I have just changed the default WM-Marker to fit my needs
In my work i only want the Height and Width of a door/window.
The dimension usually are in a circle separated by a line (a diameter of the circle)
So i made WD-marker to do exactly this for me ,so i don't have every time to change the Marker position the extension line etc.
Of course my marker is not perfect
So i don't know what happens if you change the scale of your plan (other than 1:50) or the Marker type from circle to triangle
You can not display any other infos than W/D height /width The size of the marker is always 5 times bigger than the text size (no matter what you enter in the field "Marker Size") BUT you can change the position of the marker (circle/extLine/text) as one object (That's what i like most).
So here it is.Maybe some of you will like to use it
