Dimensions in Drawings

Good day,

Please help!! How do I rotate a dimension (text) from horizontal to vertical. The dimension is a horizontal one but we want the text to be displayed vertical. This is for 1 dimension only, the rest must be displayed as per document settings. We are on SW2011 (SP03 and SP04).

Regards.

Chris Botha.
