4 MBD Features in Creo 4 (That Could Make You 75% Faster)

Written By: Madhavi Ramesh

For those using model-based definition (MBD), the recent release of Creo 4.0 makes it easier to create and validate geometric dimensioning and tolerancing (GD&T) annotations. In fact, new productivity-focused enhancements could mean you’ll get your work done with 75% fewer mouse clicks.

MBD establishes standards and requirements for tolerances, dimensional data, and other digital design annotations on 3D solid models. Creo 4.0 includes a number of new and enhanced features that support the effort to apply GD&T data to 3D models.

 In this blog post, I’llto each of these 4 areas:

Datum Feature Symbol

Datum features and datum targets are important for those using GD&T in their work. Processes for creating both are easier and more efficient in Creo 4.0.

First, let’s take a look at 4 types of Creo 4.0 updates that improve processes for working with datum feature symbols:

1) Creation and editing

2) Automatic naming

3) Semantic references

4) Additional text

Datum Target Symbol

Just like how it’s easier to work with datum feature symbols, in Creo 4.0, you can quickly create and edit datum target annotations. You’ll notice many of the enhancements related to datum feature symbols are also available for datum feature targets.

 Here are 4 types of Creo 4.0 updates that improve processes for working with datum target symbols: 

1) Creation and editing

2) Semantic reference to datum feature symbol

3) Built-in standard target areas

4) Standards support

Geometric Tolerance

When you’re working with geometric tolerances, you might notice that Creo Parametric now supports a composite tolerance definition of more than two rows. You can create more than two rows of composite tolerance, with flexible tolerance value and datum input fields for each row.

 Tolerance rows

Create more than two rows of tolerances. 

Additionally, you’ll notice 4 types of geometric tolerance-related enhancements, including:

1) Creation and editing

2) Text inputs for tolerance value and datum compartments

3) Standards support

4) Integrated Datum Reference Frame (DRF)


When you’re working with dimensions, you can easily edit properties using the contextual ribbon menu. The creation workflow is not interrupted. So, there’s no need to exit dimension creation to edit properties of any dimension.

 In Creo 4.0, you’ll find these 4 types of updates that improve processes for working with dimensions:

1) Creation and editing

2) Improved control of dimension orientation

3) Improved dimension text

4) Semantic references

 Contextual menu

Contextual menus streamline creation and editing processes.


Bonus! General Enhancements

In addition to the enhancements related to the 4 areas above, Creo 4.0 has a number of general MBD-related enhancements focused on improving productivity. For example, annotations can now be created and manipulated really easily. And, you’ll find these other notable updates:

Standalone annotation behaviors

Improved appearance of coordinate systems

Dynamic movement of annotations

ASME and ISO standard text and symbol fonts

Option to avoid clipping annotations by cross-section
