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.

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)

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.

Task Description

Required for extreme units such as Nanometers or Kilometers. See also FS#20

38QCAD (main)Feature RequestVery LowSave / restore, export / import settingsAssigned
Task Description

Inside the application preference dialog:

  • save settings (asks for a name)
  • restore settings (picked from a list that contains all so far saved settings and some presets)
  • export settings (to a file)
  • import settings (from a file)

293QCAD (main)Feature RequestLowmulti-select for blocksAssigned
Task Description

It would be nice if one could select multiple blocks in the block list at once (holding ctrl or ctrl+shift). Main purpose would be to delete them if they are not needed anymore. If possible, the same applies to layers.

316QCAD (main)Feature RequestLowBlocks list and selected blockAssigned
1 Task Description

Wouldn’t it be nice, if selecting a block in model view would somehow highlight (just like clicking a block in the list does) the selected block in the “Block List” window?

(Feature request sounds a little harsh, enhancement proposal would seem more apt.)

355QCAD (main)Feature RequestLowRemember function for dimension OptionAssigned
Task Description

I think it would be nice to have more flexibility for Prefix etc. option (not only the drop down with a given choice) and a remember function for all those fields like postfix and tolerance.

Why Remember Function:
If I use a postfix like <>” in the postfix field I’m only able to use it for this particular dimension type at this time. If I change the type (from Horizontal to vertical or what ever) I have always to repeat my postfix. The same with tolerances.

384QCAD (main)Feature RequestLowMenu icons under Mac OS XAssigned
Task Description

Make this an option. Default should be no icons since icons are unusual for Mac OS X application menus.

396QCAD (main)Feature RequestLowBlocks: moving blocks: show bounding boxAssigned
Task Description

Blocks: moving complex blocks with drag and drop should show bounding box as preview

408QCAD (main)Feature RequestLowScript Macro recorderAssigned
3 Task Description

Having practically no experience in scripting, a recorder that one could activate to memorize repetitive tasks (ie: inserting several layers with different attributes when starting a new drawing)would a useful tool to help get a start on scripting.

426QCAD (main)Feature RequestLowScriptable entitiesAssigned
Task Description

Provide script functionality for entities:

  • Paint or decorate entity, for example based on custom properties assigned to the entity
  • Listen and react to events
454QCAD (main)Feature RequestLowcombined move/rotate/scale with two reference pointsAssigned
Task Description

It would be extremely helpful, if marked objects could be moved/rotated/scaled in a single step with two reference points as source and two reference poitns as destination. With a tool like this, “should match”-drawings could be merged easily.

455QCAD (main)Feature RequestLowlogical operations for polylinesAssigned
Task Description

A missing feature in my work are logical operations (combine, intersect, ..) for polylines

Draw some elements, select them, say combine. The result will be the outline of all elements.

512QCAD (main)Feature RequestLowModify stretch and Restrict orthoAssigned
1 Task Description

The modify stretch tool wants first and second corner, start and end point, then starts afresh. When I turn on restrict horizontally eg to align two points between start and end, the restriction sticks and I have to call restrict none, to be able to perform the next iteration, set the first corner then.

So, in the quest for a comfortable user interface, it was nice, if the modify stretch first/second corners parameter setting was not affected by current restrict/ortho etc. settings. Actually, that does not make any sense at all anyways, does it, a rectangle is defined by two degrees of freedom, isnt it?

514QCAD (main)Feature RequestLowPunktpestimmung Intersection manual muss immer wieder n...Assigned
Task Description

Zeichnen einer Linie (Line two points) mit Punktbestimmung.
Wähle ich für die Punktbestimmung z.B. “End” bleibe ich in diesem Modus bis ich etwas anderes wähle. Gut ;-)

Wähle ich für die Punktbestimmung “Intersection manual” muss ich dies für jeden Punkt immer wieder neu anwählen. Schlecht :-(

2 Task Description

To add the option to ‘print only’ selected area in a drawing.

519QCAD (main)Feature RequestLowPress tab to access first control in options tool barAssigned
Task Description


Apparently this was possible in QCAD 2 due to the default behavior of Qt.

525QCAD (main)Feature RequestLowchange the printed symbol of pointsAssigned
Task Description


in QCAD3 RC2 points were printed as crosses, in QCAD3 RC4 they are printed as (very little) points. I think this isn’t a bug but a feature. ;-)

It would be nice if one could change this behaviour / select the symbol of points.

528QCAD (main)Feature RequestLowFont Editing Assigned
Task Description

Dear Sir,
I have noticed that in QCAD 3 rc4 it is not possible to open and edit font files.
This feature exists in version 2.2 and is indispensable to people using not common languages.
For example the unicode font does not have all greek characters, so I have added a few of the missing ones by editing the unicode.cxf font with version 2.2.
I kindly ask the designers to consider enabling this capability again.
Thank you!

533QCAD (main)Feature RequestLowKopierendes/Ausschneidendes Rechteck (Kreis) Werkzeug ....Assigned
Task Description

In meiner Vergangenheit habe ich in anderen CAD Programmen mit folgendem Werkzeug gearbeitet was ich für Detailansichten, Bereinigungen oder ähnliches extrem Hilfreich empfand. Wäre schön wenn es so etwas auch in QCad gebe.

Werkzeug: Man zieht ein Rechteck (oder Kreis) über einen gezeichneten Bereich auf. Alles was innerhalb oder außerhalb des Rechtecks liegt wird kopiert/ausgeschnitten/gelöscht und auch direkt an den Linienkanten des auswählenden Rechtecks geschnitten.

Momentan kann ich ein Rechteck für Selektion bestimmen - muss aber dann nach einer Kopie alles manuell trimmen, löschen etc. um nur den gewünschten Rechteckinhalt zu bekommen ...

554QCAD (main)Feature RequestLowAuswahlbox sollte auch mit der Shift Taste Bereiche dem...Assigned
Task Description

Ziehe ich mit der Maus eine normale Auswahlbox kann ich Elemente markieren.
Möchte ich einzelne Bereiche wieder herausnehmen muss ich alle Elemente einzeln anklicken (mit gedrückter Shift Taste).
Ich kann zwar dies komfortabler gestalten mit der Select → (De -) Select Contour Funktion welche aber erst über das Menue aufgerufen werden muss.

So wie ich einzelne Elemente mit der Maus auswählen und mit der Shift-Maus Funktion deselektieren kann wäre es schön wenn die Shift Taste auch bei Auswahlbereichen direkt zum deselektieren eingesetzt werden könnte.

564QCAD (main)Feature RequestLowSettings organisation in levelAssigned
Task Description

As an old professional “documentation writer and user inteface designer” but IMHO, I’m not convinced that the “Application preferences” are correctly organised for ease of understanding and using them.
These settings are organised in 2 levels. Some of the first levels have their own settings (e.g. “Graphics view”) while most others don’t (e.g. “Load/save”). May I humbly ;-) suggest some consistency rules :
- no sub-level if there is only one subject
- no items on main level if there are already 1 or more sub-level(s).
For instance :
- sub-level “Default Dimension settings” under “Dimension” is the only sub-level : then move these items under main level “Dimension” and suppress the sub-level ;
- the items under “Graphics view” main level (with several sub-levels)could be in a sub-level named “General” ;
Actually, “Graphics view” main level is the only one which has both its own items and sub-levels ;-))) ?

586QCAD (main)Feature RequestLowFile open dialog with previewAssigned
Task Description

Since this is not supported by Qt anymore, this would likely have to be implemented from scratch.

588QCAD (main)Feature RequestLowBemaßung Prefix Dropdown mit eigenen Vorgaben erweitern...Assigned
Task Description

Es wäre Arbeitserleichternd wenn ich bei den Optionen für Bemaßungen (Prefix/Postfix) eigene Präferenzen speichern könnte so das diese in allen Zeichnungen von mir verfügbar wären.
Zudem wäre es wünschenswert dieses nicht nur bei den Prefix sondern auch bei den Postfix Angaben nutzen zu können was dann alle(?) Manipulationen erschlagen würde.

596QCAD (main)Feature RequestLowTool "Lengthen" mit "Total" erweitern oder ....Assigned
Task Description

Eine oft Hilfreiche Zeit/Klick sparende Erweiterung wäre eine “Total” Option bei dem “Lengthen” Tool.

Aktuell ist es mit dieser Funktion möglich ein Element zu verlängern oder zu verkürzen um den Amount X. Der Referenzpunkt (von welchem Ende) kann bestimmt werden.

Die Erweiterung die ich mir wünschen würde wäre auch ein “Total” um ein Element auf eine bestimmte Länge zu bringen ohne einen Taschenrechner benutzen zu müssen. Referenz (welches Ende oder Mitte) sollte (muss) dafür wählbar sein.

Die Funktion “Property editor” stellt bereits über die Geometry Eigenschaften die Möglichkeit zur Verfügung einen “Total” Wert zu manipulieren. Leider bin ich aber hierbei nicht in der Lage zu bestimmen welcher Element Referenzpunkt dafür benutzt werden soll. Könnte ich die Referenz wählen (welches Ende oder Mitte) wäre auch dies dann durchaus akzeptabel ;-)

1 Task Description

To add support for drawing tangents between ellipses.

601QCAD (main)Feature RequestLowFür Berechnungen neu zu erstellende Elemente Werte von ...Assigned
Task Description

Es wäre schön wenn ich Werte wie zum Beispiel Längen von Linien direkt abgreifen könnte um diese weiter in Berechnungen verwenden zu können.

Ich habe eine Linie konstruiert wobei sich eine Länge y ergeben hat.

Nun möchte ich eine Linie zeichnen die 5 mal y sein soll.

Linientool → Wert 5* eingeben und y durch Auswahl mit der Maus von dem vorhandenen Elements übernehmen.

Natürlich könnte ich die Geometrie Info benutzen um den Wert abzulesen oder auch über die Zwischenablage zu benutzen. Ein abgreifen mit der Maus wäre aber schneller, direkter und wahrscheinlich auch mit weniger Fehlern (Human error) verbunden. Wahrscheinlich auch genauer da QCad, denke ich, mit mehr Nachkommastellen rechnet, oder?

604QCAD (main)Feature RequestLowMeasure and record X,Y coordinates tool - add to info ...Assigned
Task Description

Feature request
See topic - http://www.ribbonsoft.com/rsforum/viewtopic.php?f=31&t=2015

Just a thought, but one that could be useful for machinists in particular - a measurement tool that can snap to a point as per usual, but then just displays the drawing coordinates in X and Y. This could be expanded to the dimensions tool set, so that you can click on a point and print the coordinates next to it.

609QCAD (main)Feature RequestLowClean up toolAssigned
1 Task Description

To have a ‘clean up ' tool to:

- eradicate duplicate lines
- eradicate stray points
- remove empty layers
- remove unused blocks
