A question of scaling

[Dundee901]

I'd appreciate some guidance  - a second opinion really - on scaling imported objects.  

 

A client has sent me a PDF of a garden plan (probably hand drawn, it's a few years old) and asked me to use Vectorworks to work out areas of lawn.  There is no annotation, no scale bar and no other measurements shown on the plan - except that it has a nominal scale of 1:200.

 

I create a new file and import the PDF.   I cannot use the Modify  > Scale Objects command to correctly scale the PDF object as I don't know any distances.

 

However, before importing the PDF, I changed the Layer Scale to 1:200 in the Document Setup.  Then I imported the PDF.    Can I now accurately measure straight off the plan, without any further scaling?

 

This seems a very obvious question but I just wanted to check!  Following import, I have used the tape measure tool to measure some objects on the drawing whose size I can guess (e.g. a doorway, step treads) and I get sensible/believable results but that's not very scientific!

 

Thanks

NO!!!!

 

It is very unlikely that the scale came in correctly.  You are going to have to get a real world dimension of something on the plan that you can then measure and scale the drawing to.

Thank you for making that very clear, Pat!  Appreciated.
