Re: [libreoffice-users] precision of Draw dimensions - 3 place

A bit of a rant. My apologies and respect to all who have made Draw 
possible in advance.

Thank you for pointing this out.

If I insist on the inch system, I should use inches.  Not meant to be 
harsh, but really?
Can't debate your math, but shouldn't data be entered as it is measured?

Using points makes "Dimension Lines" that result in points, not inches.

The "Draw" package should draw. "Artist", "Architectural", 
"Engineering", "Diagram", "Composition", "Graphic", "Technical"...

It does cover most of these well. Just not all.

Yes, I do have a CAD program (overly complex - wrong tool) and my 
frustration using it is because I can't use Draw (functions beyond CAD - 
right tool).
