I just updated to 3.24.3 (luckily I saved 3.24.2 since the problem doesn't appear there) and my print previews and actual printed output is very low resolution. I'm attaching two examples of the same drawing - one from 3.24.2 and one from 3.24.3.
Is there, perhaps, some new setting in 3.24.3 that needs to be adjusted to compensate for this issue?
I'm running QCAD on a iMac Retina 5K system using the latest MacOS - version 10.15.3.
Thanks.

Not sure .... but maybe you should play a bit with this settings:PiperPilotJohn wrote: ↑Sat Mar 21, 2020 11:21 pmIs there, perhaps, some new setting in 3.24.3 that needs to be adjusted to compensate for this issue?

Re: 3.24.3 Low Resolution Printing
Husky,
I checked the settings you mentioned below - the only difference was that "Auto switch..." was not checked, so I checked it. That helped a bit. With that said, there is still an obvious problem between the two versions. For example:
1) If I switch to Print Preview mode with the full drawing displayed, the drawing appears as lower resolution.
2) If I then zoom in the resolution of preview mode gets even worse.
3) If I zoom in before switching to Print Preview mode, the resolution isn't as bad, but it's still not correct.
The program appears as though it's not using the line weights as set for each layer. This drawing does specify a line weight per layer so the defaults should never kick in.
Something has definitely changed between .2 and .3, at least on the Mac.

Re: 3.24.3 Low Resolution Printing
The resolution of both PDF's is identical.
I think your question is about the difference in lineweight. I can see that the drawing likely uses hairlines. Unfortunately, these hairlines (0 width) cause a lot of problems for many users as on most printers they are not printed or printed extremely fine and in some PDF viewers they don't show up. QCAD 3.24.3 avoids using hairlines. To be sure if that's what causes the problem, please attach your DXF as always.

Re: 3.24.3 Low Resolution Printing
Hi Andrew,
Thanks for the quick reply, as always. Sorry that I forgot to attach the DWG.
Well, I'm not sure what you're seeing differently than what I'm seeing, but the resolution of the drawings, or at least the way in which QCAD is displaying the line weights, has changed between the two versions. It's true that many of the lines which you call "hairlines" are using the default line width, which is set to .25mm in Graphics View/Appearance. I certainly can change the layers set to "default" to a specified line width to see if that makes a difference. In the meantime, I'll leave it alone so that you can check the original drawing as is.
The "Text" layer is also set to the "default" line width.
I'll attach the drawing for you and we'll see what you come up with. It's easy enough to change each layer to a specified line width if that'll fix the problem.
Thanks.
John

Re: 3.24.3 Low Resolution Printing
Thanks.
Yes, this seems indeed to be related to the default lineweight used, especially for layer "0". You can change that or change the default lineweight in the application preferences from 0.25mm to 0.00mm (see Husky's post above).

Re: 3.24.3 Low Resolution Printing
Andrew,
That does, indeed, fix the problem. And I just noticed something in Edit / Application Preferences / Graphics View / Appearance:
3.24.2: Does not have a setting for Linetypes / Default Lineweight
3.24.3: This section of the dialog is now called "Linetypes and Lineweights" and has a setting for "Default line weight:"
And that must be the change that occurred between versions that caused my problem.
From now on I plan to set a line weight for each layer to prevent this from happening again.
As always, thanks Andrew!
