When working with 3D models, STL (STereoLithography) files are commonly used for their ability to represent the surface geometry of objects. However, sometimes you might need to edit these files to modify designs, fix errors, or adjust dimensions. While some professional CAD software offers robust editing capabilities, not everyone has access to such tools or prefers the learning curve associated with them. Fortunately, there are several online platforms that allow you to edit STL files directly from your browser, making the process more accessible and convenient. In this guide, we'll explore some popular online STL editors and discuss their features, benefits, and limitations.
1. MeshLab

Features:
Editing Tools: Allows for vertex, edge, and face editing.
Mesh Repair: Tools for fixing holes, removing duplicate vertices, and repairing cracks.
Texture Mapping: Enables applying textures to the 3D model.
Rendering: Highquality visualization options.
Pros:
Free and opensource.
Extensive community support and documentation.
Suitable for both beginners and advanced users.
Cons:
Steep learning curve due to its powerful feature set.
Requires downloading and installing software.
2. CloudCompare
Description: CloudCompare is another free, opensource tool designed for handling point clouds, but it also supports STL files. It offers a wide range of functionalities for 3D data processing and analysis.
Features:
