3 Task Description

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.

3dconnexion DOT com/buy/shop.html?3dxcp=GA_GA_search_google_US_Brand

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.

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.

1760QCAD (main)Bug ReportVery LowSelf-crossing polylines can't be cut twice at segment c...Assigned
Task Description

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 


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.

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:

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.

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

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.


2011QCAD Community EditionSuggestionVery LowUpdate QCAD CE SpatialIndex module to latest versionAssigned
Task Description

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.


Here is the current spec file for version

It looks like qcad is incompatible with versions above 1.8.5.

Are there plans to port to the new version?

Thanks in advance.

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.

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.

2050QCAD Community EditionBug ReportVery LowFlexPainter dosen't workAssigned
Task Description

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).

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.

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.

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.

293QCAD (main)Feature RequestLowmulti-select for blocksAssigned
Task Description

It would be nice if one could select multiple blocks in the block list at once (holding ctrl or ctrl+shift). Main purpose would be to delete them if they are not needed anymore. If possible, the same applies to layers.

316QCAD (main)Feature RequestLowBlocks list and selected blockAssigned

Wouldn’t it be nice, if selecting a block in model view would somehow highlight (just like clicking a block in the list does) the selected block in the “Block List” window?

(Feature request sounds a little harsh, enhancement proposal would seem more apt.)

355QCAD (main)Feature RequestLowRemember function for dimension OptionAssigned
Task Description

I think it would be nice to have more flexibility for Prefix etc. option (not only the drop down with a given choice) and a remember function for all those fields like postfix and tolerance.

Why Remember Function:
If I use a postfix like <>” in the postfix field I’m only able to use it for this particular dimension type at this time. If I change the type (from Horizontal to vertical or what ever) I have always to repeat my postfix. The same with tolerances.

There is an issue importing from Autocad:
lines and quotes (both arrows and text) appear too much big (see attachment).
I can fix quotes modifying dimensions in “current drawing preferences”, but lines are still too thick.

Furthermore, Autocad opens Qcad’s dxf files showing wrong quotes.

512QCAD (main)Feature RequestLowModify stretch and Restrict orthoAssigned
1 Task Description

The modify stretch tool wants first and second corner, start and end point, then starts afresh. When I turn on restrict horizontally eg to align two points between start and end, the restriction sticks and I have to call restrict none, to be able to perform the next iteration, set the first corner then.

So, in the quest for a comfortable user interface, it was nice, if the modify stretch first/second corners parameter setting was not affected by current restrict/ortho etc. settings. Actually, that does not make any sense at all anyways, does it, a rectangle is defined by two degrees of freedom, isnt it?
