STEP(ISO 10303-21)是通用的CAD交换格式——从Fusion 360到SolidWorks再到NX,几乎所有机械设计工具都支持。但打开它通常意味着安装庞大的CAD软件、注册云查看器,或将设计上传到陌生人的服务器。MakerSuite 3D采用不同的方法:STEP解析器在您的浏览器标签页中运行,由编译为WebAssembly的OpenCascade驱动。拖放.step或.stp文件,几秒内即可看到装配体——无需安装、无需账号、无需上传。
MakerSuite 3D支持三种主流STEP应用协议——AP203(配置管理3D设计)、AP214(汽车)、AP242(AP203+AP214合并加PMI)。嵌套零件、变换和每面颜色的装配体都会保留。结果是完全可导航的Three.js场景,支持轨道、缩放、剖切和测量。
Drop a .step or .stp file — see your CAD model in seconds.
Try MakerSuite 3D FreeSTEP文件是硬件设计的通用语——供应商发送、客户请求、开源硬件项目发布。但每个相关方不应该为了打开一个文件就需要2000美元的CAD许可证。浏览器查看器让采购团队检查供应商机械结构、电气工程师验证外壳适配、采购方验证样品——全部无需安装软件。而且因为解析在本地进行,公司可以分享STEP文件而不用担心云上传的NDA违规风险。
STEP文件完全在您的浏览器标签页中解析。无上传、无服务器往返、无账号。关闭标签页即无痕迹。同样适用于查看器支持的所有格式——STL、OBJ、GLB、FBX、3MF等。
No. MakerSuite 3D parses STEP files entirely in your browser using occt-import-js (OpenCascade compiled to WebAssembly). You get a full 3D preview — assemblies, colors, and geometry — without installing any CAD software or creating an account.
AP203, AP214, and AP242 — the three dominant STEP protocols for mechanical CAD. Both .step and .stp extensions work. The parser handles assemblies with nested parts and transforms them into a Three.js scene graph you can orbit, zoom, and measure.
Yes. Click the Measure tool, then click two points on the model to get a distance readout in mm or inches. The measurement list persists in the sidebar so you can capture multiple dimensions without losing previous ones.
STEP files up to ~200 MB parse in most modern browsers. For anything larger, the first-load time can exceed 30 seconds — we show a progress toast so you know it's still working. If your assembly is 500 MB+, consider splitting it before upload.
No. Parsing happens entirely in your browser tab. The STEP file never leaves your machine, there's no server round-trip, and no account is needed. Close the tab and there's no trace.
