1926QCAD (main)Feature RequestLowNo negative coordinate values ? (DO command)Assigned
1 Task Description

Just starting with QCAD, for some hours now - really excellent user interface (compared to other low budget CADs, like DCAD, or BeckerCAD...) !

Surprisingly, point coordinates - entered via the command line, and shown with correct positions on the drawing- are not displayed correctly with the ‘dimordinate’ (DO) command.
There are no negative values, even when the center point (0;0) is right in the middle of the drawing, so points left and below should have !


1928QCAD (main)Feature RequestLowOptionnally 'Auto clean up' after generation of NaN / N...Assigned
1 Task Description

Some functions / methods can generate some sort off entity or part with NaN / Null / Null-lenght ... props.
Some explicitly don’t and test their actions with isNull().

As these serve a purpose in some processes, trails of them can be part of the results.
For some users Null / Null-lenght are meaningfull, for other users these produce errors down the line.
In a few cases its a desirable feature eg. controlpoint spline.
(Allthough there are no Null props involved with equal successively controlpoints)

Many problem post on the forum are related to Null - Zero and so on.

In some cases it can’t be undone by re-editing the drawing.

If it can’t be undone by Undo/Redo it is a bug.

In some cases there is a difference noticed after file save-close-open.

1930QCAD (main)Feature RequestLowOption disable "Auto Zoom on load" for saved "Layout Vi...Assigned
Task Description


my setting for “Auto Zoom on load” is checked to on. That works perfect for me for most of my drawings.

But if I save a drawing with Layout Viewports then I have to adjust every Viewport again after loading.

Would it be possible to have an option below Application Preferences / Graphics View / Appearance / Auto Zoom on load / ON which excludes drawings saved with Layout Viewports?

1934QCAD (main)Feature RequestLowDiametric text - overlaidAssigned
Task Description

Diametric text is always placed above a horizontal measurement.

I often want to indicate both the inside and outside diameter of an object e.g. a wheel using diametric text. The text is overlaid and illegible.

To avoid text overlapping, I use Horizontal Aligned because I can control the position of the text to avoid illegible text.

A better method would be to alternate the placement of diametric text (alternatively) above and below a measurement so that in the majority of cases an overlap would be avoided.

Similarly for a vertical measurement, the text is overlaid and illegible.

When the angle is almost vertical, the angle controls the side the text appears however it also reverses the direction of the text (which is logical but not attractive).

Kind regards

1974QCAD (main)Bug ReportVery LowFile > Print Preview: Cannot move paper in new drawingUnconfirmed
Task Description

Yesterday I set up a Windows 64 bit install of QCAD Pro which shows the same bug I have been seeing for a while in the Community linux git repo.

Create a new drawing and then go to “Print preview”. Enable “Move paper postion”, the cursor changes to the hand icon, but the paper position is unable to be moved. Only by saving the drawing, exiting the program, restarting and reopening the drawing, will the “Move paper postion” function correctly.

Affected versions tested:

Windows 64bit installer download, as of yesterday.
Linux 64bit build from git, about 20minutes ago.

For what it’s worth, this bug is not present in this previous git checkout:

Version: (3.21.1)
Build Date:
Jul 2 2018

Qt Version:
gcc 6.3.1

Thanks for a great product.

1976QCAD (main)Feature RequestLowEnvelope at offset to a poly toolAssigned
Task Description


1977QCAD (main)Feature RequestLowCorresponding coordinate format Assigned
Task Description


It would be less confusing to read messages in the command line protocol if it would use the same coordinate separators like the settings below Application Preferences / General / Coordinate Format.

This example shows the “Absolute Cartesian Coordinate” but of course all corresponding format settings should be used within messages.

Absolute Cartesian Coordinate: Setting = semicolon (;) but the message will use division (/).

Task Description

It is hard work to do this manual input with meta characters.

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.


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:

2011QCAD Community EditionSuggestionLowUpdate 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.

1843QCAD/CAMBug ReportLowCreating ToolPath StallsAssigned
Task Description

Hi Andrew,

Still working with and on CAM HPGL for the HP7580 pen plotter.

I have added a penplotter test drawing, that might be used for testing en callibrating plotter and pens. You may add it to the Examples-directory.

QCAD has a lot of trouble creating toolpaths and exports. Much too often it shuts itself down, or gets stalled. Why? I am not sure.

1877QCAD/CAMFeature RequestLowPost Processor TutorialAssigned
Task Description

Hallo Andrew,

I am still busy on the never ending G-code story. Doing so I wrote a small Post Processor Tutorial for all those nerds who wants to write their own. If you like it you might add it to QCAD. However, since English is not my native tongue I suggest checking it would be wise.

Meanwhile I have downloaded the source code, and could not find the CAM’s Drill-path-script. I am now using a negative Drill Cut Depth to set a Laser Dwell time, were as a field “Dwell Time (in seconds)” in the Drill-path would be more appropiate. Is this script open source available or is it part of ‘closed part’ of QCAD?

Hallo Andrew,

testing the drill toolpath I used single point markers.

In 3D simulation the tool drills the toolpath AND uses the drill as a mill.

1997QCAD/CAMBug ReportLowCan't export gcode, intermittentlyAssigned
Task Description

When I create a simple drawing, I cannot export the gcode until I restart qcad.

general steps to reproduce the issue:
1. open a new drawing
2. Add a letter “D” near the origin in Arial font, about 7mm tall.
3. explode it
4. save the drawing
5. Fill in in the “cam configuration” 6. Select the drawing and generate the tool paths.
7. Hit the “export button” or the menu item.
8. Observe that you see the “camexport” command appears in the command section, but there is no file generated for the gcode.

If you restart qcad, then the gcode will export as expected. Also, it appears to work for more complicated drawings. I had the same issue, when I tried to generate the same thing, but using the string “November 2019” at 5mm height. I am using up to date MX Linux with kernel version 4.19.0. I also observed this behavior under Windows 10 professional.
