AUTOTUBE software dedicated to heating piping design - compatible with AutoCAD Bricscad and ZWCAD Example of a heating pipework plan drafted with AUTOTUBE

Preference Settings

Automatic loading of preferences from the DWG file.
(When opening a DWG file, the relevant preference file automatically loads up. It includes the latest modifications).
Working unit.
Drafting scale.
Layer management:
    By specialty, by geographical location and by single-line or double-line drawing mode (very flexible).
    By type of graphic entity (network, materials...).
    Several types of layer combinations (time saving).
Graphic variables for representation of:
    The appearance of ducts.
    Texts, dimensions, arrows, conduits intersections.
A range of hatching styles to symbolise coverings (thermo isolation, flocking).
Computation variables:
    Conversion of rectangular/circular sections, coefficient of roughness of materials.
    Flow units, pressure drops units.
Sets the TP scales and handles switching between model space and paper space automatically (can be switched on or off.)

Management of drawing backgrounds

Colour of entities.
Colour of layers.
Resetting the Z coordinate.
Option to isolate texts, hatches, dimensions...
Text fonts handling.
Option for renaming layers for intelligent sorting.
Management of the unit system (Metric/Imperial).
Line thickness and TP scale management...


Point to point pipe routing in single-line or double-line mode according to the material specifications.
Standard specifications for heating and air conditioning.
Five specifications specially developed for steel, copper and PVC pipework.
19 pipework specifications available for filling according to your needs.
Point to point single-line routing of a set of pipes (up to 6 pipes).
Cross-sectional drawing and computation of the distance between the centres within the set of pipes.
Automatic insertion of the list of conduits constituting a set of pipes.
Detailed drawing of all the accessories according to their configuration.
Insertion of water fittings in line.
Insertion of water fittings onto drafted pipes.
Library of standard components.
Customization of air conditioning terminals (fan coil, cassette, air handling unit...).
Drawings of the different types of heaters (panel-type radiators, multiple elements radiators...).
Symbolic or realistic representation of the heaters.
Insertion of assigned tags (descriptive tags) to the heaters.

Quick Modification Tools

Changing an object (turning an elbow into a slope, changing the ND of an already drawn duct, changing a topside connection into an underside connection...).
Moving an object (when drawing a reduction the conduits adjust and adjacent elbows follow automatically...).
Deleting an object (the conduit 'closes' automatically on deleting a connection...).


Automatic drawing and positioning of flow direction arrows.
Automatic adjustment of arrow directions.


Other Features

Show crossed networks in double-line or single-line (by hiding or ‘cutting’ with an offset of one duct in relation to another, with only 2 mouse clicks).
Automatic rebuild of sectioned conduits.
Manipulation of layers (freeze, transfer, lock, etc...).
Dimensioning settings (unit, number of decimals, arrows, etc...).
Simpler dimensioning operations than with AutoCAD. Automatic update of dimensions on changing the settings.
Proportionality factor.
Thickness management. Type of lines with inserted letter.


Single-line or multi-line texts.
Automatic update of the number of lines.
'Click to text' function: when clicking onto a network, some related data automatically pre-populate the text field (such as the air duct portion).
Automatic insertion of prefixes and suffixes in the texts.
Automatic section formatting according to the material specifications.
Automatic insertion of leader lines, frames, arrows, points, etc.
Automatic adjustment of the leader line and frame when the text is modified.
Choice of the character font and of its size.
Automatic scaling.


Definition of plan zones for the network and material bills creation. Immediate and automatic extraction of conduits and material quantities within the predefined zones.
Immediate and automatic extraction of equipment quantities within the predefined zones.
Material bills exportation to AUTOCAD or EXCEL.
Automatic insertion and management of assigned blocks.


Drawing of openings in slabs or in walls using the conduits' drawing.
Drawing of openings in slabs or in walls without using the conduits’ drawing.
Choose the shape of the openings.
Automatic dimensioning of openings.
Automatic location and tagging of markers.
Update of an opening drawing on changing its assigned tag.
Extraction of openings list and export to AUTOCAD or EXCEL.

Page Layout

Automatic drawing page layout with creation of presentations.
Automatic insertion of formats and title blocks.
Create detailed views.
Calculate the scales and update the scale of views.
Automatic insertion in the margin of the file name, of its path and of its associated XREF.


Sizing and Altimetry
Computation of a duct section according to the flow (or power and Delta T), in relation with speed constraints or pressure drops limitations.
Computation of the coefficient of friction (j) of a duct section.
Computation of a network size according to its representation.
Computation of levels while routing on changing of duct portion.
