AutoCAD Civil 3D

[#1]

We have a few drawings where the lineweights between paper space and model space vary on plots.

ie a line on Layer 1 in model space plots heavier/darker than a line on Layer 1 in paper space.

Why is this happening?

[#2]

I can think of two possible causes:

1. You have a layer override in your paperspace viewport.
2. You have different Plot Style tables assigned.

[#3]

No overrides. 

In the layer properties, everything matches between paper and vp settings.  Unless there is another setting somewhere I have not noticed?  (please let the answer be this simple)

This has happened in the past on acad and ldd programs so its not limited to C3d.  Not all drawings do this, but some.  Makes me think it is a drawing setting somewhere.

HI Isimms,

What happens if you change plot scale. Does the lineweight changes? If it does, then check your Plot dialog and the "scale lieweight" toggle setting.

[#5]

Not that either.

Keep the guesses coming.  Sooner or later there will be the right one.

Did you ever figure out what was causing your issue?  I have the same thing going on in my drawing.

[#7]

Sorry, no answer for you.

It may be a plotter setting issue. (?)

Lately I have been plotting to pdf, not a plt file or direct plot.  Have not had it happen since.
