Summary
NX™ I-deas™ Master Modeler software is the core design module for the NX I-deas product set, providing comprehensive three-dimensional solid modeling capabilities for companies designing complex parts. Master Modeler includes powerful tools for capturing design intent in part features, which are easily edited and updated to support real-time design modification processes. The NX I-deas design environment supports a mix of solid and open-surface geometry using the same set of design-intent driven operations. Three-dimensional models designed in Master Modeler are the basis for all downstream activities in NX I-deas.

Foundation tools for feature-based, variational solid modeling
Master Modeler is a high-performance 3D design system, and is the multi- purpose geometric modeling foundation of NX I-deas. You work with a user interface tuned for productivity to design complex mechanical parts in an intuitive feature-based solid modeling environment. The solids-based approach aids design productivity by simplifying construction of complex geometry, facilitating design changes, automatically removing hidden lines, directly calculating mass properties and providing an accurate part definition for NC machining. In addition to being a design system, Master Modeler is also the common geometric modeling foundation of NX I-deas. Three- dimensional models designed in Master Modeler are the basis for all downstream activities in NX I-deas, including assembly modeling, advanced digital simulation, digital manufacturing and two- - and three-dimensional annotation and documentation.

Master Modeler provides a complete suite of feature-based variational solid modeling tools to increase the productivity of designing the manufacturing components of any complexity

An integrated data management system provides the foundation for concurrent engineering by maintaining associativity across the master model, assemblies, 2D drawings and finite element models. Just one instance of a part in the master database can drive any number of associative, linked application studies, such as assembly packaging models, layout and detailed drawings, stress calculations and design optimizations.

Part modeling
Master Modeler is the core, feature-based, variational modeler for complex associative geometry creation with options including open part or solid geometry, variational constraints, variational and parametric design features, associative coordinate systems and engineering equations that drive the geometry. Feature geometry may be constructed “in place” or positioned “with relations” to other geometry. The “dynamic navigator” anticipates user intent and pre-highlights geometry and constraints, making part modeling easy and efficient. “Material side” allows construct operations on open parts. Construct operations include the common operations of add, cut, join and intersect; as well as more advanced operations such as partition, join with partition, merge volumes, stitch surfaces and split surfaces. These operations are supported between discrete parts or within a single part. Advanced features such as variational sweep allow the user to model very complex shapes in a single feature that may be impossible or require many steps to model in other systems.

Part modification
The graphical history tree browser in Master Modeler makes part modification easy. You can change the construct operation type; modify the wireframe sketch; delete, suppress or replace a feature; modify feature parameters; or associatively copy a feature within the part. The person making modifications to a part is often not the same one who originally designed the part. The replayable design history helps others understand how the part was modeled and the original design intent of the part features. Features can be renamed to identify key features in the part history and convey their design intent. Search capabilities allow you to easily find features within a complex part history. You can rollback to an earlier feature in the history, allowing you to insert features at this point, then update the part to include the remaining features.
