AutoCAD is a leading DWG editor trusted by architects, engineers, and designers for advanced 2D and 3D modeling. But when working with legacy polyface and polygon meshes, you may notice that solid modeling tools like EXTRUDE, REVOLVE, and SWEEP are not available. To unlock full 3D modeling functionality, you need to convert polyface mesh to solid in AutoCAD.
AutoCAD Mesh Converting Capabilities
AutoCAD provides built-in tools for converting mesh models into solid geometry. These mesh-to-solid tools are accessible from the Modify panel in the 3D Modeling workspace:
- CONVTOSOLID: The CONVTOSOLID command converts a polyface mesh to a solid by automatically filling gaps between mesh faces. This is the primary method used when converting mesh to solid in AutoCAD.
- MESHSMOOTH: Although not a direct conversion tool, the MESHSMOOTH command subdivides and smooths the mesh faces. This process helps prepare high-resolution or detailed meshes for a successful solid conversion using CONVTOSOLID.
These tools work well for basic geometry, but complex or non-manifold polyface meshes often require a more advanced approach.
Convert Polyface Mesh to Solid with Automesher
For professionals who routinely work with meshes, our Automesher Application is a powerful AutoCAD add-on that extends native mesh converting capabilities. It simplifies the process of converting complex AutoCAD mesh to solid geometry, even when standard commands fail. It's key capabilities include:
- Broad Format Compatibility: Automesher supports a wide range of 3D file formats, including SKP, STEP, FBX, OBJ, DAE, and 3DM. This ensures seamless file import and export for your CAD projects.
- Advanced Mesh to Solid Conversion: Automesher handles polyface meshes with non-manifold edges, self-intersections, and gaps - converting them into clean, editable solid objects that integrate directly into your AutoCAD workflow.
Why Automesher is the Best Tool to Convert Mesh to Solid in AutoCAD
Although AutoCAD provides basic polyface mesh to solid conversion tools, they may not be reliable for detailed or error-prone models. Automesher improves your conversion success rate and supports complex geometries that native commands often fail to process. Whether you're working with architectural models, engineering components, or scanned meshes, Automesher ensures accurate and efficient conversion to solids.
CONVTOSOLID 🆚 AmConvertMesh from Automesher
Here's a quick comparison between AutoCAD’s built-in CONVTOSOLID command and Automesher’s AmConvertMesh command.
| Feature | ️ CONVTOSOLID | ️ AmConvertMesh |
|---|---|---|
| Supported Meshes | Basic watertight meshes only; fails on complex or non-manifold meshes. | ✅ Handles complex triangulated meshes, STL, OBJ, and more. |
| Repair Tools | ❌ None - clean mesh required | ✅ Auto healing, hole filling, and topology fixes |
| Limitations | 💥 Often produces errors or fails on imported mesh data. | ✅ More reliable with mesh repair tools. |
| Output | 3d solid or surface objects (if successful). | Clean solids with better edge stitching and watertightness. |
Final Thoughts: Boost Your Mesh Converting Workflow
If you frequently deal with legacy mesh models, investing in the right tools is essential. Automesher Application enhances your ability to convert mesh to solid in AutoCAD - transforming problematic polyface meshes into usable solids. It's the ideal solution for anyone seeking robust mesh converting capabilities in AutoCAD, BricsCAD, GstarCAD, or ZWCAD.
