The Heating-cooling surface component (floors and ceilings) can be appended with drawings of loops. Drawings generated automatically by the program are refreshed each time the project is recalculated. It is possible to modify or append them and loops can be drawn manually. Manual editing is recommended at the final stage of design.

Location in the program

  • General data - automatic generation of loops can be enabled for all components by selecting the Generate loops drawings checkbox.
    1. Loops drawings - General data

  • Data table for component Heating/Cooling Floor Zone, when working in the Rad.-floors,walls/Rad.-ceilings editing range, enables:
    • automatic generation of loops by selecting the Generate loops drawings checkbox; loop generation can be disabled here for a selected component when this checkbox is selected in General data,
    • selection of pipe laying pattern.
      2. Pipe laying pattern

  • The RHC loop tool available in Main tools, when working in the Loop drawings-floor/Loop drawings-ceiling editing range, enables manual drawing of loops. Use of this tool is recommended with the GRID mode enabled.
    3.Loop drawings - Graphical editing

Example of use

Automatic generation of loop drawings

  1. Enable generation of loop drawings in general data or for selected components.
  2. Calculate the project Loops-calculation.png. Upon calculating the project, loop drawings will be generated automatically.
  3. Change direction of loop arrangement (option).
    After selecting Heating-cooling surface hotpoints of loop laying direction become available Direction.png, and in the case of Single pipe meander pattern/Double pipe meander pattern a pointer is also available Side.png for indicating the side along which meandering is to be done. To display the effect of changing the loop laying direction and of indicating other side, the file must be recalculated.

Manual editing of loop drawings

  1. Disable generation of loop drawings for selected components Heating-cooling surface.
    Attention! Clearing the Generate loops drawings option does not remove existing drawings of loops, it only freezes them in their current state and enables manual editing or deleting thereof. To completely remove loop drawings double left click the loop and select Delete selected components.
  2. Enable the GRID mode which helps in correcting or manual drawing of loops. Grid nodes are arranged at the minimum distance allowable for the selected pipe laying pattern. Colours of grid nodes are repeated for the current pipe spacing, which facilitates drawing with the use of that spacing. The grid can be arranged parallel to selected edge of component Heating/Cooling Floor Zone by positioning on that edge the blue hot-point Hot-point-obrot.png. It becomes available when component Heating/Cooling Floor Zone is selected.
  3. Correct/draw manually selected segments of loop.
  4. The loop drawn must be contained completely within the Heating/cooling surface component and must terminate at its edge.

Manual editing of loop drawings in dry systems with guide plates

  1. Manual editing of loops is the only way for designing correct loops in systems based on Dry system plate type components .
  2. In the case of dry floor systems with Dry system plate catalog components arranged in the program, the characteristic points of the plates take on the role of a grid.
  3. In dry systems with Dry system plate the use of the "drawing loop length" function is recommended.

Additional information

  • Graphic style - in order to improve the legibility of loop printouts, one can:
    • select manner of loop display where loops differ in colour and pipe feeds are of the same colour as the corresponding loops
      4. Component styles - no colour difference between loops

      5. Graphical editing - no colour difference between loops

      6. Component styles - loops differ in colour

      7. Graphical editing - loops differ in colour

  • Loop drawings are not mandatory and they do not have to be complete if the "drawing loop length" option has not been selected.
  • In the case of virtual connections, automatically generated loops originate from arbitrary points indicated by the program. After pipe feeds are drawn, the starting points of loops are automatically relocated. The loop drawings can also be automatically modified due to the routes of pipe feeds to other areas/rooms being taken into account.
