Making long roadmesh runtime

[migeg]

in my case sometimes i want to destroy road before i save it to scene. CreateMesh.Clear() is working fine. no errors

here is the error that popped up sometimes when i deleted the road under Create Mesh object:
InvalidOperationException: [Curvy] Could not create managed resource of type 'Mesh'. In some cases this is due to not enough elements in a resources Pool
