![]() I guess that hand editing of the mesh is involved. Materialise claims to have conversion software called 3-matic but I have not tried it and they are foggy about downloading and using it. Rhino has an option to convert a mesh to real, smooth, curved NURBS surfaces. used to convert the STL file format into a NURBS (Non-Uniform Rational B-Spline) format whose surfaces could then be exported as a solid CAD model using. Not sure what software you use but you can usually simply go to save as and choose the desired extension. Yes I think those file formats are more universal so they’re used when transfering models. Mesh to Single Nurbs from Resurf converts a mesh model to one single NURBS but only for not-too-complex surfaces of course. Download a trial version of fusion 360 and import your files into the software and export the format you need. MeshLab is great open source to repair, smooth and simplify mesh models, especially from 3D scans. Some formats have a related wiki page that can be reached by clicking on the extension in the first column. For completeness the FreeCAD native format is included in the list. As the conversion blender > collada > STP works (although file size might explode) When i go the other way FreeCad STP model > collada /STL > blender I somehow endup with a lot of duplicated objects, though they can be removed manually. Introduction This page lists the various file formats that FreeCAD can import and export. Inventor has an add-in named Mesh Enabler which does the same but is limited to 5000 facets. May i sugest someone to develop STP export import. Adding wall thickness to such a model normally fails because mesh surfaces are noisy, not smooth. That's fine if you don't mind but if you want a smooth model with less surface patches this is not the way. It's completely identical in shape to the original. The end result is a model with just as many facets as the original model. Their use is for rapid prototyping and FEM analysis.FreeCAD works but the drawback is that the IGES- or STEP-model is still a facet model with flat, triangular, first degree NURBS surfaces. This video explains how to convert a STL file to Step or editable 3dmodel file format using FreeCAD Software : FreeCAD 0.18 Show more FreeCAD 0.19 - Converting STL files to Solid models. 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. As both the IGES/IGS and STP/STEP are fairly common CAD formats used for exchange purposes, so it should be fairly easy to find a program that can convert one to another. We have found 17 software records in our database eligible for. While the new object is selected, select Part -> Convert to solid menu, a third object is created. Convert IGES 3D exchange format to ISO-10303 STEP product data.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. ![]()
