Rotating view messes up texts using truetype font

[woolsock]

Hi,

 

I have single line text in my drawing and I’m using truetype font. When I rotated view counterclockwise and back using the viewcube, all the texts went somehow thicker. Also when I plot the drawing to pdf, texts are not anymore searchable.

What causes this thing? I would like to rotate my drawings without text messed up.

 

 

I attached some example files.

Welcome to Cadtutor.

 

The short answer is that "something" happened during the rotation to cause the view "Target" Z-value to become non-zero, and TrueType fonts only display correctly when they are at zero elevation (relative to the UCS)

 

You can verify that the Z value of the view "Target" has changed using the VIEW command, and you can correct with DVIEW>TArget.

Text is a 2D object. Using the cube (a 3D tool) to rotate your view could take you off the Z axis, if you don't do it right, thus messing up the appearance of your text. Changing the VIEW back to PLAN fixes the error.

Yes, TrueType fonts have to be viewed perpendicularly or else anti-aliasing (font smoothing) is disabled causing TT text to appear bold/jagged, but I don't believe that's the case in this instance. Plan>World "fixes" the 2nd drawing because Plan>World also resets the view AND the Z-Target, but PLAN alone will not necessarily correct the text display in a rotated View or a rotated UCS.

I don't understand the point of your post. I took the parameters of the question, found the cause of the problem and how to fix it. What we both missed was answering the second question.

I checked the view and target Z was 0.25. You could assume that this value remains zero if I rotate view only in XY plane by using the viewcube but apparently you can be wrong.

 

Anyway, I got the text back to normal using Dview -> Points -> 0,0,0 and 0,0,1 (didn't quite understood the target command). Thanks for pointing to right direction.
