1460QCAD (main)Bug ReportVery LowTwo Display Environment --> Problems with Toolboxes and...Assigned
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...

1518QCAD (main)Bug ReportVery LowLandscape/Portrait gets confused for custom page sizeAssigned
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
1587QCAD (main)Bug ReportVery LowPDF export created with wrong date timeAssigned
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.


1660QCAD (main)Bug ReportVery LowViewport in Model Space ...Assigned
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.

1691QCAD (main)Bug ReportVery LowIssue with Layouts after "File-Revert"Assigned
Task Description

QCad 3.19.2 Professional, 64bit, Liux Mint

1. Open some saved drawing with viewport entities on layout block (paper space). Print Preview mode is “On” automatically.
2. After “File-Revert” drawing is reopened on layout block (paper space), but now Print Previw mode is “Off” .

For example can try on “flange.dxf”

1692QCAD (main)Bug ReportVery LowIssue with Layouts. "Viewport" enteties are not highlig...Assigned
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”

1719QCAD (main)Bug ReportVery LowUndo on converted drawing leads to wrong label position...Assigned
Task Description

Drawing converted from inch to mm - undo leads to wrong dim label position. I can fix that with “Reset Label position” but it would be nice if QCAD could to that in first place.

1743QCAD (main)Bug ReportVery LowDraw > Text: Wrong bounding box for text with empty sup...Assigned
1 Task Description


I have a drawing where I use text with superscript. In this case when I use autozoom, it does not work as I expect. It includes the 0,0 coordinates too. The problem also occures when I export the drawing into svg.

I attached an example, just use the autozoom.


1760QCAD (main)Bug ReportVery LowSelf-crossing polylines can't be cut twice at segment c...Assigned
Task Description

Re-entering dividing problem from  FS#1757 

Divide the poly selecting near segment 1 at the segment crossing.
> A new node is inserted on the crossing and made start and end node.
Divide the poly again selecting near segment 2 at the segment crossing.
> no division appears to be done.

One can’t divide the second segment at the crossing

Presumed intended behaviour like  FS#1750 


1762QCAD (main)Bug ReportVery LowModify // .... selection of entities on locked layer al...Assigned
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)
- Modify OF
- Modify OH
- Modify SS
OF: Selection of a locked base entity is allowed.(=questionable)
The preview is casted only if the active layer is unlocked.(=correct)
The creation is only done on an active unlocked layer.(=correct)
OH: Selection of a locked base entity is allowed.(=questionable)
Selection of point references from entities on locked layers is allowed.(=questionable)
The preview is casted only if the active layer is unlocked.(=correct)
The creation is only done on an active unlocked layer.(=correct)
SS: Selection of point references from entities on locked layers is allowed.(=questionable)
Strechting is only done for unlocked entities. (=correct)

1765QCAD (main)Bug ReportVery LowErrors with polyline offsetAssigned
1 Task Description

Win 7 32 bit QCAD 3.20.1

Ofsset of a base-line with arcs results in massive ammount of errors.
Most of them occur as a cluster of very tiny segments and are part of the offset. (zoom far in at the red circles)
Mostly they occur where the offsetted arcs should merely be trimmend pairwise.
Some occur as detached entities or as detached strings of entities very near the offset (strings not documented).
Spooks occur at opposite site when base-line is not closed.
360° curls can occur with R = Offset.
Null-entities may occur (not documented, hard to find and not able to copy).

The base-line is checked and sound and has mixed tangentially or not tangentially connected arcs.
Offsetting the mother base-line of the base in the file has similar effect but not all and/or different ones.
Also encountered with offseting polys from fonts.
Used to define pocket paths for CNC.
Detected because the CNC driver will not accept Self-crossers, Null-entities or open ends depending on the settings.

Work arround is to explode and select small entities but this does not solves the issues.
1) Choosing the tolerance large enough will detect small segments that should stay.
2) Recombining will generate new ones at the place where the main segments remain crossed.
Cleaning up the paths is a daunting process with some thousand segments for several offsets.

I assume this has an infuence on the CAM part of QCAD too unless the offset method is different.
