Task Description

Text dialog (QTextEdit) strips tabs in toHtml.
If tabs can be retained, text entities could support tabs.

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.

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

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
1 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.


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

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
2- angle de coupe du haut
3- hauteur du cône
4- Ø bas
5- angle du bas

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.


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.

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”

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?

2140QCAD (main)SuggestionLowChanging navigation mode for mouse wheel doesn't change...Assigned
1 Task Description

Looks like error, but may be that’s feature request.

CAD software uses typical navigation behavior as:
Wheel = Zoom; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right.

Any other software like browsers, office software (openoffice writer, ms excel and so on), 2d paint software like GIMP (Photoshop and so on) uses other behavior:
Wheel = Scroll up/down; Ctrl+Wheel = Zoom; Shift+Wheel = Scroll left/right.

Users, that intensively use CAD and other software simultaneously prefer to make same behavior in their applications switching CAD scroll to plain mouse wheel.

QCAD’s “Application Preferences”: “Graphics View: Navigation”: “Mouse wheel/ two finger swipe”: “Scroll” allow user to assign scroll up/down to wheel mouse instead of Zoom. But there is mistake Ctrl+Wheel didn’t change to Zoom. Ctrl+Wheel continues to scroll up/down, as the wheel.
Wheel = Scroll up/down; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right. No zoom!

Draw manipulation at this mode like a hell: you need to use wheel in conjunction with Ctrl/Shift to point draw in desired position, than move your hand to +(-) for make desired zoom.

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, ...).

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. ;)

1954QCAD/CAMReleaseLowRevised PWM Post ProcessorAssigned

Hallo Andrew,

I have revised the PWM Post Processor to Revision D.

728QCAD (main)Performance IssueLowSlow loading of drawing with many block insertsAssigned
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.

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.

2063QCAD (main)Performance IssueLowBad performance while zooming inside layout block with ...Assigned
2 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!

1811QCAD (main)Feature RequestLowZoom 1:1Assigned
Task Description

It would be nice to be able to adjust the zoom factor so that the scale on the screen matches a ruler which I lay on the screen.


1506dxflibFeature RequestLowwriteVPort parametersAssigned
Task Description

637QCAD (main)Feature RequestLowViewports / View ListAssigned
Task Description

1. The Scrollbars for each window in the Viewports has the same size like the normal used scrollbars for windows. If you are working on a normal size Monitor it “steals” a lot of “working space”. Is there any possibility to make the scrollbars smaller or just a line to separate the windows so that I have to navigate with Keyboard and mouse?

2. I thing the Viewports and the View List belongs together - is it possible to get a button in the “View List / Tool Bar” to choose a Viewport style instead of “walking” the long way over the “Drawing preferences” Menu?

1999QCAD (main)Feature RequestLowViewport: Add additional properties for controlling dim...Assigned
1 Task Description

When working with multiple Viewports with different scale it could be very useful to have extra properties controlling how dimensions are rendered in the viewport:

E.g an extra “Dimension Scale” under “Scale” in the Viewport selection’s ‘Specific Properties’ section, could allow having the same size when printed.
This Dimension Scale would be multiplied on top of the Scale value, but only for Dimensions rendering.

Toggle button for hiding any dimensions in the Viewport. Maybe this should be controlled by being able to specify a Layer that should be hidden in this Viewport only, then I could select my Dimensions layer here.

The Viewport properties:

11 Task Description

UCS support.

724QCAD (main)Feature RequestLowUseless reference point entering when moving relativelyAssigned
Task Description

this is a usability feature request:

If you want to move an object relatively to any point (e.g. by entering @x;y in commandline) it does’nt make sense to enter a starting reference point. Of course this is possible by clicking to any location on the screen. But it’s difficult to change between mouse and keyboard so often.

It should be possible to enter a “don’t care” or “any” reference point by pressing a keyboard shortcut (e.g. enter like in AutoCAD).

821QCAD (main)Feature RequestLowUnderline text optionAssigned
Task Description

Feature request - to have an option to underline text.

779QCAD (main)Feature RequestLowTurning detailed view on/offAssigned
2 Task Description

My system: Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz and 8 GB of RAM and NVIDIA GT218 (GeForce 210)

For a normal drawing displaying it in all detail is a good thing and the performance of my quad-core system is more than adequate.

But I discovered (or rather experienced) that when putting a large collection of individual drawings of gears onto one big sheet (960 mm x 600 mm - preparation for laser cutting), the performance was so bad that I had to wait several seconds (>10 sec) for each step in the process of arranging all the parts on the layer.

Request: It would be a big help and performance booster if you could disable the detailed view of each part/layer and only draw a rectangle to visualize the outline of the part.

Please take this in consideration. Attached you find an example of how that could look like. (Actually when pasting a drawing from the clipboard you already do that.)

784QCAD (main)Feature RequestLowTurn text into hatched polylinesAssigned
2 Task Description

Would it be possible to add a feature which turns selected text into solid fill hatched polylines?

That would make it possible to migrate the drawing from one computer system to another without having to worry whether the used font is installed on both systems, like when sending a drawing to a manufacturer for laser engraving.

Right now I can do it by hand, letter by letter, and that is a rather labour-intensive task.

1983QCAD (main)Feature RequestLowTrim All or Bulk Break outAssigned
1 Task Description

This is a trim method I am missing in Qcad.

20 years ago it existed in CadKey.
You had a bunch of lines or segments.
You defined a (new) line or segment as cutter.
‘Trim All’.
You pointed at the side of the cutter entity to trim all intersecting at that side.

Pritty the same as in this topic:

Only in rare cases I can use Husky’s workaround as pro.
It all depends on what else is in the clipping rectangle that is needed to trim all intended.
If of no use all single crossing entities have to be chosen one by one.

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 ;-)

2091QCAD (main)Feature RequestLowToggle redrawing of hatches Assigned
2 Task Description

Because modifying hatches have lag issues I’d like to propose a toggle that turns of the redrawing/rendering of the hatch. Especially while modifying the hatch.

The hatches always have a boundary that can be worked with right? So when we move or stretch the hatch we can still see the boundary and its handles to perform all the actions.

This could be a new view mode that turns of the view of the interior/pattern of the hatch but leave the boundary of the hatch.
Or the draft mode can be extended to include simplified hatches while modifying.

1233QCAD (main)Feature RequestLowTab key to cycle between selected objectsAssigned
Task Description

I think it’s a useful adition and makes it easy to select objects that are overlapped. I know there is a selection filter, but sometimes this is faster and/or all the objects share the same type and such things.

If I remember correctly, Inkscape has this behaviour.
