One very light lineweight not printing correctly in 2024

[gmoffatQKN3Z]

I've wasted too much time chasing this down, so hopefully someone else has some different ideas here.

I'm the guinea pig for the upgrade to 2024, and there is an issue with only 1 layer printing at an incorrect lineweight. The layer in question is set to print out at 0.03mm. This has worked just fine for years, and still prints correctly in AutoCAD 2020, the version we're upgrading from. On the page, it looks about the same as another layer with a lineweight of 0.25mm.

• Both versions of AutoCAD use the same ctb file
• I've compared both of the plot windows side by side to make sure the settings are the same. They both have the "print object lineweights" and "print with plotstyles" boxes checked.
• Clicking the button in the upper right of the plot window to edit the ctb file, I've compared this from 2020 to 2024 as well to make sure one version isn't pulling the wrong ctb file for some reason. Everything in there matches from 2020 to 2024.
• I even made a brand new ctb file from scratch in 2024 to make sure that wasn't causing any issues. It wasn't.

These settings are the same in 2020 and 2024:

• LWDISPLAY on or off makes no difference (but this only controls the on-screen display of lineweights I believe)
• LWDEFAULT = 25
• LWUNITS = 1

We skipped 2021 and 2022, so I can't try those versions. I have 2023 installed to test from several months back, and it has the same issue. We got busy and I didn't get to fully test it, so I didn't notice the issue until testing out 2024

It seems like there is some setting or variable that needs to be changed to get 2024 printing properly. Any other ideas where to look?

@gmoffatQKN3Z Share a sample DWG file with this issue here, make sure you point to it clearly, along with whatever is needed to replicate your issue like plot style tables etc. for others to test here please.

NOTE: if you cannot replicate the issue in a sample DWG file, then INSERT then EXPLODE that problem file in your sample file and test, it's probably all gone then.

TIA

Here is a sample of the file and ctb file we use. In the drawing, the tan color on the left is brick tile that isn't printing right. We like printing that out light (0.03) otherwise it is a blob of black that isn't as easy to work with. There is some cyan in there too that prints a little heavier (0.18), the yellow (0.50) is the border of the panel, and the magenta (0.70) is the drawing border. The brick tile only shows heavier than it should when it prints out. It currently prints heavier than cyan when it should be much lighter.

Are these the same?

11x17? no scale? "display"? for an area that measures ~12footx12foot? All these things can produce undesirable results

DISPLAY

Area in question

I can see how you might get a blob if your chosen WHAT TO PLOT is not the good option.

R2024 in Win10Pro here.

The plot styles are similar. The ctb I uploaded prints in black and white only. The other one you see has certain things in color, but lineweights are the same between the two. We print a view (V2 in this case) from paper space on Arch C.

@gmoffatQKN3Z as you can see from the attachments in my last reply, I had no issues plotting PDFs from your files here in AutoCAD2024 (and AutoCAD2023).

And since you added the nugget "...  We print a view (V2 in this case) from paper space on Arch C..." here is that too

[gmoffatQKN3Z]

I may have moved something inadvertently when cleaning up the drawing to share which is why it's not centered

I can print but the lineweights on hard copies that aren't right. The PDF works for me too, but I don't want to add that step of printing to a PDF, then printing the hard copy of that. In 2020, we can still print out the hard copy and it works the way it has for a while.

What device and driver are you plotting to exactly? I can plot your DWG's V2 "view" from model to our HP + SHARP printers and the HP plotter with the same results as the PDFs I've shared, hardly any differences here.

If your own PDF outputs are not problematic either, then your problem is with the device driver (or PC3 file) you are using, not much else.

[gmoffatQKN3Z]

I've thought it was the driver as well, but 2020 doesn't have any issues, and it uses the same driver.

@gmoffatQKN3Z ,

I suggest you check your CTB has the proper lineweight assigned to your colors mentioned in message 3.

Otherwise, "Use object lineweight" in the CTB and assign it the weight in your layers.

Last resort would be to:

• How to reset AutoCAD to defaults
• How to repair or reinstall an AutoCAD installation
• Clean uninstall of AutoCAD or verticals
