Create pipes
You now have to create the first pipe in the model. For them to end up in the “right” place in geographical terms, we will load a map as our background in the graphic window. Background maps may be in DXF or DWG format. Background maps can be straightforward basic maps, but they can also be pipe maps. The important thing is to ensure that the scaling is correct. In NetSim, one drawing unit is interpreted as meaning 1 m. Retrieve your background map by selecting File→ Input background in the menu. When your map has been loaded, select Zoom boundaries in the right-click menu.
Find the right place on the map using Zoom windod
from the right-click menu. You can also scroll using the roller on the mouse to
zoom in. This may be easier sometimes.
It may be wise to purge the background map to remove unnecessary information before loading it into NetSim.
