Numeric units in translated DWG data

Note on opening DWG files

If you do not require AutoCAD objects translated into Autodesk Inventor objects, you can directly open any AutoCAD DWG file in Autodesk Inventor. You can then view, plot, and measure the file contents. Objects display exactly as they do in AutoCAD. In addition, all the AutoCAD data is selectable for copy and paste. You can open an AutoCAD DWG file in Autodesk Inventor, and then copy and paste AutoCAD entities into any Autodesk Inventor sketch.

Since AutoCAD and Autodesk Inventor have different options for numeric formats, some attributes are converted when dimensions are translated.

Unit styles

Autodesk Inventor provides a decimal and a fractional unit style. Scientific, decimal, engineering, and Windows Desktop styles are mapped to Autodesk Inventor decimal style. Fraction and architectural are mapped to Autodesk Inventor fractional style.

Rounding precision

The greatest level of rounding precision in Autodesk Inventor is 1/128. All AutoCAD data with greater precision is converted to 1/128, and a warning message is displayed.

Decimal precision

If the precision of translated dimensions is greater than available in Autodesk Inventor, the dimensions are converted to the maximum allowed precision, and a warning message is displayed.

Zero suppression

Autodesk Inventor has a single setting for leading and trailing zeros in linear and angular dimensions. If settings in the translated dimensions are different, Autodesk Inventor uses the setting for linear dimensions.

Decimal separator

If translated dimensions use a space as the decimal separator, the space is changed to a decimal point.
