Using freecad to convert iges to stp8/9/2023 For Linux users: External IfcOpenShell module required. External IFCJson module required (must be installed manually). Industry Foundation Classes exchange format for BIM models. Open CAD format (obsolete, 2D-only format) External software required for the legacy Python importer and the legacy Python exporter. The Save As option will force the user to use a FreeCAD file format. It is recommended to use Export instead of Save As. Once complete, the file is ready for all uses. With the solid part selected in the workspace, click File > Export and choose the STEP format from the options. External software required.Īutodesk drawing exchange format. Export Your Solid Formation Into a STEP File. For Linux users: External p圜ollada module required.ĪutoCAD native format. OpenSCAD Constructive Solid Geometry formatĬollada format. See the following pages for additional information:ĪSCII Stereolithography mesh (mostly used for 3D printing) You need to open the Part view first: Then click on the filename in the left panel to select it (or use Control-A to Select All). Some formats have a related wiki page that can be reached by clicking on the extension in the first column. I think you’re missing the steps to convert the imported STL mesh to a FreeCAD shape. For completeness the FreeCAD native format is included in the list. Their use is for rapid prototyping and FEM analysis.This page lists the various file formats that FreeCAD can import and export. As a rule, mesh formats are unsuited for CAD. To quote Wikipedia, polygonal modeling is an approach for modeling objects by representing or approximating their surfaces using polygons. If unsure, choose the first one.īut you need to know that STL is a mesh format, like those done with a polygonal modeller (SketchUp is a polygonal modeller). stp extension and click OK in the dialog, either select "CAD formats (PART)" or STEP 214 (Import). Select the solid object, go to File -> Export., enter a name with.You now have a solid that can be exported to STEP. 1 Introduction 2 Notes 2.1 TechDraw pages 2.2 OpenSCAD files 3 Related 4 Available preferences 4.1 DAE 4.2 DWG 4.3 DXF 4.4 IGES 4.5 IFC 4.5.1 IFC import 4.5.2 IFC export 4.6 INP 4.7 IPT 4.8 Mesh Formats 4.9 OCA 4.10 STEP 4.11 SVG 4.12 VTK Introduction FreeCAD can import and export many file formats. While the new object is selected, select Part -> Convert to solid menu, a third object is created.A new object is created, hide the original one (click on it and hit space bar) menu, in the dialog select a tolerance for sewing, click OK. Select Part -> Create Shape from mesh.Click on the mesh object, either on the 3D screen or in the Project tree.This means that they are pretty much always supported in any 3D modeling / CAD software and it should not be hard to achieve iges to stp conversion or export. Switch to the Part workbench (View -> Workbench menu) Both the IGES/IGS and STP/STEP are common CAD formats, which are used used for exchange purposes.Once you've installed FreeCAD, you can open your STL or OBJ file and convert it to solid, to export as STEP or IGES: What I've learned is CNC cutting is very different paradigm from rapid prototyping, which polygons and STL format works well with.ĭownload and install free, FreeCAD (procedure taken from NormandC on the FreeCad Forum) The truly best way would be to model on Nurbs from the start, although not so common to us in the animation biz anymore. Although I think that Sabastian's solution is the best, although I haven't heard back from the Guy with the Solidworks yet. įreeCad works to convert OBJ or STL to STEP or IGES, see below. Besides converting to the poly mesh to nurbs, I also found that. import cadquery as cq afile cq.importers.importStep filename. It can open step files and easily export them in a couple lines of code. I think I understand the situation pretty well now. 1 Answer Sorted by: 1 I would suggest checking out cadquery.
