Many times, after pressing the space bar to access the command line, accidentally an space character is added at the start of the line. It’s very difficult to see it.

1452QCAD (main)Feature RequestLowColour opacity optionAssigned

 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.

 1145 QCAD (main)Bug ReportHigh Closing inactive tab of a modified drawing: drawing fil ...Closed
Task Description

Steps to reproduce:

1. Create new drawing and fill it with some contents that’s easy to distinguish, for example text “DRAWING 1”.
2. Save it as dr1.dxf
3. Close it
4. Open dr1.dxf
5. Edit it, for example change text from “DRAWING 1” to “DRAWING 2” 6. Save changed file as dr2.dxf
7. Close it
8. Open dr1.dxf (it should have content “DRAWING 1”)
9. Open dr2.dxf (it should have content “DRAWING 2”)
10. Close tab dr1.dxf
10.1 Qcad will ask you to save changes.
10.2 Press “Yes” –> nothing happens, dialog doesn’t disappear.
10.3 Press “Discard” –> dialog disappears, tab gets closed
10.4 Tab that has content of file dr2.dxf (”DRAWING 2”) remains open but gets title “dr1.dxf” (!)
11. Close tab
12. Press “Yes” in dialog that asks to save changes

1. Open dr1.dxf
2. Open dr2.dxf
As you can see, both files have equal contents (”DRAWING 2”)

Expected results:

1. Files have their own contents.
2. Dialogs asking to save files disappear when checking “Yes”, “Cancel” or “Discard” 3. Tabs don’t change titles and associated file names when other tabs are closed.

 898 QCAD (main)Bug ReportLow Circle tool regression in git ec746571 Closed
Task Description

Git ec746571 introduced the following artifact:

  • Start circle tool, center and radius
  • Click on point to select radius
  • Circle appears, along with a line to the coordinate system origin; also circle is not closed at around where this ghost line hits the circle entity
  • Happens with any circle tool, in slightly different manners
  • Doesn’t happen with any other tool, as far as I can tell

100% reproducible, doesn’t happen on git 6171094d.

This ghost line is also added to existing circles; ie. opening a drawing that has circles, a ghost line is attached to each of them. Not always pointing to the origin, but seems kind of random (changes with zoom level etc.)

It doesn’t seem to be a part of the drawing as such, as in ZA will not zoom so that all these ghost lines are fully visible, but the visual artifact remains.

If relevant: Linux/amd64 (Ubuntu 12.04), Qt 4.8.1, GCC 4.6.3, and as said, QCAD git ec746571.

Lines on attached illustration were not actually drawn in any way, shape or form; also they behave as if a particular line and its corresponding circle were a block, except one end of the line is firmly attached to origin.

 930 QCAD (main)Bug ReportLow Chinese font type saving problem Closed
Task Description

Dear Sir:
I am an user in Taiwan. I need to use Chinese. While editing, the font appearance can be display in view port, but after saving-closing-re-opening, the font type is missing. For example, while I type Chinese with font type “B” or “C” and save the file, the font all become font type “A” with reopening and the “Main Font” selector inside “Text” dialog window is blank. I need to re-open “Text” dialogue window and re-select font type, then click the working view port, the display of text changes. Its inconvient. In previous version it’s ok. I can’t remember the exact version of well-saving-Chinese-font function because my computer is not in my house. It might be version 3.1.x. I don’t think it’s a major problem, but could you please deal with this problem while having time.

Task Description

I use a font that changes the characters of latin and greek to technical symbols.
http://www.fontspace.com/micronus/y145m-2009 The font is installed and working okee.
But in the text tool → special characters button → others I expect to see this modified character map but instead I see the standard unicode characters.
When I use a gtk tool gucharmap I can see the character map as expected.
Now it is really combersome to enter the special characters.

2140QCAD (main)SuggestionLowChanging navigation mode for mouse wheel doesn't change...Assigned
1 Task Description

Looks like error, but may be that’s feature request.

CAD software uses typical navigation behavior as:
Wheel = Zoom; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right.

Any other software like browsers, office software (openoffice writer, ms excel and so on), 2d paint software like GIMP (Photoshop and so on) uses other behavior:
Wheel = Scroll up/down; Ctrl+Wheel = Zoom; Shift+Wheel = Scroll left/right.

Users, that intensively use CAD and other software simultaneously prefer to make same behavior in their applications switching CAD scroll to plain mouse wheel.

QCAD’s “Application Preferences”: “Graphics View: Navigation”: “Mouse wheel/ two finger swipe”: “Scroll” allow user to assign scroll up/down to wheel mouse instead of Zoom. But there is mistake Ctrl+Wheel didn’t change to Zoom. Ctrl+Wheel continues to scroll up/down, as the wheel.
Wheel = Scroll up/down; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right. No zoom!

Draw manipulation at this mode like a hell: you need to use wheel in conjunction with Ctrl/Shift to point draw in desired position, than move your hand to +(-) for make desired zoom.

in QCAD3 RC2 points were printed as crosses, in QCAD3 RC4 they are printed as (very little) points. I think this isn’t a bug but a feature. ;-)

Task Description

Change a quote value modify the drawing + link quotes with entities

In other words, makes quotes editable AND linked to entities.

  • Today in the properties, the value is read only. Being able to edit the value would modify the linked entity properties to fit the new quote.
  • Changing a property would change the linked quotes accordingly. Today, if I change a circle diameter which is quoted, the quote remain where it was and is no more relevant.
