How to convert 3dsolid to subdmesh?

[Anonymous]

Hello,i'm new here,i found a post here ask about get mesh data.

https://forums.autodesk.com/t5/objectarx/how-to-get-mesh-data/td-p/8190607

I tried to export mesh data to Unity too ,but i don't know how to convert 3dsolid to subdmesh.

I only see AcDb3dSolid::createFrom and AcDbSubDMesh::convertToSolid,both convert subdmesh to 3dsolid.

It's my first time to use arx,anyway,thanks.

I see such way: AcDb3dSolid -> AcDbPolyFaceMesh -> AcDbSubDMesh

1. AcDb3dSolid -> AcDbPolyFaceMesh: http://adn-cis.org/forum/index.php?topic=6998.msg19405#msg19405

2. AcDbPolyFaceMesh -> AcDbSubDMesh: https://adndevblog.typepad.com/autocad/2016/11/how-to-convert-polyfacemesh-to-3dsolid.html  (only GetPolyFaceMeshData and CreateSubdMesh functions)

Other way is using acdbGetObjectMesh function: https://adndevblog.typepad.com/autocad/2012/05/define-holes-with-acddsubdmeshsetsubdmesh-the-same-way-as-with-acgigeometryshell.html
