Task Description

Loading any larger dxf file takes very long because of this line:
istr.imbue(std::locale(”C”));

The call to std::locale is very slow. File-loading can be speed up by approximately factor 5 times on my system when replacing it. I just removed that line and instead added the following in DL_Dxf::in so it is changed only once per file:

std::locale oldLocale = std::locale::global(std::locale(”C”)); // use dot in numbers
while (readDxfGroups(fp, creationInterface)) {}
std::locale::global(oldLocale);

 1662 QCAD (main)Performance IssueLow Select > Select Contour: slow for complex drawings Closed
100%
Task Description

Hi!

when working with files containing many not connected elements (non-poly-line elements) a double click can cause a coffee-break easily. The search for connected entities easily takes over 5 minutes on an up to date machine ([email protected]) with files that are pretty standard in size (2 or 3 MB file size ascii dxf). Adding an interruption-method would be suitable (for example by pressing escape).

attached a file with a polyline of 13000 entities and a second file with just everything duplicated. When exploding the polyline and double clicking an element it takes quite a while until all elements are selected. (this is not an extreme example, I had sometimes 10 minutes of waiting with slightly bigger files, accidently double clicking something).

also an improved algorithm for the search would help to speed up the selection. (e.g. divide the area in smaller parts, do the search there, or an option to search only in the visible view port of the document)

2021QCAD (main)Performance IssueVery LowCannot work with big dwg filesAssigned
0%
Task Description

Openning a big file or doing any action in it, takes minutes to load.
Even dragging the scrollbar slightly left or right, takes mintues to redraw the canvas again, which makes QCAD un-usable for professional use.
Is there a way to make QCAD usable, after loading completed:
- Like suppressing edit until user says so,
- or taking snapshots of rendered canvases to another file and use it, as windows uses thumb.db ( for negative latency :P )

PS: I wish I could help a bit, but my hand are tied. I am just a java freak, I am opt to any idea of porting it to java, if she is still alive.

 137 QCAD (main)RefactoringLow SVG Export precision Closed
100%
Task Description

In files exported with the (even PG) exporter I sometimes see values like these: 334.99999999999994 or 570.0000000000001 and very often 12 digits of precision.

To safe on file size, I suggest, that QCAD rounds values on SVG export to eg. three places. When viewed in an ordinary web browser, that will result in a precision of 1 inch / 96dpi / 1000 = 0.00026mm, not? Ends should still meet.

 138 QCAD (main)RefactoringLow SVG Export entity properties "By Layer" and "By Block" Closed
100%
Task Description

If I understand correctly, SVG export uses svg groups to keep QCAD block entities. This in itself is very useful. There is no way to correctly keep layer information, as QCAD blocks can contain elements on different layers, while SVG only knows about groups. That is a deficiency of SVG.

To save on file size, there was some potential to get rid of ever repeating same attributes on entities, eg: style=”stroke:#000000;stroke-width:0.25;stroke-dasharray:2.16,1.08”

To optimize “By Block” is easy: just set the attribute on the SVG group, and omit on below entities styled “By Block”.

To optimize “By Layer” is a little more involved, but might be solved by using css:
- Create a class by the name of the Layer
- add the class attribute to elements styled “By Layer”

Then only individually styled entities would get a style attribute, and filesize of SVG could be halved in most cases.

This just an idea :) Having written this, I now realize, that QCAD can style weight, pattern, color each extra, so the optimazition could only be applied to entities, where everything is “By Layer” or “By Block”. But that should be the case most of the time.

Task Description

QMdiChild widgets in an QMdiArea receive repaint and mouse events even if they are not active which slows down the user interface when having multiple MDI children open.

Long term, QMdiArea might have to be replaced with something else.

 1056 QCAD (main)RefactoringVery Low Dead and wrong code in RSPlatform.cpp Closed

I am considering pushing the following diff:

 #endif

(truncated list to manage size)

I see that most of this was put in there as a kind of a note-to-self originally, however _SC_NPROCESSORS_ONLN is implemented by every realistically possible targets anyway, so for all practical purposes, this is dead weight.

A couple of questions remain, though:

  • #ifdef Q_OS_WIN32 should probably be Q_OS_WIN, so as to include win64 as well.
  • Assuming the real purpose for this function is to determine how many parts a particular task is to be split into in the future, if and when QCAD gets the need to split expensive tasks among multiple CPUS, “core” probably shouldn’t be static - CPUs are hot-pluggable today, and while one probably doesn’t do that on a laptop, it’s not unfeasible in, say, a VDI environment.

Thoughts?

 1328 QCAD (main)ReleaseLow Windows 64bit install dir Closed
100%
Task Description

I only noticed today (perhaps they were available earlier?) that there are 64 bit binaries for windows; I suppose these are true 64 bit.

Yet, the installer prompts me to put them into “Programs (x86)”, where all the 32bit software lives, I guess - this seems to be a pure convention though, the application runs just fine.

Maybe the reason is, that the 32bit version was installed before; Maybe it should change? Maybe it should stay, so that there are not two?

1323QCAD (main)SuggestionLowImprove command line support in QCADAssigned
0%
Task Description

Hi,

As a typical command line draftsman (still using acad10 for dos, since microsoft doesn’t supoort Win NT anymore),
I noticed a severe lack on command line acces in QCAD.

For example I find the icon and pixel selecting methods within qcad very confusing and rude.

With the normal cad Select command I can select exactly what en how I want it.

I intend not to be rude, but I find my drawing screen littered all over with all kind of very specialist menu’s,
tools and options. Sorry, I just want to make a drawing at the natural intuitive way, as with a pencil.
So I use command line Commands, such as Move, Copy, Change, Select, a.s.o.
For a ‘Command scripting’ user (-batching is a different tool!-),
it seems to me logical these basic commands should be accessable.

 1375 QCAD (main)SuggestionVery Low Install in hidden folder Closed
100%
Task Description

After each update, I add a dot before the ~user/opt folder (and in the program launcher) created by QCAD to unclutter my file manager’s appearance. Would be easy, I think, to make the installer put the program directly in ~user/.opt, and nobody would miss that folder while browsing through daily used files.

And what about installing the program as root, so all users of a computer could use it without personal installs, and only personal setting files created by users would be kept in ~user/.opt/qcam.

 1534 QCAD (main)SuggestionLow Headless Styling Closed
100%
Task Description

Since the launcher batch no longer requests “-style plastique” QT wants to apply the native style of the desktop environment. This fails on a headless system (or where the current user has no graphical shell to connect to) with the message “Gtk-WARNING **: cannot open display: “. Fortunately, QT provides a workaround in addtion to the new “platform=offscreen” flag.

In the tools that set -no-gui, beforehand export these variables into the environment

export QT_STYLE_OVERRIDE=""
export QT_QPA_PLATFORM=offscreen
export DISPLAY=""

PS: QT-offscreen will not find fonts; unfortunately the workaround only allows for a single directory to search them (I need helvetica):

export QT_QPA_FONTDIR="/usr/local/share/fonts/type1"

Maybe that should get reported upstream, so that like LD_LIBRARY_PATH several directories could be specified.

Task Description

Hi Andrew,

I was fiddeling around with a copy of the hpgl postprocessor, and has it adapted, up and running for a HP7580 penplotter. You may add this to QCAD if you like.

Poking and peeking in the other postprocessor files, I found enough information to generate a very acceptable hpgl.plt file now, including the required pen changes.

The purpose of a ‘bracket-field’ (as [S] ) is clear to me. Where are [S#] and [S!] used for?
