Under OS X 10.9.4 I often experiencing a crash with QCad-Pro 3.6.3 when using the mirror tool. It’s repeatable to roughly 90% , just do it a few times and it will crash.

In this report I have included the crash trace from OS X as well as a simple example DXF file (a house gate) which can be used to repeat the crash. Just do a vertical mirroring a few times and the crash will happen.

It usually happens more if you choose “Keep original”

While not quite a showstopper I would consider this something that really needs fixing ASAP as it could mean data loss (which happened to me).

 2086 QCAD BugtrackerQCAD (main)Bug ReportLow Font formatting in text dialog ClosedJohan Persson Task Description

QCadPro (snapshot, but can be reproduced with 3.24.3 as well)

OS: MacOS 10.14.6
Version: (
Build Date: Jun 3 2020
Revision: 828df3a
Qt Version: 5.13.2
Architecture: x86_64
Compiler: Clang 10.0.0

To reproduce:
1. Add some text to a drawing
2. Double click on the text to open the text-edit dialogue
3. Select all text, change font, press OK

Expected behavior: The font has been updated

Actual behavior: The font seems to visually change in the edit box but as soon as you press OK to close the dialogue the text on the drawing is not changed. Viewing the text with the font information (via properties) it can be seen that the embedded font information has not been updated.

- Select text and edit the properties

QCadPro - MacOS Mojave (10.14.6)

Version: (3.24.3)
Build Date: Mar 16 2020
Revision: 6e718a8
Qt Version: 5.13.2
Architecture: x86_64
Compiler: Clang 10.0.0

In the attached .dxf file is a simple drawing (a wooden deck). In the layout space (of A3 size) there are two viewports (one of the frames and one with the decking).

In the left viewport a spurious enlarged part of the block “stolpe” (eng. column) has appeared in the exported PDF (not visible in either the layout nor the model space). See attached .PDF where it is clearly visible.

So it seems that the interaction of blocks with viewport triggers a bug.

2018QCAD BugtrackerQCAD (main)Feature RequestLowLayer visibility setting per view/view-portAssigned5Johan Persson Task Description

In a medium complex drawing it’s often too much details to have all layers in a drawing visible at once. Also, it is of great importance to be able to have a single model to avoid duplication of work and risk inconsistency.

So i would like to create a number of views where each view has selected layers visible (that makes sense for the purpose of the view) and then assign the views to different layout blocks (using view-ports) in paper-space to be able to setup printing of several views on the same page/PDF

This also means that view-ports would have to be aware of what view they are displaying (if any besides the standard-view).
This will then make it possible for printouts of different views with selected layers visible (different for each view and view-port) and still have only one model. Today this is not possible.

As it is today the only limited workaround is to set the layers you want to display, print/PDF of that viewport on separate page, and then change it for the next page, and so on. The big drawback is that you cannot have two different views/view-ports on the same page with different layers visible. Also, for large drawing it is painful to have to do a lot of manual setup for each rendering of the complete drawing.

1917QCAD BugtrackerQCAD (main)Feature RequestLowAutomatic labels with static information of the drawingAssignedJohan Persson Task Description

I would like static information of the drawing (like scale, creation-date, modified-date, revision etc) to be available as automatic labels to be placed in the drawing (with selectable style, font etc)

This would greatly simplify the creatin of title sections in the drawing and making sure it is consistent with the actual drawing and not requiring manual “synchronization”.

1916QCAD BugtrackerQCAD (main)Bug ReportLowMoving an object in an angled viewport with mouse does ...AssignedJohan Persson 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 to 90 degrees
4. Place view-port in paper space
5. Select the view-port in paper-space by clicking it
6. Try to move the object itself in the view-port (by clicking the “top” dot) to the right by moving the mouse to the right while holding the left mouse-button.


The object in the viewport moves down vertically NOT to the right


The object moves to the right

(It seems mouse movement does not compensate for the rotated angle of the viewport)


None, except compensate for the angle in your head and moving the mouse the “wrong” way when correcting the placement of objects in the view-port

1915QCAD BugtrackerQCAD (main)SuggestionLowViewport does not rotate view-port when changed in pape...AssignedJohan Persson 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

1903QCAD BugtrackerQCAD (main)Feature RequestLowSaving layer settings, e.g. visibility status, associat...Assigned1Johan Persson Task Description

In a medium complex drawing it may be too much details to have all layers in a drawing visible at once.

Instead a number of views would be created that saves not only zoom level and position but also what layers are visible and not (as appropriate for the purpose of that particular view). This is very cumbersome (to the extent it is not really realistic) to achieve today and requires a lot of duplication of both model and layers.

The advantage of adding this is the ability to have only one model (with multiple views) and avoid duplication of work and the risk of inconsistency inherent with many copies of the model.

As a further (and natural extension to this) would be the ability to used this functionality with view-ports to be able to create (possibly many) paper-spaces from a single model. This would however require view-ports to be aware of what view they are a window into. A single change in the model would then propagate to all defined view-ports and paper-spaces.

 1796 QCAD BugtrackerQCAD (main)Bug ReportLow File > Open Recent: crash when file is in Google Drive  ...ClosedJohan Persson Task Description

When a file is opened from “File→Open Recent” on QCad Pro it gives a 100% repeatable crash if the file is on a folder synchronized with Google Drive. If the file is opened using “File→Open” instead it works as expected. See attached crash-log.

OSX specific. Does not happen on Linux with synchronized Google Drive folder

 1792 QCAD BugtrackerQCAD (main)Bug ReportLow Dimension > Angular: transformations broken Closed2Johan Persson Task Description

(I originally described the problem in the forum: )
(The problem was also reproduced by user “Husky” so it not installation specific.)

I have a model where one of the details is as shown in attachment 1

However, when I create a viewport and display the part in the the layout the angular measurement is another. See attachment 2.

In the model it should be noted that the part displayed is a detail copied with a different scale as to Zoom in on a detail in order to put dimensions on it. It was created by copying a part of the model and pasting it back in the model but with 3x zoom.

I have also included the full .dxf file in the hope that it helps you both reproduce and fix this issue

Note: The same problem seems to also produce “ghostlines” in other viewports in the layout which is not present in the model. Removing the angular measurement also removed the ghostline. You can observe the issue by looking at layout2 and you can see a line (dimension layer) going from top right corner of the viewport towards the lower left. This line is not present in the model and appears to be some strange extension to the angular dimension the detail that is just to the top right in the model.

It would be nice if the OS X Pro version could support the standard OS X full screen pattern in the same way as native OS X applications.

With this I mean that applications in full screen will create a temporary new desktop as long as they are in full screen mode.
