Win 7 32 bit QCAD 3.20.1

Ofsset of a base-line with arcs results in massive ammount of errors.
Most of them occur as a cluster of very tiny segments and are part of the offset. (zoom far in at the red circles)
Mostly they occur where the offsetted arcs should merely be trimmend pairwise.
Some occur as detached entities or as detached strings of entities very near the offset (strings not documented).
Spooks occur at opposite site when base-line is not closed.
360° curls can occur with R = Offset.
Null-entities may occur (not documented, hard to find and not able to copy).

The base-line is checked and sound and has mixed tangentially or not tangentially connected arcs.
Offsetting the mother base-line of the base in the file has similar effect but not all and/or different ones.
Also encountered with offseting polys from fonts.
Used to define pocket paths for CNC.
Detected because the CNC driver will not accept Self-crossers, Null-entities or open ends depending on the settings.

Work arround is to explode and select small entities but this does not solves the issues.
1) Choosing the tolerance large enough will detect small segments that should stay.
2) Recombining will generate new ones at the place where the main segments remain crossed.
Cleaning up the paths is a daunting process with some thousand segments for several offsets.

I assume this has an infuence on the CAM part of QCAD too unless the offset method is different.

‘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’.

(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.

Macbook Pro 15”, OS X 10.13.6

Regarding to an observation by the forum member Horst1803
http://www.qcad.org/rsforum/viewtopic.php?f=92&t=5725

The ruler functionality is compromised by Graphics View / Grid settings.
To show the full Ruler functionality “Automatic scale grid” has to be activated. I think that is not intended behavior.

Case: Appearance / Show rulers = activated

Application Preferences / Graphics View / Grid

on - Automatically scale grid
on - Automatically scale meta grid
off - Solid grid lines
= Rulers visible
= Graduation visible
= Labels visible

off - Automatically scale grid

Ij window CAM Configuration output unit appears as inch instead of mm. All parameters are in option
when create a nc file,units are in inches not in mm. unsuable and not possible to change

1) Open the attached dxf file
2) Right click on “vne_vent_odvod_ec_3f” block in Block list and select Copy block
3) Choose name
4) Insert reference of this Copy block to the modelspace
5) Save the file
6) Close and reopen the file

RESULT: Attributes of block references included in the original block are missing in the copied block.
Immediately after insertion of the copied block I can see in the property editor, that block reference attributes are not “conected” to the block reference, but they are still visible. They disappear when the file is reopen.

Alternative way I use to copy this kind of blocks without error: Open block I want to copy, Select all entities, reference copy of them, paste to modelspace, select them in modelspace and choose create block.

In a the modelspace I have a block reference of a block(parent), which includes block references (with attributes) of another blocks(child). Than I select this parent block reference and choose Explode. The result is, that the child block references have visible attributes, but they are not connected to the block reference anymore (I can not see them in property editor when the child block is selected). Than when I choose synchronize attributes, new attributes with default values will appear.
I am not sure it his is a bug or expected behavior of the Explode feature.

If it is not a bug, I would like to have new Extract feature, which would copy the content of the selected block reference and immediately insert it exactly to the same place (attributes would be still connected to child references) Extracted block reference would be than removed. Optionally, it could delete the block definition if it is not used anymore in the drawing (but there is already Block Purge feature which will do this).

Drawing and PrintPreview are consistent, but printout differs : rectangle missing (bottom right), line missing (bottom green line) - see att. Error can be reproduced, after saves and restores.
A VERY elementary WYSIWIG-problem....

After I remove the .dll files from the pro trial version, right click stop working on Windows 10.
I went a little further to try identifying which of the 5 files specifically causes right click to stop working, and I found that it is qcadproscripts.dll. The presence or absence of the other 4 dll files that make up the pro version has no influence on this behavior.

Wrong orientation is returned for polylines with large arcs (>180d).

Hi guys,

I’m trying to create an spline to a complex library component, but it seems splines are not working properly. I would appreciate some help. These are minimum scripts to demonstrate the problem:

Example 1:

include("scripts/simple.js");

function TesteSpline() {
}

TesteSpline.init = function(formWidget) {
    if (!isNull(formWidget)) {
        TesteSpline.widgets = getWidgets(formWidget);
    }
};

TesteSpline.generate = function(documentInterface, file) {
    return TesteSpline.criarCorpo(documentInterface);
};

TesteSpline.generatePreview = function(documentInterface, iconSize) {
};

TesteSpline.criarCorpo = function(documentInterface) {

    addSpline([[0,0],[20,30],[100,100],[110,120]], false); // it doesn't work :-(
    addLine(0,0, 100,100);  // it works!!!

};

Example 2:

include("scripts/library.js");

function TesteSpline() {
}

TesteSpline.init = function(formWidget) {
    if (!isNull(formWidget)) {
        TesteSpline.widgets = getWidgets(formWidget);
    }
};

TesteSpline.generate = function(documentInterface, file) {
    return TesteSpline.criarCorpo(documentInterface);
};

TesteSpline.generatePreview = function(documentInterface, iconSize) {
};

TesteSpline.criarCorpo = function(documentInterface) {
    var addOperation = new RAddObjectsOperation(false);
    var doc = documentInterface.getDocument()
    // Spline
    var cavaData = new RSplineData();
    cavaData.appendFitPoint(new RVector(0,0));
    cavaData.appendFitPoint(new RVector(10,10));
    cavaData.appendFitPoint(new RVector(30,30));
    cavaData.isClosed = false;
  
    // It doesn't work
    var cava = new RSplineEntity(doc,cavaData);
    addOperation.addObject(cava);

    // it works
    var textData = new RTextData(new RVector(2,10),new RVector(2,10),0.4,0.4,0,0,0,0,1,"Hello","Arial",false,false,0,false);
    addOperation.addObject(new RTextEntity(doc,textData));

    return addOperation;
};

Hallo Andrew

Beim Skalieren(SZ), Rotieren(RO), Spiegeln(MI) beendet sich QCAD, wenn gespeichert wird. Änderungen werden nicht gepeichert.

When scaling (SZ), rotating (RO), mirroring (MI), QCAD ends when it is saved. Changes are not saved.

Polyline’s areas don’t shows own property in Property Editor

This code was executed in the Script Shell window. Then the program is failing of and closed.

a = addLine(0,0,100,100);
lengthen(a, true, 50); // success
lengthen(a, true, 50); // FAILED!

Whilst using qcad professional today, I have lost hours waiting for the to start working, as it keeps crashing with every command/drawing a line/editing a shape.

Hopefully you can look in to this and advice?

wrong objects are selected while selecting region with mouse.
Actions:Trying to select small rectangle area using mouse while holding left mouse button. (ScreenShot_1.jpg)
Expected result: only objects inside selection rectangle (text, lines, rectangles) are selected.
Factual result: objects inside selection rectangle are selected as well as other objects which are farther away (marked with purple arrows in ScreenShot_2.jpg)

When I run bbox with the attached file I get inconsistent results if I run it 6 or 10 times.

Sometimes the size is 448979.2349223149/310815.2964427199 (it thinks that there is an object at 0,0)
sometimes it is 338.0789223148604/302.31644271989353 (this is what I think is correct)

To reproduce:

1. Draw a rectangle.
2. DH, draw a dimension (the base dimension).
3. Move that dimension’s text to a new position.
4. DC, continue that dimension.

The text of the continued dimension will show up on top of that of the base dimension. Expected behaviour would be that it would show up on top of the continued dimension (standard placement).

Please see attached pic.

Rectangle with Size (RS) doesn’t update the Fill, RoundCorners & Radius settings shared under the [Shape] header in QCAD ini.

Explained as group synchronization while the Polygon methods have more settings in common, although not shared.

In the summary there are more minor issues listed.
All have a bar in the Options Toolbar that disappears after the first is drawn.

I rather would opt for all individual settings ...
... or all grouped.

Referring to the grid they are rendered about 0.0002 long.
They are in the order of 5e-15 and less or simply zero long in this case (<1ULP).

In the file provided one would expect *VARIES* in the property editor under custom properties when selecting 2 or more entities.
The key list is reduced to what keys are common to the multiple selection. (Here 3)
The values displayed are inconsistent depending the selection.

Select All » 3 custom properties of line 3
Select the 3 vertical » 3 custom properties of line 2
Select the first vertical and the diagonal » 3 custom properties of line 1
Select all but the first vertical » 3 custom properties of line 3

Andrew,
This is bugging me for over a year now.
I filed it as a feature request as it is dismissed twice as a possible bug on the forum.
In both cases the advice is to only use Specific Scale 0 for Leaders.
(... and adapt all other dimensions to that)

I am aware that an arrow head has to fit twice on the first leg of a Leader Entity.

The size is set global in the Drawing Preferences under Dimension Settings: ‘Text Height’.
Under Dimension Settings, there is also a global ‘Size scale factor’.
And every dimension entity has a Specific Property called ‘Scale’ that supersedes this global ‘Size scale factor’.

Proof of concept: Dim size 5 and for any regular dimension.
1) Size scale factor 1, Specific Scale 0 » text height & arrow length = 5 units.
2) Size scale factor 2, Specific Scale 0 » text height & arrow length = 10 units.
3) Size scale factor 2, Specific Scale 1 » text height & arrow length = 5 units.
4) Size scale factor 1, Specific Scale 2 » text height & arrow length = 10 units.
5) Size scale factor 10, Specific Scale 0.5 » text height & arrow length = 2.5 units.
6) Size scale factor 99, Specific Scale 0.1 » text height & arrow length = 0.5 units.
→ Obvious is that the ‘Specific Scale’ supersedes the dimensions ‘Size scale factor’.

Those two last Leader arrows (2.5 & 0.5 long) would definitely fit twice on an 8 units long first Leader leg! And they do perfectly while drawing them.

However, the arrow will be reset when the file is saved & loaded.

For case 5 the first leg has to be (2 times 5×10) 100 units or over so an arrow 2.5 long remains on save (=40 times). In the absurd case 6 that would be (2 times 5×99) 990 units or over for an arrow only 0.5 units long (=1980 times).
Verfied and true.

It seems that on save/load:
The Specific Scale is not taken into consideration while evaluating ‘At least twice’.

Apart from that they render fine when first drew.
And reappear when setting the arrow back on again after load.

Regards,
CVH

I just updated my QCAD to 3.26.2.0 (3.26.2) version and lost the hability to edit block attributes of my sheet or in any other block.

I tried to save as the drawing and the problem persists.

When I open the block, the attribute is there and is all set in the Specific Properties, but when I exit to the Model Space to edit the Attribute text, the created attributes don’t appear on Specific Properties tab.

The use of block attributes in sheets, balloon or any block that contains text is very necessary.

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

Can this be implemented as a GUI metod?
Two feature requests: See  FS#883 ,  FS#1449

Throws me out of QCad consistently:

1. Have a polyline selected.
2. Click partial polyline along selection and click the first point on the polyline.
3. Hit escape key or similar to exit the tool.
