QCAD Bugtracker

Andrew,

Encountered with snapshot 3.26.4.9
On both a 32bit win7 and a Linux machine.
But probably not related to version nor OS.

The calculated area centroid position for a self-intersecting shape is invalid.
Therefor polylines and splines are checked for their self intersection nature.
Polylines with line segments require a tolerance of 1e-6.
For polylines with arc segments there is no easy to formulate value.
Reverted to something less strict than the arc connect tolerance: 1.1e-3
Refer to: https://www.qcad.org/rsforum/viewtopic.php?f=30&t=8526&p=34056#p33694

RSpline.getSelfIntersectionPoints() has no tolerance value.

Some perfect valid spline shapes fail this test.
Not related to the XP spline approx tolerance preference.
Related to orientation, try the failing shape when reversed in situ.
Related to their position in the plane, see translated examples.

Reproducible with control point splines.
Reproducible when rotating the shape.
Such failing closed splines can be hatched and an area centroid is returned.

CVH

PS: Got a notice posting this:
“Notice: Trying to access array offset on value of type bool in /home/qcadch/public_html/bugtracker/scripts/details.php on line 222”

When try partly print multipage , all pages will be printed.
in my this project i reserved 5*10 =50 pages, but so far have made less than 10 ready, which I wanted print out, it always start print all 50 pages, no matter How i try choose.

Points in hatch patterns are exported as empty path elements in the exported SVG.
Therefore, the hatch patterns “DOTS” and “AR-SAND” are not visible in the exported SVG.

I am using QCAD/CAM version. Since I installed this version of QCAD that I bought recently, I have a problem with the keyboard settings. On the QCAD application, the keyboard is set to English, while it is set as Swiss French on the system level.

To reproduce:

1. File – New
2. Create a new layer (layer 1)
3. Draw an horizontal infinity line
4. Duplicate “layer 1” (layer 1 Copy)
5. Hide “layer 1 Copy” 6. Try to select the line in “layer 1”

What happens: It’s not possible to select the line in the visible layer (layer 1) if the line is present in the duplicated layer (layer 1 Copy) and that layer is either hidden or locked.

Expected: It should be possible to select the line, as the overlapping line in the other layer is hidden/locked .

Hello,

I must have something set up wrong, prints blank both on printer and pdf....

Andrew,

With an CW ellipse Arc > 180° the GUI method info Arc/Circle/Ellipse (IC) in segment mode throws an exception:
Uncaught exception at :scripts/Information/InfoArcCircleArea/InfoArcCircleArea.js:210: ReferenceError: Can’t find variable: remainSectorArea

Rather a complex way to get the area of an ellipse arc segment.

There: area = majorR * minorR / 2 * (sweep - Math.sin(sweep)).
- where majorR, minorR & sweep can simply be sourced from the ellipse arc shape/entity.
- where the area is signed ... +CCW, -CW

About identical as for an arc segment.

For an (ellipse) arc sector one would only need to add/subtract
the area of triangle |StartP-CenterP-EndP|

Regards,
CVH

Please refer to:
https://www.qcad.org/rsforum/viewtopic.php?f=32&p=35080#p35080

Can this be implemented as a GUI metod?

Some drawings, particularly with a lot of angles, results in a very decimal number.

It would be great to have the option to change the precision of individual dimensions when necessary.

Currently, the precision is universal in the drawing.

What I’m currently doing is leave the precision to zero decimal cases and manually inserting decimals when needed, but it results in a dimension with no “Auto” label, that may result in wrong dimensions on the workflow, especially when editing the project. The dimension labeled manually will not change, so it can cause errors.

As a heavy mechanical drawings user, it would help a lot to have an option to select similar entities while working on QCAD.

In the flow of the work, sometimes I need to make some changes in all similar entities of the drawing.

The Select Similar works selecting all the same items with the same layer on the drawing.

Example:

I have a drawing for other company and I have to make a massive layer changing to my own layers.

I select a line and circles with a box selection, activate the Select Similar command and the QCAD instantly selects all lines and circles(no matter length) with that same layer. I can then change the layer of all of them instantly.

Or if I have a peace with a lot of circles, that aren’t in a block, in one time I want to change the layer or diameter of all circles in a certain part of the drawing.

I select the circle and activate the Select Similar command, the QCAD automatically selects all circles with the same layer and I deselect the circles that I don’t want with a box desselection and change the layers of them, or the diameter via properties.. and etc.

There is a workaround, that would be working with activating or deactivating layers, but the select similar would be a faster shortcut.

Thanks Andrew and team!

Hello, I am not sure if this is a bug or if I use it wrong way. But when I create block with two identical block attributes everything look ok. I Can insert it to drawing, set the value (both will change). But when I use “Synchronize attribute (UY)”, only one will stay. It would be fine if both would stay. But I understand that you probably use tag as identification.

To reproduce the problem just open the attached file and press UY

Version QCAD 3.26.4.7 / Windows x86_64

Existing drawing:

1. e.g. flange.dxf loads with no fills (solid hatch) for arrows,
2. New dimension are also without arrow fills.
3. This existing drawing has Text above line! Setting Drawing Preferences / Dim to “Horizontal text labels” will alter Text to be Horizontal BUT also open a gap for the text which is a separate setting (Text above dimension Line). Undo doesn’t works on this properly - used multiple times will even change the dim color which wasn’t changed in this operation.

New drawing:

1. Same test scenario - same issue.
2. Dim settings = Horizontal text Labels ticked, Text above dimension Line ticked produces a dim horizontal orientated with a gap instead to put the text above the line

I have selected version 32 as the default file save format but new files default to version 27 when saved

The layer properties dialog has a drop down that lists all of ones layers. The dialog itself can be stretched horizontally, but the drop down doesn’t stretch with it. Because of this design element overlooked, it is near impossible to read longer length layer names. I have attached a screenshot that illustrates the problem.

Trimming With AX slows down with many text entities.
Seeing the same lagging with D2 on Circle entities.

Also seen on Windows 10 Pro 3.26.4.0
Forum topic: https://qcad.org/rsforum/viewtopic.php?t=8729

Attached files:
TrimAuto_1.dxf ... 11 entities ... trimming instantaneous
TrimAuto_2.dxf ... 11 entities + 1936 LINES ... rather instantaneous
TrimAuto_3.dxf ... 11 entities + 1936 ARCS ... less than 1 second
TrimAuto_4.dxf ... 11 entities + 121 TEXT ... over 3 or 4 seconds
Slower for larger Arc / Circle

The questions here are:
Should AX trim at text entities?
Can this be optional?

Polyline from segments (OG):

The StatusTip reads:
“Create polyline from existing, connected line and arc segments”.

The CommandPrompt and LeftMouseTip both read:
“Choose line or arc segment or polyline”.

The tool let us pick 4 types of entities:
... A line, an arc, a polyline and also a spline entity.

If the picked entity is not one of these 4 types we get the warning message:
“Entity is not a line, arc or polyline.”

The tool prepends/appends 4 types of entities:
line, arc and polyline entities and also spline entities approximated by arcs.

Wouldn’t it be more appropriate if the tool mention all 4 types?

e.g.
StatusTip:
“Create polyline from existing, connected lines, arcs, polylines and splines”

CommandPrompt, LeftMouseTip:
“Choose line or arc segment or polyline or spline”

Warning:
“Entity is not a line, arc, polyline or spline.”

See attached file:
- The 9 center snapping points of the 24 bulging segments are all presumed to be incorrect
- For some segments the center snap is outside the arc shape from a bulging segment
- For some segments there are 2 solutions

Affects arc, circles, ellipses and polylines with segment length < dash length

See attached video.
Open file, copy block reference, explode original block reference, edit attribute of inner block in exploded block reference, save file, reopen file.

Caused by missing linear scale property of ordinate dimensions.

Open attached file, edit “outer” block in-place, click Save and close. The attribute of “inner” block disappears.

Version:
3.26.4.5 (3.26.4.5)

Autocad requires that all overrides are written to DXF/DWG, not only those that are actually different from the dimension style.

I noticed a bug while editing blocks in place. When I opt to edit in place, most of the surrounding blocks fade out properly, but some don’t. Although I can’t edit them, as they are not faded, It can be tricky to identify what is in the current block or not while editing a bigger assembly.

Another suggestion is to add a keyboard shortcut command to the “save and close”.

Otherwise, this is a fantastic feature that really enabled me to buy the QCAD and start using it professionally. In place editings are a key feature for my projects and drawings.

Thanks in advance.

IMG 1 shows my drawing

IMG 2 shows a block being edited “not in place”

IMG 3 shows a surrouding block being edited “not it place”

IMG 4 and 5 shows the in place edit of the block shown in IMG 2 and the surrouding blocks not being properly faded.

QCAD/CAM 3.26.4 crashes at startup (just disappears) if setting “EnableHierarchicalLayers” to “false” in QCAD3.ini (Section: [LayerListPro]) on Windows.
Tested fresh installs on several computers, including Windows 10, 7, XP. 32 Bit and 64 Bit OS and QCAD/CAM.
After removing “EnableHierarchicalLayers” or setting “true” QCAD/CAM starts up normally.

So user without knowledge of finding/editing .ini-file will lock himself out by disabling “Application Preferences > Widgets > Layer List > Enable Hierarchical Layers”

The parsing for the -min-lineweight option of dwg2svg is broken, only -w or the undocumented -minlineweight options work.

This is due to a typo in the Dwg2Svg.js script around line 225:

      properties["minLineweight"] = getArgument(args, "-w", "-min-lineweight");
      if (isNull(properties["minlineweight"])) {
          properties["minLineweight"] = getArgument(args, "-w", "-minlineweight");
      }

This should be:

      properties["minLineweight"] = getArgument(args, "-w", "-min-lineweight");
      if (isNull(properties["minLineweight"])) {
          properties["minLineweight"] = getArgument(args, "-w", "-minlineweight");
      }

Note the case minlineweight vs minLineweight.

This has the consequence that the value parsed form -min-lineweight is always replaced with the value from -minlineweight, which is usually undefined.

Since the short option -w is parsed in both cases, it is not affected from the bug.

This happens only when using “save and update” and then “close”. “save and close” works ok. See in video
Buttons for adding and removing from working set seams buggy for me when I played with them for a while (some block references completely disappear form drawing). But I am not able to describe this behavior.
