QCAD Bugtracker

Depolyment issue with qcaddwg plugin.

- Create four arc segments representing a full circle
- Create polyline from segments

Empty polyline is created (caused by simplification).

QCAD crashes when you perform the following operations:

1. Create Polyline with just one segment.  
2. Delete the node with DELETE NODE(S) command.  
3. Press ESC several times.
(-> QCAD crashes..)

(Re-)combining polys touching at node with ‘create from selected’ leads to application crash.

QCAD 3.20.1 Win7 32bit

In the file example 2.

‘Create From Segments’ ‘OG’ includes and admits selection of segments on locked layers.

A)
-When selecting a segment on a not locked layer it can include segments on locked layers that connect to the string. (Assumed wrong)
-A copy of the segments on the locked layer(s) are included in the polyline. (Assumed wrong)
These segments are not removed from the locked layer(s) because of their locked nature. (Intended behaviour)
eg. ‘OG’ & selecting the arc at point A in the example file. The arc is on a not locked layer.

B)
-When selecting a segment on a locked layer it will fully remove segments that connect to the string on not locked layers. (Assumed very wrong)
-Connecting segments on the locked layer(s) will not be converted to a polyline because of their locked nature. (Intended behaviour)
eg. ‘OG’ & selecting the line at point B in the example file. The cyan lines are on a locked Layer.

Both A & B can be undone.

The example is a part of the ‘Skewing project’.

In some cases, loose arc segments result in errors.
See:
http://www.qcad.org/rsforum/viewtopic.php?f=33&t=3573

Selecting the polyline is not possible.
Possibly related to update of DrawPolyline tool.

Exception due to invalid include path.

... just cosmetic!

Rectangle with size: The option box “Reference Point” is a bit to small to show the whole text of the chosen option.

English / German = same behavior.

Draw > Line > Parallel
- switch type to Line, XLine or Ray
- switch back to Auto
- Parallel is always line segment

When user activated LIne → Parallel (LP), there’s two input fields - Distance and Number. Keyboard shortcut Alt-N activated Number input field very well, but shortcut Alt-D activate menu Draw instead. So user forced to point Distance input field by mouse.

That’ because conflicting letter D.

Make a letter as shortcut (Distance) will remove problem b’coz no menu or option assigned to Alt-A combination

If I insert a bitmap the relative zero point (RZ) isn’t set at all. It will be set at the mouse position in the moment when I terminate the tool.

This leads among other things that I can’t use the Alt key for ortho mode or other tools for restrictions.

Draw > Image broken due to UI file resource not being found.

It seems to be an accuracy problem.
The original hatch boundaries are defined from 732 single entities.
These interconnect with an accuracy better then 1e-10 except for a gap of 0.000814 in two places.

Creating a Hatch of these entities with TA-HA is rather slow but succesfull.
After Save-Close-Open the Hatch may look different or may even be missing (=Null).

Suspected is that:
The recreation off the Hatch on load uses some other accuracy setting.
The outer boundary is not found and only some inner ones are considered as outer.

But that explains not why it looks fine after initial creation.
Nor that the outcome of a retry may vary.

Regards,
CVH

- Draw boundary (e.g. rectangle)
- Create block from boundary
- Select block reference
- Draw > Hatch

Hatch boundaries containing arcs with large radii are rendered imprecisely.

Hello. I refer to https://www.qcad.org/rsforum/viewtopic.php?p=25905#p25905 where when a block is hatched that hatch reference point is located at absolute 0,0 )where the block reference point is mapped as the reference point of the hatch and that reference point is absolute 0,0).
Best regards

Using QCAD 3.23.0.10
Win 10

- Draw circle inside other circle
- Draw > Hatch > Hatch from Segments
- Click both circles
- Right-click

The result of the tool CT2 depends on the position where the circle is constructed.

I started a drawing with a circle, center at 0,150 and gave 0,0 as coordinate for a point on the circle and got visually nothing.
After some head scratching and trying to find some error like locked layer, drawing color the same as background color and such, I found at the location of the center (0,150) a circle with radius 0.

I made the following trials, every time starting with a new drawing, entering everything with the keyboard.

Center point on result

circle

0,150 0,0 circle radius 0 at 0,150
0,150 50,50 circle radius 50 at 0,150 (should be a radius of 111.8 from 0,150 to 50,50)
0,150 0,50 circle radius 50 at 0,150
0,150 50,0 circle radius 0 at 0,150

It seems I always get a circle with the radius of the y-part of the coordinate.

Used version of Qcad is:
QCAD version: 3.15.5.0
Date: Aug 19 2016
Qt version: 5.5.1
Compiler version: MSVC++ 12.0 (2013)
Build Date: Aug 19 2016
Revision: 15ef1a13237ff8355ff590fd2e16570ef9de82a0

Given is a drawing of two concentric arcs connected at the ends. (see attached drawing Circle_from_3_Tangents_1.png)

When I try to add a circle at one end by the “Circle from 3 Tangents”-tool, it does nothing.

I also tried it with another drawing (see attached drawing Circle_from_3_Tangents_2.png) - same negative result.

I then tried drawing Circle_from_3_Tangents_3.png. Here the tool only produces outside circles and misses the inside ones.

Hope you can confirm my findings.

If I try to draw a circle between two little circles with a radius (e.g.) of 3000 the tool shows me only two possibility’s - but there are much more. If I make a counter test with the tool “2 Tangents with Point” all possibility’s are correct shown.

first pic “2 Tangents with Point” correct,

second pic “2 Tangents + Radius” incorrect,

Draw > Circle > 2 Tangents and Radius
Choose two arcs or two circles as tangential entities.

With the attached DXF file, select Draw → Polyline → Create from Segments
(O, G) and click on the complex polyline inside the circle (eg on
the top left arc). Apolyline is created with a few segments,
and one or more segments are deleted!

Different segments are deleted depending on which segment is clicked.

XP/32 QCAD 3.0.5

... after picking the first Point a wrong message appears what says:
“Warning: The two points are identical”

Drag and drop requires two clicks with auto snap if grid snap and free snap are disabled for auto snap.
- Edit > Application Preferences > Snap > Auto Snap: disable grid and free
- Drag an entity and try to position it
- First click does nothing, second click positions entity

See the steps to reproduce in the attached drawing.

1. create two new drawings
2. switch to tab 1
3. enable draft mode
4. switch to tab 2

⇒ draft mode button / menu still on (should be off)

Hi!

I just installed QCAD v3.7.5 and it works like a charm.

Then I installed the DoveTail-script (http://www.qcad.org/rsforum/download/file.php?id=623) and after that QCAD won’t start anymore.

This is the output on the command line in Linux:

Don’t know whether that is a bug in the script or in QCAD, so I am reporting it here.

The red and green lines on the attached drawing, created in 3.0 RC3 under WinXP SP3, don’t show as dashed lines. I have verified this under Linux version 3.0RC2. Opening the file in Qcad 2.2.2.0 under WinXP or Linux ver shows dashed lines.

Dots in line patterns are not displayed / printed at extreme coordinates.

I use architectural units everyday in QCAD and would appreciate being able to enter feet and inches from the “command line” for convenience and accuracy.

I have been entering “calculations” to arrive at the distance values (i.e. 10*12+6.125 = 10’-6 1/8”), but this method is time consuming and prone to input error.

I would like to see Acad’s architectural distance method implemented in QCAD. This entry method would replace the “calculated” entry with (as an example): 10’6-1/8.

Command Line: Next point: 10’6-1/8
The <’> mark triggers a 12 times multiplier for the proceeding number,
the next number is the whole inches and
the ↔ is a separator that adds the fraction to the whole inches before it.

Thanks for considering this feature request. I’m certain that many QCAD users in the Architectural, Mechanical, Electrical and Construction professions wold appreciate this convenience (especially those moving past Acad).

Block with hatch scaled with factor in X different from factor in Y leads to problems if contour contains arcs (which cannot / are not scaled disproportionally).

This manifestation happened after I had loaded an existing drawing, made modifications, then used print preview and adjusted the scale to fit the paper.

The file was closed. Upon reopening lines designated as .25mm were unusually thick such that two lines 2mm apart appeared as one solid line. Placing the cursor over the line showed it was comprised of two lines.

Changing the properties of a line to make it thinner did not help with one exception and that was to set the line thickness to default, when the two lines became visible.

Drawing created with a previous QCAD version has issues to be correctly displayed in the current snapshot.
e.g. drawing opened in QCAD 3.23.0 - works flawless.
same drawing opened in QCAD 3.23.4 - has problems to show inserted blocks correctly.

Start up QCAD, *do not pan or change zoom level*. Draw a Ray or an XLine so that it (its extension, in case of Ray) goes through (0,0) and is 45 degrees (ie. draw y = x).

In this case and this case only, the Ray/XLine will be reduced to a line segment exactly between its start- and end points. It seems that this is only a visual artifact: if you pan or zoom now, the segment will be restored to what it’s supposed to be.

If you change zoom/pan back to what it was at startup, the artifact re-manifests itself.

Some flashes indicate that there are some other positions, not just the initial view, that also bring this up (ie. if you pan to a specific position, artifact appears again; it’s probably deterministic, too, but I can’t seem to be able to stop at that exact point while panning so I could count or something).

Blocks disappear (or their content does) after creating again with the same name. In attached file:

1) Created cirle
2) Select circle, BC, select center, name is ‘testblock’ 3) Repeat 2) – circle is now gone
