Direct modeling techniques represents extended capabilities for some of the more basic Unigraphics functions. Among these are face oriented operations, constraint based methods, blend regeneration and independence of feature history. You can use Direct modeling functions on models that have been imported from other CAD systems and are non-parametric. There are colors in UG. There are Layers in UG.

When you open Unigraphics, you are in the Gateway application because this application is a pre-requisite to all other application. The same model is used from conceptual design to the Drafting, Assembly, Analysis and Manufacturing. The idea of a virtual assembly taken to its logical conclusion leads to Master Model paradigm. If you change any thing in Master Model, it will reflect in all other applications.
It is a PDM Product Data Management software which helps the organisation effectively control the design, development, analysis, manufacturing through out the product of life cycle.
We can convert a file created in mm to inches by using UG command prompt. User defined feature is used to create the objects of different sizes in a single file. We can create our own form features that automate commonly used design elements. You can create and add the user defined features UDFs to target solids. You can define the shape and function of features, and create hierarchical libraries of features that are tailored to our need. When you have an assembly that is work part, this option lets you promote a body from a loaded assembly component to the level of the assembly.
The promote body remains associative to the original body, which is referred to as the base body. Once you have promote a body, you can perform operations on it, such as adding features, performing Boolean operations between it and other bodies, and so on. The effects of these operations are only visible at the level of the assembly work part in which the promote was created, and in any other assembly that references that part.
This option create an associate copy of composite curve, sketch, datum, point, face, body, mirror body of part file in assembly file. Once you have a wave linked boy you can perform operations on it. Example: In Machining model you can add wave link of Casting model and perform the machining operations 8 What is Extract Body? This option create an associate copy of an entire body in part file. Features can then be added to Extract Body feature without appearing on the original body. You can also decide whether you want he Extract Body feature to update when the original body is changed.
This option let you create a family of parts by creating a template part. You can use the Unigraphics spread sheet via the Create button on the Part Families dialog to create a table describing the various part family members. Expressions are mathematical or conditional equations used to control the parameters of a model.
With expressions, you can easily apply major edits to a model. By changing the expressions that control a specific parameter, you can re-size or re-position features of a solid model Three types of Expressions are there 1. Airthmatic Expressions.

Why it is used? Datum Plane is reference feature that can be used to as construction tool in building the model. Datum Axis, which is a reference object you can use to create other objects, such as Datum planes, revolved features, and extruded bodies. Datum Axis can be either relative or fixed.
