Short description of error
Objcet has no mesh data to be used for ray casting

example:
https://github.com/Darcvizer/Destructive-Extrude/blob/master/Destructive-Extrude.py
line 208

When I try to make a ray_cast in object mode, I get an error “Object has no mesh data to be used for ray casting” I tried to fix it by following the steps:
bpy.context.scene.update()
context.active_object.data.update()
context.active_object.data.update(calc_edges=False)
context.active_object.update_tag(refresh={‘OBJECT’, ‘DATA’, ‘TIME’})

And even:
bpy.ops.object.mode_set(mode=‘EDIT’)
bpy.ops.object.mode_set(mode=‘OBJECT’)

In Python Console:

>> C.active_object.ray_cast((0,0,0), (1,1,1))
