Mastercam 用 Curve One Edge 快速生成夹具几何
Create Fixture Geometry Faster with Curve One Edge
Mastercam 的 Curve One Edge 功能可从现有模型特征直接生成线框几何，用于快速创建夹具轮廓等下游任务。使用时先在 2D 模式下把构图面置于零件下方，再从线框选项卡启动该功能，单击所选模型边即转换为线框实体，并投影到该构图面上形成夹具设计轮廓。该功能完全动态，再次点击已选实体即可移除，无需清理。配合 AutoCursor 仅启用边选择时，可逐条选边，或按住 Shift 选中一条边自动捕获所有相切边；启用环选择可从模型上任意封闭环生成线框，面选择则自动为该面的每条边生成线框。系统支持在同一次操作中混合边、环、面选择并动态增删实体，且支持 2D 与 3D 构图模式。除夹具设计外，该功能还用于生成刀路控制几何、构建线框、参考曲线、支撑结构、安装特征及简化模型修改，并支持实体、曲面和网格实体。
In manufacturing, creating additional geometry is often a necessary step in preparing parts for machining. Whether you are designing fixtures, adding mounting components, or generating supporting geometry to control toolpaths, having a quick and efficient way to extract model edges can save valuable programming time.
That is where the Curve One Edge function shines.
Simple, intuitive, and incredibly versatile, Curve One Edge allows users to rapidly generate wireframe geometry directly from existing model features, making fixture creation and other downstream tasks significantly easier.
Building Fixture Profiles in Seconds
Imagine you need to create a fixture for a part and require a set of profiles to extrude into supporting geometry.
The process begins by positioning a construction plane in 2D mode, with the Z-value located just beneath the part. From there, simply navigate to the Wireframe tab and launch the Curve One Edge function.
With a single click, selected model edges are converted into wireframe entities. Because the construction plane is positioned below the part, the resulting wireframe is projected directly onto that plane, creating ideal profiles for fixture design.
Even better, the function is entirely dynamic. If you select geometry by mistake (or simply change your mind) clicking the entities again instantly removes them. No cleanup is required.
Smart Selection with AutoCursor
One of the most powerful aspects of Curve on Edge is how seamlessly it works with AutoCursor settings.
By enabling only Edge Selection, users can:
- Select individual edges one at a time
- Hold the Shift key and select an edge to automatically capture all tangent edges
- Quickly refine selections without complicated workflows
Need to remove a selected entity? Simply select it again.
This dynamic behavior keeps the workflow fluid and efficient, allowing users to experiment freely without fear of creating unnecessary geometry.
Capture Entire Loops and Faces Effortlessly
Curve One Edge goes beyond individual edge selection.
When Loop Selection is enabled, users can instantly create wireframe geometry from any closed loop that exists on the model. This is especially useful when creating fixture boundaries, pocket outlines, or reference geometry.
Switching to Face Selection expands the functionality even further. Selecting a face automatically generates wireframe geometry for every edge that defines that face.
These options dramatically reduce the number of picks required and make extracting complex geometry remarkably fast.
Dynamic and Flexible by Design
One of the standout features of Curve One Edge is its flexibility.
The system intelligently recognizes various combinations of:
- Edge selections
- Loop selections
- Face selections
Users can freely mix selection methods within the same operation while dynamically adding or removing entities as needed.
Additionally, the function supports both 2D and 3D construction modes, giving programmers and designers the freedom to generate geometry exactly where and how they need it.
More Than Just Fixture Creation
While fixture design is a common application, Curve One Edge extends far beyond creating fixture profiles.
The tool is equally valuable for:
- Generating toolpath control geometry
- Creating construction wireframes
- Building reference curves
- Preparing support structures
- Developing mounting features
- Streamlining model modifications
Because the function supports solids, surfaces, and mesh entities, it integrates seamlessly into a wide range of manufacturing and design workflows.
A Tool You Will Use Again and Again
The best tools are often the simplest, and Curve One Edge is a perfect example. Its intuitive selection methods, dynamic editing capabilities, and broad geometry support make it an indispensable feature for anyone working with manufacturing models.
When you need to create additional geometry quickly and accurately, Curve One Edge eliminates unnecessary steps and keeps your workflow moving.
Whether you are building fixtures, defining toolpaths, or creating construction geometry, it should be one of the first tools you reach for.
Pro Tip: Before starting a Curve One Edge operation, customize your AutoCursor settings to match your intended workflow. Limiting available selection types can dramatically speed up geometry creation and improve selection accuracy.
