QCAD Professional Win installer 32bit Version: 3.25.2.7 (3.25.2.7) Internet: QCAD.org Build Date: Dec 16 2020 Revision: e06f230 Qt Version: 5.13.2 Architecture: i386 Compiler: Unknown
Documented in 3.25.2.4, reproducible under 3.25.2.7 In the attached file: → Explode the trial cases and locate NaN Widths. → These faulty widths are cleared while saving and reverting. = work around.
Related Post: https://www.qcad.org/rsforum/viewtopic.php?t=7902#p30902 Related Topic: https://www.qcad.org/rsforum/viewtopic.php?t=7901 Related Commit: https://github.com/qcad/qcad/commit/fcd7929bced7ae328029c1aa2ee2aff2745709c6
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)

Task Description
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.

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.

Hi Andrew,
Still working on creating HPGL.PLT toolpaths for the HP7580 pen plotter. QCAD has some trouble creating toolpaths. Too often it shuts itself down, or the PC gets stalled.
Recreating the same error however is possible

Task Description
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: https://qcad.org/bugtracker/index.php?do=details&task_id=695 https://qcad.org/bugtracker/index.php?do=details&task_id=757 https://qcad.org/bugtracker/index.php?do=details&task_id=1157

Task Description
Case:
Select a block array, put it with “Copy with reference” or “Cut with reference” into the clipboard, choose a reference point which isn’t in the center of the array, use the paste tool / with option “flip pasted entities”
If I flip only in horizontal or vertical direction the preview box will double in size and I can’t place the entities precisely regarding to the reference point. If I try to flip in both directions at the same time - you can’t see this effect.

Issues most likely unrelated to OS and installations before 3.25. Related post: https://qcad.org/rsforum/viewtopic.php?&t=7982
Flaws documented in full in attached dxf. The dxf has meaningful Layer States.
4 Columns: - Prior Art - The test cases - Actual results - Results with proposed fix
Tried as many things as I can come up with. Orange: Flaws Red: Errors Green: Good results (or as good as I can get them)
Solution(s) given in attached script explode.js (I am just a simple guy and wouldn’t know how to file a pull request on GitHub ......)
In section: “explode polyline into line and arc segments” group: “if (RPolyline.hasProxy() && polyline.hasWidths()) {....}” All additions, updates & typos are marked with “CVH”, one can textual search for it. Over-documented for sure. Any Eaction is to debug in Windows and is obsolete.
Included PreferencesPage.ui is updated for the all Splines from Text fix Still in consideration: Forcing cubic splines from text to degree 2 ... ... I am rather convinced ...
