In this lecture we will learn about:

• Geometry Import Properties

• CAD Connections

• Uni/Bi-Directional Connectivity

• Parameters handling

• Some advanced topics

Introduction to Advanced Topics




are import and data transfer rel

• applicable for imports• Most of the settings done through

– “Basic Geometry Options”

– and “Advanced Geometry Options”

• Basic Properties

– ‘Parameters’ option for importing

parameters defined in CAD package

– ‘Parameter Key’ filters the parameters

from CAD that enter Workbench

• If not specified, all parameters enter WB

Geometry Properties (1)

Geometry properties




• Basic Properties (con’t)

– Named Selection

• Define in CAD & transfer to WB

• Filter under WB

– Set to NS (by default) – remove it to import all parameters

• Activate WB option

– Geometry import / named selections

• Advanced Properties

– Select ‘Use Associativity’ to establish association between CAD and

WB

– Import defined CAD properties :

• Coordinate Systems,

• Work Points, etc.

– Smart CAD Update

•

Changes made in other options get updated in the mode

Geometry Properties (2)

In workbench project page

• File/import

• Import

• Uni-directional connectivity

• Import neutral/native CAD files directly into Design Modeler

CAD Connections : Approach I

Import IGeometry cell on project page

Import IIIn Design Mo

• Multiple

• Appends

Import III



• Export parameters from CAD to Workbench

• Parameter change in CAD reflects in

Workbench and vice versa

• Direct connection in UG NX

• Bi-directional connectivity

• Launch Workbench from CAD System

CAD Connections : Approach II

Bi-directional CAD connectivity• Attach to Active CAD Geome

• Imports active CAD geomet

• Can attach only saved CAD s

Bi-directional import fr



• helps execute a set of operations repeatedly with different input values

• Useful for analyzing multiple design points By modifying geometry/topology parameters

• Parameters can be either used for : Sketch dimensions, Plane creation inputs, 3D operation values, etc.

• Parameters can be linked with each other through expressions Defined in Design Modeler or Workbench

• Parameters can be controlled from Workbench No need for Design Modeler to be opened

CAD Connection

CAD Connections & Parameterization

Parameterization

What is it ?



Types of Parameters

Changes the dimensions or locations of a givenfeature

• Does not necessarily change the total

number of entities in the model

Geometric parameters

Modifying the feature itself by aremoving geometry

• Can change total number of

model

Topological parameters

Parameterized

number of copies

in a pattern

DM Param




Procedure

• Any input prefixed with the “□” symbol can be parameterized

–Toggle “□” to “D” to parameterize that particular input

• Default Parameter Name Pattern

– Feature Name.Dimension Reference

• Parameter name can be changed

Examples:

Creating Parameters in Design Modele

A dimension reference (H1) for a sketch

created on the XYPlane = XYPlane.H1

A dime

Extrud




Accessible from the Toolbar or Tools menu

• Design Parameters tab – List the existing parameters & assigned values

• Parameter/Dimension Assignments tab

– Contains expressions

• relating the original dimension reference to the

value set in the Design Parameters tab

Parameter Manager

This 2 defined parameters become obsolete

and can be suppressed (or deleted)

Create the needed expr

‟Check” to evaluate




• Parameters created into Design Modeler can either be managed in:

– Parameter Editor in DM

– Parameter Set in WB

Parameter Manager

Expression can be created in the

Outline of All Parameters in WB

Multiple Design Points can b

different values of the param

independent variable

Updated in background




Miscellaneous Topics




Advanced Sweep Options

Sweep Options

• Scale

–

Taper or expand the Profile as it is sweptalong the path of Sweep

• Twist Specification

– No Twist : Helical sweep is not created

– Turns : Specify number of turns to complete

over the path length

–Pitch : Specify length per 1 full turn

4m




• Using “By Direction” option, one can align bodies

alignment vertices for aligning axes of bodies and

with respect to each other.

Body Operation: Move, Align and Orien

• User needs to select bod

Coordinate File for 3D Curve

A coordinate file must be a simple text file in the following format:

•After a pound sign (#), everything else on that line is considered a

comment and is ignored.

•Empty lines are ignored.•Data consists of five fields, all on one line, separated by spaces

and/or tabs:

– Group number (integer)

– Point number (integer)

– X coordinate

– Y coordinate

– Z coordinate

•A data line with the same Group number and Sequence number as a

previous data line is an error. A data line cannot contain the same

Group number and Sequence number as a previous data line.

•For a closed curve, the point number of the last line should be 0. In

this case, the coordinate fields are ignored.




Managing External Files

The Workbench project file structure provides a directory named“user_files” which may be used to store CAD, or any other files you

wish to associate with the project.

If you have used imported geometry in your Workbench project and

subsequently intend to transfer the project to another computer

you can move or place a copy of the required files in the user_filesfolder.

When the project is reopened Workbench will prompt you to locate

the file.• From the View Menu, select Files.• Right click on the relevant file in the list and select Repair “filename.xxx”.

• Browse to the file in the user_files folder.• The new path will be saved with the project.

Named Selections : Propagation Prope

Original Selection

NoYes

Yes – Selection propagates to all resultant entities

No – Selection propagates to just one of the resultant entities or destroyed
