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 !


 1927 QCAD (main)Bug ReportLow Drawing and printing inconsistent, with wrong/missing e ...Closed

Drawing and PrintPreview are consistent, but printout differs : rectangle missing (bottom right), line missing (bottom green line) - see att. Error can be reproduced, after saves and restores.
A VERY elementary WYSIWIG-problem....

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.

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:

 1076 QCAD/CAMBug ReportHigh Crash on Mac OS X when using internal Trackpad Closed
1 Task Description


I have just updated my Mac OS from 10.9.2 to 10.9.4. QCAD 3.6.2 seems to be working normally under the newest version of Mac OS, but has developed a very specific bug which leads to reproducible crashes when a text object is edited.

Steps to minimally reproduce:
1. Open QCAD
2. Create a text object
3. Place the text object on the canvas
4. double-click the text object and edit its contents
5. click OK to accept changes
6. repeat from step 4 three or four times.

After several attempts to edit a text object, QCAD will crash with EXC_BAD_ACCESS (SIGBUS) in thread 0 (QCoreApplication).
The crash can also be triggered by moving the text object around on the canvas (instead of editing its contents).
The bug does not require anything else (no other objects on the canvas, no particular font, occurs in both new and previously saved documents).

Apart from this bug, QCAD seems to work fine on OS X 10.9. The text editing crash did not occur before the latest OS update. No other applications on my system seem to be having any problems. If this problem can be fixed, I think QCAD will be quite usable on 10.9.

 1089 QCAD/CAMBug ReportLow Convert polyline from segments on locked layers deletes ...Closed
1 Task Description

If you select (line) segments in a visible yet locked layer and choose “convert segments to polyline” (OG), the segments are deleted, but inserting the polyline fails.
So you can easily destroy locked layers by mistake which contradicts the idea of locking layers.

 1142 QCAD/CAMFeature RequestLow Distance Entry in "Feet and Inches" Closed
1 Task Description

I use architectural units everyday in QCAD and would appreciate being able to enter feet and inches from the “command line” for convenience and accuracy.

I have been entering “calculations” to arrive at the distance values (i.e. 10*12+6.125 = 10’-6 1/8”), but this method is time consuming and prone to input error.

I would like to see Acad’s architectural distance method implemented in QCAD. This entry method would replace the “calculated” entry with (as an example): 10’6-1/8.

Command Line: Next point: 10’6-1/8
The <’> mark triggers a 12 times multiplier for the proceeding number,
the next number is the whole inches and
the ↔ is a separator that adds the fraction to the whole inches before it.

Thanks for considering this feature request. I’m certain that many QCAD users in the Architectural, Mechanical, Electrical and Construction professions wold appreciate this convenience (especially those moving past Acad).

 1716 TranslationBug ReportLow Wrong plural forms in translations Closed
1 Task Description

I found that words which has plural forms are translated in manner where only two forms are possible - like in English language. For example: “Object” and “Objects”. But other languages (for example Polish) very often have more than 2 plural forms.
There are also strings which use only one form (for example: “Reset label position of %1 dimension(s).”) but cardinal number placed in string point on more forms than one.
All these strings looks bad when translated and sometimes even in English. I mark most of them using comments:




I believe problem can be fixed using plural form strings: https://www.gnu.org/software/gettext/manual/html_node/Plural-forms.html

 886 BookBug ReportLow Wrong coordinates in the Orthographic Projections hands ...Closed
Task Description

I have the book dating about a year back, with the following metadata (no other version information in there):

Producer:       FPDF 1.7
CreationDate:   Fri Aug 24 15:10:36 2012

I believe there is a slight error in the Orthographic Projections hands-on (it may not be there in current versions of the book, but since my download timeframe is long over, I can not check that – should that be the case, sorry for the noise).

On page 219, step 1 of the exercise (drawing the front view), it is said

Set the first corner of the rectangle at the origin of the drawing (1)
and the other corner at 30,20 (2).

On pages 225-226, steps 7 and 8, drawing a 45-degree auxiliary line for the right-side view, it is said

Set the position of the line at the origin of the drawing (coordinate 0/0).

0/0 is the “bottom left” corner of the top view. The correct coordinates for the auxiliary line’s position are 0/30, the “bottom left” corner of the front view.

(I had not realized the bug tracker had a Book category as well – hence this is a duplicate of an e-mail report I have sent to [email protected])

 642 DocumentationBug ReportLow Better explanaton for Layer '0' Closed
Task Description

Layer ‘0’ has some special function. E.g. it can not be deleted, it will contain the data of undeleted layers.

I recommend adding some explanations: Explain the function of Layer ‘0’ as third paragraph in chapter 12 of the manual. Further it should be recommended to never use this layer for drawing.

By the way: I consider this to be better than no layer undelete. BUT: is there really not way for a true layer undelete...

 1004 DocumentationBug ReportLow QCAD e-book not searchable in Preview, Acrobat Closed
Task Description

I just downloaded QCAD and bought the doc that goes with it. Lo and behold, I find that I cannot search the doc in Preview (Acrorbat Reader too!)! So I paid extra for doc that might be argued should come with a product (although its hard to complain about the price) and then I cannot even search it electronically? There is just everything wrong with that in the year 2014! Please fix as it is extremely inefficient and time consuming to not have electronic search capability.

 1040 DocumentationBug ReportLow Break out Manual on Circle/Ellipse does not respect Rem ...Closed
Task Description

3.4.7 trial as well as community Git 9d3979

  • Draw a circle
  • B2
  • Make sure “Remove segment” is ticked
  • Select circle, then select two points to break out in between


  • Segment gets removed (not really, but read on)


  • Segment does not get removed, but circle is indeed broken into two arcs

Same for an ellipse.

I can see that by selecting two points on a closed circular shape it’s nigh impossible to tell which segment the user actually wants to remove :)

The documentation doesn’t mention this corner case. For clarity, a note detailing this effect a bit should be added to the docs.

On a slightly related note, I do not see why the feature couldn’t work on Polyline objects as well (with the same corner case restriction if it’s a closed polyline).

Very useful feature btw, thanks for it.

 1889 DocumentationBug ReportLow Autosave fails for QCAD original cxf font location Closed
Task Description

Now I try the third time to post this .... :-( .... deleted by “wrong token”???????
However ...

Regarding to the online tutorial:

Opening a CXF Font for Editing

To load an existing CXF font file in QCAD to view and edit its glyphs, simply use the menu File > Open and choose the format filter “CXF Font Files (*.cxf)”. Then choose the font file you want to open. The fonts that come with QCAD are stored in directory “fonts” of your QCAD installation.

quote end

Editing the cxf font in the original QCAD font folder will lead to a error message triggered by the Autosave function:

File access error: “C:/Program Files/qcad-3.22.1-pro-win64/fonts\~~Husky_test_font.dxf”. Access is denied.
[15:34:58] Autosave failed: C:\Program Files\qcad-3.22.1-pro-win64\fonts\~Husky_test_font.dxf

Note: Windows will not save anything in a system folder and the process is terminated by windows.

Solution: Move the cxf font for editing from the QCAD folder to a unprotected folder like Documents/drawings.
After editing is done move it back to the QCAD font folder.
