1407QCAD (main)Feature RequestLowSplines: add support for knot weights, start-, end tang...Assigned
Task Description

Attached DWG/DXF files are incorrectly read by QCAD.
They contain splines drawn using ZWCAD and saved as DWG/DXF version 2000.
Above splines are polylines created with autolisp routine which converts spline to polyline, so you can see how splines should actually be drawn.

First spline is created with fit points: 2,2 4,4 6,2
Then copied and applied weight of 2 on central control point.
Then copied again and applied weight of 0.5 on central control point.

Second spline is created with fit points: 6,2 8,4 10,2 with vertical start and end tangent.
Then copied and applied fit tolerance of 1 for fit points.

Third spline is created with fit points: 10,2 12,4 14,2 with horizontal start and end tangent.

Fourth and fifth spline are correctly drawn by QCAD.

Task Description

Tools to add control points to existing splines and remove control points.

736QCAD (main)Bug ReportLowsnap tool menu is shown before specifiv tool menuAssigned
Task Description

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.

QCAD is running on Mac OS Mountain Lion.

1428QCAD (main)Feature RequestLowSnap middle of the minimum distance between two entity'...Assigned
5 Task Description


from time to time I need to place a circle etc precisely between two entity’s - what is a lot of construction work to get it correct. With the new “Info tool “Distance Entity to Entity” we have already the base for a new snap tool which could help to get rid of the time consuming construction process in cases like this. I would appreciate to get a new snap tool which is able to figure out the shortest distance between to entity’s and then will snap to the middle of it.

Pic 1: Given situation
Pic 2: Result after using this new snap tool

Would it make also cense to have a second new snap tool which works opposite for the furthermost distance between two entity’s?

817QCAD (main)Feature RequestLowSnap and cut all intersection in a given area tool ...Assigned
1 Task Description

As we all know - from time to time - it is a lot of work to prepare a part of a drawing for a hatch.
To get rid of one of the basic task (cutting lines along the desired hatch boundary) it would be nice to have an add-on - or what ever - what would cut ALL intersection in a drawing (or just on one layer, or just based on a selection etc.) with just a mouse click. Then it would be much faster and easier to do the selection for the hatch boundaries.
The user could decide to make it directly in his drawing or he like to duplicate the drawing to an extra layer where this function will be used ....

Clive mentioned on this:
Maybe a tool like this could be an additional ‘Snap’ selection option - select all snap intersections or select snap intersections within a boundary! then as you suggest ‘cut’ at the intersection points.

728QCAD (main)Performance IssueLowSlow loading of drawing with many block insertsAssigned

566QCAD (main)Feature RequestLowShortkey for rectangle text rotationAssigned
Task Description

I would like to get a shortkey like ‘+’ to rotate text at 90° clockwise.

564QCAD (main)Feature RequestLowSettings organisation in levelAssigned
Task Description

As an old professional “documentation writer and user inteface designer” but IMHO, I’m not convinced that the “Application preferences” are correctly organised for ease of understanding and using them.
These settings are organised in 2 levels. Some of the first levels have their own settings (e.g. “Graphics view”) while most others don’t (e.g. “Load/save”). May I humbly ;-) suggest some consistency rules :
- no sub-level if there is only one subject
- no items on main level if there are already 1 or more sub-level(s).
For instance :
- sub-level “Default Dimension settings” under “Dimension” is the only sub-level : then move these items under main level “Dimension” and suppress the sub-level ;
- the items under “Graphics view” main level (with several sub-levels)could be in a sub-level named “General” ;
Actually, “Graphics view” main level is the only one which has both its own items and sub-levels ;-))) ?

1549QCAD (main)Feature RequestLowSeparate Coordinate Display from Drawing DimensionsAssigned
Task Description


According to the changelog for version 3.9.3 the info tools and coordinate display are tied to the current drawing dimensions. For much of my use I prefer to have the dimensions format different. The main reason is that my customers want to see the format in fractions, but when I am drawing I’d rather see the decimal format to make sure what I am drawing is accurate. So I’d really be interested in seeing a separate full configuration of the display and info coordinates.

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?

523QCAD (main)Bug ReportLowSelection tool button in CAD tool bar shows line tools ...Assigned

The selection tool is not accessible:

Click on Selection Tool icon - left panel:

Left panel then shows line tool options.

Click “back” button at top of left panel:

426QCAD (main)Feature RequestLowScriptable entitiesAssigned
Task Description

Provide script functionality for entities:

  • Paint or decorate entity, for example based on custom properties assigned to the entity
  • Listen and react to events
408QCAD (main)Feature RequestLowScript Macro recorderAssigned
3 Task Description

Having practically no experience in scripting, a recorder that one could activate to memorize repetitive tasks (ie: inserting several layers with different attributes when starting a new drawing)would a useful tool to help get a start on scripting.

789QCAD (main)Feature RequestLowScale tool - mouse-pointer - inversely proportional sca...Assigned
Task Description

Bug Report or Feature Request ..... I’m not sure!

If I use the mouse-pointer in the Scale tool I’m not able to do an inversely proportional scale.
x - y locked or unlocked doesn’t matter in combine with the mouse pointer ...

1187QCAD (main)Feature RequestLowScale possibility for Info tools ...Assigned
2 Task Description

Now - after enjoying the great new “Scale” option for Dimensioning I like to ask for the same scale option for the “Info tools”.
It would be really nice to have more flexibility (without a pocket-calculator) in reading and displaying the Info tool results.

855QCAD (main)Feature RequestLowScale dimension on/off option ...Assigned
Task Description

QCAD 3.1.5 - has a new “Dimensioning Scale adjustment option” (Property editor/Linear Factor). NICE!!! :-)

What means - we are now able to change the dimension scale for existing dims!

My Feature request refers to new dimensions and I think it would be perfect to have a “Scale Factor - On/Off Option” for all Dim Tools.

That would bring us in the position to copy / scale a part of our drawing for a detail view and we could just use us usual the dimensioning tools (with a scale factor) for the dimensioning task ....

700QCAD (main)Bug ReportLowSaved 'hatched' block loses hatching when using isometr...Assigned
Task Description

Hatched block loses hatching when using isometric projection tool:
See -http://www.qcad.org/rsforum/viewtopic.php?f=32&p=7063#p7063

When manipulating a saved hatched block with the isometric tool it loses the hatching unless the block is exploded.

Is this normal behaviour here? or a bug?

783QCAD (main)Feature RequestLowSave as .dgn option missing in 3.0.8?Assigned
Task Description

Not really a bug I suppose but the save as.dgn file format is missing in snapshot 3.0.8 release.

Will this be available again soon?

38QCAD (main)Feature RequestVery LowSave / restore, export / import settingsAssigned
Task Description

Inside the application preference dialog:

  • save settings (asks for a name)
  • restore settings (picked from a list that contains all so far saved settings and some presets)
  • export settings (to a file)
  • import settings (from a file)

Export / import could be useful for companies to synchronize settings.

3 Task Description

An option to remember the last active layer in an exisisting drawing when reopening.

Please see topic:


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.

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 ...

1102QCAD (main)Feature RequestLowRay reference pointAssigned
1 Task Description

Using a horizontally/vertically ray means always I have to use a preset Reference point which is 0° for the horizontal Ray and 90° for the vertically Ray. The Reference point Option Box is deactivated.

It would be nice to be able to choose by myself between a Start and End Reference point like the vert./horiz. Line options.

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.

1369QCAD/CAMBug ReportVery Lowqcad-bin is trying to access non-existent /home/andrewAssigned
Task Description

I experience long start delays. I’ve trace the problem to the fact that I have autofs automounting my home directories. However, an strace of qcad-bin shows the following:

execve("/opt/ribbonsoft/qcad/qcad-3.12.6/qcad-bin", ["/opt/ribbonsoft/qcad/qcad-3.12.6"...], [/* 87 vars */]) = 0

stat("/home/andrew/local/qt/lib", 0x7fff4722f250) = -1 ENOENT (No such file or directory)

Since there is no “andrew” user here, I have to wait for automount to timeout which takes about 2m and is rather annoying.

1104QCAD (main)Feature RequestLowPrinting: Add support for page rangeAssigned
Task Description

When printing from the preview mode a standard Windows popup shows, letting me select the printer, number of copies and a page range. Unfortunately QCAD (or Windows) ignores the page range - it always prints all pages. So right now I always have to copy the parts I want to print, page them into a separate document and print that instead - even though I got all my stuff nicely lined up for printing on multiple pages.

1288QCAD (main)Feature RequestLowPrint Preview Scaled RulersAssigned
1 Task Description

Would be nice, if in print preview QCAD rulers would switch to paper dimensions. Chat here http://www.qcad.org/rsforum/viewtopic.php?f=89&t=3793

After all, print preview is not just the drawing on white, isn’t it? Everything else should stay in drawing units. Just the rulers, maybe a preference?

1172QCAD (main)Feature RequestLowPrint Preview - Add 'Place Paper Option' toolAssigned
Task Description

Often in print preview I need to move the paper around and position it with the ‘Move Paper Position’ tool, which is useful, but what would be an additional extra useful option would be a ‘Place Paper Here’ tool.

Then I could simply use this tool first and then use the ‘Move Paper Position’ tool afterwards to fine tune things!

If you look at the attached image you will see that in this students file they have got their drawing spread out all over the place:(

1577QCAD (main)Feature RequestLowPostfix for DIM / Remember last DIM Label ...Assigned
1 Task Description


unfortunately I need to use from time to time different Units in a drawing. It works nice with the Scale possibility but to keep my drawing readable I need to label then the DIM accordingly. Sadly I don’t have a Postfix option so I work with a workaround what means I use <>”, or <>’ and <>mm in the Prefix field. If I then terminate the DIM tool and start it again I will loose my settings except the Scale Factor.

May I ask for an additional Postfix option or/and a remember functionality of those fields?

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 .... ;-)

770QCAD (main)Feature RequestLowPolyline tool to delete segments between two nodes, lea...Assigned
1 Task Description

I guess this is a case of wording and wrong expectations.

The polyline tool “Delete Segments between two nodes” removes nodes, but not segments as the title and the icon suggests.

I propose to rename it to “Delete Nodes between two nodes”.

A tool which actually removes line segments from a polyline, leaving gaps, could indeed be useful to some users.

I think of a straight polyline with several segments. Then I remove some segments. I end up with a polyline with “holes” in it. Now I could stretch that polyline and all the remaining segments and holes stretch proportionally. Could be handy some times.
