Have you ever wondered why some of the texts in your drawing are printed in different lineweight?
1. Is there any problem with the plotter?
2. Is either each text in BOLD?
If all your answers are None and No respectively and still having the problem,
Here is a guide for the solution.
Investigating an error is a bit annoying. The image from the left side shows the two selected text were almost all the properties are equal and so the last option for many is switching from different
TEXSTYLE to fix the issue.
Here comes AUTOLISP to INVESTIGATE the issue:
Type or `copy and paste` at the command prompt the following and hit ENTER
(cdr (assoc 10 (entget (car (entsel "\nSelect text: ")))))
then select the text which is having a problem. In my case, the output is
(139.932 223.548 1.0e-005) in which this shows the (x,y,z) coordinates. As you will notice z-value is almost zero whereas on the Properties Pallete>Geometry>Position Z it shows plain ZERO.
Now start selecting all the text and replace the value from Properties Pallete>Geometry>Position Z into 0.00000 or any trailing zeros you wanted.
Enjoy your CAD day!
