1903QCAD (main)Feature RequestLowSaving layer settings, e.g. visibility status, associat...Assigned
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.

1911QCAD/CAMFeature RequestLowDrill ToolpathAssigned
Task Description

Hallo Andrew

It would be more than conveniant, defining the drilling locations of the drill toolpath, by selecting a circle’s center point.

Task Description

Hallo Andrew,

Testing the drill toolpath I find it hard to select the correct tool by a small bug

1913QCAD/CAMBug ReportLow3D Simulation Behaves oddAssigned
Task Description

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.

Cam Export and generated G-code is not effected.

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

1916QCAD (main)Bug ReportLowMoving an object in an angled viewport with mouse does ...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 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

1917QCAD (main)Feature RequestLowAutomatic labels with static information of the drawingAssigned
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”.

Task Description

It would be nice if QCAD spit some kind of warning message when trying to render a layer with a name that doesn’t exist (and perhaps render nothing), rather than silently rendering an empty image. :D

1923QCAD (main)Bug ReportVery LowFaulty rendering Polylines with Global/Local Widths and...Assigned
Task Description

Win7pro 32bit Qcad 3.23.0

The Arc segments of Polylines with Global or any Local Width render faulty where Global Z or any of the arc’s local Z is not zero.

In the attached drawing setting the Global Z of the inner poly to 5,10,...

The setting of Z to not zero affects the radius of the projected arc and not the bulging of the poly.
It also affects the projected widths of the line inversely, but not by changing the widths properties.

Pritty rare combination! True.
Qcad is 2D native! True.

Flatten will resolve this.

It is not a purely visual rendering fault, the poly will explode as such.

Maybe similar flaw as with uneven scaling blocks with arcs.


1924QCAD (main)Bug ReportLowSweepAngle = 0Assigned
Task Description

Win7pro 32bit Wininstaller Qcadpro 3.23.0

Draw an arc.
Select the arc.
In Property Editor:
Set start angle to 135
Set end angle to 135

SweepAngle = */-360

edit the end angle and add “+360”, hit enter

SweepAngle = 0

An arc with zero sweep is a point.
A point is not an arc.
With the same start and end parameter an arc should have a sweep of +/-360.
As for entries by points or by angles.


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?

1933QCAD (main)Bug ReportLowAdvanced SVG export file overwrite check doesn't use up...Assigned
Task Description

In the Advance SVG Export dialog, when I edit the filename to be different than the default file that already exists and then clear the checkbox for “Overwrite existing file without asking” just to make sure that I haven’t already created a file with the modified name as well, then I get a popup warning that the export would overwrite the default filename, not the name as edited. In other words, the overwrite check ignored the fact that I edited the filename.

Observed on MacOS Mojave (10.14), but probably applies to all.

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

1936QCAD (main)Bug ReportLowver 3.23 not saving font informationAssigned
Task Description

The attached file is not saving font preference.
All fonts on the online layer are reported as the standard font. If I highlight one or all of the text entities and change the font to something like Yu gothic light, the property page reports yu gothic light and the screen reflects the changed font.
If I save, close and reload, the fonts for all text is again “standard”.

So then I try to enter new text via the “A” draw text command icon. I select “Broadway.ttf” as the main font in the text entry dialog.
One word “Broadway” is entered as the text. it appears on the upper left of the screen as expected and the font name is Broadway in the property editor. If I look at the dxf file source there is a whole bunch of text styles.
I save and close the file, and then open it again. Now the word Broadway has changed to font name “standard” in the property editor and is very definitely not the Broadway.ttf font.

I am not the originator of the file, I am just trying to change the font. If I start a new file and enter new text the font saves just fine, so I am thinking it is a setting somewhere, but I am unable to find it.

We (me and my customers) use these files for engraving so exact font is critical.

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 (/).

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.


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.

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:

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.
