We have a drawing in Architectural scale and want to convert it to Decimal. How do we do it?
Format>Primary Units>Decimal>Precision (whatever you want). Then go to Dimension at top and pull-down until you find Update. Pick Update and window the entier dwg.
This topic seems to be a little mixed up... You have a drawing done in architectural units (I assume you mean units and not scale), and you want to convert it to decimal. This means changing the units so that what used to read 3'-0" now reads 36.00. Is that what you want to do? Or do you want to convert your drawing from inches to millimetres? In that case, you have to a) change your units from architectural to decimal, AND b) scale everything up by 25.4 times. (I don't know where that 1/12 came from!). This means what used to read 3'-0" now reads 914.4. Is that what you want to do? If you need to go from imperial to metric, then another alternative would be to leave the drawing objects be, but change the DIMLFAC in the dimension style to 25.4. To do this, open the Dimension Style Manager with the relevant style current, then go to the Primary Units tab. Set the Measurement Scale Factor to 25.4.
re-scale the drawing.... Kinda sounds like they did that, but the drawing itself was originally drawn with 1 ft as the drawing unit. They said they wanted decimal but didn't say what unit they wanted. Apparently feet was not what they had in mind....
The OP said they wanted to convert the drawing. They said nothing about dimensioning. Or did I misunderstand them? re-scale the drawing....
