 780 QCAD (main)Feature RequestLow Hatch should always follow changes to its contour Closed
2 Task Description

I drew a closed polyline, hatched it (on the same layer) and then moved a node... the hatch didn’t change as one would expect.

It would be great if hatches would follow any changes to its contour.

 881 QCAD (main)Feature RequestLow Line orthogonal to line and tangential to arc, circle o ...Closed
2 Task Description

It would be useful to have an additional line tool that could be drawn tangent to an existing circle and perpendicular to a line.

 1006 QCAD (main)Feature RequestLow Making zoom in / out speed configurable Closed
2 Task Description

Although this report is specific to Magic Mouse on OS-X Mountain Lion, since mice are a fairly common commodity across all platforms, I suspect this may be a more common issue across multiple platforms. The issue is that with my Magic Mouse, when I zoom into or out of the drawing by dragging my finger forward or backward on the mouse (equivalent of rolling the scroll wheel of a mechanical mouse), the zoom keeps zooming (in either direction) LONG after I have stopped moving my finger! Now, I do have my scroll speed set high because I have a large monitor and like to get around on it fast. But QCAD is the only application that does this exaggerated scrolling, so there must be some missing conversion or time constant issue going on here. I could change the speed of my mouse and that would likely fix it: in QCAD. But then all my other apps would be too slow with the mouse. Maybe there needs to be a custom setting in the Preferences that allows to user to set the mouse speed for just inside QCAD. But I suspect its more just a mouse speed parameter conversion error.

 1015 QCAD (main)Feature RequestLow To add Point Style options Closed
2 Task Description

I use points in my drawing s often for referencing and construction purposes, I would like to request that in the application settings some options could be added for point styles.
For example:
Style - cross with circle or other styles useful for temporary construction referencing.
The option to set the size either relative to the screen or indeed in absolute units.

2 Task Description


 1270 QCAD (main)Feature RequestLow Modify > Detect Duplicates: add option to treat reverse ...Closed
2 Task Description

Add option to treat entities with identical geometry but reversed direction as duplicates.

Original report:
In the attached example, there is a double line from 46/28 to 46/-28.
However it is not detected when searching for double objects.

 1644 QCAD (main)Bug ReportLow Crash on hide all layers button / mixed layers of diffe ...Closed
2 Task Description


it occorred to me now several times, that I have been working on 2 or more files simultaneously when suddenly on some operations layers from one file showed up in the other file. nothing was pasted when it happened just many files open, or few files with many layers in them. (about 100 layers, but sometimes also only 10 layers)
Today I disabled a single layer in one dxf (A) which caused all layers of the other dxf (B) to show up in the layer list (and the layers that should show up were all gone).

I knew this already from 2 more occurances and tried the best to undo all my changes in (A) before “emergency saving” (A). I closed one of the two dxf files (A), leaving one open (B). Everthing seemed pretty normal again. Then pressing the “hide all layers” button just crashed qcad without any message. That crash on “hide all layers” happened twice today). I can’t reproduce the crash right now, but will add details here when I find something. As far as I remember the bug occured already in qcad 3.17, but I’m now on 3.18.1

thanks :)

 1695 QCAD (main)Bug ReportLow Context menu: editing tools not working in paper space Closed
2 Task Description

Tools not working from context menu in paper space.

 1792 QCAD (main)Bug ReportLow Dimension > Angular: transformations broken Closed
2 Task Description

(I originally described the problem in the forum: https://qcad.org/rsforum/viewtopic.php?f=33&t=5721 )
(The problem was also reproduced by user “Husky” so it not installation specific.)

I have a model where one of the details is as shown in attachment 1

However, when I create a viewport and display the part in the the layout the angular measurement is another. See attachment 2.

In the model it should be noted that the part displayed is a detail copied with a different scale as to Zoom in on a detail in order to put dimensions on it. It was created by copying a part of the model and pasting it back in the model but with 3x zoom.

I have also included the full .dxf file in the hope that it helps you both reproduce and fix this issue

Note: The same problem seems to also produce “ghostlines” in other viewports in the layout which is not present in the model. Removing the angular measurement also removed the ghostline. You can observe the issue by looking at layout2 and you can see a line (dimension layer) going from top right corner of the viewport towards the lower left. This line is not present in the model and appears to be some strange extension to the angular dimension the detail that is just to the top right in the model.

I’m not able to import any dxf or dwg.

 388 QCAD (main)Feature RequestLow More options for Polygons ... Closed
3 Task Description

Possibility to draw Polygons with a given dimension for across flats (not only corners).

 408 QCAD (main)Feature RequestLow Script Macro recorder Closed
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.

 761 QCAD (main)Feature RequestLow Colour Indicators for Layer List Closed
3 Task Description

Layers are great for organizing a project. For construction lines alone I sometimes use 3 and more layers. And then there are more layers for each part I design. Each with its own colour.

And when a project gets bigger I start wishing for a quick overview in the layer list to the colours I use on them. So I wish for colour indicators on the layer list to quickly identify the membership of a line to a layer.

I have a small image attached to make you see, what I mean.

 889 QCAD (main)Feature RequestLow Filter the current selection to only include entities o ...Closed
3 Task Description

The property editor should do,
if I change
Selection: All(xx)
by Filtering by Entity Type
Selection: Circle(xx)
only the selected enteties(in this case the circles) should be selected, so we will be able to copy, delete ... directly

Der Eigenschaften Editor sollte wenn die
Auswahl: Alle(xxx) auf z.B.
Auswahl: Kreise (xx) geändert wird
auch nur diese Selektierung in der Zeichnung auswählen um direct kopieren, löschen ... zu können

 1031 QCAD (main)Feature RequestLow Remember last layer active, when restating existing dra ...Closed
3 Task Description

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

Please see topic:

 431 QCAD (main)Feature RequestLow Construction lines Closed
4 Task Description

Construction lines (’infinite’ lines).

 760 QCAD (main)Feature RequestLow Hierarchical Layers Closed
4 Task Description

Please, dear Feature Fairy, I wish for hierarchical layers. That would make organizing my projects a little bit easier.

Let me show you, what I mean: (see Attachment)

 1180 dxflibBug ReportLow dxflib cannot open files with international characters  ...Closed
4 Task Description

With dxflib, QCAD cannot open any file with Chinese file name or path name, it popups a “Important Error” dialog.
But the writing (”Save As” command) with Chinese file name or path name is of no problem.
Does it mean dxflib can only handle single byte characters file name/path name?
WinXP, QCAD 3.8.0

 1435 QCAD (main)Feature RequestLow Default Template for new Drawing Closed
4 Task Description

It would be great if the user could choose a default template for new drawings.

There exists already a “File → New from Template” feature, where I can choose a template, but in most cases I want my new drawings to be based on my default template.
It would be very convenient if there is an option to set the default template and use it for the “File → New” function.

 647 QCAD (main)Feature RequestLow Customize line type Closed
5 Task Description

I would like to get a submenu in properties to define own line types, i.e. one dash and three points or line + block.

Edit: Add support for custom line types defined in DXF / DWG files.

 335 QCAD (main)Feature RequestLow Drawing preferences: Change font of dimensions Closed

I can work with be “old” binary for now (seems to work with the new libraries even it was not compiled newly), so it’s not that urgent.
