling An operation that resizes an element to a percentage of its initial size

sketch A set of geometric elements created in the Sketcher workbench For

instance, a sketch may include a profile, construction lines and points

spine A curve which normal planes are used to position a profile when

creating a surface (lofted or swept surface for example) The profile does not necessarily intersect with this spine See also guiding curve

split An operation in which one element is cut by another element

swept surface A surface obtained by sweeping a profile in planes normal to a spine

curve while taking other user-defined parameters (such as guide curves and reference elements) into account

symmetry An operation in which an element is transformed by means of a mirror

symmetry with respect to a reference plane, line or point

T

translate An operation in which an element is displaced a specified distance

along a given direction

trim An operation in which two element cut each other mutually

W

the outline of a 3D object
