Mesh Objects imported with FileLoader node are unable to edit, Why?


I can import var type of Mesh files with [FileLoader.FromParh] node (include FBX, SKP)

But, Mesh Objects imported with File Loader node are unable to edit.
For example, When I transform or scale the mesh objects with MeshToolkit, It is no t working. The same is true for other nodes of MeshToolkit.

Why? Are there any methods to edit the mesh objects?
I konw it has no mater to obj, stl files imported with [Mesh.ImportFile] node of MeshToolkit.
I am studying about scalability of Import node like FileLoader to import various files to dynamo form other programs.

Thank you for your comment!

These nodes likely return Dynamo Mesh objects, which are not the same as meshtoolkit meshes - I think theres a conversion snippet floating around somewhere - perhaps in the springs package.


Thank you so much for your comment is very helpful for me.
It has “Mesh.ToToolkitMesh” and “ToollkitMeshToMesh” as you said. :slight_smile:

The function “Online Package Search” on my Dynamo Studio ( didn’t work for some reason I don’t know, so I could found out “Springs” Pkg on the Dynamostudio Website (

Thank you, @Michael_Kirschner2 Michael!

likely you need to update your revit version - ADSK has updated to more recent TLS protocols for services.
