Does your model editor supply also the ID to put in the Vertices[ID]
to retrieve the vertex coords ?
May you tell me what application are you using ?

Nobody understood your explanation
You quoted my answer to Ventilator but the working solution proposed by Ventilator it is not what you said
I suppose that also Ventilator assumed that from a generic modeller you can get the local coords only
To find the ID's you must write, as he said, some lines of codes

btw I am still using version 2.6 because 3.0 has been reported to be buggy
My version does not have a built in model editor while 3.0 has
If in version 3.0 you get also the ID , fine the problem is over
