The Application Preference setting “Graphics View - Appearance - Prevent white-on-white/black-on-black display” seems to be a global setting that doesn’t take the draw order into account. For example: With the setting enabled, it prevents creating a white hatch of a higher draw order on top of a larger, colored hatch with lower draw order (background). The preference does not seem to evaluate if the object is truly drawn as “white-on-white”.

With the preference enabled, setting the object color as “white” will set the “white” color label, but the object color actually stays black. Its hard to determine why it happens in that case.

Is it possible to let the global preference setting be applied to objects after evaluation of the draw order, and determine if the object actually is a true case of white-on-white?

My workaround: Disable the preference setting (I think it is default = on), and only enable it for ad-hoc checks of hidden and overlooked objects.

I use CTRL + I to pull up drawing preferences. Upon changing the dimension settings quickly and closing it normally by pressing enter it closes. But if i go to the next tab (drawing tab) then press enter to load it up quickly instead of pressing CTRL + I. Upon changing the dimensions settings and pressing enter to close it, it won’t close but instead flash and i have to keep pressing enter and eventually it closes.

I think this is a bug.

I have the Pro Version

1) Line with command prompt in Command Line widget is missing padding/margin - letter C is glued to frame.
2) In the “Selection Filter” widget there is an “whitespace” character before colon “:” symbol on multiple places, it doesn’t seem repeat anywhere else

Andrew,

In the attached dxf:
Besides that it is clear that duplicate vectors are not filtered ...
Where a segment is crossing in another node a non valid node is returned as self-intersection point.
Seems to be unrelated to CW/CCW or tolerance.

Where 2 nodes coexists 4 duplicate vectors are returned.

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.

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

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.

CVH

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.

1. Create spline
2. Move spline nodes. After ~10 times move qcad is crashed with backtrace:

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.

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.

Building with the bundled version, 1.8.5, works fine.

When I try to build using the system version, which for Mageia Cauldron is 1.9.3, the build fails.

https://raw.githubusercontent.com/kekePower/mmbl/master/qcad/2019/12/11/20%3A13%3A48/log.qcad

Here is the current spec file for version 3.23.0.4.
https://svnweb.mageia.org/packages/cauldron/qcad/current/SPECS/qcad.spec?revision=1465894&view=markup

It looks like qcad is incompatible with versions above 1.8.5.

Are there plans to port to the new version?

Thanks in advance.

How to reproduce.

1. Create a text field with some non-english words in the upper index. (see attached pic1.png)
2. Save the project and close QCAD.
3. Run QCAD and open same project.
4. Now upper/lower indexed text becomes not human readable UTF codes. (see attached pic2.png)

Tried different fonts - doesn’t help.

Hi Andrew,

Creating G-code for cnc-laser, the laser-tool can not be correctly set at all.

Attached a laser tool proposal

Add SPx; with x being pen number from 1-8.

TODO:
- Which color corresponds to which pen number?
- What if there are more than 8 colors in a DXF files?

Hi Andrew,

Still working with and on CAM HPGL for the HP7580 pen plotter.

I have added a penplotter test drawing, that might be used for testing en callibrating plotter and pens. You may add it to the Examples-directory.

QCAD has a lot of trouble creating toolpaths and exports. Much too often it shuts itself down, or gets stalled. Why? I am not sure.

Hi Andrew

QCAD/CAM misses a hpgl.plt import. If gerber and G-code can, so should plt.

Hi Andrew

A request for adding some fields to the toolpath

Hi Andrew,

Still working on creating HPGL.PLT toolpaths for the HP7580 pen plotter. QCAD has some trouble creating toolpaths. Too often it shuts itself down, or the PC gets stalled.

Recreating the same error however is possible

Hallo Andrew,

I am still busy on the never ending G-code story. Doing so I wrote a small Post Processor Tutorial for all those nerds who wants to write their own. If you like it you might add it to QCAD. However, since English is not my native tongue I suggest checking it would be wise.

Meanwhile I have downloaded the source code, and could not find the CAM’s Drill-path-script. I am now using a negative Drill Cut Depth to set a Laser Dwell time, were as a field “Dwell Time (in seconds)” in the Drill-path would be more appropiate. Is this script open source available or is it part of ‘closed part’ of QCAD?

Hallo Andrew,

Still busy on the never ending G-code story. Urgently needed the very common Traverse Toolpath.

Example added as pdf.

Greetings

Hallo Andrew,

Still busy on the never ending G-code story. Urgently needed the very handy G-code Block Toolpath. This ‘toolpath’ also solves a lot of “editing requests”.

Hallo Andrew

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

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.

Add a program description to the CAM configuration dialog and export to postprocessors as variable.

Hallo Andrew,

I have revised the PWM Post Processor to Revision D.

Hallo Andrew,

Found a bug in the 3D Simulator execution

With a Mac (and no external mouse) there’s no middle button so it’s not possible to pan the 3D view (that’s what they tell me in the forum). It would be useful if one could use command-drag or control-drag to pan around the 3D view.

Hello dear CAM developers!

I need to use the same tool at different spindle speed in a single machining file.
I would deeply appreciate if you could add a Spindle Speed edit field in the CAM Profile Toolpath edit window in order that each Toolpath can have its own Spindle Speed value (same as you did for Feed Rate and Plunge Rate)

FYI, the tool on my concern is a laser who’s power is driven by the Spindle Speed PWM signal.
I need to be able to do both engraving and cutting in a single file.
Alas! this laser tool is defined with a fix and unique number (99).
Therefore I cannot define different laser tools with different speeds.

Many thanks
Best regards.

I’m often in the situation that I have to select for nesting 50+ sheets. Currently is only a Shift + left mouse click selection possible. It would be nice if QCAD/CAM could get for the nesting / sheet selection additional a mouse rectangle area selection.

The inside corners of profile tool paths have rounded inside corners. This occurs because the rounded outside the bit cannot make it all the way into the corner of the feature. Think of tracing the inside wall of a cardboard box with a can of soup. The can makes direct contact with the box walls, but its
round shape is unable to completely fit into the tight corners— there’s always a gap.

In a dog-bone overcut (see the figure in attachment), the inside profile corner is enlarged into a semicircle, allowing the sharp edges of the mating piece to slide through without interference.

When a dog bone is applied to the inside corners, as shown in the second figure in the attachment, the joints fit together nicely!

The following website explains what should be implemented More elegant CNC dogbones

There are two ways to implement this tool. Either you modify the original design (as implemented in Fusion 360) or you can do it at the moment you define the tool path (Estlcam allows you to do this for example). See the feature Corner overcut, on Estlcam website

Please refer to: https://www.qcad.org/rsforum/viewtopic.php?f=74&t=9033

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.

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,

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.
