I need to plot something that has nodes Numbers and Coordinates as in the attached file: Data_Coord.txt
the file has four columns and they correspond to: NodeNumber CoordX CoordY CoordZ, respectively
The conectivity between nodes is given by the file Data_Conec.txt
the file has three columns and they correspond to: ElementNumber Node1 Node2, respectively
Note that the number of the nodes is not sequential up to the total number of nodes, meaning that, for example, I could have node 1 conected to node 10001, even though I only have 200 nodes. but the coordinate of node 1 and 10001 is given on the Data_Coord.txt file and the first column specifies the number of the node.
How can I plot this 3D sketch?
I tried using digraph but because of the node numbers I wasnt sure how to proceed
