Topology optimization: A design optimization technique in CAD software that uses mathematical algorithms to determine the optimal shape or distribution of material within a given design space, based on predefined constraints and objectives.

Tracking vectors: Vectors or lines in CAD software that provide visual guides or reference paths for drawing or aligning objects or elements, allowing for precise positioning or measurement.

Transparently: In CAD software, the ability to see or display objects or elements with transparency, allowing for overlaying or visualizing multiple layers or components simultaneously.

Trim: A function that removes portions of objects that extend beyond specified boundaries.

Trim Surface: A function that removes portions of a surface that extend beyond specified boundaries, creating a clean and precise edge.

TurboLux: TurboLux is a physically based rendering (PBR) solution used in TurboCAD. It simulates the flow of light according to physical equations, producing highly realistic images. TurboLux supports various materials and lighting setups, making it ideal for creating photorealistic renderings.

U3D: U3D (Universal 3D) is a compressed file format standard for 3D computer graphics data. TurboCAD supports importing U3D files.

Under-constrained: A condition in CAD software where an object, element, or design does not have enough geometric or dimensional constraints to fully define its position or behavior, resulting in potential instability or unintended variations.

Undo/Redo: Functions that allow users to reverse or reapply the most recent actions or changes made to a CAD model.

Unfold: A function that displays a sheet metal part in its flat state, showing all bends and cutouts as they would appear before bending.

Unidirectional dimensioning: A dimensioning method in CAD software where dimensions are placed in a single direction or orientation, typically aligned with a specific axis or edge.

Unilateral tolerance: A tolerance specification in CAD software that allows variation or deviation in only one direction or side of a feature or dimension, such as allowing only positive or negative deviations.

Unit block: A standardized or predefined block or component in CAD software that represents a specific unit of measurement, typically used for scale representation or dimensional reference.

Unload: The action of removing or unloading a referenced file or external reference (xref) from a CAD drawing or model, temporarily excluding it from the current session or workspace.

Unselected grips: The grips or handles associated with objects or elements in a CAD drawing or model that are not currently selected or activated for editing or manipulation.

Update: The process of refreshing or updating the display or content of a CAD drawing or model to reflect changes made to objects, properties, or parameters.

User coordinate system (UCS): A customizable coordinate system in CAD software that allows users to define a specific origin, orientation, and scale for drawing or modeling purposes, providing a local reference frame.

User parameters: Customizable variables or values defined by the user in CAD software that control specific aspects, behaviors, or properties of objects, elements, or designs.

Value set: A defined range or set of allowable values for a parameter, variable, or attribute in CAD software, constraining its possible options or inputs.

Variable: A named entity or symbol in CAD software that represents a value, property, or attribute, which can be modified or assigned different values throughout the drawing or model.

VDA-FS: A file format standard for the exchange of CAD data, primarily used in the automotive industry.

Vector graphics: A type of graphic representation in CAD software that uses mathematical formulas or equations to define geometric shapes, lines, curves, and other graphical elements, allowing for scalable and resolution-independent rendering.

Verb/noun selection: A method of selecting objects or elements in CAD software where the selection order follows a specific sequence of action verbs and object nouns, ensuring clear and unambiguous selection.

Vertex: A point of intersection or connection between lines, curves, or edges in a CAD drawing or model, defining the corners or endpoints of polygons, surfaces, or 3D objects.

View: In CAD software, a specific representation or perspective of a drawing or model, showing a particular aspect, angle, or detail of the design.

Virtual prototyping: The use of CAD software and computer simulations to create and evaluate virtual prototypes of products or designs, allowing for testing, analysis, and validation before physical production.

Wireframe modeling: A method of 3D modeling in CAD software that represents objects or structures using only lines and curves, without surface or solid representations, providing a simplified visual representation.

Workgroup CAD: A collaborative CAD environment or system where multiple users can work on a shared project, accessing and modifying drawings, models, or data concurrently.

Workplane: A reference plane or surface in CAD software that serves as the primary drawing or modeling plane, providing a consistent and controlled orientation for creating or manipulating objects or elements.

XREF: XREF (External reference) is an external CAD file or drawing that is linked or referenced within another CAD drawing, allowing for efficient reuse of content and maintaining consistency.

Zero: The reference point or origin in a coordinate system in CAD software, typically represented by the coordinates (0, 0, 0) and used as the starting point for measurements and positioning.

Zoom: The action of changing the view or scale of a CAD drawing or model to make it appear larger or smaller on the screen, allowing for closer examination or overview of details.
