Geometric Expressions nx interview question and answersġ1) What is Direct Modeling or Synchronous Modeling?ĭirect modeling techniques represents extended capabilities for some of the more basic Unigraphics functions. By changing the expressions that control a specific parameter, you can re-size or re-position features of a solid modelģ. With expressions, you can easily apply major edits to a model. 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.Įxpressions are mathematical or conditional equations used to control the parameters of a model. This option let you create a family of parts by creating a template part. You can also decide whether you want he Extract Body feature to update when the original body is changed. Features can then be added to Extract Body feature without appearing on the original body. This option create an associate copy of an entire body in part file. (Example: In Machining model you can add wave link of Casting model and perform the machining operations)

Once you have a wave linked boy you can perform operations on it. This option create an associate copy of composite curve, sketch, datum, point, face, body, mirror body of part file in assembly file. 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. 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 promote body remains associative to the original body, which is referred to as the base body. 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. You can define the shape and function of features, and create hierarchical libraries of features that are tailored to our need.

You can create and add the user defined features (UDFs) to target solids. We can create our own form features that automate commonly used design elements. User defined feature is used to create the objects of different sizes in a single file. Note: Save your file where command prompt showing location Example:- C:/users/username Ug_convert_part (space) -in (space) 1234.prt We can convert a file created in mm to inches by using UG command prompt. 4) How to convert a file created in mm to inches (conversion of units) in UG?
