scale problem..have been doing math for hours but still can't solve it ..please help

[icandobetter]

Hi all

I read the previous posts and tried but still can't solve the scale problem..

I got the original drawing with scale 1:1000, and I need to print it at 1:300.

and I have decided the area for printing.

 

em..I am confused with the paper size and plot scale.

If I choose A2 paper, should I plot the scale to 1:3.3? (in mm)

and does 'fit to paper' option matter?

 

I know this should be simple calculations.. it is a shame that I can't solve it.. :/

hope get some help. thanks!!!

When plotting from a metric paper space layout the plot scale should be 1:1 meaning 1 mm = 1 unit.

 

Plotting anything "To Fit" in most cases is not going to result in a drawing that is "to scale". One workaround would be to include a scale bar.

 

What is the source of the drawing?

Thanks ReMark!

I will not click the "fit to" option anymore!

I get this drawing from the city government.. I want to re-design the selected area (for assignment)

would it be possible that, I opened the file (but forgot to change the default unit from inch to mm), saved the file and uploaded it. so that it shows the unit is inches?

[ReMark]

I would have expected the drawing to have been done in metric units given the "characters" across the top/bottom of the drawing. Chinese?

 

Where are you located?

 

Are you familiar with paper space layouts and viewports?

 

Does the word SCALELIST mean anything to you?

[icandobetter]

yes the characters are in Chinese. they are descriptions of the city area only =]

i am from taiwan...

yes i have been looking into layouts and viewports..but scalelist is new to me though..

 

I tried to rescale the drawing 1000 times (it is said to be 1:1000 in the original) in order to get it at 1:1..

then rescale it again to 1:300..

is this approach acceptable??

sorry for simple questions.. Thanks again!!

[ReMark]

There should have been no reason to rescale the drawing unless it were drawn "to scale" as one might do manually on a drafting board.

 

Do you have an original copy of the drawing file?

 

1:1000 is a ratio. It could mean 1 inch = 1000 inches or it could mean 1mm = 1000mm depending on the units you are working in. Not sure what units are typically used in Taiwan. It seems as though you want to stick to metric units. Correct?

 

In my opinion it would be best if you used a layout and a viewport. Viewports are assigned a scale. Model space objects should not be scaled; they should be drawn full size. Viewports are merely windows that allow us to see our model space objects.

 

Unfortunately I will be away from my desk for a while so I may not be able to respond to your next post. I will check back later however.

I wonder why you need to plot it at 1 to 300

 

I plot from model space, and the image shows an A2 sheet at 1 to 300.

 

Perhaps an A1 sheet at 1 to 500 would encompass the area better

To fit the rectangle you have marked on the drawing, you would need to go to a paper size of A0, using a layout scale of 3.33333333:1, I did find a couple of cars in the drawing and they are 6.5 meters long ? Is there anything in the drawing other than the grid markers, that you know the size of just to verify that the drawing is correct.

thanks all!

@ReMark: attached is the original file. yes in taiwan metric units are commonly used, that's why i thought 1:1000 scale is in metric units.. I am looking into layout and viewports, hope I can upload my version soon! Thanks for your help!

 

@eldon: thank you! I can now clearly see that A2 paper doesn't fit...1:300 scale is required.../.\ did you use layout and viewport ?

 

@steven-g: oh no! A0 size paper is too big...and thanks for spotting out the mega-size cars!!!

1st thing draw a new title block in the layout view at true size for A2 594x420 then add a mview window inside it, your sheet size is very odd. Once in the new mview you can set a scale. this is your project a A2 at zoom extents you can see the little number in the layouts tool bar I changed that to 0.5 which is a true 1:2000 scale.

....@eldon: thank you! I can now clearly see that A2 paper doesn't fit...1:300 scale is required.../.\ did you use layout and viewport ?

 

My method of working is not conventional with layouts and viewports. I do not have need for a conventional title block. I just need to get different sized surveys onto paper at a recognized scale. So I always plot from model space.

 

I have drawn blocks of the paper sized frames at natural scale, I draw an A1 frame at 0.811 x 0.564 units (I also work unitless). This block is then inserted into a drawing at the required plot scale - with your case a scale of 300. The frame then can be moved around until it is nicely placed. Then plotting is done by "window", and the custom scale has to be nudged a bit to get it spot on.

 

My method needs a bit of thinking, but the paperspace / viewport method should be more automatic.
