Using isoslope computation (2/2) 创建曲线 修整 scans 创建 3D 曲线 修剪不相交曲线 清理轮廓 修整 scans (1/2) 通过修整 scan创建曲线 修整 scans scans (2/2) Creating a 3D curve (1/3) Creating a 3D curve (2/3) Creating a 3D curve (3/3) Trimming non intersecting curves Cleaning contour 创建曲面 创建规范曲面 创建自由曲面 创建规范曲面 (1/3) This function identifies a canonical surface from a set of digitized points. 创建规范曲面(2/3) 创建规范曲面(3/3) 创建自由曲面 (1/5) This function combines the power of a filling function and a fitting function. 创建自由曲面(2/5) 创建自由曲面(3/5) 创建自由曲面(4/5) 创建自由曲面(5/5) * * CATIA 逆向工程（2） 数字模型 创建 Free Form surfaces 拉伸曲面 修剪 倒角 数字模型 Identify mechanical features Create Scans Create Curves Process curves Create surfaces Define the curvature or radius value or select a point of the polygon Define the analysis type Iso-curvature display Real-time display of curvature value at cursor position Define a filtering value Filtering value set to 500 Filtering value set to 0 Split of the polygone by the isocurvature scans Creation of isocurvature scans Define the angle value Define the compass orientation Creation of the isoslope scan Split of the polygon by the isoslope scan 定义精度 Define manually splitting points on the scan Define the order of each curve’s span Define the maximum number of spans for each curve Define a smoothing factor if necessary Define an angle value for automatic splitting Define the continuity level between two consecutive curves Remove a splitting point Define creation option: Select points on the cloud Constraint point to snap it on the digit Add a point Remove a point Move the manipulator t
