859QCAD (main)Feature RequestLowPersistent selection button added to tool set.Assigned
Task Description

It would be useful to have a persistent selection button added to the ‘selection’ tool set.

This would allow the user to set persistent selection as and when needed for the current drawing one is working on, rather than going the long route through the ‘Application’ preferences dialog.

860QCAD (main)Feature RequestLow"Create Library item from selection" default Path ...Assigned
1 Task Description

Default Path for “Create Library item from selection” / “Save us” is C:\Programme\QCAD pro 3.1.6 ...
... regardless of the settings in the “Application Preferences / Library Browser / for Library Sources.
And QCAD doesn’t remember the last path choice ....

If I have to save 50 Library Items I have to navigate 50 times thru my system to find - the same place.

It would be nice if QCAD would point in first place to the Library Source or, at least, remember the last used path ... ;-)

Task Description

“Create New Drawing from Template” Browser can’t readout the Page orientation ...

866QCAD (main)Feature RequestLowPaste block reference: add third option to rename paste...Assigned
Task Description


Drawing 1: Blockname X is part of a selection, I copy this selection into the clipboard to use it in an other drawing.

Switch to Drawing 2, this drawing has also a Blockname X but with a different content.

Use the clipboard paste function - the clipboard content will be modified (only the Block) by the drawing 2 block content.

No warning pops up - it just happens!

868QCAD (main)Feature RequestLowOption to save to dwt - drawing template.Assigned
Task Description

An option to save to dwt (drawing template) would be so very useful.
Please see related topic:


873QCAD (main)Feature RequestLowcommand line does not accept distance value for funtion...Assigned
Task Description

In the comnmand line, I can sucessfully enter for example the radius of a circle to draw (Space 100 Enter) but the command line does not accept a value for the distance when drawing parallel lines (l p space 100 enter → error).

879QCAD (main)Bug ReportLowAutosave function not working if file is opened directl...Assigned
Task Description

If a file is opened by clicking on it in an open ZIP archive, autosave will not work.

Linux Mint -64

Autosave function not working, error warning given instead!

883QCAD (main)Feature RequestLowInformation tool for finding the centroid of an irregul...Assigned
Task Description

It would be extreamly useful to have an additional info tool to be able to find the centre of gravity (centroid) for an irregualr polygon.
For info please see:http://en.wikipedia.org/wiki/Centroid

Actually a tool whicn gives an option for finding the centre and centroid of polygons would be good.

893QCAD (main)Bug ReportLowLibrary Browser - Edit Library Item - opens drawings al...Assigned
Task Description

Library Browser - Edit Library Item - opens drawings always with grid.

- If I switch between opened drawings back and forth the grid will disappear ....
- If I switch the grid button between visible (it is already visible!) and invisible the grid is gone ....

Just Cosmetic ... ;-)

894QCAD (main)Feature RequestLowModify - Clip to Rectangle: copy area to clipboardAssigned
1 Task Description

New mode for clip to rectangle: copy contents of rectangular area to clipboard.

895QCAD (main)Feature RequestLowArea calculation based on existing entitiesAssigned
4 Task Description

Use case:

  • Start tool
  • Choose one entity of the contour
  • If contour is closed, area of closed contour is calculated an printed in the command line history
  • Configuration parameters: segment length for arc interpolation
901QCAD (main)Feature RequestLowDimension text stylesAssigned
Task Description

Support custom dimension text styles for imported DXF / DWG files.

908QCAD (main)Feature RequestLowLibrary Browser Block Delete FunctionAssigned
1 Task Description

It would be very helpful if the library browser had a delete function.

I know that this can be very risky for some people, but it is the easiest
way to see clearly what you delete.


922QCAD (main)Feature RequestLowPossibility to control the order in the Property editor...Assigned
Task Description

It would be nice and helpful if we had the possibility to control the order of Attributes - shown in the property editor.
I found a solution for myself with using numbers in the Attribute definition tag - but that isn’t really a nice solution.
If I could hide my numbering ... everything would be fine for me .... ;-)

923QCAD (main)Feature RequestLowDiagramming (Intelligent Orthogonal Connectors)Assigned
1 Task Description


With the new block attribute feature available in QCAD 3.3, there’s little to be done in order to make QCAD a good environment for typesetting circuits and other diagrams. In particular, the only killer feature that lasts is support for connectors: orthogonal lines that connecting one endpoint to another creates a connection line; when the concerned entities are moved the connection line is re-arranged. I’d like to know whether commercial support for this feature is available.

927QCAD (main)Feature RequestLowFurther options for the 'Add Measurement' toolsAssigned
1 Task Description

Absolutely love the new options for adding the measurements in the current drawing.

I would like to see an additional option for only adding the text and not the lines also, maybe a simple check box would suffice here.

Of course at the moment I am able to use the property editor to select only the lines and move to a new layer and hide!

928QCAD (main)TaskLowCXF font editingAssigned
1 Task Description

Port CXF font editor to QCAD 3.
- Load CXF fonts (load glyphs into blocks)
- Save back to CXF format

936QCAD (main)Feature RequestLowDisproportional scaling of block referencesAssigned
Task Description


... doesn’t works proper at circles and ellipses.

Circles: the scale works only proportional even though I have the options for x and y.
Ellipses: The same but if I play around with the x, y fields it will freeze the scale possibility.

See discussion at:

951QCAD (main)Feature RequestLowExtra Option for Block attributes ...Assigned
Task Description

It would be nice to have the possibility to control the automatic Text orientation in Block attributes.
Something what would work like the DIM restriction: I can read the text horizontal and/or from the right side of the drawing sheet.

Right now I have the feeling that the Text orientation is dependent on the tool what I even use.
Different tools = different outcomes.

952QCAD (main)Feature RequestLowDimensions: manually control arrow positionAssigned
3 Task Description

See drawing: I can’t seem to be able to manually change to the “To” variants – that is, override the decision of the label/arrow placement engine.

The circle in the attachment is a borderline example of when even just in this form I would more like it on the outside. If the drawing is crowded in that area, it would be even more useful to have it the other way around.

962QCAD (main)Feature RequestLowDefault save / open directoriesAssigned
1 Task Description

Add the option to use a fixed path for the save to, open and CAM export directories.

(G code files are usually saved in on directory that the Control Program opens them up from so this would save a ton of mouse clicking)

964QCAD (main)Feature RequestLowNew tool request - 'Break Out Arc' from CircleAssigned
Task Description

It would be useful to be able to pick a Start and End point of an Arc within a Circle to then break this out. So in principle another break out tool.

Please see topic:http://www.qcad.org/rsforum/viewtopic.php?f=33&p=8826#p8826

Task Description

The Omega button to insert special characters is only available in rich text mode.
Make it available in simple text mode as well.

Task Description

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

986QCAD (main)Feature RequestLowDetect duplicates - only on selected areaAssigned
1 Task Description

It would be useful to have an additional option to only detect duplicates on user defined selection of drawing.
Please see topic:

990QCAD (main)Feature RequestLowDefault Names for Custom Property ...Assigned
Task Description

Property Editor - Geometry - Custom - Add Custom Property

It would be nice to have in “Application preferences” the possibility to predefine a couple Custom Property Names.
Right now I use the Custom Property function to add a DIN and the Material info to every Block. This project has a lot of DIN parts and I have to type again and again the names DIN ... Material ... DIN ... Material ... DIN ... Material ... DIN ... Material ... DIN ... Material ... you got my point ;-)

If I have predefined Names - I have just to fill out the value :-)

991QCAD (main)Feature RequestVery LowAdd warning when overwriting custom propertyAssigned
Task Description

Property Editor - Geometry - Custom - Add Custom Property

If I use an identical Name accidentally again in the Custom Property dialog - it will overwrite the first value with the same name without any warnings.

992QCAD (main)Feature RequestLowselections to stay selected when projecting to an isome...Assigned
Task Description

My request is that all selected entities stay selected after isometric projection, this would be useful for example if you need to modify the projection further after placing!
Maybe an extra button could be added in the ISO options?

995QCAD (main)Feature RequestLowProperty editor: add 'edit block' buttonAssigned
Task Description

Add a button to edit the block beside the block combo box that is shown when showing the properties of a block reference.

1005QCAD (main)Feature RequestLowMaking use of mouse buttons configurableAssigned
Task Description

According to the help, one requires a middle mouse to pan. Since few standard mice have middle buttons, this is a poor choice for this all important function. The default should be the right mouse button when ever the mouse is placed in an open area with nothing else to select. That way right click can still be used to invoke a pop down menu when ever the mouse is placed over an object that might have a need for pop down menu options. Additionally, the Pan mouse key should be alterable and selectable from a Preferences option, since if one does have a three button mouse, we should not prevent a user from employing this hardware if they have it. The same might be said for all mouse buttons to allow the user to configure the mouse operation to that which is most comfortable and efficient for their tasks.

1008QCAD (main)Bug ReportLowDXF (dxflib) compat issuesAssigned
Task Description

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

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.


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 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.)

1009QCAD (main)Feature RequestLowLayer Order is Alphabetical vs the Order Defined Origin...Assigned
Task Description

It would appear that when QCAD imports a DXF, it reorders the layers into alphabetical order (at least when importing R2011). I have not tested this extensively but on other programs, the order is different from alphabetical. Ideally the operator should be given a choice to order the layers as exported (assuming the DXF format remembers that) or alphabetical. This is because a drawing may have a certain stack up of layers (like a printed circuit board) and then alphabetic ordering is not useful nor desired.

1023QCAD (main)Feature RequestLowArrange points on a plan according to variation of dist...Assigned
1 Task Description

Arrange points on a plan according to an arithmetical, geometrical, logarithmic, customizable variation of distances

1026QCAD (main)Feature RequestLowSelection Filter also present in the Menu "Selection"Assigned
Task Description

It would be nice to have the Selection Filter also present in the Menu / Selection List

1027QCAD (main)Feature RequestLowRectangle with a 3 point determination ...Assigned
2 Task Description

Many times I’m faced with the situation that I have to use a rectangle related to other entities. Dimensions/Angle = unknown.

We have in QCAD a rectangle tool with a two point diagonal determination but this is limited to two points and it will only work in a horizontal and vertical direction.

My feature request is based on the idea to draw a rectangle with 3 points - regardless the angle.

1. First point: start

2. second point: determination of the first side (width?) and it will also provide the angle for the rectangle

3. third point: determination second side (height?)

I’m asking for an additional new tool? No - just as an option to the existing rectangle tool ...

1034QCAD (main)Feature RequestLowSupplementary note added to Application preferences dia...Assigned
Task Description

I think it would be useful to add a note to the Application preferences dialog window, to explain to the user the difference between ‘Application and Drawing’ preferences and how it effects drawings in QCAD.

Please see topic for more details and feedback:


1036QCAD (main)Feature RequestLowLayer list - drop down menu optionAssigned
Task Description

In the same way as the Pen tool has a drop down menu, would it be possible to have an option to configure the layer list in the same way. I am trying to create a bit more drawing space and it would be good if I could dock the layer list in the top of my window and only take up a single row space!

1042QCAD (main)Bug ReportVery LowPreferences dialogs: help button shown in dialog headerAssigned
Task Description


1044QCAD (main)Feature RequestLowRadian measure symbol for Geometry labeling ...Assigned
1 Task Description

We do not have a Radian measure tool but we can change the labeling of a Angular Dimensioning ...

It would be nice to have a “Radian measure symbol” in the Property Editor / Geometry / Label / Insert Symbol List.

1046QCAD (main)Feature RequestLowPlease add script bindings for Qt 4.8.6 and 5.2.1Assigned
Task Description

These are the versions Ubuntu 14.04 comes with, and since it’s an LTS version, it will linger around a while.

(Despite the fact that the Qt4 packages are versioned 4.8.5, qmake –version says 4.8.6, so it doesn’t find the 4.8.5 bindings.)


1051QCAD (main)Feature RequestLowInfo tool, polygonal area, possibility for a postfix la...Assigned
1 Task Description

... would be nice.

If I use the Info tool “Polygonal area” with the option “Add measurement to the drawing” I always have to edit the Value to make clear that we now looking to an area value like m² or ft².

I was thinking that a pre labeling (prefix/postfix) like the normal Dim tools could save me a couple extra steps ... ;-)

1056QCAD (main)RefactoringVery LowDead and wrong code in RSPlatform.cppAssigned

(truncated list to manage size)

I see that most of this was put in there as a kind of a note-to-self originally, however _SC_NPROCESSORS_ONLN is implemented by every realistically possible targets anyway, so for all practical purposes, this is dead weight.

A couple of questions remain, though:

  • #ifdef Q_OS_WIN32 should probably be Q_OS_WIN, so as to include win64 as well.
  • Assuming the real purpose for this function is to determine how many parts a particular task is to be split into in the future, if and when QCAD gets the need to split expensive tasks among multiple CPUS, “core” probably shouldn’t be static - CPUs are hot-pluggable today, and while one probably doesn’t do that on a laptop, it’s not unfeasible in, say, a VDI environment.


1067QCAD (main)Feature RequestLowFilling an area with a bitmapAssigned
Task Description

Being able to fill an area with a bitmap would be a nice addition to the already impressive feature list of QCAD.

1068QCAD (main)Feature RequestVery LowIsometric bitmapAssigned
Task Description

It would be a nice feature to be able to create an isometric projection of a bitmap.

1071QCAD (main)Feature RequestVery Low(Bitmap) scaling convenience optionAssigned
1 Task Description

This can be done as is in QCAD today, but a quick convenience UI bit would be much appreciated.

Suppose you are working off a bitmap image (transcribing old scan, or you got your apartment’s floor plan like this, because, uh, what tenant needs DXF). It has dimensions markers and everything, but fat chance it’ll be to actual CAD scale after importing.

So, to bring it to scale, you measure between two tick marks on the scale, compute ratio based on measurement and what’s written on the dimension line, and do a scale operation (you can also have QCAD compute the ratio by using math expression, whatever).

That works fine.

A purely just for convenience function to do that would be much appreciated: pick two points, enter what the actual distance between them is, poof bam, appropriate scaling operation is applied.

As a twist, there could be some other bitmap skewing options, like “the points I’ve selected are on a horizontal/vertical line/at an angle of X degrees, then the bitmap would also be applied this transform.

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.
