There are not so many stages here!
Open the calculation form, specify and name a calculation file, select Visa manuella inställningar [Display manual settings and press the Beräkna [Calculate button.
Do not start the calculation module without opening the calculation file in Anteckningar [Notes (the button at the top right).
Search for the first row starting with *NODE, delete all rows above this row and save the file. If you do this, you will retain all model headers and factors unchanged.
Close the calculation module, in NetSim open the model which you have to supplement with pipes from your interpreted drawing. In the menu, select Arkiv [File - Importera beräkningsfil [Import calculation file and highlight your file. The pipes and nodes in the file now become members of the model!
Important!
The pipes which you import must be linked in one or more cases to an existing node in the model to which you import. If you take the file as it is, you have to search for the “connection points” and select there the “new” pipe and switch the node from the node which came with the import to the node which already existed in the model at the “connection point”. There will now be a node left over in the model which has no pipes to it. You have to delete this node. Search for it in the node table and select Ta bort object [Delete object.
Of course, you can switch the node names directly in the import file, but if you do then remember that the name has to be changed both in the keyword *NODE and at the point where it occurs in the keyword *PIPE. The safest thing to do it use search/replace when you do this!
