In the rollout, you can define the tangency at the start and end sections in the sweep feature.
The correct answer and explanation is :
Correct Answer:
True
Explanation:
In CAD (Computer-Aided Design) software such as SolidWorks, Inventor, or similar parametric modeling tools, the sweep feature is commonly used to create complex 3D shapes. A sweep creates a solid or surface by moving a profile (a 2D sketch) along a path (another sketch or edge). One important aspect of defining a sweep is how it starts and ends, particularly in relation to the tangency or transition at those endpoints.
When creating a sweep, most advanced CAD software allows users to specify how the profile should blend into or out of existing geometry. This is where tangency control at the start and end comes into play. These controls help ensure a smooth transition between the sweep and the adjoining features or surfaces. The options for tangency conditions at the start and end of a sweep may include:
- None (Default): The sweep starts or ends abruptly without any curvature continuity.
- Direction Vector: You can define a specific vector or direction the profile should follow at the start or end.
- Tangent to Face or Edge: Ensures the sweep begins or ends tangentially to a selected face or edge, creating a smooth and natural flow.
- Curvature Continuous (C2): Provides even higher-level smoothness, where not just the tangents but also the curvature matches adjacent surfaces.
These options allow designers to exert fine control over how their features integrate with the rest of the model, which is crucial in applications where aesthetics, aerodynamics, or fluid dynamics matter — such as automotive or consumer product design.
So, the statement “In the rollout, you can define the tangency at the start and end sections in the sweep feature” is true, and it’s an essential tool for creating seamless, professional-grade 3D models.
