I don't think vertical justification works, even in the UI. Not for simple notes anyway.
It works for a table annotation.
Why would you want to vertically justify a note?
I try to do a macro in order to automatically create the tittle block on a drawing to install it on all the computers in my company, my aim is to create an userform where you can tip all the modifiable data then simply click on a button to make the tittle block appear. So far we just have pre-made title blocks that we insert in our drawing, but we have to partly manually fill it, and as soon as we need to change something (like the logo of the compagny or the product reference) that means to go through all the old plans, get in the tittle block, change the datas and so on.
So I created the lines and set the position of the texts accurately between those lines, the only problems is that without the vertical justification the text isn't well located. I can cheat and set the position a bit higher but then if somebody want to change the police or if there are several lines in the note, it's not correctly placed anymore.
I don't know if I've been really clear...(haven't spoken english in a while) but if you have any suggestion (I don't know if I could manage it with a table for example) I'd be greatful.
