EpaCAD v1.0

Developed by ITA Universidad Politécnica de Valencia

www.ita.upv.es

EpaCAD allows converting AutoCAD files which contain pipes into files that can be opened with EPANET, the most popular water distribution system analysis program

PROGRAM HELP

Open Enter the AutoCAD file path. File should have .dxf extension (AutoCAD allows to save files with this extension). EpaCAD program reads files saved as dxf from AutoCAD R12/LT2/2000/LT2000/2004 and later versions.

Once the file is loaded::

1st Pipe layers selection

Select the layers which contain the pipes of model (a single or multiple selection is allowed).

2nd Conversion

Mode

Indicate the conversion mode of the polylines of the selected layers. There are two options:

• Vertex Mode: Polyline becomes a single pipe.

AutoCAD polyline EpaCAD pipe

This mode allows simplifying model, only will be characterized two nodes and one pipe. • Node Mode: Each polyline vertex is converted into a node, therefore each segment of the polyline becomes a different pipe.

AutoCAD polyline EpaCAD pipes

This modality allows introducing different properties in each node and in each segment of the polyline.

3rd Connection Tolerance

It is possible to define the tolerance with which the program considers that two contiguous pipes are connected. The default tolerance value used by de program is zero. In case another tolerance value is desired, a numerical value can be manually introduced (in meters). Consider the following examples:

• Tolerance 1: if the distance between the two nodes of the lines is closer than the defined tolerance, EpaCAD considers that both pipes are connected.

AutoCAD lines EpaCAD pipes

• Tolerance 2: in other case, EpaCAD considers that both

pipes are independent:

Once the network has been converted, EpaCAD shows a previsualization. If the previsualization is correct press FINALIZE bottom indicating the path where the .inp file must be saved later.

Another icons of the program:

Launching The program opens the last generated file in EPANET. EPANET must be installed in your computer firstly.

Update EpaCAD connects to ITA server for checking the existence of a new program version.
