Dimensions

Sure i can do this:

Create one style with the bracket as prefix and suffix for the main unit mm, nothing for the secondary unit.  Create another type with main unit as imperial and secondary unit as mm.  Place three dimensions side by side, not as one string.

 This is a very strange request, as showing the window opening height next to wall length is very misleading. A person reading this will automatically assume you are asking for a 4'-0 (1219mm) wide window.

But if that is what you are asking, I can get most of the way there with three (3) superimposed copies of the same dimension with different dimension types:

1. The first string generates the alternate metric dimensions below the dimension line;
2. The second string (shown in red below) will mask out the imperial dimensions above the line  but also the line itself;
3. The third string with draw the line on top (See "RESULT WITH 3 OVERLAPPING DIMENSIONS") below.

If you don't need the opening height on your dimension strings, the result will be all dimensions strings below the line in metric units.

Hope this helps,

I assume alternate dim units with suffix/prefix as style (and without showing primary unit) only became available from Rv18...

I read somewhere people uses tiny text size for primary unit in order to "hide" it.

I'm with @lucdoucet_msdl. That use of a linear dimension to indicate window height is just plain wrong from a drafting point of view.

I suspect I am taking your screen capture too literally.

It would help when posting questions/problems to state your objective and/or some context, such as : "I want all dimensions to appear in metric below the dimension line", "I want the window opening to be in metric/imperial with the wall dimensions in metric", "My project manager wants my dimension lines to be blatantly misleading" ;-).
