Just a thought .... probably a silly one ...
I use the ability to drag the rulers to a zero point (x=0, y=0) on the drawing a lot. On a boat, the zero point is often the intersection of the forward perpendicular and the datum waterline (in a profile view) or the centreline (in a plan view). And pretty much everything that I draw is relevant to the zero point and the structures of the boat.
When it comes to detail drawings, specially on larger boats, the zero point is way outside the extent of the drawing. This isn't a huge problem, but what I have to do is extend the drawing to enough pages to accommodate the zero point, then create it, then get rid of the lines and the extra pages, so I'm back to a single page (usually A3) and the various items on the page are in their correct location with respect to zero.
So, if I'm working on say a 19m sailboat that is 5.5m beam and I'm drawing an item of interior furniture at 1:10 scale – near the aft end of the boat for example – the zero point is a many pages away from my drawing. And if I have to move what I am drawing on the page, then I have to go through the whole process again!
So, I'm just wondering if it is possible as well as simply dragging the zero point somewhere, it would be possible to click on a line and designate its x or y location – so on my 19m boat, working in say the aft cabin, I might want to designate a vertical line as Position -17000mm (x=-17000), because the structure that that line represented was at 17000mm aft of the zero point. So what I would be doing in fact would be the same as creating a zero point way off the drawing.
It's only a thought – and not important at all – and might be difficult to do – and I don't know how many users would actually use it. And of course I could simply make my -17000 line zero and calculate everything from that. But it's really nice to be able to click on a line and know its real position without having to engage brain too much
