Import AutoCAD .dxf drawing of truck equipment to calculate axle weights for work truck

Import your own equipment

780 290 TruckScience

Now, if a component you require is not in the library, you can import a DXF drawing, and the equipment or load item will be saved in your library, to be dropped into future calculations.

Many of our Axle Weight Calculator users had been asking to import their own DXF drawings, to add equipment such as cranes, lift gates, hoists, tool boxes, APUs (Auxiliary Power Units), etc. to their library.

Importing your own equipment

Now you can simply import a drawing in a DXF file, then specify its dimensions, weight, center of gravity and position.

You’ll find the ‘Import a DXF file’ link below the library list when adding Equipment or Load to your calculation.


Next, simply select the location of the DXF file on your computer.

  • If you have existing models saved in DXF format, you can upload them straight away.
  • If you have them saved in DWG format, just re-open them and save as DXF before uploading.
  • Or if you don’t yet have a drawing for the body or equipment you need, create the drawing in Autodesk or SolidWorks or a similar program, save to DXF and then upload it.

If necessary, move the bottom or mounting point of the item to the origin, that is where (x,y) = (0,0).

Override Length or Height, if necessary.  The ratio of these is locked so that your drawing will not be distorted.  Then specify Width.

Specify the Weight of your item, and override the default values for Horizontal (Front to Back), Vertical (Bottom to Top) and Lateral (Left to Right) Center of Gravity.

Specify the name by which your item will be identified on your drawing, and saved to your library.

And in this case, the crane is added to your calculation, with dimensions and weights as specified.

More Regulations for users in Australia

According to the National Heavy Vehicle Regulator website in Australia, Concessional Mass Limits (CML) allow an operator to operate at mass limits above the national general limits provided the operator is accredited under the National Heavy Vehicle Accreditation Scheme (NHVAS).  And Higher Mass Limits (HML) provide a significant increase in the productivity of road freight transport vehicles.  Now you can specify the particular Mass Limits that apply to your configuration – General (GML), CML or HML – and choose between National or State (Western Australia or Victoria) regulations, in the Settings area.
