Hi Toby,
Sorry for the delay in replying; we've been having some problems with the Forum Post notification system.
I'm a bit baffled by your request because on the face of it a Dimension without the measurement text loses its sole purpose for existence; it feels a bit like asking for the option to hide the characters in a Text object.
If the overlap of the measurement and the leaders is the problem you could:
- Move the text to a better place (just drag the handle in the center of the baseline of the text)
- Change the Font Size so that it fits
If you really want to hide the text today you can achieve that effect by setting the Font Size to a tiny value e.g. 0.001mm (Note that zero height text in the Dimension object is reset to 1 so you need to set a tiny value that is greater than zero).
But to hide the measurement text begs the question why have the Dimension there at all? Perhaps I don't understand the problem you're trying to solve; please let me know if I've missed the point.
