 1831 QCAD (main)Bug ReportLow Block > Copy Block: attributes of block references are  ...Closed
1 Task Description

1) Open the attached dxf file
2) Right click on “vne_vent_odvod_ec_3f” block in Block list and select Copy block
3) Choose name
4) Insert reference of this Copy block to the modelspace
5) Save the file

1080QCAD (main)Feature RequestLowBitmap export: calculate size based on bounding box inc...Assigned
Task Description

I have created a drawing, where the CENTERS of the most outer lines have a distance of 3.06mm in both X and Y.
The line weight of these outer lines is 0.6mm, so the whole image is 3.06mm + 2* 0.6mm/2 = 3.12mm wide and long (center to center plus half of the line weight on every side).
Additionally in the export there is a frame around the image, making it 3.12 + 2*frame.
The export function however calculates 3.06mm when setting the resolution to 1000Pix/cm, so it does not include the line weights and the outer frame.

Task Description

When exporting bitmap images the crop is just a bit too tight, and is resulting in lost parts of the drawing. In QCAD2 there was a very small padding of pixels around the exported object that prevented that problem.

 686 QCAD (main)Bug ReportLow Bibliothekbrowser zeigt keinen Inhalt Closed
Task Description

Ich verwende QCAD normalerweise unter Windows 7 als Benutzer ohne Privilegien. In diesem Modus zeigt der Bibliothekbrowser keinen Inhalt. Der Pfad zur Bibliothek ist in den Applikationseinstellungen korrekt eingerichtet. Wenn ich auf “Aktualisieren” klicke, läuft der Vorgang ab, aber danach ist immer noch kein Inhalt im Browser sichtbar. Starte ich QCAD als Administrator, habe ich keinerlei Probleme mit dem Bibliothekbrowser. Ich vermute, dass bei der Installation von QCAD die Privilegien nicht richtig gesetzt wurden. Eine Neuinstallation hat allerdings keine Abhilfe geschaffen.

 642 DocumentationBug ReportLow Better explanaton for Layer '0' Closed
Task Description

Layer ‘0’ has some special function. E.g. it can not be deleted, it will contain the data of undeleted layers.

I recommend adding some explanations: Explain the function of Layer ‘0’ as third paragraph in chapter 12 of the manual. Further it should be recommended to never use this layer for drawing.

By the way: I consider this to be better than no layer undelete. BUT: is there really not way for a true layer undelete...

Task Description

Es wäre Arbeitserleichternd wenn ich bei den Optionen für Bemaßungen (Prefix/Postfix) eigene Präferenzen speichern könnte so das diese in allen Zeichnungen von mir verfügbar wären.
Zudem wäre es wünschenswert dieses nicht nur bei den Prefix sondern auch bei den Postfix Angaben nutzen zu können was dann alle(?) Manipulationen erschlagen würde.

 2007 QCAD (main)Bug ReportLow bbox.bat cannot write log file Closed

It would be great to be able select a print style (Page size, printer), and apply it to a batch of .dxf files to do a batch print of a multi-drawing job with separate files. I used this feature a ton in ACAD in my previous job.

2063QCAD (main)Performance IssueLowBad performance while zooming inside layout block with ...Assigned
Task Description

Zooming in and out is lagging to the point of unusable. This is happening in a layout block with the cursor pointing inside geometry with hatches. When the cursor is pointing outside the geometry zooming works as expected.
The attached file has a very simplified testcase that shows this problem almost in the same way as a more complex drawing with multiple layers and hatches.

edit: I also attached the more complex drawing because it is a bit unclear to me where the lagging stops. Outside the viewport or outside the paper.

I just noticed the selection box has the same problem!

 1889 DocumentationBug ReportLow Autosave fails for QCAD original cxf font location Closed
Task Description

Now I try the third time to post this .... :-( .... deleted by “wrong token”???????
However ...

Regarding to the online tutorial:

Opening a CXF Font for Editing

To load an existing CXF font file in QCAD to view and edit its glyphs, simply use the menu File > Open and choose the format filter “CXF Font Files (*.cxf)”. Then choose the font file you want to open. The fonts that come with QCAD are stored in directory “fonts” of your QCAD installation.

quote end

Editing the cxf font in the original QCAD font folder will lead to a error message triggered by the Autosave function:

File access error: “C:/Program Files/qcad-3.22.1-pro-win64/fonts\~~Husky_test_font.dxf”. Access is denied.
[15:34:58] Autosave failed: C:\Program Files\qcad-3.22.1-pro-win64\fonts\~Husky_test_font.dxf

Note: Windows will not save anything in a system folder and the process is terminated by windows.

Solution: Move the cxf font for editing from the QCAD folder to a unprotected folder like Documents/drawings.
After editing is done move it back to the QCAD font folder.

 417 QCAD (main)Feature RequestLow Autosave Dateinamen Nummer ersetzten mit Datum. Closed
Task Description

Wenn ich das Autosave System richtig verstanden habe funktioniert es so:

Nach Ablauf der eingestellten Zeit wird eine Datei mit Nummer im angegebenen Zielordner abgelegt.
Diese Nummer ist weder fortlaufend noch sicher auf- oder absteigend - also keinerlei Hinweis im Dateinamen für den Anwender welches nun die letzte Sicherung ist.
Ziel scheint zu sein das man eine Sicherung pro Tag hat, richtig?

Allerdings ist die Anzahl der Sicherungen pro Tag abhängig von der Anzahl der neu gestarteten QCAD Sitzungen. Starte ich das Programm einmal für den ganzen Tag habe ich eine einzige Sicherung von jeder bearbeiteten Zeichnung. Sicherungen haben dann die selbe Nummer und werden deshalb jeweils überschrieben.

Starte ich das Programm 10 mal pro Tag habe ich 10 Sicherungen (vorausgesetzt ich bearbeite die selbe Zeichnung in jeder Sitzung) mit unterschiedlichen und nicht in Reihe laufenden Nummern. Sicherungen können somit nicht überschrieben werden und am ende des Tages könnten leicht zig wenn nicht hunderte Sicherungen gespeichert sein.

Würde nun diese Nummer im Dateinamen ersetzt mit dem aktuellen Datum habe ich eine Sicherung pro Tag unabhängig wie oft ich QCAD an diesem Tag gestartet habe. Zudem kann der Anwender gleich den Sicherungstag im Dateinamen erkennen und muss sich nicht durch die “geändert am” Info sekundengenau kämpfen.

Macht das Sinn?

Task Description

Hi Andrew,

Just a little thing I noticed recently.

My default is set to save as DWG and indeed it does, however the auto-save feedback tells me that the file is saved to DXF, although it actually does save to DWG - no big deal but is this correct feedback?

Many thanks

1 Task Description

1917QCAD (main)Feature RequestLowAutomatic labels with static information of the drawingAssigned
Task Description

I would like static information of the drawing (like scale, creation-date, modified-date, revision etc) to be available as automatic labels to be placed in the drawing (with selectable style, font etc)

This would greatly simplify the creatin of title sections in the drawing and making sure it is consistent with the actual drawing and not requiring manual “synchronization”.

 221 QCAD (main)Feature RequestLow autocad dwg compatibility Closed
Task Description

DWG files created with QCAD display really fine now in autocad. There are only two minor issues for ACAD users:

1) ACAD complains, that they were not created with a licensed application. One may not be able to work around that one...

2) ACAD complains, that the file does not specify a codepage. For this one, there should be a way around, shouldn’t it?

I am very happy with the compatibility in the new QCAD. Thank you very much for all the efforts that went into it!


1681QCAD (main)Feature RequestLowAuto-dimensioningAssigned
Task Description

You can apply the command to Lines, PolyLine segments, Arcs, Circles, and Rings:

For linear entities parallel to an axis of the coordinate system, aligned Dimensions (parallel Dimensions) are created. For linear entities not parallel to an axis of the coordinate system, either aligned Dimensions (measuring the absolute distance between two points) or horizontal or vertical Dimensions (measuring the horizontal or vertical distance between two points) depending on where you move the pointer are created.

For curved entities, you can create radial, diameter, linear, angular, and arc length Dimensions.

To dimension entities:

Click Dimension > Auto (or type AutoDimension).
In the graphics area, select an entity to dimension.
Click to place the dimension line.
To use another dimension type for Circles or Arcs, specify an option:
Diameter. Creates a diameter Dimension.
Radial. Creates a radial Dimension for an Arc or Circle.
Linear. Creates a linear Dimension of the diameter of a Circle or an aligned, horizontal, or vertical Dimension between the end points of an Arc.
Angular. Dimensions the angle between the end points of an Arc.
Arc length. Dimensions an Arc length.
Note: The chosen option is the default the next time you use the AutoDimension command.

When you move the pointer during a linear dimensioning, you can:
Lock. Determines the current dimension type (aligned, horizontal, or vertical) regardless where you move the pointer.
Unlock. Unlocks the type of linear dimension used.
Press Enter.

In short, when you use this tool you click on an entity and it will know what dimension you’re looking for. For Circles, you can specify in the command window R or D for Radius or Diameter.
This would be extremely useful on large drawings where a lot of dimensioning is to be done. One tool and start clicking on entities for dimensioning.

 657 QCAD (main)Feature RequestLow Auto Zoom applied too often Closed
Task Description

Auto Zoom should not be applied every time you go back and forth between editing a block and the main drawing.
