Display a reference set at all assembly levels

This example shows how the Apply to All Assembly Levels option works with subassembly reference sets to provide different display options for an assembly.

In the following figure, a simple vise assembly is shown as it is saved, with the Entire Part condition displayed for every component.

The assembly contains four subassemblies and some piece parts.

As the example begins, the subassemblies do not have any defined reference sets.

	Handle
	Piece parts
	Moving jaw, including handle
	Fixed jaw
	Guide

Open the assembly with the Model reference set displayed for every part that has it, and the Entire Part display condition for other parts.
1. Choose File tab→Open.
2. In the Open dialog box, click Options.
3. In the Assembly Load Options dialog box, in the Reference Sets group, arrange the list with Use Model at the top, and Entire Part second.
4. Click OK.
5. In the Open dialog box, select the vise assembly part and click OK.
The assembly is opened with every Model reference set displayed.
Define a Model reference set in the handle subassembly, and in that reference set, use a simplified body to replace the detailed thread in the screw.
The Model reference set for the screw component has a detailed thread feature.
It is possible to have so much small detail in components that your display regeneration time is affected.
The screw part has three references sets, as shown in the following figure.
Model
Simplified
Symbolic
You can create similar reference sets in any part by constructing whatever geometry you require.
1. With the handle subassembly as the displayed part, display the Model reference set for all components.
2. Change the reference set of the screw to its SIMPLIFIED reference set.
3. If necessary, create a Model reference set in the handle subassembly.
4. Edit the Model to contain all of the components in their current condition.
  When you add a component to a reference set in an assembly, the assembly level reference set records the reference set that the component is displaying.
  If the components are already selected, deselect all components and then select them again with their currently displayed reference set.
5. In the Reference Sets dialog box, from the list, select Model and click Information.
  The Information window should show that for the Model reference set, all components except the screw are displayed with their Model reference sets. The screw is displaying its SIMPLIFIED reference set.
  If the components are not displaying the reference sets described, remove the incorrectly displayed components from the reference set, display the reference sets you want for those components, and add the components to the reference set again.
6. Save the handle subassembly, and close all parts.
Open the vise assembly to display the Model reference set you created in the handle subassembly, with a simplified display of the screw.
You can use the same steps as you used to open the assembly initially, except this time, in the Assembly Load Options dialog box, you must clear the Apply to All Assembly Levels check box.
The assembly shows the model reference set for all components except the screw.
This happens for the following reasons:
- The handle subassembly has a model reference set that includes the simplified reference set of the screw and the model reference set of the other piece parts.
- The Apply to All Assembly Levels check box is clear, so the search for reference sets ends at the handle subassembly. The handle subassembly is opened displaying the model reference set that you defined.
- The other subassemblies do not contain a model reference set, so they are loaded displaying their Entire Part reference sets. The Entire Part is only a display condition, not a true reference set, so the search for model reference sets continues to the subassembly piece parts.
To open the assembly as it is now saved, and to display the Model reference set for all piece parts, select the Apply to All Assembly Levels check box. Although the subassembly Model reference set is found, each piece part is checked and, if it has a Model reference set, the Model reference set is displayed.
Define a Drawing reference set in the handle subassembly.
The Model reference set with its detail thread is too complicated for most drawing requirements, and the SIMPLIFIED reference set does not show the threads.
A drawing reference set typically includes simplified geometry, special symbols, silhouettes, or any other geometry that renders your drawing clearly and permits fast view display and update.
1. With the handle subassembly as the displayed part, display the model reference set for all components except the screw.
2. For the screw, display the SYMBOLIC reference set.
3. Define a DRAWING reference set, and add all of the components with their currently displayed reference sets.
4. Save the subassembly and close all parts.
Open the assembly with the DRAWING reference set at the top of the hierarchal list.
1. In the Assembly Load Options dialog box, in the Reference Sets group, arrange the list with DRAWING at the top, Use Model second, and Entire Part third.
2. If necessary, clear the Apply to All Assembly Levels check box.
The assembly again shows the model reference set for all components except the screw. The screw is displayed with its SYMBOLIC reference set.
This happens for the following reasons:
- The handle subassembly has a DRAWING reference set that includes the SYMBOLIC reference set of the screw and the model reference set of the other piece parts.
- The Apply to All Assembly Levels check box is clear, so the search for reference sets ends at the handle subassembly. The handle subassembly is opened displaying the DRAWING reference set that you defined.
- The other subassemblies do not contain any reference set, so they are loaded displaying their Entire Part reference sets. The Entire Part is only a display condition, not a true reference set, so the search for reference sets continues to the subassembly piece parts.
- None of the piece parts has a DRAWING reference set, but they all have a Model reference set.

NX Reference Sets

In today’s blog you will discover What a Reference Set is while engaging in NX CAD. Without further ado, let’s get to it.

Reference Sets

Reference Sets are used to control the display of a component or subassembly in higher level assemblies.

In this blog, we cover

What is a reference set, with some examples
Types of reference sets
What is an “Excluded” Reference Set?
How to make a User Named Reference set source(s), Siemen’s documentation

There are two types of reference sets:

Automatic sets that are managed by NX.
Model, Empty, Entire part
User-defined sets.

As you create geometry, NX automatically defines the Model Reference set. This Model is comprised of solid geometry. Not included: datums, sketches or other construction geometry.

Empty and Entire part are self-explanatory. For the Empty use case, see below

User-Defined Reference sets are collections of objects that you assign a name to, in a piece part or subassembly.

For a piece part, such as an optics lens, model geometry with datum CYS is one option
For a rotating part, add a direction arrow
For an odd shape, add alignment datum axis or wireframe direction arrow
In a routing scenario, a port assignment reference set may be defined for a component
And so on…

This is an optic for laser application.

How would you align it?

A focal plane is also required for object/image distance

Solution: Add a datum plane at focus, then create new set

Use of reference sets:

Filter unwanted objects in a component part so that they do not appear in the assembly.
Add additional objects to assist in interpreting the assembling

While in use:

Filter unwanted objects in a component part so that they do not appear in the assembly.
Add additional objects to assist in interpreting the assemby
Represent a component part in the assembly with alternative geometry in complement with the solid body

Laser Attachment w/ beam path placed at focal plane

In the Entire Part reference set case, all of the part objects as datums, planes, lines, are shown in the assembly. This can be visually cluttered depending on the component.

What is an “Excluded Reference Set?”

In an assembly, some parts might not be visible.

When you try to make these parts visible by clicking the checkbox, this message appears

You cannot make the part visible by changing visibility options or by using the “Show and Hide” commands.

Now what?

Right click on the part in the assembly navigator.
Move cursor onto the “Replace Source Set” in the list.
The list will open.
Select a option such as “Entire Part” or “Model”

How to make a User Named Source set

Objects that can be a member of a reference set include (partial listing)

Geometry
Datums
Coordinate systems
Pattern objects
Subassembly components

Additional objects that would not a set are identified as:

Promotions
Individual datums that belong to a Datum CSYS. [You can add an entire Datum CSYS.]
View-dependent objects. Their visibility is controlled by the view in which they are displayed, not by the set in use.

Example of a user defined reference sets (source: Siemens Documentation)

Determine the content of existing reference sets by looking in the Reference Sets folder.

You will need to enable the ‘Display Reference Sets Folder’ option in the customer defaults settings.

User defined Source Sets (in alphanumeric order) followed by system defined source sets

Same order is displayed when you use ‘Replace Source Set’ in the assembly.

‘Source Sets’ node is available in the part navigator when ‘Timestamp Order’ is on or off with the difference as noted below.

Source sets Folder – Timestamp Order is On

When Timestamp Order is on, this source sets folder displays only the sets itself and their first-level children, such as solid bodies, curves, or sketches.

Source sets Folder – Timestamp Order is Off

When Timestamp Order is off, children will show their construction details, such as Features, Curves and Dimensions, External Reference, Reference.

A well-managed reference set methodology allows:

Faster load times.
Reduced memory usage.
Less cluttered graphics displays.

Also, there are additional training opportunities available on our Website. We are just one click away from assisting you go beyond may already know or would like to learn..
