2019年3月12日 · Precise boundary-representation (B-rep) solid models power most popular mechanical design tools, as they were the first technology to represent nominal geometry to within micron accuracy. They represent solids as a patchwork of faces joined together by edges that separate a homogeneous inside from the outside.

2024年10月3日 · Convert an implicit model into a CAD format and export it to a CAD program. There are two ways to produce a b-rep in nTop. Your model complexity determines which of the procedures below to use.

2019年3月28日 · For a complex shape, producing one offset at manufacturing resolution could bring the most robust B-rep modelers to their limits. In contrast, by using implicit modeling, nTop easily produces all of the offset layers at manufacturing resolution. Onion shells generated from a …

2024年3月15日 · 在CAD（计算机辅助设计）领域，Brep（边界表示法）是一种重要的数据结构，用于描述三维几何形状。Brep模型由一系列的面、边、顶点等几何元素组成，能够精确地表示复杂的实体模型。本项目是基于Qt5.12和Visual Studio...

2023年4月25日 · Learn how to export nTop models to CAx systems. Applies to: nTop 3.28; Solution: There are different pathways for you to export your geometry out of nTop, you can choose the pathway based on your activity and part complexity from the table below:

2024年12月22日 · • brep（Boundary Representation）主要用于存储拓扑和几何信息，常用于OpenCASCADE等系统中，但不包含实体对象的元数据如名称和颜色。• brep文件不只是记录边界信息，它也记录了构成3D形状的连接的表面元素集合，这些元素定义了内部点和外部点之间的边界。

nTop unlocks faster design iteration without manual modeling–enabling engineering teams to explore more design options, optimize designs faster, and rapidly tailor products to unique project requirements. Rapidly generate and evaluate large sets of design candidates to gain valuable insights before making critical design decisions.

2019年3月12日 · In the early days of nTopology, I wrote a few posts for their blog. This post compares the B-rep and implicit modeling approaches at a high level:B-rep vs. ...

2024年6月25日 · B-rep（Boundary Representation）和implicit modeling是用于建模和设计的两种不同方法。 1. **B-rep模型**： - B-rep模型由拓扑对象组成，这些对象由底层形状或几何图形支持。 这意味着B-rep模型的构建是基于对象之间的拓扑关系，如边、面和体。 - B-rep模型通常用于CAD软件中，能够准确表示物体的表面和边界。 - B-rep模型在处理复杂几何结构时可能会遇到一些问题，例如非流形结果，即四个面接触一个边缘。 2. **Implicit modeling**： - 隐式建模是一 …
