## 7.12. Drawing piping system within heating zones

The graphical editor features a tool for automatic drawing of the piping system forming a heating circuit. Sometimes, however, there may be a need to draw the piping manually – when, for instance, automatic drawing does not provide expected results, or when we want the piping to be drawn only in part of a heating zone. In terms of their properties, the lines drawn, either automatically or manually, are equivalent to polylines (graphical component). Data fields and properties of polylines for drawing piping are described in section 6.2.8.

! Polylines should be entered into the drawing at the end of the process of editing the project, when calculation results are complete. Otherwise any change in calculations may make the polylines on the drawing invalid and necessitate editing them.
