As you can see in the image, even for this simple case, the conversion is not perfect. Alibre is an inexpensive parametric modeler that included a mesh to parametric converter through the 2018 version.
Plenty of online info about repairing meshes using blender.
See the image below that shows a rectangular solid with a cylindrical hole in it in Blender and Alibre. Maybe try the blender import plugin, then use blender to repair the issues, so you can export to. Smoothing is an algorithm that uses the normals of adjacent faces to present a smoother view, effectively hiding the sharp edges between faces.Īlthough conversion from a mesh to a parametric solid (so it could be exported as a STEP file) may not be possible in general, it can be done for simple cases. By comparison, for a mesh sphere, if you zoom in far enough, the faces will be visible–if smoothing is off.
This will only work on text files that contain 3D data, not just any text files.
Such txt to obj conversion can be done with various CAD / 3D modeling programs including the free Blender.
Want to make and export 3D printable STL files with Blender Check out this simple guide to learn how to do it Contents. Convert 3D Models online for free - OBJ, STL, 3DS, Collada, DXF, LWO, MDL, MD2, MD3 (Quake) and 30 more formats supported. No matter how far you zoom in, it will always be displayed as a smooth sphere. 3D Model data saved in textual form (mainly various ASCII formats) can be usually converted to a common 3D object file (.obj). Blender & STL Files: How to Make 3D Printables. But the converter can do even more: STL files for 3D printing, OBJ files. A sphere in a parametric modeler like SolidWorks is a mathematical construct that defines its diameter. Convert BLEND files quickly and easily to OBJ files, online and completely free. A sphere in a mesh modeler like Blender is composed of many triangular polygons enclosing a spherical volume. To convert your file click the Upload button below and select the file to convert. Our free and fast tool will convert most 3D mesh or STL model files to a standard OBJ file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. As an example for a very simple case, consider a sphere. Convert Your 3D Mesh/Model STL Files to OBJ. These are composed of mathematically defined features. Search for jobs related to Convert obj files stl files or hire on the worlds largest freelancing marketplace with 19m+ jobs. By comparison, programs like SolidWorks, Creo, Inventor, etc. The meshes are infinitely thin surfaces that completely enclose the mesh object. The issue is programs like Blender, Maya, etc. STEP files are used to import/export parametric models and assemblies.
I don’t believe you will find software that can create a STEP file from a mesh for the general case.
