1923QCAD (main)Bug ReportVery LowFaulty rendering Polylines with Global/Local Widths and...Assigned
Task Description

Win7pro 32bit Qcad 3.23.0

The Arc segments of Polylines with Global or any Local Width render faulty where Global Z or any of the arc’s local Z is not zero.

In the attached drawing setting the Global Z of the inner poly to 5,10,...

The setting of Z to not zero affects the radius of the projected arc and not the bulging of the poly.
It also affects the projected widths of the line inversely, but not by changing the widths properties.

Pritty rare combination! True.
Qcad is 2D native! True.

Flatten will resolve this.

It is not a purely visual rendering fault, the poly will explode as such.

Maybe similar flaw as with uneven scaling blocks with arcs.


1924QCAD (main)Bug ReportLowSweepAngle = 0Assigned
Task Description

Win7pro 32bit Wininstaller Qcadpro 3.23.0

Draw an arc.
Select the arc.
In Property Editor:
Set start angle to 135
Set end angle to 135

SweepAngle = */-360

edit the end angle and add “+360”, hit enter

SweepAngle = 0

An arc with zero sweep is a point.
A point is not an arc.
With the same start and end parameter an arc should have a sweep of +/-360.
As for entries by points or by angles.


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 !


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.

1930QCAD (main)Feature RequestLowOption disable "Auto Zoom on load" for saved "Layout Vi...Assigned
Task Description


my setting for “Auto Zoom on load” is checked to on. That works perfect for me for most of my drawings.

But if I save a drawing with Layout Viewports then I have to adjust every Viewport again after loading.

Would it be possible to have an option below Application Preferences / Graphics View / Appearance / Auto Zoom on load / ON which excludes drawings saved with Layout Viewports?

1933QCAD (main)Bug ReportLowAdvanced SVG export file overwrite check doesn't use up...Assigned
Task Description

In the Advance SVG Export dialog, when I edit the filename to be different than the default file that already exists and then clear the checkbox for “Overwrite existing file without asking” just to make sure that I haven’t already created a file with the modified name as well, then I get a popup warning that the export would overwrite the default filename, not the name as edited. In other words, the overwrite check ignored the fact that I edited the filename.

Observed on MacOS Mojave (10.14), but probably applies to all.

1934QCAD (main)Feature RequestLowDiametric text - overlaidAssigned
Task Description

Diametric text is always placed above a horizontal measurement.

I often want to indicate both the inside and outside diameter of an object e.g. a wheel using diametric text. The text is overlaid and illegible.

To avoid text overlapping, I use Horizontal Aligned because I can control the position of the text to avoid illegible text.

A better method would be to alternate the placement of diametric text (alternatively) above and below a measurement so that in the majority of cases an overlap would be avoided.

Similarly for a vertical measurement, the text is overlaid and illegible.

When the angle is almost vertical, the angle controls the side the text appears however it also reverses the direction of the text (which is logical but not attractive).

Kind regards

1936QCAD (main)Bug ReportLowver 3.23 not saving font informationAssigned
Task Description

The attached file is not saving font preference.
All fonts on the online layer are reported as the standard font. If I highlight one or all of the text entities and change the font to something like Yu gothic light, the property page reports yu gothic light and the screen reflects the changed font.
If I save, close and reload, the fonts for all text is again “standard”.

So then I try to enter new text via the “A” draw text command icon. I select “Broadway.ttf” as the main font in the text entry dialog.
One word “Broadway” is entered as the text. it appears on the upper left of the screen as expected and the font name is Broadway in the property editor. If I look at the dxf file source there is a whole bunch of text styles.
I save and close the file, and then open it again. Now the word Broadway has changed to font name “standard” in the property editor and is very definitely not the Broadway.ttf font.

I am not the originator of the file, I am just trying to change the font. If I start a new file and enter new text the font saves just fine, so I am thinking it is a setting somewhere, but I am unable to find it.

We (me and my customers) use these files for engraving so exact font is critical.

1843QCAD/CAMBug ReportLowCreating ToolPath StallsAssigned
Task Description

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.

Task Description

Hi Andrew

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

Task Description

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

1877QCAD/CAMFeature RequestLowPost Processor TutorialAssigned
Task Description

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?

Task Description

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”.

1911QCAD/CAMFeature RequestLowDrill ToolpathAssigned
Task Description

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 find it hard to select the correct tool by a small bug

1913QCAD/CAMBug ReportLow3D Simulation Behaves oddAssigned
Task Description

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.
