Andrew,

In some cases Draw > Ellipse > Inscribed in Quadrilateral (EQ) may return a perfectly healthy result but rotated for 90 degrees.
- Size doesn’t matter.
- Quadrant doesn’t matter.
- Geometrical open or closed base shape doesn’t matter.
- A mirrored base shape usually preforms well.

See attachment with examples.
The incorrect results (red) are rotated 90 degrees around the ellipse center (dotted)
Green is a correct result from a mirrored base shape.

On macOS 14.1 and QCAD 3.28.2, the state of the OS (light or dark theme) affects some of the QCAD colour palette for the life of the session. So far I’ve noticed the problem with the keyboard shortcuts in tooltips and text in the command line output, but there may be other instances of the problem.

To reproduce:

1. Set the OS to light mode.

2. Start QCAD. Note the keyboard shortcuts in the tooltips are optimised for a light palette.

3. With QCAD still running, switch the OS to dark mode.

4. Note that while most of the QCAD interface switches to a dark mode palette, the keyboard shortcuts in the tooltips do not.

A similar behaviour is observed when starting from dark mode and switching to light mode.

I hope that makes sense. See attached screenshots for examples.

I display different fonts in three different CAD software. QCAD displays incorrectly (text display width is incorrect). The attachment is three different CAD display effects. The red mark is where QCAD displays errors.

Qcad alters color of adjacent text, if certain unicode characters are used.

MacOS Sonoma, 14.1.1. MBP M1. / 3.28.2

When using SV / RO commands and using the checkbox to ‘use the mouse’ for scaling / rotating, then that setting is not retained at the next use. So every time the command is executed, a mouse move to check the box must be performed.

I can not add or remove Points to existing Spline

Printing / PDF export with crop marks enabled fails with Qt 6 packages macOS on M1/M2/M3.

Hi, I’m new in QCAD.

I need to print some drawings amd the decimal separator is a ‘?’ instead of ‘.’.

Mi versión is QCAD 3.28.2.0, revision a8039fc, Qt version 5.13.2, architecture x86_64, and the OS is Windows 10.

How can I solve this?

Thanks

Using XCODE15, QCAD fails to compile. The error shown:

In file included from include/spatialindex/SpatialIndex.h:251:
include/spatialindex/MovingRegion.h:155:34: error: no template named ‘binary_function’ in namespace ‘std’; did you mean ‘__binary_function’?

Per Apple’s website, binary_function are no longer provided in C++17 and newer

As explained in this forum post.... https://www.qcad.org/rsforum/viewtopic.php?f=30&t=10520

File > New from template does not show the dialog and shows a spinning wheel instead.

From the looks of it the cursor image data is read at a wider pace as it is stored.
One can distinguish the double cross positioning QCAD cursor but it is shifted.

Exception in CAM simulation when previewing tool position.

When screen-based linetypes are enabled, the zoom box width depends on the zoom level and can get very wide / thin.

Context menu of dimension text label line edit widgets offers a <> entry which does not insert <>.

Label position is only reset on reload / entity regeneration.

Affected tools: Insert Bitmap (keep proportions), Rotate (by mouse), Scale (by mouse).

If nesting preference “Place small parts into holes of other parts” is disabled there may be fewer solutions or no solution if rotations is set to 1.

When using PDF Export I see different lineweight to using dwg2pdf. See Different lineweights PDF Export vs dwg2pdf

Hi,

tested with back_plate.dxf (QCAD Tutorial Example)

Drawing is original mm, metric, A4. Printprewiew works, Autofit Drawing to page etc. works as expected!

In Drawing Preferences: Changed settings to inch, imperial, Ansi A
Printpreview works but options like
“Autofit Drawing to page” and “Autofit pages to drawing” are not working as usual ...

Went back to mm etc - everything works again as expected.

The option “true scale” has no effect, projected result does not use true scale.

Clicking “Set to Printer Margins” has no effect.

I’m seeing only a partial hatch in the shape. See here for details.

The last version (3.29.4) present a very important issue.
When we work with a “complicated” file (about >1MB or up see attachment test.dwg) the cursor and selected object not work fine after move some layout windows in Paper_Space: disappear coordinates informations and snap nodes. (see attachment before.png an after.png)
This issue is present in all Qcad version (Linux, Mac-intel, Mac-silicon, Windows).
The last working-fine version is 3.28.2
I’m a enthusiastic Qcad user and I hop that this issue will be fixed early!

Andrew,

It seems that Attribute Definitions are created by default with Invisible = Yes
I can’t control this property on creation.
I can select the newly created Attribute Definition and toggle the flag.

Consequence when not updating this flag for each new Attribute Definition is that inserted Block Attributes disappear on synchronizing.
See attached files.

The default Invisible = Yes setting is not retained on save/reload.
(You will probably discover these flags to be ‘No’ in the attached files)
Synchronizing after a reload has no longer the mentioned consequence.

On inserting a Block Reference based on a Block with Attribute Definitions the Invisible flag of new Block Attributes is always ‘No’.
InsertBlock.js nor InsertBlockItem.js consider the Attribute Definition Invisible flag status when creating and inserting a new RAttributeEntity object.
e.g.: InsertBlock.js L184-L206

IMHO:
- Invisible = Yes on creation is not the best default for new Attribute Definitions.
- Not retaining this flag on save/reload is probably not intended.
- Disregarding the Attribute Definitions Invisible flag on block insertion seems incorrect.

Scale value is not loaded from drawing and shown as 1:1 if the scale is stored as a number.

1) Start with a new fresh drawing
2) draw an object (e.g. Circle)
3) select Layer>Duplicate Layer
4) Proposed name “0 Kopie” is ok, and maybe change color
5) New Layer “0 Kopie” is created but no objects in this copied layer.
6) Select original layer and select Modify>Detection>Detect Duplicates
=⇒ there you find the copy of your layer content twice

Greetings,
I am a user of Alibre Design. When I export the dxf or dwg from alibre the dimensions are shown outside the sheet models.
I tried with different 2D CADs and only QCad and LibreCad give me this type of error.
Is this something known? Do I need to attach more files to understand the problem?
Thanks for your attention,
Greetings,
Francesco Ricci

Steps to reproduce
1. create entity
2. select entity
3. property editor, change color to a custom color
4. deselect entity
5. select entity
6. in property editor, choose custom color

Andrew,

Usage states:
“Default is to explode everything into points, lines, arcs and circles”

In this Forum Topic 10358 you explain to use an exclusion list:
“dwgexplode is geared towards exploding everything. You’d have to provide a list of all entity types that are acceptable (i.e. don’t need to be exploded)”

Your example list includes the entity type ‘Splines’.
Marking splines entities as acceptable or not contradicts that they are never exploded.

But in the code itself is stated:
“explode texts to splines, arcs, lines”

TTF text is indeed exploded in mostly splines and some arcs or lines if that is appropriate.

All depends on the intended behavior ...

Post all kind of layout issues for the book “CAD Instruction” here, e.g. overlapping text.

when changing the window focus, the paper in the print preview disappears and doesn’t come back anymore

Move cursor near spline, e.g. when drawing line with auto snap active.

Custom text height cannot be set (enter closes the dialog, tab does not activate the entered text height)

Open

Postponed

Done

Changing the unit of a drawing can make QCAD hangs

• Mile: QCAD hangs in endless loop
• Nanometer, Microinch: view turns white, at some levels of zoom, it turns gray
• Foot, Yard: GraphicsView grid too small meshed

Autosave

Make interval configurable
Enable / disable
Path (?)

• draw → line → snap coordinate
• draw → line → snap polar coordinate

'setButton'"Set"

problem: the option tool bar isn’t show at all

• a script would be great actually. then we can generate different drawings with different units / scales / paper settings
• OdWriteEx from OpenDesign creates something similar: a bunch of rectangles, each with a text label and an entity inside, e.g. “Aligned Dimension” and below a rectangle with an aligned dimension inside

• the example drawings should contain:
  • an instance of every supported entity type (line, arc, circle, all dimensions, block insert, text, hatch, solid fill, ...)
  • lines in all available widths
  • lines in all available types
  • lines in all available (fixed) colors and some custom colors

• script should be able to generate example drawings for different:
  • units
  • drawing scales
  • paper sizes
  • paper settings (background color, multi page settings, etc.)

• File “ExampleDrawings/data/dim_aligned.dwg”:
  • upper limit: 0.01, lower limit 0.02 → correctly shown
• choose “Generate Example Drawings” → the element “aligned dimension” (with limits set) shows 0.010.01 now, since both label and tolerance limits are set (according to the property editor):
  • label: <>\S0.01^0.02;
  • upper limit: 0.01
• same for lower limit
• “Generate Example Drawings” inserts the drawings as blocks

cannot hatch single full ellipse

1. open the attached drawing
2. select the polyline
3. fill it with hatch pattern “stars” → looks ok, the whole area is filled
4. save the file
5. re-open it
6. there is a gap in the filling now, see attached screen shot

Change the user manual directory / file names from ‘simpletextviewer’ to
‘qcad_user_manual’ and adjust the sources accordingly that the manual can be shown
in the help menu.

We can simply drop the contents of the manual that is checked in and replace
it with a simple note “No manual is available yet for this technology preview of QCAD 3”

1. new file
2. insert (drag-n-drop or insert button) from library browser → segfault
