8 Best Free STL Editor Software For Windows
Here is a list of Best Free STL Editor Software For Windows. These 3D design software let you import STL files along with other 3D drawing files. Once imported, you can use various tools available in these software to edit STL files as required. Some let you apply simple modifications, while some help you out with advanced tools to make your work easy. Some of these STL editors are 3D printing software, and let you print 3D designs after you have completed your design. If you are new to this environment, you might take some time to get along with using these freeware; however, these are pretty easy to understand and operate.
A STL file or STereoLithography file is a native file format for Stereolithography. It is commonly used for 3D design and 3D printing purposes. If you are already into 3D printing, then you must be aware of these terms. A STL file is basically representation of 3D diagrams using small triangular meshes.
Well, these freeware let you open and modify STL files by editing triangular mesh, adding new mesh layer, new shapes, and much more. Other features that you will find in some of these STL editor are Repair Tool, inbuilt blocks, shape building tool, 2D to 3D development tool, etc.
All of the mentioned STD editing tools are absolutely free to use with/without some limitations. To know more about these software to edit STL files, go through the article. Each freeware has been summarized briefly. You will also know How To Edit STL Files with these software.
My Favorite STL Editor Software:
