Curve fitting can be applied to strings via the style sets in the setting below.
This will graphically add curve fitting to a string when displayed with that setting enabled. The image below is a string displayed with no curve fitting enable in the style set.
The string displays as below when curve fitting is enabled in the style set.
This method is a very quick way to visually add curve fitting to MX string displayed using a style set, however it does have a downside due to no additional points being added to the strings exports to other CAD formats (I.e DXF,DWG) will show the string in it's original form as in the first image.
Curve Fitting can be applied directly to the strings which will add additional points as required and will create the desired export to other CAD formats.
