Question 1- What is a part file?

NX files use an extension PRT and are sometimes called part files.

They can contain:

Assembly components

Part geometry

Drawings

This is equivalent to mergingI-deas ASM, PRT, and DWGlibrary item types into

one consistent file type. This provides advantages for

top-down assembly modelingand other modeling techniques.

Question 1- What is a part file?

How do I change the units of the part file?

Select default units when you create the file.

Enter numbers followed by units in entry boxes.

(mm, cm, km, in., ft, mi, etc.)

When creating expressions, choose a units type, then a

unit. Use the units conversion utility to convert the units of all

geometry, drawings, dimensions, parameters, and

expressions in the file.


7/23Page 7



Question 2- Where is my model file?

There is no model file.

NX session:

Your can have multiple open files, similar

to other Windows applications. TheWindow menu shows open files.

Only one file is displayed at a time.

The displayed file can be a part or

assembly.


8/23Page 8




Where is Manage Bins?

There arent any bins.

Open files directly from Teamcenter.

Use Teamcenter folders

to organize current projects.

Use the Window menu to

select a file to display

from among open files.


9/23Page 9




How do I open a file for reference?

Default behavior in Teamcenter Integration for NX :

If multiple users have the same file open, the first user to modify

the file locks it.

Control file access using:

Personal and Group ownership Define who has access to

modify a file.

Baseline versionsCreate a frozen snapshot of versions for

different purposes.

Status Define a status value to baseline versions to identify

them.

Typical status values: Shared, In Review, Released.

NX Revision rules define the status of parts to open.

Question 3- Why cant I edit a feature?

You must switch from the Gateway application to the Modeling application.You can view history, but not modify it in the Gateway application


11/23Page 11



Question 4- What is the difference between

Edit and Edit with Rollback?

These are similar to the I-deas options Quick Wireframe and Wireframe.

Edit

Edit with Rollback


12/23Page 12



Question 5- Why are there still 2 free DOF in my sketch?

The first sketch line is

not an inferred ground

as in I-deas.

To fully constrain a

sketch, you must fully

constrain it to an

external reference.


13/23Page 13



Question 5- Why are there still 2 free DOF in my sketch?

Can NX work in polar coordinates? (Simulation users ask this.)

Preferences Grid and Workplane


14/23Page 14



Question 6- How do I create reference curves?

The term reference curves is different in I-deas and NX.

Reference curves in I-deas are a way to convert a sketch to afeature to use in multiple features.

Reference curves in NX are construction lines in a sketch.

To use a sketch in multiple features in NX, keep the sketch externalto the feature.

Convert sketch curves to reference curves to identify them asconstruction lines that will not participate in an Extrude or otherfeature.


15/23Page 15



Question 7- What does it mean to keep the Boolean

feature separate from the Extrude feature?

In I-deas, you perform Boolean operations on

two parts to create a bushy history tree.

In NX, you perform Boolean operations on

multiple solid bodies in the same file to use the

equivalent modeling technique.

1. Use the Extrude command with the

Boolean option None to create a separate

solid body in the same file.

2. Use other commands on the resulting solid

body.3. Use the Unite, Subtract, or Intersect

command to combine the bodies.

Question 7- What does it mean to keep the Boolean

feature separate from the Extrude feature?

Question 8- Where is the Display Filter?

The Hide and Show

command on the Utility

toolbar is similar to the I-deas

Display Filter.

Layers can also be used to

control visibility.

Reference sets can be used

to control part geometry

displayed in assemblies.

Question 9- How can I work with multiple parts

at the same time?

NX does not have a workbench concept.

The I-deas workbench provided:

A clipboard to move geometry between parts

A context to design mating parts non-associatively

(Yellow non-associative sketch curves created using Focus)

To replace these functions in NX:

Use Copy and Paste

Work in an assembly context

Question 9- How can I work with multiple parts

at the same time?

Designing parts in an assembly context

In NX 6, there are two additions to the Selection bar

Selection Scope

Select fromthe Work part orthe entire assembly

Create Interpart Link

Turn off to work non-associativelysimilar to yellow point Focusin I-deas.

Turn on to create associative links.

Question 9- How can I work with multiple parts at

the same time?

Support Plate

Base

Extrude using

Until Extended,select face from

the Support Plate.

Create sketch points aligned

to the circle centers on the

Base. Use the Hole command

to create the holes.


21/23



Question 10- Do I have to ground the first assembly component?

Assembly Mating Conditions (pre-NX 5) were directional, and the first

component in a from/to chain was assumed grounded.

NX assembly constraints are similar to I-deas assembly constraints.

Either component can move.

It is a good practice to use a Fix constraint

to ground components that should not move.


22/23



Conclusion

I-deas users are finding thatlearning NX is not difficult,

once they learn the major

differences.

An I-deas to NX Transition

class is available.

Use the I-deas to NX
