QCAD Bugtracker

When I create a simple drawing, I cannot export the gcode until I restart qcad.

general steps to reproduce the issue:
1. open a new drawing
2. Add a letter “D” near the origin in Arial font, about 7mm tall.
3. explode it
4. save the drawing
5. Fill in in the “cam configuration” 6. Select the drawing and generate the tool paths.
7. Hit the “export button” or the menu item.
8. Observe that you see the “camexport” command appears in the command section, but there is no file generated for the gcode.

If you restart qcad, then the gcode will export as expected. Also, it appears to work for more complicated drawings. I had the same issue, when I tried to generate the same thing, but using the string “November 2019” at 5mm height. I am using up to date MX Linux with kernel version 4.19.0. I also observed this behavior under Windows 10 professional.

Yesterday I set up a Windows 64 bit install of QCAD Pro which shows the same bug I have been seeing for a while in the Community linux git repo.

Create a new drawing and then go to “Print preview”. Enable “Move paper postion”, the cursor changes to the hand icon, but the paper position is unable to be moved. Only by saving the drawing, exiting the program, restarting and reopening the drawing, will the “Move paper postion” function correctly.

Affected versions tested:

Windows 64bit installer download, as of yesterday.
Linux 64bit build from git, about 20minutes ago.

For what it’s worth, this bug is not present in this previous git checkout:

Hallo Andrew,

Found a bug in the 3D Simulator execution

Hello, I found a bug.

Original file: 006–【武汉会展中心店】一层合用前室.dwg

Converted file: 006–【武汉会展中心店】一层合用前室.pdf

Command line: .\dwg2pdf.bat -f -a -recompute-dim -ltscale=1 -block=布局1 path

Bug description file: problem8.png

As you see. I use dwg2pdf to export the block named “布局1”. There are too many drawings missing.

Good afternoon, I found a bug.

Source file: B5.dwg.

Command line: .\dwg2pdf.bat -f -a -recompute-dim -ltscale=1 -font-substitution Standard GBK path

After I used the command, the message “Warning: standard font not found” occured. And B5.pdf is not found.
Convert is fail.

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.

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.

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.

Win7pro 32bit Qcad 3.23.0

Andrew,
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.

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.

Hallo Andrew,

Testing the drill toolpath I find it hard to select the correct tool by a small bug

My data files are stored on network shares (synology) with a GB link. QCAD Pro is run in Admin mode.

While in my Windows browser all remote shares are accessible (Green), in the QCAD file open menu they are initially shown as not accessible (Red). By accessing a specific drawing file in a remote share, the share will open and turn green.

Same behavior using ‘Open recent’. Always the message is given that the requested file does not exist, and the file is wiped from the ‘Recent Open’ list. Only if the share is first accessed through ‘Open’ with a random file, it will turn and a ‘recent open’ file for that share will open.

Drag and Drop from a remote share will never work.

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

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.

Win 7 32 bit QCAD 3.20.1

Ofsset of a base-line with arcs results in massive ammount of errors.
Most of them occur as a cluster of very tiny segments and are part of the offset. (zoom far in at the red circles)
Mostly they occur where the offsetted arcs should merely be trimmend pairwise.
Some occur as detached entities or as detached strings of entities very near the offset (strings not documented).
Spooks occur at opposite site when base-line is not closed.
360° curls can occur with R = Offset.
Null-entities may occur (not documented, hard to find and not able to copy).

The base-line is checked and sound and has mixed tangentially or not tangentially connected arcs.
Offsetting the mother base-line of the base in the file has similar effect but not all and/or different ones.
Also encountered with offseting polys from fonts.
Used to define pocket paths for CNC.
Detected because the CNC driver will not accept Self-crossers, Null-entities or open ends depending on the settings.

Work arround is to explode and select small entities but this does not solves the issues.
1) Choosing the tolerance large enough will detect small segments that should stay.
2) Recombining will generate new ones at the place where the main segments remain crossed.
Cleaning up the paths is a daunting process with some thousand segments for several offsets.

I assume this has an infuence on the CAM part of QCAD too unless the offset method is different.

Re-entering dividing problem from  FS#1757 

Divide the poly selecting near segment 1 at the segment crossing.
> A new node is inserted on the crossing and made start and end node.
Divide the poly again selecting near segment 2 at the segment crossing.
> no division appears to be done.

One can’t divide the second segment at the crossing

Presumed intended behaviour like  FS#1750

Drawing converted from inch to mm - undo leads to wrong dim label position. I can fix that with “Reset Label position” but it would be nice if QCAD could to that in first place.

QCad 3.19.2 Professional, 64bit, Liux Mint

Case:
1. Open some saved drawing with viewport entities on layout block (paper space). Print Preview mode is “On” automatically.
2. After “File-Revert” drawing is reopened on layout block (paper space), but now Print Previw mode is “Off” .

For example can try on “flange.dxf”

Hi,

I am using mac version and I have annoying issue with trackpad.
I use qcad primary with my trackpad and under application preferences (Graphics View/Navigation), my setting is as follows.
Mouse wheel / two finger swipe: Scroll (Trackpad...
Enable pan gesture : unticked (found that enabling this often goes into pan mode when I am just moving my pointer around)
Limit zoom and scroll to prevent overflows : ticked (hoping that this would prevent weird zooming issue. I will describe what I am experiencing later this page)
Reverse mouse wheel direction for zoom :unticked
Mouse wheel zoom factor: 1.02

Things work as expected:

• panning with two finger swipe

• and the rest

Issue I am experiencing:

Often, when I am zooming in and out with two finger gestures, the view suddenly sets to some weird state and my drawing goes off the ruler.
The mouse point remains where it is.

Workaround:
Reset viewpoint with autozoom and navigate around.

Expected zoom behaviour:
I expect viewpoint to zoom in / out at where my mouse pointer is or at least the centre of current view point.

Status Bar menu remains unchecked even it is toggled on or off

Print “Command Line” and as “Add measurement to drawing” works as expected.

Hi,

Even with the Application Preference, Library Browser, NO Update on Start up,
the Libray Browser scans the directory, a proces that can’t be stopped or closed.

I wanted to make it so, that SVG units translate 1:1 into CAD units; I use the German localized QCAD and entered 25,4 into the box with the wrong result, i.e. the same as 25; Entering 25.4 got me what I wanted: The question box needs the point and ignores the comma. Would be nice if it could use the localized separator.

Case:

Select a block array,
put it with “Copy with reference” or “Cut with reference” into the clipboard,
choose a reference point which isn’t in the center of the array,
use the paste tool / with option “flip pasted entities”

If I flip only in horizontal or vertical direction the preview box will double in size and I can’t place the entities precisely regarding to the reference point.
If I try to flip in both directions at the same time - you can’t see this effect.

I am doing a bit of landscaping and using a (big) ortophoto as one of my layers in order to sanity-check on the ground measurements.

The layer contains a point and the image and nothing else.

The image is a 8MB file: “PNG image data, 4200 x 2980, 8-bit/color RGB, non-interlaced” and it is scaled to 210 coordinate units (meter) horizontally in the drawing.

With approx 50% probability the image disappears during Save, as see for instance in this diff of the DXF file:

The point in the same layer does not similarly disappear, the bug only seems to affect images.

I have seen this bug from version 3.7.5.0 to git as of yesterday (63e06c778926a803bdfbffdf27b8c24d41511072).

I have not been able to correlate the bug with anything.

Looking closer at the DXF file (attached), there seems to be some residuce of attempts to insert images in protected/invisible layers, so this may be some kind of refcounting issue.

(Any chance of getting FreeBSD into the “Operating System” field ?)

Ruler ticks are not corresponding to the grid points,
Ruler will completely disappear at a certain zoom level,

Settings:

Git head as well as 3.4.5 (trial), both with dxflib 3.3.4.0.

Start up QCAD, (with existing or new configuration, doesn’t seem to matter), “Save as” the completely empty drawing, choose “R15 (dxflib)” on Pro (only this one is available on community), save drawing.

Fire up AutoCAD 2000, try to load the empty drawing just saved.

Result:

DXF read error
Error in APPID Table
DXF read error on line 941.
Invalid or incomplete DXF input -- drawing discarded.

Problem not present when a completely empty drawing saved using Teigha in R15 format is opened (ie. it just results in an empty drawing in AutoCAD 2000). Problem is also not present when saving an existing drawing with Pro (trial) with Teigha and opening it in AutoCAD 2000. Problem does present when trying to open a dxflib-saved drawing in AutoCAD 2000.

Empty drawings created with both dxflib 3.3.4.0 in QCAD Pro 3.4.5 trial and Teigha whatever in QCAD Pro trial 3.4.5 are attached. (Community Git 135fd0 is identical to Pro - same dxflib version.)

Isometric Projection used on a selection which contains blocks will mix up the layer affiliations.
No blocks - no problems

If I paste something from the clipboard to a drawing the scales of dims are wrong in the preview.

It is difficult to place it right with a confusing preview of that what I have to place ...

When creating a new file, selecting the e. g. line tool at first opens the linemenu and the snap tool menu as expected. After clicking on the back button twice (going back to the main menu) and selecting the e. g. circle menu, the snap tool menu is shown instead of the circle menu. Instead the circle menu is shown after pressing the back button again.

This only happens when clicking on the back button, but with any tool menu seleected. Pressing escape to go back does not show this problem.

Isometric view tool bar doesn`t remain ' docked’ when re-opening QCAD.

Ob dies ein Feature Request oder ein Bugreport ist weiß ich nicht ....

Hier meine Gedanken ....

In den Application Preferences kann ich mehrere Library Sources vorgeben. Ich habe eine auf dem HD und eine auf einen USB angegeben.

Wenn ich nun QCad auf der HD ausführe habe ich beide Ressourcen zur Verfügung. Schön! Natürlich habe ich auch im Library Browser meine Favoriten von beiden Ressourcen angegeben.

Wenn ich nun aber den USB entferne zeigt mir der Library Browser immer noch beide Resorcen als Name an - schalte ich nun um auf die USB Resource bekomme ich keinerlei Hinweis das diese momentan nicht zur Verfügung steht. Es passiert einfach NIX Es wäre schön wenn ich hier eine “Nicht verfügbar” Meldung bekommen würde.

Wenn ich nun meine Trotteligkeit bemerke und den USB wieder einstecke habe ich logischerweise wieder meine Library zur Verfügung ..... nur die auf den USB Stick verweisenden Favoriten sind auf Nimmerwiedersehen verschwunden. Die auf dem HD bleiben erhalten!

OK - um es ganz rund zu machen ein anderes Szenarios in “Steno”:
QCad Start vom USB - > Library Favoriten anlegen auf USB Library - > QCad schließen - > USB entfernen → QCad auf HD starten - > Library Favoriten auf USB sind verschwunden - > QCad HD schließen - > USB einstecken und QCad von USB starten = Favoriten auf USB bleiben verloren!

Wäre es hier nicht möglich die Favoriten Information dem USB mit auf dem Weg zu geben? Wenn ich eine Favoriten Auswahl auf dem USB nicht kontrollieren kann macht diese Möglichkeit kaum Sinn.
