Task Description

In my example I can’t draw a circle with circletangent2 if the defining point is on one of the defining tangents. The tangency is lost when I try to do this.

I attached 4 screenshots: TheExample.png, TryingPoint1.png, TryingPoint2.png and The_Point_Isn’t_On_The_Tangents.png.

2048QCAD (main)Bug ReportVery LowMove / Copy to current layer fails when reference point...Assigned
0%
Task Description

QCAD 3.24.2 / macOS x86_64 10.14.6

Starting with empty doc:
1. Draw any object (e.g. a rectangle) on layer 0.
2. Create new layer (”1”) with color, say yellow.
3. Select new layer
4. Select new object
5. Modify → Move / Copy
6. Click reference point
7. Click target point same as reference point
8. In “Move / Copy Options” dialog, select “Delete Original” and check “Use current layer and attributes.” Click OK.

The moved object stays on the layer it was previously on. Using “Move / Copy” as a quick way to move a selection between layers is not useful even though it appears to be the recommended way in a Google search.

Note: if “Keep Original” is selected instead, the copied object is placed on the current layer and the original object remains on its layer, as expected.

Note: if the target point is different from the reference point, the moved object is placed on the current layer as expected.

There are other workarounds too, cut / paste with “To current layer” checked seems to work, as does chaging the layer in the Properties Editor.

How to reproduce.

1. Create a text field with some non-english words in the upper index. (see attached pic1.png)
2. Save the project and close QCAD.
3. Run QCAD and open same project.

Polyline arcs with Width = 2R render as circle segments rather than circle sectors.
As Non-reversed arcs these don’t explode.
As reversed arc these explode to a single arc rather than a circle sector contour.

Arctic_Eddie reports failing CAM offset at exactly these points !!!
Reported is a faulty arc with radius of over 360,000mm.
- I can not reproduce this under QCAD working further on the Polys with NaNs.
- However the direct offset of such controlpoint Splines is erroneous.
(see file in post 30902)

Arctic_Eddie reports arc radii of over 10,000mm.
- These don’t seem to be faulty.
- I agree that BiArc fitting should be bound to a lower and certainly to an upper limit.
- That should be huge otherwise faint curvature is represented by many
wobbles or too quick by straight lines.
(All this, keeping in mind that QCAD doesn’t return the optimum fitted BiArc, see: https://www.qcad.org/rsforum/viewtopic.php?t=4859)

1 Task Description

I have set the grid/snap value to X=.0625 Y=.0625 on all 4 viewports.
When zooming in and out the grid/snap scale changes from .0625 to 3.90625. at this point the grid/snap points differ,
This causes a variation in the grid/snap reference points lending to drawing errors.

example
When I use the grid settings defaults .01, when zooming in and out, the grid/snap scaling doesn’t seem to have this issue.
Other values do, See below.

set value first zoom second zoom next zoom

	point		point		point ...

Why is there a squaring of the original set value? Which then becomes a new zoomed grid/snap value?

When using the vertical line tool, you can enter a length value in the options toolbar, then place the line. If you want to change the length, you just need to enter a new value and the length field will update.

I could not seem to duplicate this behavior with the horizontal line tool.

I noticed the ALT “D” does not cycle through the headings Draw & Dimension in the same way.
ALT “M” cycles though Modify & Misc or ALT “S” cycles though Select & Snap.

2391QCAD Community EditionBug ReportLowFix Dark Theme for LinuxAssigned
0%
Task Description

The dark theme for Linux is broken:

- Some icons have dark background (expected) and black foreground color (that should be replaced by white of very light gray)
- Some icons have light background (not cohesive with the theme).
- The command history shows dark blue font on dark gray background.
- The grid’s ruler shows black font over dark background for the numbers.
- The icons folder is missing in the GitHub repository, but other themes have that folder.
- The general icons (open, save, and so on) are not dark theme friendly. A better approach for maybe all the themes would be to use something like the breeze icons pack for LibreOffice, and it will have the added benefit of making the app look more modern.

The icons issue is the biggest problem. They should probably replace the black color for white or very light gray. Even the red accent color is not ideal for dark themes, is not the main issue.

Attached is an image that show the problems and another that shows LibreOffice with the Dark Breeze theme for reference.

2405QCAD Community EditionBug ReportLowDimension scaling not workingAssigned
0%
Task Description

I’m using QCAD Community Edition 3.27.7 on Windows 11.

When I started my drawing, I was able to change the size scale factor of (existing) dimensions using “Edit/Drawing Preferences/Dimension/Dimension Settings/Size scale factor”. However, suddenly this feature stopped working and now I cannot switch the dimension scale factor any longer.

I used this feature to be able to adapt the scale factor of the dimensions when printing in different scales.
I.e. all my drawings are in “original” size but when it comes to printing, I print some parts in scale 1:2 (in which case I used to set the size scale factor of the dimensions to 2) and some parts in scale 1:10 (in which case I used to set the scale factor of the dimensions to 10). Using this procedure, the dimensions have the same size (font size, arrow size, gaps etc.) on both drawings.

I have attached the drawing, that shows the described issues.

2406QCAD (main)Bug ReportLowSVG Export incorrect on blocksAssigned
0%
1 Task Description

When using SVG export on a drawing with a block defined, the export is incorrect. Arcs are drawn incorrectly and parts of the block are missing. If that block is exploded, the SVG export is correct. Attached is a block on the lower left and the same block on the lower right after explode. Also attached is the resulting SVG file.
This is not always the case. Some blocks are correctly exported to SVG. The upper row is again a block on the left and the same block exploded on the right. It exports properly.

2415QCAD (main)Bug ReportVery LowIssues with OffsetBothSidesAssigned
0%
1 Task Description

Andrew,

I can’t find any documentation concerning OffsetBothSides under Misc .. Modify.
It is not listed in the QCAD features nor in the changelog.

There was a Feature Request FS#1130 for this, I think you might want to close that as being implemented.

The tool asks for a Line, Arc, Circle, Ellipse, Spline or Polyline.
It also seems to act on shapes that can be exploded to such entities like Text, Dimension and Hatch entities.

There may be many ‘Result loop not closed’ or ‘No offsets possible’ warnings when hovering over entities on a drawing.
The preview may be partially, one or two sided and even two sided partially and closed with semi-circles.

I only successfully created a dual offset for open Splines, open or logically open Polylines.
All other attempts result in a single offset at the indicated side.

There are the usual exceptions for Polylines with arc-segments but that is related to small arc segments and being tangentially connected.
Only tested it on a Win7 platform.
I don’t suspect that version 3.27.8 includes a fix for that ... ;-)

Regards,
CVH

2440QCAD (main)Bug ReportVery LowHatch from Segments > False positives open loop warning...Assigned
0%
1 Task Description

Andrew,

Most probably not related to OS or QCAD version.

When hatching an area with Hatch from Segments (HS) there might be false positive warnings on open loops.
It seems that this is related to the orientation of the indicated segments and the order of selection.
The real problematic position is not always the first that is reported.
Loop count is increased even if it is a single loop.

Included a basic test drawing to replicate these.
Further details to replicate the issue are in the file.

CVH

In the included screen grab below, left is when drawn cubic, closed periodic, from 4 points.
Right is when the file is re-loaded.

It is hard to select the incorrect shape when pointing near it ... Probably it is referring to the correct internal shape.
After drawing it explodes to a Null length polyline with 2 identical vertices.

I can’t include the error in a file as it reverts on re-load.

The same issue exist for quadratic, closed periodic, from 3 points.

1 Task Description

Andrew,

Referring to this forum post:
https://www.qcad.org/rsforum/viewtopic.php?f=74&t=10152

With radii 1341.35667735 and 26 the relative tolerance is 0.00683678 and exceeds the former used fixed tolerance of 1e-4.

These arcs will then be considered to be tangent and the intersection point is 0.31024 units to the left of where we expect it.

Implemented: https://github.com/qcad/qcad/commit/77ae3e4518cc34f178779d2d2c724adcf80c229d#diff-dcc4e31eaeaed5a047f65dbce4ddda4bcd4d604e9e1005ee8481ded273768449

Updated: https://github.com/qcad/qcad/commit/071b60acd1176e6301bf6b6fcf716684221a97e8#diff-dcc4e31eaeaed5a047f65dbce4ddda4bcd4d604e9e1005ee8481ded273768449

I had already expressed my reserves on the relative tolerance but that was already a better solution for small arcs:
https://www.qcad.org/rsforum/viewtopic.php?f=33&t=8775&p=34907#p34907

We could limit the tolerance by:
A- The smallest of the fixed and the relative.
B- A relative tolerance based on R2 there circle 1 is forced to be the larger one.

This will never account for the position in the plane.
At a certain point the tolerance will be less than the accuracy/certainty of the values.

Regards,
CVH
