While they are the same file format, they have different extensions. Is there a difference between STEP and STP files? STEP files maintain accuracy and compatibility across teams and workflow, from design and development to production. Details saved in STEP files include descriptions of surfaces, trim curves, topology, and some color information. STP files read and save the whole 3D model body, including geometries and surfaces, so users can edit files in programs (other than those that created the file) and still retain resolution. Each program varies in how it interprets files, and diagnostic tools help to repair topology and geometry issues. For example, engineers may use one program for designing large objects and assemblies, but teams use another program to separate designs into parts or subassemblies for machining. STEP files exchange mechanical and architectural designs for real objects between different CAD software tools. STEP CAD models can represent complex geometries, making them well-suited to replicating physical objects in manufacturing processes. Use STEP files for 3D modeling and printing.ĭesigners and manufacturers use CAD to design and create objects such as machinery or parts, buildings, or other items. STEP files, also called STP files, are easy to share because users can open, view, and edit them in an assortment of (CAD) and computer-aided manufacturing (CAM) programs. We’ll cover why people use STEP files frequently and which programs you use to open, view, and convert STEP files.Ī STEP file is a commonly used standard computer-aided design (CAD) file format. Tags: 3d.We draw on our deep knowledge and experience in helping manufacturers with 3D files to explain the advantages and disadvantages of STEP files. This is the likely scenario if you’re seeking to recreate a static part you found as a nice adjustable parametric model. Now you can edit it! Or, depending on the quality of the conversion, you may just want to use the imported model as a reference for a fresh sketch. Select the new part studio tab to view the imported model: After another moment, a second new tab will appear, this one marked with a regular part studio icon: Accept the default import processing options (or whatever):Īfter a moment of uploading, a new tab representing the raw extruder-plate.stp file will appear. Select Import:įind the STEP file previously exported from FreeCAD. OnshapeĬlick the “+” icon in the bottom left of your Onshape document to add a new tab. Select STEP format from the file type menu in the save dialog and accept the default tolerance if prompted: Go to the Part menu again and select Export CAD: Go to the Part menu and select Create shape from mesh:Īnother instance of the model will appear in the part list, with a wireframe highlight. Some details should appear in the lower left: Select the mesh by clicking it in the list on the left side of the window. Next, go to the File menu and select Open:įind your STL file and open it. Go to the View menu and select a Part workbench: I don’t know jack about FreeCAD, a cross-platform desktop CAD system, but it can be used to convert STL files to another format ( STEP) that can be successfully imported into Onshape. (Technically, it can indeed import any file type, but only for storage only select formats can be converted to an editable part studio.) It can import designs from various CAD formats, but it cannot import the ubiquitous STL format popular in the 3D printing world. Onshape is a sweet new parametric CAD system that runs in your browser. Import STL Models to Onshape Part Studios using FreeCAD
