Text resize on different scale

[amar5326]

Hi to all members,

 

Firstly, I'm still learning autocad for land survey purpose and please excuse my english.

 

My problem is,

 

When I create new drawing, for example, the drawing looks good in 1:400 scale and text I use 1mm height for bearing & distance and it looks good and readable(not too big or small). However, when I create the new drawing and scale it to 1:2500, I don't know what size should I set for my text so it will looks good and readable.So, my method is to set random size so it would look good in model and paper size the print it out.But, sometimes, the text will looks big or too small on actual paper. Then I need to repeat the process till it readable.

 

My question is, can autocad scale the text size automatically when I create new drawing at different scale or you guys got any useful formula for text size on different scale. Hope someone can help me. I'm using autocad 2010 and my drawing in metric.

At 1mm, height, it sounds like you are doing your text in paper space, so if 1mm is legible, it will always be legible no matter what the scale of the property lines etc. in model space. In paper space 1mm would be the actual height that it will be printed out on the paper, so 1mm on one sheet of paper is the same as 1mm on the next sheet of paper even if the boundary/property lines are a different scale.

 

If your text is in model space you can just come up with a factor to enlarge it by, for example when I used to do text in model space if I went from 1/4"= 1'-0" (1:48 )to 1/8 = 1'-0" (1:96) I would divide 96 by 48 to get 2, so two times whatever height I used in 1/4"= 1'-0" (1:48 )scale.

In your case take 2500 divided by 400, which gives 6.25 times whatever text height you are using, but again, this is really only if you are putting your text in model space.

If you are doing your text in paper/layout space, it's really just a matter of preference if you want to scale it up between different drawing scale. I actually think that's the best thing about putting text in paper/layout space - you DON'T have to change the text height between different scales.

If you measure the height of text that has been printed out on paper and then multiply that by the scale, you will get the text size for model space.

 

I would have thought that 1mm high text would not be clearly readable. Perhaps it should be 1m in model space (assuming that you are working with metre units). At 1 to 400 that would give a printed text of 2.5mm high which is much more readable.

cadmonkey is right, the best way to do it is to place your texts on layout so no matter what scale you are, the texts will be of the same height and you dont have to change them all when using different scales. i also place my dimension on layout because of this concept. and one mm is actually too small to be read if your work is scaled properly, how can you read a text which is 1mm in height?.

"My question is, can autocad scale the text size automatically..."?

 

Not quite but almost. That's only if you use annotative scaling and place all of your text in model space. The text is then assigned the various scales of the viewports you will be using to display your model space objects in your paper space layout. If your viewports are 1:200 and 1:400 then these scales would be also assigned to your model space text.

 

Have you looked into annotative scaling in AutoCAD yet?
