三维建模
我们很自豪能够与 ACIS 一起率先开发几何内核。如今,我们提供的解决方案可满足您的三维几何表示需求。无论您需要连续还是离散的 B-Rep 建模器,我们都能为您的特定应用需求提供解决方案。
更多信息曲面建模让您能够直观地展现物体的外观和轮廓——也就是它的表面。
该对象可以是机械部件,例如发动机,或是复杂的有机形态,例如动物。
无论您设计什么产品,曲面建模都涉及定义物体的外部曲线和形状。
与实体建模不同,曲面模型在几何形状和物理属性上都不精确,没有明确的质量属性且没有厚度,这使得设计师能够以实体建模无法实现的方式修改模型。
然而,曲面模型本质上是空心的,因此不能像实体模型那样被切割开。
另外,请注意,曲面可以根据需要以NURBS或多边形的形式呈现。在Solidworks中,曲面建模通常采用NURBS。
曲面建模利用B样条和贝塞尔方程来定义物体在三维空间中呈现的特征,并广泛应用于建筑插图、电子游戏3D动画等领域。它相对于其他技术具有一些显著优势:
曲面建模与实体建模各有优势与局限,优秀的设计师需要了解如何利用它们,在CAD环境中高效且准确地设计模型。
虽然实体模型可以进行切割和拉伸,但曲面建模更适合于塑造网格对象。设计师可以通过“拖动”边缘来操控网格面,设置平滑度等,从而完善设计。
