Line weight problem in layout

[arnouddatema]

Hi there,

I'm using AutoCAD 2014 for Mac. I'm drawing a detail which contains different lineweights and they show correctly in model space, but in layout all the lineweights show up with the same thickness. I've tried many things and apparently I changed something in one of my layouts which causes to show it correctly now, but I have no clue what I've done  In my other layouts it still shows the thickness wrong. Anyone got an idea how to change these settings?

Thanks in advance,

Arnoud.

Hi Arnoud,
How do you set lineweights in Model space? Do you use BYLAYER option and set lineweight for the Layer? Or you assign lineweight individually by object?
Have you checked viewports overrides for lineweight property for problem viewports?
Have you tried to select viewport, right-click on it and select "Remove viewport overrides for all layers"?

Hi, thanks for the quick respond.

I've assigned the lineweights individually for each object. I've tried the "remove viewport overrides for all layers", but nothing changed. I'll explain my problem with some screenshots of one of my drawings.

First my drawing in Model, as you can see the lineweights are shown correct (0.25mm).

This is the same drawing shown in layout, which at first sight looks good as well.

But then when I zoom in, the lineweights also become thicker.

 

And then the final screenshot, a print preview, which also shows thicker lineweights than originally drawn. (Also the drawing shows a bit gray, any idea how to fix that to black?)

I think it has something to do with 'linescale', but I'm not sure. 

Thanks for helping,

Arnoud.

The thickness of the lines you see in Model and in Layout in AutoCAD is only approximation. When you zoom in lines became thicker, but only on the screen. In the drawing itself the thickness of the lines stays unchanged unless you change it by editing the properties of objects.
The same I can say about plot Preview. Although Preview app shows lineweights more correctly than AutoCAD drawing window, there also could be some approximation.
The only way to check real lineweights in PDF output is to open PDF file in some application capable of editing PDF file (Adobe Illustrator or Inkscape) and check lineweight via properties of the object.
About "the drawing shows a bit gray" - to say true, I can not see "gray" on your screenshot,
