QCAD Bugtracker

I’ve opened an existing, old dwg file in the Professional Trial edition, file(1) says it’s “DWG AutoDesk AutoCAD 2004/2005/2006”.
It contains (among other stuff) a floor plan with areas in m^2. A PDF export (from the original software used at the time, probably autocad) shows that this was displayed correctly.
However, in QCAD, I get a “\A1” and a very small number 2 instead. I’ll attach screenshots.

I see the following problem:
When I open a particular DXF file in the Professional Trial version 3.27.9.0 on macOS, “^I” in text fields is expanded to whitespace.
When I open the same DXF file in the Community Edition 3.27.9.0 on NetBSD/x86_64 (installed from pkgsrc), “^I” in text fields is visible as “^I”.

There are not a lot of waterjet resources so I went ahead an tried to modify mygcode.js.

The issue is that plunge rate is entered in the tool and that shows up in the toolpath. The water jet wants to see that number to determine how long it holds in place to pierce the work. It needs it to be displayed as a prefix “S” followed by time in seconds and finally a period. I had been just hard coding a 2 second default time as I only cut glass but recently found some circumstance where I need different vaules. It is also more user friendly to get it to work correctly.

 	[// variables: Change Plunge Rate prefix from F to S
   	 //                   			 name,                  ID,                     always, prefix, decimals, options
		this.registerVariable("plungeRate",          "FP",                   true, "S", 0);

It needs to show up in the header as M1407 = [FP] which the water jet uses as a default pierce time after forced stop. In this instance it looks like M1407 = S2. This is working in the code currently.

For each remaining toolpath the Waterjet needs a pierce time.

M3
M8
G [FP].

And this is were it falls apart. I have red lined the gcode in a word document highlighting the first few problem instances. The first instance displays the value for Feed Rate and not Plunge Rate.

<CODE>: SELECT ALL

M3
M8
G4 S240.  Wrong value, should be as above "S2." but instead it grabbed the feed rate value from toolpath 1 "240"

3. Save
4. Reload

It would be great if QCAD could create an arc tangent to another entity without necessity to type a radius.
Just two simple steps:
1. Click the endpoint of another entity to start the arc. The arc is tangent to the starting entity.
2. Click the second point to place the arc.

Andrew,
For more detailed description please refer to:
https://www.qcad.org/rsforum/viewtopic.php?f=33&p=40081#p40081

In the included screen grab below, left is when drawn cubic, closed periodic, from 4 points.
Right is when the file is re-loaded.

It is hard to select the incorrect shape when pointing near it ... Probably it is referring to the correct internal shape.
After drawing it explodes to a Null length polyline with 2 identical vertices.

I can’t include the error in a file as it reverts on re-load.

The same issue exist for quadratic, closed periodic, from 3 points.

Instead of having to click on the toolbar, it would be useful to have a keyboard shortcut for undoing the last fit point (or control point) while drawing splines. Preferably it would also be nice to allow the user the ability to set what the keyboard shortcut is for this function.

A block with Attributes can’t be flipped (Option bar) horizontally. The Attributes will be rotated 180° instead of been mirrored. Other entities in the block flip correctly.
Same block flipped vertically works as expected (Mirrored Attributes).
Same block flipped with FH or MI works as expected. (Mirrored Attributes).

Currently, the model space can display lineweights at scale 1:1
It’s very convenient when drawing small objects that will be printed at scale 1:1 : it makes it easy to anticipate the final aspect of the printed drawing.
But this feature is unusable for architects or users who draw large objects.

Therefore, it would be very useful to have a factor to multiply lineweight display in model space.
For example : if i know my drawing will probably be printed at scale 1:50, i set the value of the lineweight factor to 50.
Then every line would be displayed 50x thicker in model space.

I would like the ability to extend dimension lines beyond the extension line when using tick marks. Images are attached and posted here: https://qcad.org/rsforum/viewtopic.php?f=31&t=9785

Andrew,

Most probably not related to OS or QCAD version.

When hatching an area with Hatch from Segments (HS) there might be false positive warnings on open loops.
It seems that this is related to the orientation of the indicated segments and the order of selection.
The real problematic position is not always the first that is reported.
Loop count is increased even if it is a single loop.

Included a basic test drawing to replicate these.
Further details to replicate the issue are in the file.

Regards,
CVH

Case description: “Hatch from Segments” (HS) detects correctly an open loop but fails then to set the circle marker for an easy visuelle identification.

Same scenario tested with “Hatch from Selection” (HA) ...
... everything works like a charm

e.g: If I use content out of the clipboard to insert it multiple times into the drawing with using the Middle Manual snap [SN] the snap can’t be locked [SQ] and I have to reactivated the snap again and again for every following insert.
Other snaps like END or CENTER work flawless in this scenario.

Andrew,

Usually I point to something to start with.
Sometimes I want to point away from here but then the arrow is where I just clicked.

An option on creation would be nice.
The capability to reverse the Leader orientation afterwards is another method to get it pointing the intended way.

A Leader entity is stored similar as a polyline.
I think it would not be difficult to reverse the basic polyline and update the dimension shape accordingly.

CVH

Andrew,

When we use Lengthen/Shorten (LE) with a positive amount the result is clearly visible when indicating a side of an entity.
With a negative amount there is seemingly no preview.
It is generated and shown but one can not distinguish it especially with solid lines.

Adding an orthogonal auxiliary preview shape some N pixels long would do the trick.

Regards,
CVH

Andrew,

Unrelated to OS or QCAD version.

In the postprocessor configuration dialog there is a group box called ‘GroupCustom’.
One can add custom widgets to that, rename it and so on.

Such is not provided in CamProfileToolpathDialog.ui or CamDrillToolpathDialog.ui

It should be possible but we aren’t really able to mix up things with the ‘Message’ QLabel ...
A reserved QGroupBox would do the trick.

Andrew,

When switching from Default to Dark mode the text on alternating rows is hardly visible.
We can customize this color.

It would be easier if a proper default color is set on switching to and back.

Perhaps the user preferences can be remembered.
Perhaps only when the contrast would be affected.

CVH

Andrew,

I can’t find any documentation concerning OffsetBothSides under Misc .. Modify.
It is not listed in the QCAD features nor in the changelog.

There was a Feature Request FS#1130 for this, I think you might want to close that as being implemented.

The tool asks for a Line, Arc, Circle, Ellipse, Spline or Polyline.
It also seems to act on shapes that can be exploded to such entities like Text, Dimension and Hatch entities.

There may be many ‘Result loop not closed’ or ‘No offsets possible’ warnings when hovering over entities on a drawing.
The preview may be partially, one or two sided and even two sided partially and closed with semi-circles.

I only successfully created a dual offset for open Splines, open or logically open Polylines.
All other attempts result in a single offset at the indicated side.

There are the usual exceptions for Polylines with arc-segments but that is related to small arc segments and being tangentially connected.
Only tested it on a Win7 platform.
I don’t suspect that version 3.27.8 includes a fix for that ...

Regards,
CVH

When using SVG export on a drawing with a block defined, the export is incorrect. Arcs are drawn incorrectly and parts of the block are missing. If that block is exploded, the SVG export is correct. Attached is a block on the lower left and the same block on the lower right after explode. Also attached is the resulting SVG file.
This is not always the case. Some blocks are correctly exported to SVG. The upper row is again a block on the left and the same block exploded on the right. It exports properly.

I’m using QCAD Community Edition 3.27.7 on Windows 11.

When I started my drawing, I was able to change the size scale factor of (existing) dimensions using “Edit/Drawing Preferences/Dimension/Dimension Settings/Size scale factor”. However, suddenly this feature stopped working and now I cannot switch the dimension scale factor any longer.

I used this feature to be able to adapt the scale factor of the dimensions when printing in different scales.
I.e. all my drawings are in “original” size but when it comes to printing, I print some parts in scale 1:2 (in which case I used to set the size scale factor of the dimensions to 2) and some parts in scale 1:10 (in which case I used to set the scale factor of the dimensions to 10). Using this procedure, the dimensions have the same size (font size, arrow size, gaps etc.) on both drawings.

I have attached the drawing, that shows the described issues.

Autosave currently updates the backup file indefinitely regardless of whether the drawing has been modified since the last autosave. Request only update autosave following additional edits since last autosave.

The attached example file is written with a third party CAD program in R15.
Opened in QCAD CE all Dim/Label information are available.
If I load this drawing in QCAD Pro the Dim/Label information are lost.

If I load and save the example drawing with CE the newly written dxf is readable in Pro without any issue.

The dark theme for Linux is broken:

- Some icons have dark background (expected) and black foreground color (that should be replaced by white of very light gray)
- Some icons have light background (not cohesive with the theme).
- The command history shows dark blue font on dark gray background.
- The grid’s ruler shows black font over dark background for the numbers.
- The icons folder is missing in the GitHub repository, but other themes have that folder.
- The general icons (open, save, and so on) are not dark theme friendly. A better approach for maybe all the themes would be to use something like the breeze icons pack for LibreOffice, and it will have the added benefit of making the app look more modern.

The icons issue is the biggest problem. They should probably replace the black color for white or very light gray. Even the red accent color is not ideal for dark themes, is not the main issue.

Attached is an image that show the problems and another that shows LibreOffice with the Dark Breeze theme for reference.

Yes I’m aware that the U.S. survey foot has to be discontinuing December, 31, 22. However - as we’ve learned in the past it takes decades until a unit will disappears for good.

As the layout block contains the drawing sheet, the number, the viewports, it’s the presentable part of the drawing.

Maybe QCAD could be able to save on the dxf the “last state” of the drawing. If I saved on the Model and closed, it would open on Model... and if my last save was on the Layout”n”, it would open on Layout “n”.

At least on my work area, when opening a finished drawing, it’s the ideal for it to be opened in a Layout (if it was the active block while saving).

QCAD Professional 3.27.6.0 running on macOS 12.4 (21F79)

QCAD sometimes crashes when I am adding or removing items from toolbars. It isn’t consistent and I haven’t seen a pattern about which items trigger the crash. It has happened while editing different files, but I’ve attached attached a very simple example and two crash reports

dwg2svg supports exporting the layer name (and probably others?) as namespaced XML attributes (`qs:layer`) which works well.
However I’d like to export block attributes as well, as seen on the following screenshot:

https://imgur.com/a/wUd0adE

(...so `ROOM_NAME` would become `qs:ROOM_NAME=”Eötvös terem”` on the respective XML element).

Thanks in advance.

When editing an existing toolpath to update the parameters of the selected tool, we can update the Feed Rate and the Plunge Rate, but I couldn’t find any way to update the Spindle Speed.

Even when using the Edit Tool KE button, we can edit parameters of the tool on concern but none of the modification is applied to the current Toolpath because as I see, tools parameters are copied fron tools definitions to a Toolpath only at creation of this Toolpath, but Toolpath are not updated accordingly.

Could you please add an edit field for Spindle Speed in the CAM Profile Toolpath window?

Many thanks’, and best regards.

Andrew,

Not OS or Version depending.

We can’t filter on some specific properties of polylines.

Handy would be:
- Global Width
- Orientation

Specific:
- Polyline Pattern
But I don’t really search for them ... For some post-op I just need them all to be set to ‘No’.
- # of vertices
Filtering the complex from the more simple ones.
- Including Bulges or not
To seperate polylines with arc segments form others.
There some operations that don’t really work with bulging.
- Z values and/or global Z
This would make sense for some but filtering on Z is not common under QCAD as it is 2D.

Regards,
CVH

Andrew,

Changing orientation of a polyline with RV or by changing it in the Property Editor clears the global width value.

Single line pieces as polyline default to CCW.
Still the global width is cleared when trying to set them CW.

I didn’t update since 3.27.0 but reading this topic I suppose it still is valid.

Hello,

I’ve quite often the task to transfer changes from one set of drawings to another (similar) set.
My ideal setup would be to open one set in one window and the other set in another window.
Both windows would be arranged side-by-side (larger monitor).
Changes would be copy-pasted from one set to the other.

From #2352 I’ve learned that there is a command-line option to achieve this.

Unfortunately it’s not possible to copy-paste between these instances.

And yes, it’s important to do this in two windows to see both versions at the same time.
So, tabs are not the answer.

It’s also ok if i could detach a tab from one instance and arrange it aside of the main window (like the property editor).
Than all data transfers would happen inside the same instance.

Best regards,
Klaus

Would it be possible to add Qcad’s theme folder to the local shared path, for example this would be /home/username/.local/share/QCAD/QCAD/themes for Linux. I know this works well for line types and would be extremely helpful for themes.

Could we please implement the ability to display file contents in the file explorer. This would make it easier to decide which files to open.

How to reproduce the bug:
1-open a new file
2-select text tool, simple text(one line,no formatting) and alignment in base-left
3-write some text in somewhere position in the draw, repeat this in others positions
4-save the file in .dxf R15 [2000/LT2000] (dxflib) format
5-close Qcad
6-open the saved file, the writhed text lose original position and now all the text have 0,0 position

The tool “Clip to rectangle” / “Cut at Area Boundary” tool used on an area with lines and arcs will partly complete arcs to circles.

It might be useful to have the possibility to manage the references of the images contained within the drawing. A design could use recurring images, stored in a folder outside the one in which the design is located. Moving the drawing or folders (or changing the PC) will lose the folder references and the images are not displayed when the drawing is opened again.
I imagine the possibility to view the references of the images (and if necessary modify manually or with a pointer) with the option of: attach, detach, reload, etc., as in the example below (referred to ActCad - based on Intellicad technology)

Referring to Layer List / Block List: It would improve the workflow if the Delete key on the keyboard would be linked to the minus icon (Delete). The command ER is also ignored in both list.

It would be nice to have the possibility to select multiple blocks with Shift and/or CTRL + mouse like the Layer List to use a delete etc command on all selected blocks at once.

QCAD (before version 3.27?) used to show some custom XDATA, e.g. tag 1000, even for application names that are not “QCAD”, which for me was useful, so it’s somewhat of a regression. (I think it was broken when selecting multiple items, maybe that’s why it was removed.)

I suggest to bring that feature back, but maybe show it only when a single element is selected if that’s easier.

(As a workaround/hack I guess it would be possible to rewrite the required information as QCAD compatible XDATA externally I guess.)

As per https://qcad.org/rsforum/viewtopic.php?f=32&t=9089, I suggest to extend the distance information tools:

* show Delta Z (at least when any of the elements has Z information)
* allow switching between 2D and 3D distance
* maybe allow to show both
* maybe change the text to distinguish between them (”Distance” → “Distance 2D/3D”)

“em” just always goes back to the main drawing. But for nested blocks, when jumping from edit mode of one block to the next nested block, it would be helpful to have some “ep” to go back to the previous block.

This was discussed at the forums...

Currently if I position one Tab (KT) to stacked profiles QCADCAM will use it on ALL in Z matching profiles. Practically in most cases would be to use tabs only on the lowest profile.

It would be nice to have some kind of control on which profile a tab has to be used.

Minor issue!
When using keyboard to initiate the dropdown menus.
I noticed the ALT “D” does not cycle through the headings Draw & Dimension in the same way.
ALT “M” cycles though Modify & Misc or ALT “S” cycles though Select & Snap.

dwg loaded in 3.27.1 frees QCAD (no response) and a Win10 PC. Same drawing loaded in 3.26.0 causes no problems. It looks to me that two hatches (handle 198b6, 198ba) are the culprits.
Drawing saved without those hatches opens without any problem in 3.27.1.

It would be helpful if the scale field that appears while placing a viewport would also re-appear when the viewport is selected after it’s already been placed in the layout. It would also be helpful if the pre-populated values in the dropdown matched those in the global layout scale field.
