2307QCAD/CAMFeature RequestLowTools to create dogbones or corner overcut Assigned
0%
2 Task Description

The inside corners of profile tool paths have rounded inside corners. This occurs because the rounded outside the bit cannot make it all the way into the corner of the feature. Think of tracing the inside wall of a cardboard box with a can of soup. The can makes direct contact with the box walls, but its
round shape is unable to completely fit into the tight corners— there’s always a gap.

In a dog-bone overcut (see the figure in attachment), the inside profile corner is enlarged into a semicircle, allowing the sharp edges of the mating piece to slide through without interference.

When a dog bone is applied to the inside corners, as shown in the second figure in the attachment, the joints fit together nicely!

The following website explains what should be implemented More elegant CNC dogbones

There are two ways to implement this tool. Either you modify the original design (as implemented in Fusion 360) or you can do it at the moment you define the tool path (Estlcam allows you to do this for example). See the feature Corner overcut, on Estlcam website

2354QCAD (main)Feature RequestLowcopy-paste between two QCAD instancesAssigned
0%
2 Task Description

Hello,

I’ve quite often the task to transfer changes from one set of drawings to another (similar) set.
My ideal setup would be to open one set in one window and the other set in another window.
Both windows would be arranged side-by-side (larger monitor).
Changes would be copy-pasted from one set to the other.

From #2352 I’ve learned that there is a command-line option to achieve this.

Unfortunately it’s not possible to copy-paste between these instances.

And yes, it’s important to do this in two windows to see both versions at the same time.
So, tabs are not the answer.

It’s also ok if i could detach a tab from one instance and arrange it aside of the main window (like the property editor).
Than all data transfers would happen inside the same instance.

Best regards,
Klaus

2418QCAD/CAMFeature RequestLowInclude a GroupCustom widget in CAM Toolpath dialogs.Assigned
0%
2 Task Description

Andrew,

Unrelated to OS or QCAD version.

In the postprocessor configuration dialog there is a group box called ‘GroupCustom’.
One can add custom widgets to that, rename it and so on.

Such is not provided in CamProfileToolpathDialog.ui or CamDrillToolpathDialog.ui

It should be possible but we aren’t really able to mix up things with the ‘Message’ QLabel ...
A reserved QGroupBox would do the trick. ;-)

0%
2 Task Description

See:
https://www.qcad.org/rsforum/viewtopic.php?f=31&t=10379

Could you add “plain text paste” as ctrl-shift-V
Why? Because sometimes the clipboard comes in with rich text formatting that’s anti-helpful.
The workaround is to paste into a plain text editor, or the console, then recopy and repaste into qCad.

Either way the ctrl-shift-V shortcut is useful for those trained on other software but:
one could also argue that qCad should NEVER take rich text, and rather only accept the plain text with both CTRL-V and CTRL-SHIFT-V.

— CHV says

Agreed, having encountered it numerous times while documenting with text snippets from elsewhere. :roll:
Even copying Info measurements from the Command Line are Rich Text.

The best place to file a feature request is QCAD Bugtracker:
https://www.ribbonsoft.com/bugtracker/ You may need a different account there or make a new one.

May I remark that Ctrl-Shift-V is already in use for Paste along Entity (PE)
But not when the Text Editor Widget has the focus and dialog Widgets are always modal on a Win OS system. :wink:
Still, I’ll vote for it in any way.:P

2063QCAD (main)Performance IssueLowBad performance while zooming inside layout block with ...Assigned
0%
2 Task Description

Zooming in and out is lagging to the point of unusable. This is happening in a layout block with the cursor pointing inside geometry with hatches. When the cursor is pointing outside the geometry zooming works as expected.
The attached file has a very simplified testcase that shows this problem almost in the same way as a more complex drawing with multiple layers and hatches.

edit: I also attached the more complex drawing because it is a bit unclear to me where the lagging stops. Outside the viewport or outside the paper.

I just noticed the selection box has the same problem!

Nach einigen Überraschungen ....

Es ist möglich Layer in nicht eingefügten oder unsichtbar geschalteten Library Items unbemerkt zu löschen ....

Fallbeispiel 1:
Ich arbeite an einer Zeichnung die u.a. den Layer “Gelbe Linie” benutzt.
Ich füge ein Library Item ein was auch einen Layer “Gelbe Linie” hat.
Ich lösche - aus welchen Gründen auch immer - in der Zeichnung das Library Item weil ich es erst später wieder verwenden will.
In der Blocklist ist es natürlich immer noch verfügbar.
In der Zeichnung lösche ich den Layer “Gelbe Linie” da ich diesen nicht brauche brauche - habe aber natürlich nicht im Kopf welche Layer in meinen Blocks verwendet wurden.
Nach einiger Zeit will ich den Block (den aus der Library) wieder einfügen - dieser ist nun aber unbrauchbar da der Inhalt welcher auf dem Layer “gelbe Linie” war fehlt.
Das Library Item neu aus Library laden um das bereits existierende zu reparieren scheitert da das erste nicht überschrieben werden kann. Ich muss den ersten Block löschen um den neuen benutzen zu können.

Fallbeispiel 2:
Da das selbe (löschen der Layer) auch passieren kann bei unsichtbar geschalteten Blöcken kann es dazu führen das ich zig bereits positionierte Blöcke zerstöre und neu platzieren muss um meine Zeichnung zu reparieren.

Fallbeispiel 3:
Ich sehe in meiner Zeichnung einen Layer “Gelbe Linie”. Weiß nicht was das ist - schalte alle Layer unsichtbar außer “Gelbe Linie”. Klicke auf “Auto Zoom” um zu sehen was den auf “Gelbe Linie” ist. Finde nichts = also leer! Lösche Layer “Gelbe Linie”. Der Layer wurde aber von einem im Moment nicht verwendeten Library Block verwendet. Es gibt keinen Hinweis das ich damit ein Library Item zerstören könnte ....

Lange Rede kurzer Sinn: Wäre es machbar/sinnvoll Layer in Blöcken nur löschen zu können wenn ich mich im Edit Modus der Blöcke befinde?

I am using mac version and I have annoying issue with trackpad.
I use qcad primary with my trackpad and under application preferences (Graphics View/Navigation), my setting is as follows.
Mouse wheel / two finger swipe: Scroll (Trackpad...
Enable pan gesture : unticked (found that enabling this often goes into pan mode when I am just moving my pointer around)
Limit zoom and scroll to prevent overflows : ticked (hoping that this would prevent weird zooming issue. I will describe what I am experiencing later this page)
Reverse mouse wheel direction for zoom :unticked
Mouse wheel zoom factor: 1.02

Things work as expected:

  • panning with two finger swipe
  • and the rest

Issue I am experiencing:

Often, when I am zooming in and out with two finger gestures, the view suddenly sets to some weird state and my drawing goes off the ruler.
The mouse point remains where it is.

Workaround:
Reset viewpoint with autozoom and navigate around.

Expected zoom behaviour:
I expect viewpoint to zoom in / out at where my mouse pointer is or at least the centre of current view point.

1 Task Description

Win7pro 32bit Qcad 3.23.0

Andrew,
The Arc segments of Polylines with Global or any Local Width render faulty where Global Z or any of the arc’s local Z is not zero.

In the attached drawing setting the Global Z of the inner poly to 5,10,...

The setting of Z to not zero affects the radius of the projected arc and not the bulging of the poly.
It also affects the projected widths of the line inversely, but not by changing the widths properties.

Pritty rare combination! True.
Qcad is 2D native! True.

Flatten will resolve this.

It is not a purely visual rendering fault, the poly will explode as such.

Maybe similar flaw as with uneven scaling blocks with arcs.

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)

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.

Where a segment is crossing in another node a non valid node is returned as self-intersection point.

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

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 ... ;-)

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.

Andrew,
For more detailed description please refer to:

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.

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.

1 Task Description

Andrew,

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.

Included below is script code that mimics the functionally of isParallel().

As far as I know isParallel() is nowhere used in the QCAD open source.
Textual only found in RLine.cpp & .h or under: opennurbs, ecmaapi\generated and ecmagenerator\src.

// Example:
// RShape1: RLine(RShape(address: "0xcd70e28"), startPoint: "RVector(969.219858, -171.914894, 0.000000, 1)", endPoint: "RVector(1010.000000, -140.000000, 0.000000, 1)")
// RShape2: RLine(RShape(address: "0x7659770"), startPoint: "RVector(969.219858, -171.914894, 0.000000, 1)", endPoint: "RVector(930.000000, -340.000000, 0.000000, 1)")
