What's the difference between tab and extrude in unigraphics?

In Siemens NX (formerly known as Unigraphics or UG), the terms "tab" and "extrude" refer to different features and actions within the software. Let's clarify the differences between the two:

1. Tab:

• In the context of Siemens NX, the term "tab" usually refers to the different workbenches or modules available in the software. Siemens NX is organized into various workbenches, each designed for specific tasks in the product development process. Some of the commonly used workbenches include Part Design, Assembly Design, Drafting, and Surfacing.

• When you switch between different workbenches, you are essentially navigating to a different set of tools and functionalities tailored for a specific task. For example, the Part Design workbench provides tools for creating and editing 3D solid models, while the Drafting workbench focuses on creating 2D drawings.

• The "tab" in Siemens NX does not refer to a specific modeling operation but rather to the user interface organization and the set of tools available for a particular task.

2. Extrude:

• Extrude, on the other hand, is a specific modeling operation used to create 3D features by extending a 2D sketch in the third dimension. The extrusion process involves taking a 2D profile (such as a sketch) and extending it along a specified direction to form a 3D solid or surface.

• In Siemens NX, the extrude operation is typically performed within the Part Design workbench. After creating a 2D sketch, you can use the Extrude command to give it depth and create a 3D feature.

Summary:

In summary, "tab" in Siemens NX refers to the workbenches or modules that provide specific sets of tools for different tasks in the software. "Extrude" is a modeling operation within the Part Design workbench, involving the creation of 3D features by extending 2D sketches. The term "tab" is more about the user interface organization, while "extrude" is a specific action within the modeling process.
