Acad 2D drawing Import to Solidworks with units default to Millimeters

[Grant]

Always been a problem for me. If you want the Import box to say mm instead of Inches in Solidworks.
This is really strange:
In Autocad type 'DDIM' (for the 'Dimension Style Manager') in the command line - click your current dimension style in the 'Styles' list so it is highlighted. Click the 'Modify' button. Click the 'Alternate Units' Tab.
Now:
Click the tick box for 'Display alternate units' to turn it on
under 'Multiplier for Alt Units' make it:
25.4 for Inches
1.0 for Centimeters
0.1 for Millimeters

Now Click the tick box for 'Display alternate units' to turn it off
Now click OK button.

Seems a strange place to take the variable from as it has no relievence to units as I had my units set to mm from the start.
If you are having this problem - give it a go! Easier than writing a macro in solidworks as I have done that as well!

Have you tried the -DWGUNITS command?
Include the hyphen.

Nothing to do with -DWGUNITS
Solidworks goes off the variable in Alternate Units for Dimensions in Acad
'Dimaltf' is the variable name!
