drawing has been drawn at 1:500 in m/space, how to convert back to 1:1


Recommended Posts

Please help!

 

I have been given a drawing by an old school architect who has drawn the floor plan at 1:500 in model space. I need to use the outline drawing for a space plan but don't know how to convert it to 1:1. I know its dead simple but I just can't get it right! A normal doorway is currently measuring 170.985 mm on his plan?

I'm kicking myself because I really need this plan for the weekend :x

 

I have only ever drawn at 1:1 in model space and then scaled the drawing in paper space!

 

PLEASE HELP!!

 

xxxx very frustrated designer xxxxxxxx:cry:

SCALE

 

500

 

does that not do it?

 

(don't forget to window all the objects)

..and use 0,0,0 as basepoint (if coordinates are important)

isn't there a method of altering the drawing units to tackle this too? (not that I'd expect it's been drawn that way, knowing some of the daft things some disciplines do with their drawings :glare: )

I would have thought that you needed to scale by 5 times. That makes the doorway 855mm wide.

... unless you want your doorway .855m wide

 

buildings are usually measured in m not mm

Yes, buildings can be surveyed in metres, but architects usually design them in millimetres. Aren't we lucky to have a decimal system. I think a doorway of 855 metres would be noticed :shock:

Hmmm, first I think you should use the UNITS command and seth the drawing units that you will use, after that simply use the SCALE function as people advised, I think you should scale it with the factor of 0.2 if i understood correctly and the architect has made the drawing larger not smaller, if it's smaller then scale it with a factor of 5. Make sure coordinates aren'timportant before scaling.

 

As far as i have come in contact with architects then unlike engineers, they ignore coordinates. I have received drawings of important topo information scaled and rotated, then I saw that they had no understanding about how important the coordinates are to an engineer.
