Task Description

If there is no selection the Properties Editor could be used to predefine the properties of to be drawn elements.

724QCAD (main)Feature RequestLowUseless reference point entering when moving relativelyAssigned
Task Description

this is a usability feature request:

If you want to move an object relatively to any point (e.g. by entering @x;y in commandline) it does’nt make sense to enter a starting reference point. Of course this is possible by clicking to any location on the screen. But it’s difficult to change between mouse and keyboard so often.

It should be possible to enter a “don’t care” or “any” reference point by pressing a keyboard shortcut (e.g. enter like in AutoCAD).

721QCAD (main)Bug ReportLowVertical dimensions imported as horizontal dimensionsAssigned
Task Description

Vertical dimensions created with 3rd party applications are sometimes imported as horizontal dimensions with length 0. Changing the angle in the property editor fixes the problem.
Problem occurs in QCAD 2.2 and QCAD 3.0.

705QCAD (main)Bug ReportLowVerwaltung Library Resourcen und Favoriten ....Assigned
Task Description

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.

1915QCAD (main)SuggestionLowViewport does not rotate view-port when changed in pape...Assigned
Task Description

To reproduce

1. Select a new view-port in model-space
2. Select the appropriate paper-space
3. When the paper space opens change the angle of the viewport.


The object in the viewport changes but the viewport itself remains unchanged


That both the view-port and the object changes angle as the angle is updated


If you abort the placement (but keep the angle) and go back to model-space and then redo the operation the view-port is rotated along the angle. It seems that the viewport only picks up the initial angle once the paper-space is open and ignores any changes thereafter


1. Select the view-port per normal in model-space
2. Open the paper-space and set the wanted angle but do not place the view-port in paper space
3. Abort the placement on paper-space and redo the whole operation

Once the paper space is opened again the view-port will have the chosen angle

1999QCAD (main)Feature RequestLowViewport: Add additional properties for controlling dim...Assigned
1 Task Description

When working with multiple Viewports with different scale it could be very useful to have extra properties controlling how dimensions are rendered in the viewport:

E.g an extra “Dimension Scale” under “Scale” in the Viewport selection’s ‘Specific Properties’ section, could allow having the same size when printed.
This Dimension Scale would be multiplied on top of the Scale value, but only for Dimensions rendering.

Toggle button for hiding any dimensions in the Viewport. Maybe this should be controlled by being able to specify a Layer that should be hidden in this Viewport only, then I could select my Dimensions layer here.

The Viewport properties:

637QCAD (main)Feature RequestLowViewports / View ListAssigned
Task Description

1. The Scrollbars for each window in the Viewports has the same size like the normal used scrollbars for windows. If you are working on a normal size Monitor it “steals” a lot of “working space”. Is there any possibility to make the scrollbars smaller or just a line to separate the windows so that I have to navigate with Keyboard and mouse?

2. I thing the Viewports and the View List belongs together - is it possible to get a button in the “View List / Tool Bar” to choose a Viewport style instead of “walking” the long way over the “Drawing preferences” Menu?

Task Description

When selecting multiple blocks that contain the same attribute names, attribute properties appear with the values of the last selected block instead of “various”. I do not know if this is a “bug” or developer option, but “various” would be better in my opinion.

1 Task Description

I find myself with reasonable regularity needing to change the background color between black and white. It would be much more efficient to have a toggle button on the ribbon to make this sort of instant (kind of like the “screen based line types” button works but make it for background color and just between black and white or let people define their dark and light themes and toggle the background between the two.

Task Description

It would be nice if QCAD spit some kind of warning message when trying to render a layer with a name that doesn’t exist (and perhaps render nothing), rather than silently rendering an empty image. :D

The 3dConnexion Space Navigator would be wonderful as a pan and zoom control. I find it extremely useful in SketchUp and when I switch from that to QCAD am always disappointed to find it doesn’t work.

While full support for the buttons and such would be nice, just the ability to map the axis to pan and zoom would be wonderful.

2021QCAD (main)Performance IssueVery LowCannot work with big dwg filesAssigned
Task Description

Openning a big file or doing any action in it, takes minutes to load.
Even dragging the scrollbar slightly left or right, takes mintues to redraw the canvas again, which makes QCAD un-usable for professional use.
Is there a way to make QCAD usable, after loading completed:
- Like suppressing edit until user says so,
- or taking snapshots of rendered canvases to another file and use it, as windows uses thumb.db ( for negative latency :P )

PS: I wish I could help a bit, but my hand are tied. I am just a java freak, I am opt to any idea of porting it to java, if she is still alive.

1765QCAD (main)Bug ReportVery LowErrors with polyline offsetAssigned
1 Task Description

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.

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.


1974QCAD (main)Bug ReportVery LowFile > Print Preview: Cannot move paper in new drawingUnconfirmed
Task Description

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:

Version: (3.21.1)
Build Date:
Jul 2 2018

Qt Version:
gcc 6.3.1

Thanks for a great product.

2050QCAD Community EditionBug ReportVery LowFlexPainter dosen't workAssigned

FlexPainter works in the Pro version of QCad but not in the Comunity one.
If it’s not supposed to works in the latter, maybe, it would be better to remove it from the menu (Misc > Script Examples > Mathematics).

1691QCAD (main)Bug ReportVery LowIssue with Layouts after "File-Revert"Assigned

2048QCAD (main)Bug ReportVery LowMove / Copy to current layer fails when reference point...Assigned
Task Description

QCAD 3.24.2 / macOS x86_64 10.14.6

Starting with empty doc:
1. Draw any object (e.g. a rectangle) on layer 0.
2. Create new layer (”1”) with color, say yellow.
3. Select new layer
4. Select new object
5. Modify → Move / Copy
6. Click reference point
7. Click target point same as reference point
8. In “Move / Copy Options” dialog, select “Delete Original” and check “Use current layer and attributes.” Click OK.

The moved object stays on the layer it was previously on. Using “Move / Copy” as a quick way to move a selection between layers is not useful even though it appears to be the recommended way in a Google search.

Note: if “Keep Original” is selected instead, the copied object is placed on the current layer and the original object remains on its layer, as expected.

Note: if the target point is different from the reference point, the moved object is placed on the current layer as expected.

There are other workarounds too, cut / paste with “To current layer” checked seems to work, as does chaging the layer in the Properties Editor.

1788QCAD (main)Feature RequestVery LowNew snap: reference points of a block referencesAssigned
Task Description

I know this was reported and fixed before ...


... but it looks like we have the issue now back with some kind of variation.

If I use the test drawing which I posted in 2013 ( FS#843 ) it works still as expected after it was fixed.

If I create a new block it won’t work in a new drawing nor in the old test drawing - no chance to snap to the Block Reference.

Edit: New Test drawing:

2068QCAD Community EditionBug ReportVery LowNon-english text in upper/lower index becomes UTF codeAssigned

1900QCAD (main)Bug ReportVery LowRemote shares initially not accessible.Assigned
Task Description

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.
