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


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.

1368QCAD (main)SuggestionLowContext Menu - suggestionsAssigned
1 Task Description

I love using the context menu, speeding up my workflow indeed.

I would like to suggest that we have the added option to show only icons if desired and also that maybe an option to save and show commonly used tools!

Maybe the context menu could be configurable to show two columns, one for the normal last used tools and the othjer one for the user saved tools?

What do you think?

1469QCAD (main)SuggestionLowCartouche automatiqueAssigned
1 Task Description

Would not it be possible to create a kind of template for printing?
We draw our room without cartridge. The cartridge will automatically appear when printed. The scaling could be automatic so that it goes in the A4 and therefore also will post the scale automatically. The name of the play could be the file name, date last saved after it the rest of the information that would be to add somehow (material index, designer, ...).

Original suggestion:


Ne serait il pas possible de créer une sorte de template lors de l’impression ?
On dessine notre pièce sans cartouche. Le cartouche s’affiche automatiquement lors de son impression. La mise à l’échelle pourrais être automatique pour que ca rentre dans le A4 et donc l’échelle s’afficherai aussi en automatique. Le nom de la pièce pourrais être le nom du fichier, la date du dernier enregistrement après c’est le reste des infos qui serait à ajouter je ne sais comment (matière, indice, dessinateur, ...).

1526QCAD (main)SuggestionLowExporting block attributes to CSVAssigned
1 Task Description

Two useful commands make it necessary to

1-”delete all the history of the command lines without terminating QCad” ; and

2-”export attributes to the CSV file as exported to the Blocks List”

1678QCAD (main)SuggestionLowProperty Editor dialogAssigned
Task Description

The line for “General properties”, “Layer” the line is too narrow,
so you do not see the layer name when the Property Editor is pinned to the side.

1754QCAD (main)SuggestionLowWhen Selecting multiple blocks that contain the same at...Assigned
Task Description

When selecting multiple blocks that contain the same attribute names, attribute properties appear with the values of the last selected block instead of “various”. I do not know if this is a “bug” or developer option, but “various” would be better in my opinion.

1789QCAD (main)SuggestionLowApplication Preferences / General / Performance :0Assigned
1 Task Description

Hi Andrew,

we know that you need to have always software performance in your mind to decide which features / tools can / should be implemented and on which way.

I really appreciate your effort to find the best middle way between software features and performance but I think also it’s a tough call to appraise worldwide the overall customer equipment to make the software workable to the best for everybody. That isn’t possible without compromise.

Maybe it would make sense to think about a new dialog in the “Application Preferences” to let the user decide what kind of feature are absolutely needed regarding to his/her work-task / equipment. I don’t mean that you need to cover every single thing but the main “performance jeopardy’s” should be covered with an on/off switch.

Yes I know - that isn’t done in 5 minutes but I think that can make your life easier in the long run and will cover even more customer.

Just my two cents. ;)

1851QCAD (main)SuggestionLowLateral surface of a coneAssigned
Task Description

Module mise à plat d’un cone


Serait il possible dans un futur d’ajouter un module de mise en plan de cone.

Une petite fenêtre sur lequel on donne par exemple :
1- Ø haut

1915QCAD (main)SuggestionLowViewport does not rotate view-port when changed in pape...Assigned
Task Description

To reproduce

1. Select a new view-port in model-space
2. Select the appropriate paper-space
3. When the paper space opens change the angle of the viewport.


The object in the viewport changes but the viewport itself remains unchanged


That both the view-port and the object changes angle as the angle is updated


If you abort the placement (but keep the angle) and go back to model-space and then redo the operation the view-port is rotated along the angle. It seems that the viewport only picks up the initial angle once the paper-space is open and ignores any changes thereafter


1. Select the view-port per normal in model-space
2. Open the paper-space and set the wanted angle but do not place the view-port in paper space
3. Abort the placement on paper-space and redo the whole operation

Once the paper space is opened again the view-port will have the chosen angle

2072QCAD (main)SuggestionLowInserted and flipped block mirrors text and dimAssigned
Task Description

Text and/or DIM used in blocks will be mirrored if inserted with a vertical/horizontal flip option.

Text/DIM which was successfully used in previos QCAD versions are now mirrored if they are loaded in the current version.

Version 3.23.0 doesn’t shows this behavior.


2115QCAD (main)SuggestionLowMove toolbars with negative positions to 0 positions Assigned
Task Description

As it can be seen in the attached image, QCAD toolbars may dock to a position slightly outside the visible area of the screen. After having docked there, I have not been able to move them any more. Their current position is just in the middle of the screen.

The position of the toolbars remains the same after the deinstallation of QCAD, shutting down, restarting the computer and reinstalling QCAD. I kindly ask for help.

Kind regards

2011QCAD Community EditionSuggestionVery LowUpdate QCAD CE SpatialIndex module to latest versionAssigned
Task Description

Building with the bundled version, 1.8.5, works fine.

When I try to build using the system version, which for Mageia Cauldron is 1.9.3, the build fails.


Here is the current spec file for version

It looks like qcad is incompatible with versions above 1.8.5.

Are there plans to port to the new version?

Thanks in advance.

2126QCAD (main)SuggestionVery LowPE casts on individual hatch segmentsAssigned
Task Description

QCADpro / win7pro 32 bit / 4GB / 1e generation i7 2.6Ghz / HDD GeForce GT 520

The method PE casts the clipboard on individual hatch segments.
Hatches should be considered as a single complex entity not allowing certain actions.

Not that it matters: In doing so the scaling is off too.


1954QCAD/CAMReleaseLowRevised PWM Post ProcessorAssigned
Task Description

Hallo Andrew,

I have revised the PWM Post Processor to Revision D.

1 Task Description

Slow loading of drawing with huge number of block inserts (more than 10000).

1801QCAD (main)Performance IssueLowlow perfomance in paper space and viewportsAssigned
Task Description

Improving the performance of the exceptional use of the processors when switching from the model to the paper space (testing with the attached file) the functionalities of the commands for the viewports are too low in the paper space.

2063QCAD (main)Performance IssueLowBad performance while zooming inside layout block with ...Assigned
1 Task Description

Zooming in and out is lagging to the point of unusable. This is happening in a layout block with the cursor pointing inside geometry with hatches. When the cursor is pointing outside the geometry zooming works as expected.
The attached file has a very simplified testcase that shows this problem almost in the same way as a more complex drawing with multiple layers and hatches.

edit: I also attached the more complex drawing because it is a bit unclear to me where the lagging stops. Outside the viewport or outside the paper.

I just noticed the selection box has the same problem!

2021QCAD (main)Performance IssueVery LowCannot work with big dwg filesAssigned
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.

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.

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

455QCAD (main)Feature RequestLowlogical operations for polylinesAssigned

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 :-(

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.

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

Perhaps with an initial dialog which allows the user to choose what they want to clean up.
