更多信息什么是 STP 文件？
STEP （或 STP）是一种流行的文件格式，用于存储和传输三维和二维几何模型、零件和设计数据。
它是一种广泛使用的文件格式，由流行的计算机辅助制造（CAM）和计算机辅助设计（CAD）软件支持。STP 文件具有高保真和互操作性，可简化设计工作流程。

STP文件的用途是什么？
STP CAD文件最常用于在CAD和CAM程序之间传输三维数据，许多公司使用STP文件来设计和创建定价模型以及制造零件。
哪些程序可以打开STP文件？
打开STP文件需要支持STEP文件格式的3D建模软件或STP查看器。以下是一些常用的可以打开STP文件的软件：
- Autodesk Fusion 360
- Dassault Systemes CATIA
- Dassault Systemes SolidWorks
- Siemens Solid Edge
- IMSI TurboCAD
- Kubotek KeyCreator
- FreeCAD
- ABViewer
- ShareCAD
- eMachineShop
如何在程序中打开STP文件？
要打开或查看STP文件的内容，需要将其导入到能够读取并将该文件转换为本地格式的程序中。
请注意，每个应用程序可能有所不同，您应查阅开发者的网站以获取打开.stp文件的说明。点击这里查看如何在AutoCAD中查看STP文件的说明。
下面介绍如何读取STP文件、导入和导出文件，以及无论您的程序是否原生支持STP扩展名，都可以查看.stp文件的最简便方法。
什么是STP文件？（以及STP文件扩展名的含义）
STEP代表“Standard for the Exchange of Product Model Data”，是一种用于CAD设计的标准化ISO文件格式。
STEP文件使用.step或.stp文件扩展名。STEP于1994年推出，旨在标准化3D CAD数据的共享，它是一种中立（非专有）的文件格式，意味着它不依赖于任何特定的CAD/CAM平台。
其出色的互操作性和向后兼容性使其非常适合在设计、开发、仿真和生产过程中使用不同应用程序的大型团队。
.STP文件扩展名包含哪些信息？
STP文件以纯文本ASCII格式存储3D建模数据、零件信息和元数据，符合STEP应用协议ISO 10303-242:2014。STP文件可以包含以下相关数据：
- 工艺规划
- 机械设计（包括几何模型、3D对象、表面数据）
- 运动学
- 复合设计
导入、导出和查看STP文件
虽然许多CAD/CAM应用程序可以打开STP文件，但在导入或导出3D模型时，用户可能会遇到元数据丢失、转换错误以及文件尺寸不理想等问题。为了实现更高效的工作流程，建议考虑使用Spatial的3D InterOp。它能够：
- 查看、使用并将STP文件转换为其他CAD/CAM文件格式
- 减小文件尺寸
- 实现本地数据转换
- 与各种CAD/CAM软件实现互操作性
- 选择性地导入数据
- 以及更多功能
