raster scaling

[asdrubale23]

Hello everyone, I hope to be in the right section.

I have a doubt about autocad.

I have a 1:500 scale raster image that I have to scale 1:100 or 1:200

and so far no problem.. .

on the scaled raster (1:100 or 1:200) I must draw in a very coarse manner of the vessels of diameter 60cm placed at a distance of 2mt from each other.

placing the raster in scale 1:200, what design unit should I enter to have circles with diameter 60cm and placed at the distance of 2 mt?? ?

Thank you.

in autocad is not drawn in 1:200 scale, nor 1:100 but 1:1!
scale your raster so that 1m matches 1 unit and draws 0.6 vessels at distance 2

raster the port from 1:500 to 1:200 using the 2.5 scale factor

I don't understand the next step... but I try

it seems that you have not read the directions of tristan:
