Problem on drawing scale
Hello guys,
I'm new to autocad and I'm having a little trouble regarding to scale of objects. I recently convert drawing from PDF to CAD but the sizes of the objects are different compare to the objects I want to add. Please see the image below. Please help me.

Hi,
the PDF does not hold any distances except the page size, so if you printed something with scale 1:50 to the PDF you need to scale back with factor 50 to get the geometry in the correct size.
If you don't have the scale within the PDF then you can use command _ALIGN to get the PDF-object scaled/rotated/aligned to an existing geometry. If you don't have a geomtry in the drawing then look for any object in the PDF which has a dimension (printed in the PDF), create a line in your AutoCAD with the distance of that dimension value and use then command _ALIGN and use this dimensioned object in the PDF as reference in the PDF and use your line to be aligned to.

Hello Sir Alfred,
I already determined the size of the PDF, it is in A3 size. How can I re scale it on CAD on 1:100? I already convert it to Autocad file but the sizes are wrong.

Hi,
>> How can I re scale it on CAD on 1:100?
Run command _SCALE and use factor 100
But that should not be necessary if you follow the _ALIGN command approach from my first post.
But be careful: by default you draw in CAD always 1:1 (in your units) and not scaled.
