ON_Mesh* "Append" time

HI All:
I use ON_Mesh* to save the ON_Mesh.When I update my project from R5 to R6, I found out that the time I spent which increased hundred times, so I gave it a try, The results of the try , the time R6 spent which is hundred times greater than R5. I gave it another try, I found out the more quantity in the container, the more time it takes for Append to have the same number of grids. I’m wondering if it would be possible to know did ‘’Append function’’ change?

Hi @minbear,

For bulk mesh appending, use ON_Mesh::Append(int count, const ON_Mesh* const* meshes).
