 1324 QCAD/CAMSuggestionVery Low Confusing Copy / Move option Closed
Task Description


Using the Copy and Move command the [ ] Use current layer and attributes’ is confusing.

Perhaps [ ] change copy /moved set to current layers and attributes. is more suitable.

 1369 QCAD/CAMBug ReportVery Low qcad-bin is trying to access non-existent /home/andrew Closed
Task Description

I experience long start delays. I’ve trace the problem to the fact that I have autofs automounting my home directories. However, an strace of qcad-bin shows the following:

execve("/opt/ribbonsoft/qcad/qcad-3.12.6/qcad-bin", ["/opt/ribbonsoft/qcad/qcad-3.12.6"...], [/* 87 vars */]) = 0
brk(NULL)                               = 0x1eca000
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fd6194ad000
access("/etc/ld.so.preload", R_OK)      = -1 ENOENT (No such file or directory)
open("/home/andrew/local/qt/lib/tls/x86_64/libqcadecmaapi.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat("/home/andrew/local/qt/lib/tls/x86_64", 0x7fff4722f250) = -1 ENOENT (No such file or directory)
open("/home/andrew/local/qt/lib/tls/libqcadecmaapi.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
stat("/home/andrew/local/qt/lib/tls", 0x7fff4722f250) = -1 ENOENT (No such file or directory)
open("/home/andrew/local/qt/lib/x86_64/libqcadecmaapi.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)

stat("/home/andrew/local/qt/lib", 0x7fff4722f250) = -1 ENOENT (No such file or directory)

Since there is no “andrew” user here, I have to wait for automount to timeout which takes about 2m and is rather annoying.

 1375 QCAD (main)SuggestionVery Low Install in hidden folder Closed
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.

Task Description

There is no “X/Y of position” and “Y/X of position” snap function in Tool matrix.

 1377 QCAD (main)Bug ReportVery Low CE - is asking to save an untouched drawing Closed
Task Description

If I launch the CE edition / do nothing with the empty default drawing and then try to terminate QCAD an unexpected warning pops up:

Do you want to save the changes you made in ‘Untitled 1’ ...

Hey - I haven’t change anything and there is nothing what needs to be saved ... ;-)

 1384 QCAD (main)Bug ReportVery Low Lost Icons in Context Menu Closed
Task Description

When I press ALT + Left mouse click to select overlapping entities - afterwards the icons in the context menu become lost until I restart QCAD again!

 1400 QCAD (main)Bug ReportVery Low Layer > Add Layer: layer name not selected by default Closed
Task Description

Text in layer name input with default layer name should be selected by default, so it can be replaced without deleting text first.

 1417 QCAD (main)Bug ReportVery Low Dimension: missing tolerance icons in options toolbar Closed
Task Description

e.g. Dimension > Horizontal: tolerance inputs should have an icon next to them.

 1424 QCAD (main)Bug ReportVery Low Edit > Undo: hatches not selected Closed
Task Description

If a hatch is selected, then rotated or scaled and this is undone afterwards, the hatch is not selected anymore.

 1459 QCAD (main)Bug ReportVery Low  File > Revert: changes grid appearance Closed
Task Description

... even if it wasn’t used in the saved drawing.

 1460 QCAD (main)Bug ReportVery Low Two Display Environment --> Problems with Toolboxes and ...Closed
1 Task Description


I’m unsing a two display environment and got all Tools and Widgets placed on the second display.
See qcad1.png

There are two problems:

1.) When I open another application on second display, three toolboxes stay on top, the others are behind new application.
See qcad2.png

2.) When I minimize Qcad only the mainwindow will be minimuzed, all the toolboxes and widgets stay on second display also with problem 1.
See qcad3.png

Whould be great, when this issues will be fixed :-)

Thank you very much

P.S.: Hope described well, if not, please drop me a reply...

 1518 QCAD (main)Bug ReportVery Low Landscape/Portrait gets confused for custom page size Closed
Task Description


In the Print Preview or Drawing Preferences / Page Settings if I select a Custom size, then landscape/portrait does not really make sense.

For instance, at work we have a laser cutter which uses a printer driver. The bed of the laser is 600 wide by 300 high. When I wanted to cut
something, I created a custom page size of 600×300 and selected Landscape (because it is wider than high)

Strangely, back in the Print Preview, the page is now sized opposite with regards to Portrait / Landscape mode, which was confusing somewhat.

(see pictures attached)

I think that for ‘Custom’ page size in Drawing Preferences, the option of Portrait or Landscape should probably be ghosted

Then, I think that for Portrait / Landscape mode in the Print Preview, it should display the shape most appropriate, rather than just assuming that the document fits the norm:

  1. Taller than Wide for Portrait mode
  2. Wider than Tall for Landscape mode
 1574 QCAD (main)Bug ReportVery Low Layer > Remove: deleting sublayer switches to layer 0 Closed
Task Description

I have set the delete layer preference to make the next layer in the list the current. This will not work for sublayers. After deleting a sublayer the 0 layer will become current.

 1583 QCAD (main)Bug ReportVery Low Option / Rotation missing defaults for 15 and 345 degre ...Closed
Task Description

... just cosmetic!

The Option drop down list for rotations (e.g. Paste etc) shows all steps incremental for every 15 degree - but 15 and 345 degree are missing.

I’m happy that we don’t have bigger problems!!! :-)

 1587 QCAD (main)Bug ReportVery Low PDF export created with wrong date time Closed
Task Description

Hi guys,

when I export my dxf drawing to pdf, the pdf properties shows wrong “created date”. I am in UTC+2, the date shows 2 hours less.
I exported the pdf at 12:24, the attached ps shows 10:24.


 1607 QCAD (main)SuggestionVery Low Indent 'Spline Segments:' in explode preferences Closed
1 Task Description

 FS#1604  was issued because of non-intuitive hierarchy of the preferences for the Explode function.
The task comment recieved explains the funcionallity in details not found elsewhere.

Indentation of the phrase ‘Spline Segments:’ suggest hierarchy.
Graying out the drop down box for the number of spline segments establish hierarchy.

 1659 QCAD (main)Bug ReportVery Low File > Print Preview: does not always open / close prop ...Closed
Task Description

Drawing with Viewport,
in Model Space - launch Print Preview - Paper size and display ok,
change directly to Paper_Space - Paper size and display ok,
switch back to Model Space - Paper size ok but the Paper display looks infinitive big ...

Print Preview off/on or launching/canceling Drawing Preferences will solve the display issue.

 1660 QCAD (main)Bug ReportVery Low Draw > Viewport > Add Viewport: viewport in model space Closed
Task Description

... I have the feeling that wasn’t the idea. I’m correct?

in Model Space, launch Add Viewport, determine the Viewport rectangle - when done QCAD will switch to a Layout Block.
Now in Layout Block, don’t(!) place the Viewport, switch back to Model Space and the Viewport is still attached to the Mouse pointer and you can place it in your Model Space. The source of the Viewport will then disappear.

 1668 QCAD (main)Bug ReportVery Low Text color of command line unreadable with KDE's Breeze ...Closed
Task Description

I prefer the Breeze Dark color scheme as it find it less stressful on my eyes, however it’s unusable with QCAD where the Command Line prompts and responses are rendered as a very light grey on a white background. I believe the proper fix would be one (or both) of:

  • Make the Command Line area background follow the desktop scheme. (It appears that the text already does so, hence the light text, but since the background doesn’t it becomes unusable.)
  • Provide a configuration option for the text and/or background color used in the Command Line area.

Screen shots are attached showing both Breeze and Breeze Dark schemes.

 1692 QCAD (main)Bug ReportVery Low Issue with Layouts. "Viewport" enteties are not highlig ...Closed
Task Description

QCad 3.19.2 Professional, 64bit, Linux Mint

1. Open some drawing with viewport entities on layout block (paper scace). Print Preview mode is “On” automatically.
2. Switch to “Black/White Mode” from toolbar and move cursor on “Viewport” enteties. This entitie is not highlighted. With other enteties all works as expected.
In “Full Color Mode” and “Grayscale Mode” no problems.

For example can try on “flange.dxf”

Task Description

Not served with the degration to ‘Suggestion’  FS#1759 .
Demanded closing  FS#1759  & re-entered

Locking entities (by layer) to avoid selection,eg. nearby,very close by or on the same spot, does not have the intended influence.

Asumed wrong:
- Modify DI
- Modify B2
- Modify D3
- Modify MT
These 4 need a single entity to be selected and selection of a locked entity is allowed.(=questionable)
The action will allways leed to ‘not allowed’.(=correct)

- Modify RM
- Modify CH
- Modify RN
These 3 need a pair of entities.
RM: Selection of a locked limiting entity is allowed (=questionable), enity to trim not.(=correct)
The action will trim unlocked entities to the locked limiter.(=questionable)
CH & RN: Selection of a pair of entities is allowed.(=questionable)
Trimming if ‘trim’ is on will not occur because locked and leeds to ‘not allowed’.(=correct)
The creation of the bevel or rounding on an active locked layer will not occur because locked and leeds to ‘not allowed’.(=correct)
The creation, except for polyline segments (because locked themself), on an active unlocked layer will be done.(=correct)

Less severe but still questionable: (because these don’t necerally act on the locked entities themselves)
