This section lists some examples in setting up the working units and data scaling using the Translator.ini file. See Translator.ini File Options for a description of the main conversion options provided by the Translator.ini file.

No Scaling Required

If the source data is in known working units, then set up the working units to match those used in the source data.

Source Data: 1 positional unit = 1 mm
Output: 1 positional unit = 1 mm

Settings:
Master Units = 61 (mm)
Sub Units = 61 (mm)
Sub Units Per Master Units = 1
Positional Units Per Sub Unit = 1

Keep the Same Working Units But Scale Model Up

You have an AutoCAD file that was originally designed in millimeters, but Smart 3D sees all distances scaled to meters. To remedy this, you can modify the AutoCAD section in the translator.ini file as shown below:

[AutoCAD Options]
Master Units = 61
Sub Units = 61
Sub Units Per Master Units = 1
Positional Units Per Sub Unit = 1

The number 61 corresponds to millimeters. This tells Smart 3D that all AutoCAD files were originally designed in millimeters and should be converted using the same value.

Conversion Between Imperial and Metric Unit Systems

The settings below are used by Smart 3D to perform limited conversions between systems. If scaling other than the system conversion is required, adjust either the assumed source unit or adjust the Positional Units Per Sub Unit (before rounding), as appropriate.

METRIC TO IMPERIAL

Convert from metric to miles to minimize round-off error.

  • Source Data: 1 positional unit = 1 m

Settings:

Master Units = 67 (mile)
Sub Units = 67 (mile)
Sub Units Per Master Units = 1
Positional Units Per Sub Unit = 1609 (1609.344 m per mi)

Source Data: 1 positional unit = 1 mm

Settings:

Master Units = 67 (mile)

Sub Units = 67 (mile)

Sub Units Per Master Units = 1

Positional Units Per Sub Unit = 1609344 (1609344 mm per mi)

IMPERIAL TO METRIC

Convert from imperial to kilometers to minimize round-off errors.

  • Source Data: 1 positional unit = 1 ft

Settings:

Master Units = 63 (km)

Sub Units = 63 (km)

Sub Units Per Master Units = 1

Positional Units Per Sub Unit = 3281 (3280.839895 ft per km)

  • Source Data: 1 positional unit = 1 in

Settings:

Master Units = 63 (km)

Sub Units = 63 (km)

Sub Units Per Master Units = 1

Positional Units Per Sub Unit = 39370 (39370.07874 in per km)
