Create hatch
Set origin point of hatch pattern to custom coordinate
Save
Load

Hatch offset parameters are unchanged but visual appearance has changed

Copy block reference in drawing with one unit (e.g. Inch).
Paste into drawing with other unit (e.g. Millimeter) using a rotation while pasting.

See:
https://www.qcad.org/rsforum/viewtopic.php?f=107&t=4593&p=17839#p17835

To improve the flow of drawing I’d like to switch off the dialog for the rotate tool. Most of the times i use the interactive input and delete the original. So I don’t need to click a popup to acknowledge that.
I allready use the same option for the move/copy tool.

Shortcuts do work except G,Y (and maybe other I don’t know of)

see https://www.qcad.org/rsforum/viewtopic.php?f=32&t=4842

I have set the delete layer preference to make the next layer in the list the current. This will not work for sublayers. After deleting a sublayer the 0 layer will become current.

It woul be really handy if there is an option to set the reference point of the copy selection.
Maybe this can be added to the clipboard widget?

I use a font that changes the characters of latin and greek to technical symbols.
http://www.fontspace.com/micronus/y145m-2009 The font is installed and working okee.
But in the text tool → special characters button → others I expect to see this modified character map but instead I see the standard unicode characters.
When I use a gtk tool gucharmap I can see the character map as expected.
Now it is really combersome to enter the special characters.

Stretching multiple points of an entity is not possible to my knowledge. I
can use the stretch tool but this gives me a rectangular selection box and
this limits my posibilities. For example when entities are over eachother.
I hope that in the future this will become more like blender. With a freedraw
selection tool and/or shift clicking multiple nodes.

In print preview mode I click the button for drawing preferences.
I go to Printing: Page and change the offset for x,y in the viewport.
Then apply but the page has not moved and the autozoom still redirects to the old position.
When I redraw the window through the window manager or quit and reopen the printpreview the page has moved to it spot.

Deleted (undone) block attributes are stored to DXF/DWG.

Blocks disappear (or their content does) after creating again with the same name. In attached file:

1) Created cirle
2) Select circle, BC, select center, name is ‘testblock’ 3) Repeat 2) – circle is now gone

QCAD/CAM version 3.16.7.1 (snapshot release)

QCAD/CAM version 3.16.7.1 for Ubuntu Linux starts up with a totally black screen with only the title bar showing. By clicking around at the top of the screen I can get the menus to drop down and appear over the blank black screen. That is how I captured all the version information below. QCAD/CAM version: 3.15.5.0 for Ubuntu Linux starts with all the normal screen graphics appearing normally. I labeled this bug report as critical because QCAD/CAM is unusable on Ubuntu Linux, but for me it is not so critical since I can use the Windows version.

Qt menu heuristic causes Edit > Drawing Preferences to disappear with French locale under macOS.

Edit > Application Preferences and Help > About are moved to erroneous locations as well.

Font substitutions broken for many cases.
Font “Standard” can never be substituted.

DWG archive opened by QCAD (15.X/16.X - Linux mint 18.1 and Windows 10) does not show traits that represent project windows, when the same file is opened by the dwg True view they appear, follows archive for evaluation.

Zero length lines are not shown in QCAD. For best compatibility these should be shown as dots.

This is not the only menu that didn’t work properly: moving the mouse cursor on the lower arrow made the list moving up; but is impossible to make the list moving down when I put the mouse over the upper arrow.
The only workaround (time consuming but effective) is to select the first upper paper size: selecting again the menu I can see tha current selection in the second position: I select the one above it; and so on, until I find what I need.

Hi friends,

I have this traceback with my Qcad from ppa for linux, to export in png image:
Warning: libpng warning: Image width is zero in IHDR
Warning: libpng warning: Image height is zero in IHDR
libpng error: Invalid IHDR data

Impossible to obtain an png image, and others too. I am on Linux Mint Serena 64B alias Ubuntu Xenial 16.04. Qcad last release:

Version :
3.16.4.4 (3.16.4.4)
Internet :
QCAD.org
Date de fabrication :
Jan 26 2017
Révision :

Qt Version :
4.8.7
Architecture :
x86_64
Compiler :
gcc 5.4.0

Files imported from other CAD applications might contain blocks that are mirrored if the block reference uses an inverted extrusion direction.

Block attributes are not properly synchronized on QCad 3.16.5 after editing the block in the drawing, in Linux Mint 18.1 and in Windows 10; On Windows as less frequency, the error is intermittent, on Linux is constant. Attach the dxf to test.

I have many .dxf files created in QCad-2.2.2.0 (which I still use) all of which open in LibreCad without issues.

If I try to open a file in the version below (or an earlier fairly recent version) the file chooser dialog is empty.

Version: 3.16.5.0 (3.16.5)
Build Date: Feb 20 2017
Qt Version: 5.6.2
Architecture: x86_64
Compiler: gcc 5.4.0
OS: Mageia 6 x86_64 with plasma5 D.E

However if I copy a file name from the same directory using Dolphin file manager and paste it into the filename field in the chooser (which is showing no files) the file opens up correctly.

I reported this in Mageia bugzilla here against an earlier version but there was no response as I think the maintainer is MIA. https://bugs.mageia.org/show_bug.cgi?id=18816

Today I decided to try the latest version in the hope that this issue would be fixed (I am also a packager with Mageia) but it is still the same.

I will add the build log as an attachment in case you see something that may be specific to our configuration.

It would be good if we could resolve this before the imminent release of Mageia 6 ;)

Running from CLI I see these around the time I open the file chooser dialog:

A curious fact is occurring here QCad 3.16.5 is aborting the opening of files in 90% of the attempts on a machine with native Linux Mint 18.1 and works normally in a virtual machine under Virtualbox in Windows 10, tests were done on the 3 machines (VM-Linux, Nat-Linux and Win 10) with QCad 3.15.5 and everything works normally. The two notebooks tested have Intel I-7 RAM = 8Gb Ram and 4 processors. Follow 02 files for evaluation.

This is an interesting bug on my machine. The attached file crashes on 3.15.5, works perfectly well on 3.11.0 and 3.7.5

To see the problem open the file and click on the upper spline. QCAD disappears.

Draw > Line > Parallel
- switch type to Line, XLine or Ray
- switch back to Auto
- Parallel is always line segment

hi,

I miss one Offset option to use an offset indirectly related to the used entity. Right now I have to work with further construction lines and trim, divide, delete etc. tools to archive what I need.
Basically an offset as a ray would be enough but unfortunately we have no control of the Ray orientation.
This said - it would be nice to have an infinitive line added to the “Offset Polyline Segment” option to be able to use an Offset as construction line which is not only reflecting the shape of the source.

ich habe ein Linien Gitter in QCAD erstellt und dann mit CAM Export eine NC Datei erstellt.
Im CAM Simulator sieht man dass der GCODE Postprozessor nicht den kürzesten Weg verwendet.
Anbei folgende Dateien :
CAM_TEST_LINIEN.dxf, CAM_TEST_LINIEN.nc, CAM_TEST_LINIEN.log und eine Bilddatei CAM_TEST_LINIEN.png hier kann man sehen wie die Eistellungen für die GCODE Erstellung sind.

QCAD crashes when you perform the following operations:

1. Create Polyline with just one segment.  
2. Delete the node with DELETE NODE(S) command.  
3. Press ESC several times.
(-> QCAD crashes..)

Since the launcher batch no longer requests “-style plastique” QT wants to apply the native style of the desktop environment. This fails on a headless system (or where the current user has no graphical shell to connect to) with the message “Gtk-WARNING **: cannot open display: “. Fortunately, QT provides a workaround in addtion to the new “platform=offscreen” flag.

In the tools that set -no-gui, beforehand export these variables into the environment

export QT_STYLE_OVERRIDE=""
export QT_QPA_PLATFORM=offscreen
export DISPLAY=""

PS: QT-offscreen will not find fonts; unfortunately the workaround only allows for a single directory to search them (I need helvetica):

export QT_QPA_FONTDIR="/usr/local/share/fonts/type1"

Maybe that should get reported upstream, so that like LD_LIBRARY_PATH several directories could be specified.

I can not print and I can not export to “pdf” file.
I use the latest professional version of Qcad with windows 10.
Thank you

Please attached file. When dragging a selection window across only the cyan lines -I get only one line selected?

Trying to create map tiles using dwg2maptiles with a transparent background by adding the option-
-background=’#00FFFFFF’
-background=’transparent’

The output has transparent background but the PNGs get multiplied and scrambled and are not at all as expected.

Attached: original DWG file and an example of the error prone PNG.

Given is a drawing of two concentric arcs connected at the ends. (see attached drawing Circle_from_3_Tangents_1.png)

When I try to add a circle at one end by the “Circle from 3 Tangents”-tool, it does nothing.

I also tried it with another drawing (see attached drawing Circle_from_3_Tangents_2.png) - same negative result.

I then tried drawing Circle_from_3_Tangents_3.png. Here the tool only produces outside circles and misses the inside ones.

Hope you can confirm my findings.

... for the Option bar.

@ sign cannot be entered into command line on German keyboards on which Alt-Q has to be pressed to enter @.

This is a Qt/Linux bug which interprets Alt-Q as part of a shortcut starting with Q.

Workaround: change shortcut of Reset tool from QQ to something else, not starting with Q.

- Draw circle inside other circle
- Draw > Hatch > Hatch from Segments
- Click both circles
- Right-click

I tried to hatch an area and the Reference Manual said all entities can be used but it doesn’t works at my example. Did I missed something?

The test drawing shows at the top the goal with exploded polylines. At the bottom I have rectangles (Polylines, drawn with the Rectangle tool) what is unfortunately not working.

Offset curve not trimmed / clipped correctly.

Offset distance: 2.5

- Create spline from fit points
- Rotate spline
- Spline shape changes due to erroneous start/end tangents

Similar problem when reversing spline from fit points.

Rulers show only whole numbers.

Hello

In the Print Preview or Drawing Preferences / Page Settings if I select a Custom size, then landscape/portrait does not really make sense.

For instance, at work we have a laser cutter which uses a printer driver. The bed of the laser is 600 wide by 300 high. When I wanted to cut
something, I created a custom page size of 600×300 and selected Landscape (because it is wider than high)

Strangely, back in the Print Preview, the page is now sized opposite with regards to Portrait / Landscape mode, which was confusing somewhat.

(see pictures attached)

I think that for ‘Custom’ page size in Drawing Preferences, the option of Portrait or Landscape should probably be ghosted

Then, I think that for Portrait / Landscape mode in the Print Preview, it should display the shape most appropriate, rather than just assuming that the document fits the norm:

1. Taller than Wide for Portrait mode
2. Wider than Tall for Landscape mode

Occurs when breaking out segment from closed polyline with more than two intersecting entities.

This also affects the hatch from segments tool when used with closed polylines.

Example:
https://raw.githubusercontent.com/qcad/qcad/master/scripts/Modify/BreakOut/Tests/data/closed_polyline.dxf

The startup script still forces a QT-style; Getting bored of that one, qcad runs fine with the system default style - probably that was a qt4 thing, that can be removed, so it blends better with the DE?

The copied attribute is now associated with the first block reference instead of the second.
