Explode polyface mesh to 3D face

Recommended Posts

Hi guys,

 

I need help!

 

How can I EXPLODE a polyface MESH to 3D Face BUT keep original colors. I would appreciate it if you help me to solve the problem. DWG file attached.

 

Kind Regards,

As Far As I know :

 

It can be done, but not with AutoCAD's standard tools.

 

I don't know what program created the mesh and or converted into AutoCAD's PFace format, but I do know it

used many non standard values.

 

Is true color a must or can ACAD's ACI be suffecient ?

It was created by voxler. I contacted them but nothing for now.

 

Actually, doesn't matter which type of color it should be. All I want is to see same color in both voxler and autocad.

In Autolisp, you can extract the layer or color data and create a new faces based on the mesh data:

 

 

I know next to nothing about RGB colr, so this uses AutoCAD ACI Colors.

 

The moderators may move this thread to the the autolisp section of the forum.

You will need to run this on each PFACE mesh in the drawing ( your sample has (2) meshes )

 

 

There is a tutorial on how to load an AutoLISP routine on the site.

 

Somehow you meshes referenced a face index number of 0. In the past, all face indexes started with number 1.

Thank you for your assistance. I have already handled issue with standard AutoCAD tools.

 

I created mesh from polyface mesh by using "Mesh Tessellation Options". It seemed to ignore all the colors but after exploding it all the original colors came back and perfect 3D face object as a result.
