When I’m drawing inside a layout block the offset tool picks up lines from blocks that are hidden.
It is not happening with all the block.

Insight is the best way to get better ...
... but the rest is more an odd choice of tools for this kind of task ...

Again, the MISTAKE was by accident, not intended, in a flick of the wrist ...
I didn’t change the trimming method, I simply forgot to ... only once.

The ‘undo’ of my incompetent MISTAKE didn’t returned to how the situation was before I erroneous trimmed with TM.
I was simply undoing my erroneous action.

Documented it in 4 quadrants.
For this, 4 times on purpose, and not as a consistent ‘odd choice’.

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.

There is also still the faulty rendering with Z not zero

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)

Same drawing zoomed in and out in 3.20.0.0 doesn’t show this effect - works just fine.

Hi Andrew

In QcadCAM when using the new Themes or User Created Themes the Layer and Block Tabs Appear to be reversed in East and West Positions.
I have discussed this with forum user PeteVick and he cannot reproduce this behavior in Qcad Pro... he suggested submitting this bug report.
I didn’t notice this until he pointed it out and don’t expect it to be high on your list of things to do..

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 ...	

0.01 0.1 1.0 10.0 ...
0.02 0.04 0.4 4.0 ...

0.0254 0.64516 6.4516 64.516 ...

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

Andrew,

In the attached dxf:
Besides that it is clear that duplicate vectors are not filtered ...
Where a segment is crossing in another node a non valid node is returned as self-intersection point.
Seems to be unrelated to CW/CCW or tolerance.

Where 2 nodes coexists 4 duplicate vectors are returned.

The tool “Clip to rectangle” / “Cut at Area Boundary” tool used on an area with lines and arcs will partly complete arcs to circles.

How to reproduce the bug:
1-open a new file
2-select text tool, simple text(one line,no formatting) and alignment in base-left
3-write some text in somewhere position in the draw, repeat this in others positions
4-save the file in .dxf R15 [2000/LT2000] (dxflib) format
5-close Qcad
6-open the saved file, the writhed text lose original position and now all the text have 0,0 position

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

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

Andrew,
For more detailed description please refer to:
https://www.qcad.org/rsforum/viewtopic.php?f=33&p=40081#p40081

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.

CVH

Referring to this forum post:

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

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.

It took me a while to find the source of a certain freak bug I encountered.
I used the RLine.isParallel(RLine) as a test for knowing if line segments were parallel or not.

Andrew,

When switched to French I detected a typo in the drop down box for Lineweight.

Weight 2.11mm is listed as 1.58mm {2.11m?}
https://github.com/qcad/qcad/blob/master/ts/qcadcore_fr.ts#L1228-L1229
Also see attached image file.

May I ask why only ISO types have a comma instead of a point in French.
The use of a comma is uncommon in the Property Editor even when that is the native decimal separator.
I also detect an extra space between the value and ‘mm’ and that only for the ISO types.

This only occurs in:
https://github.com/qcad/qcad/blob/master/ts/qcadcore_fr.ts https://github.com/qcad/qcad/blob/master/ts/qcadcore_pl.ts https://github.com/qcad/qcad/blob/master/ts/qcadcore_pt.ts

Upon activating the Polygonal Area Tool either by clicking on the toolbar or by the IR keyboard shortcut the tool will persistently draw a polygon without clicking anything. This happens with the mouse and the trackpad on the MacBook Pro. This was happening in 3.29.3, and then after I upgraded to 3.29.4. The MacOS version is 14.1 Sonoma.

Andrew,

The _DatumFilled Block used by Datum entities (DT) is considered as not used and is purged by Purge Unused Blocks (BP).
There is no block association for these special types of arrowheads in QCAD.

After purging the Datums are not immediately updated but the special arrowheads will eventually disappear. Adding new Datums will not fix that.

Not problematic because the _DatumFilled Block is re-created on save/reload when Datum entities exists. Datums are updated.

Probably not OS or version related.
Related forum topic: https://www.qcad.org/rsforum/viewtopic.php?f=89&t=10694

Best solution would be to support different types of arrowheads and all related:

implement

it would be ideal to be able to have the option to autohide the side panel to increase the visible drawing space when working on a small screen.

The modify stretch tool wants first and second corner, start and end point, then starts afresh. When I turn on restrict horizontally eg to align two points between start and end, the restriction sticks and I have to call restrict none, to be able to perform the next iteration, set the first corner then.

So, in the quest for a comfortable user interface, it was nice, if the modify stretch first/second corners parameter setting was not affected by current restrict/ortho etc. settings. Actually, that does not make any sense at all anyways, does it, a rectangle is defined by two degrees of freedom, isnt it?

See:
http://www.ribbonsoft.com/rsforum/viewtopic.php?t=1867

Apparently this was possible in QCAD 2 due to the default behavior of Qt.

Hi,

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.

It would be nice if one could change this behaviour / select the symbol of points.

This is a double post of http://www.ribbonsoft.com/rsforum/viewtopic.php?p=5870#5870 as suggested there.

I would like to get a shortkey like ‘+’ to rotate text at 90° clockwise.

Since this is not supported by Qt anymore, this would likely have to be implemented from scratch.

Eine oft Hilfreiche Zeit/Klick sparende Erweiterung wäre eine “Total” Option bei dem “Lengthen” Tool.

Aktuell ist es mit dieser Funktion möglich ein Element zu verlängern oder zu verkürzen um den Amount X. Der Referenzpunkt (von welchem Ende) kann bestimmt werden.

Die Erweiterung die ich mir wünschen würde wäre auch ein “Total” um ein Element auf eine bestimmte Länge zu bringen ohne einen Taschenrechner benutzen zu müssen. Referenz (welches Ende oder Mitte) sollte (muss) dafür wählbar sein.

Die Funktion “Property editor” stellt bereits über die Geometry Eigenschaften die Möglichkeit zur Verfügung einen “Total” Wert zu manipulieren. Leider bin ich aber hierbei nicht in der Lage zu bestimmen welcher Element Referenzpunkt dafür benutzt werden soll. Könnte ich die Referenz wählen (welches Ende oder Mitte) wäre auch dies dann durchaus akzeptabel

To have a ‘clean up ' tool to:

- eradicate duplicate lines
- eradicate stray points
- remove empty layers
- remove unused blocks

Perhaps with an initial dialog which allows the user to choose what they want to clean up.

Input:

1. X axis min/max or choose line (?) or center (for polar functions)
2. function: y = f(x) / polar function: r = f(a)

Output:

Task: If I like to make a hatch and the contour isn’t closed I get a Grey circle Info where the contour isn’t closed. Nice!

But ..... I have this Info only for ONE not proper connection and only for the moment when the mouse pointer is over the Hatch Tool Symbol.

If I have to zoom into the Problem - I will lose the Info where the problem is

To get the “Problem Info” back I have to select it again - but for that I have to zoom out ...............

It would be nice to have this “Problem Info” longer in the drawing - maybe until I solved all problems.

And it would be nice to have ALL Infos for not connected lines at the same time. It is not really helpful to repeat this function 20times if I have 20 connection problems ... ;)

To re-introduce Tile and Cascade window options like as before in QCAD 2.2.2.

Hi,
this is a usability feature request:

If you want to move an object relatively to any point (e.g. by entering @x;y in commandline) it does’nt make sense to enter a starting reference point. Of course this is possible by clicking to any location on the screen. But it’s difficult to change between mouse and keyboard so often.

It should be possible to enter a “don’t care” or “any” reference point by pressing a keyboard shortcut (e.g. enter like in AutoCAD).

Thx

Leader Arrow size and the Architectural tick size are controlled by one and the same value.

It would be nice to get the possibility to adjust them independently from each other ...

It would be nice to have a link possibility directly in QCAD to those files what will be saved with the drawing.
Like the bitmap function without displaying the files in the drawing ...

If I work in QCAD only with Toolbars (and not with the “Cad Tools” there is nowhere a Button to find for “Create Block from selection”.
If I have to create a Block based on a selection I have to work with the Menu or have to activate the Cad Tools.

But, if I look at the Blocklist menu there is a function (+) to add an empty Block. It would be nice to have this button working for both situation - empty Block or depending on a selection to “Create Block from selection”.

Or alternative an additional Button ...

Anyway - in my opinion would that make the “Blocklist” complete.

It would be really cool to have a Note book tool for QCAD!

For example I am often working on a draft and at the same time scribbling notes down on a separate piece of paper relating to the drawing I am working on, could be anything e.g. add a block,add a dimension etc. etc... all sorts of things to remind myself about - all related to a particular drawing.

Of course I could use any number of other programs for this but a simple dedicated tool inside QCAD (could be called the ‘QCAD scribbler ;)) would be much better, especially one that can save the notes to a particular file, then when I open up my drawing again - my notes are there too!

My system: Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz and 8 GB of RAM and NVIDIA GT218 (GeForce 210)

For a normal drawing displaying it in all detail is a good thing and the performance of my quad-core system is more than adequate.

But I discovered (or rather experienced) that when putting a large collection of individual drawings of gears onto one big sheet (960 mm x 600 mm - preparation for laser cutting), the performance was so bad that I had to wait several seconds (>10 sec) for each step in the process of arranging all the parts on the layer.

Request: It would be a big help and performance booster if you could disable the detailed view of each part/layer and only draw a rectangle to visualize the outline of the part.

Please take this in consideration. Attached you find an example of how that could look like. (Actually when pasting a drawing from the clipboard you already do that.)

Would it be possible to add a feature which turns selected text into solid fill hatched polylines?

That would make it possible to migrate the drawing from one computer system to another without having to worry whether the used font is installed on both systems, like when sending a drawing to a manufacturer for laser engraving.

Right now I can do it by hand, letter by letter, and that is a rather labour-intensive task.
