scaling viewports for CAD

[shipleyscott]

I have seen several posts on this topic but none seem to hit the nail on the head. Maybe someone can dumb it up for me. I have a metric drawing and have set up a viewport to plot it.

My sheet is a metric expand A1

My units are meters

I would like to set the viewport scale to 1:400 but if I do that my drawing is just a dot in the viewport. It appears to me that the viewport scales still take into account inches in a foot (the factor of scale of a typical of 1:20 plot). Is there a way to set it all up such that I can put in a unit such as 1:400, plot this guy, and then use my hand scale at 1:400 and read correct dimensions?

Just a clarification,is your drawing done in full scale? If so, you just create a viewport within your title sheet, then,double click on the viewport for you to go in the model space and zoom it into 2.5xp.

in addition to above reply. after you zoom to 2.5xp then plot to scale 1:1

sorry that I'm not so good at this, I learned autocad from a "for dummies" book. what is xp?

 

[1005123]

xp means scaling factor for zooming on exact scale. just type in command promt ; zoom>scale>2.5xp

2.5 is a factor of 1000/400

Hi,

first I would draw the layout in mm. A2 -> 594/420 units. Then create the viewport -> click into the vp (or "_.mspace") -> type "zoom" -> "2.5xp" (like 1005123), now You have the scale 1:400 -> pan the modell into the right position -> go outside the vp...

Did you get the results you were after?

 

[shipleyscott]

I believe that I did. Our client in New Zealand thinks that the dimensions are off, but if I check the dimensions, on screen, or with a metric scale, I get the right answer, so I believe that it is right.

The proper scale factor for Metric to imperial is not 2.5 it is 2.54. This could be why your client is noticine an error.

Don't forget to "lock" the viewport...
