Hi all, I have been back on my house plans for a day and one thing just occurred to me: I am having trouble setting a scale. It sounds simple enough: pick a unit, call it X mm's and carry on. But, the plans have been to a draughtsman and back, into the scanner and onto a bottom layer. So I am tracing (drawing over) those drawings and his scale is 1:100 which after the scan and the resize to fit A4 is anyone's guess :)
So, my idea is this: Have a tool that one can snap from one point to another -- say along a line of known world length (call it 6000mm) and have it set the the grid size accordingly.
I'm not gifted numerically, so giving particulars is unlikely to happen soon, but I'd say that if the grid could mark-off 1 "meter" and 0.5 "meter" lines according to the 6000 "mm" ( which is some random pixel count after all the resizing/scanning ) such that they visually match that same line - it would be very helpful.
So, after using the tool, I'd be able to draw a line next to the original (which is marked at 6000mm) and my line would be (say) 600px. I'd also have a grid across the whole drawing set accordingly. (Oh, while I'm on it - a way to click a point on a corner of the drawing to say : start the grid here!)
I guess it would have to fiddle with the overall matrix of the drawing, but here I lose all credibility :)
Sorry if this is garbled, I'm still waking up and in a rush to meet the builder and ... I gotta go!
Now - go forth and write code because *I* said so :D :P
