AUTOGAINE: software for draftsmen and engineers specialised in air-conditioning and ventilation networks plan design Example of aeraulic networks drafted wit hAUTOGAINE

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
    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 air duct routing in single-line or double-line mode
Detailed drawings of all the accessories according to their configuration
Automatic insertion of components
Library of standard components
Customization of air conditioning terminals (fan coil, cassette, air handling unit...)
Drawing of grids and registers
Automatic adjustment of grids and diffusers onto suspended ceilings
Registers library to draft grids and plenums
Automatic drawing of register connections onto main sewer pipes
Detailed drawing of flexible conduits with customizable curve radius

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 airflow (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
