Convert Polyface Meshes and regular Meshes to 3D Solids. Connecting of meshes and commands for exploding the mesh on the line.

General Usage Instructions


Command to explode Polyface Meshes and regular Meshes on lines. The usual _Explode command does not work with PolyfaceMesh. You can also explore ordinary meshes and 3D-Face objects. You can select and detonate many meshes at once. 
Meshes can be selected before calling the command or after. 
Mesh properties (layer, color ...) are transferred to the lines.
Meshes with more than 10,000 faces are not processed, which can obscure Autodesk® AutoCAD®.


The command of converting Polyface Meshes, regular Meshes (SubDMesh object), and 'Body'-objects to 3D-Solids. AutoCAD has a built-in ConvToSolid command, but it rarely works with Meshes and never works with Polyface Meshes. A>V>C> MeshToSolid command works much more often and faster, but also not always. 

To convert a mesh to a solid, you need the mesh to completely enclose the volume, without holes or breaks.

All Polyface meshes are immediately converted to Mesh, even if they cannot be converted to solid.

If many meshes are selected at once and some of them are not closed, then the program will try to combine these meshes into one and convert them into a solid.

You can select and transform multiple meshes at once. In this case, unsuccessful meshes (failed to make solid) will be colored red.

The number of received solids is displayed on the command line.

Meshes with more than 10,000 faces are not processed as this can obscure AutoCAD. But this figure can be adjusted.

Optimization of the number of solid faces in this program is disabled by default. Therefore, rectangular faces will be composed of multiple triangles. You can enable optimization in the settings, but with optimization enabled the conversion often does not work. There have been cases where conversion with optimization has caused AutoCAD fatal errors.

The program can save the color and material of the meshes and their individual polygons and apply them to the solid faces. Finding face matches is a time-consuming process, so this feature is disabled by default.

Additional Information

Setting up

To configure the program, open the AVC Settings Palette using the AVСOptions command and select the Mesh To Solid tab.

  • Acceptable mesh complexity - The number of polygons in the mesh, more than the mesh will not be processed in AVC commands. The setting works in the MeshToSilid, MeshExplode, and Flat commands. Too complex meshes will take hours to process, and the solids obtained from them are not suitable for further work. You can assign 0 so that all meshes are processed (and kill AutoCAD). Remember that you are working in a solid modeling program and it cannot handle the crazy meshes from the Internet and from 3DS Max.

  • Saving Face Materials - Find polygons on the mesh with your own color or material and try to assign these materials to solid faces. Finding matches between mesh polygons and solid faces is a very complex and time-consuming procedure. Therefore, enable this option only if you actually assign colors and materials to some polygons.

Optimize solids - Glue mesh polygons into one solid plane to simplify the solid structure. Without optimization, the NC Preparation program will not be able to correctly construct the contours of the part for CNC. But by default, the option is disabled, because when optimization is enabled, AutoCAD often refuses to convert the mesh to solid. And there have been cases of AutoCAD crashing fatally.
