Can a shop drawing originally done in imperial units be changed to metric. Creating a new dimension style in ACAD based on DSC_DIM_STYLE1 with the alternate units presents the correct dimensioning. However a new Style based on DSC_DIM_STYLE1 with the primary units set to display decimal units and a scale set for metric does not display correctly. For example… 2′-3 5/8″ [702mm] is displayed correctly, but a setup for just metric display shows 28. No matter what the scale is set to it always shows 28. What do I have to do to get this to show correctly.
If you change the primary units you will have to set the Dimension Style Scale Factor (DIMLFAC) on the Primary Units tab of the Dimension Style dialog to scale the units of the model / drawing to the units you want to use. So if the model / drawing was 1unit = 1 inch and you now want to dimension in millimeters 1 unit = 25.4mm so the DIMLFAC scale factor of the dimesnion style should be set to 25.4. That should do it.
