QCAD Professional
Win installer 32 bit
Version: 3.25.2.4 (3.25.2.4)

Qt Version: 5.13.2
Architecture: i386
Compiler: Unknown
Investigating block functionality deeper ...
Even in a crippled file:
https://www.ribbonsoft.com/bugtracker/i ... sk_id=2021
(To be clear upfront: This is NOT my file, NOT made by me, the methods are NOT by my preference.
I have NO clue what application created this. I only know that QCAD supports it)
Took a snippet of that file:
On open this renders fine.
The autoZoom is rather expanded since the Block Reference is at (-5677,8123) but the entities are rather at (~41000,~31000)
I find no way in 'box-selecting' these entities with the mouse while holding the button ...
... one can not select the block at its reference point ...
... but one can simply select the block with a left click near the displayed entities ...
Question 1: Can anyone confirm this?
TA (Selected = 'Block 1')
XP (Explode 'Block 1')
ZA >> Looks good
TA (Selected = Block 'KOD')
XP (Explode Block 'KOD')
ZA
>> Circle segments are turned huge:
This is by the combination of bulges on polylines with widths and non-zero Z values.
2019, 3.23.0: https://qcad.org/bugtracker/index.php?d ... sk_id=1923
>> All entities have Z = 6728.2997
Question 2: Can anyone confirm this in 3.25?
QCAD = 2D Although it renders the original file perfectly as far as I can tell.
Slow, that for sure. Try to edit the block 'KOD' there.
It is obvious that this simple block slows QCAD down more then others.
(*EDIT appearing 84 times in a file saved as dxf)
Flatten the snippet to 2D:
Same procedure ...
All turns out fine but the text is still at Z = 6728.2997
Question 3: Can anyone confirm that only the text has a non-zero Z value?
Additional question 4 (Sure, off Topic):
Explain the circle segment by a polyline with a very specific width=2R ???

IMHO it should look like:
Re: Issues with blocks ... and so
I can boxselect and select by clicking on the entities.
The circle polyline only fills part of the quartercircle.
I don't have a Z value. Were is this property visible?CVH wrote: ↑Sun Dec 13, 2020 6:42 am>> Circle segments are turned huge:

The text has dissapeared.
My pline segments are huge indeed.
My polyline has a width of R. Apparently to fill the circle by using the linewidth.

Re: Issues with blocks ... and so
Thanks, cccplex
Z values can be made visible with AppPrefs Ctrl+, or Menu .. Edit .. Application Preferences
.. Widgets .. Property Editor .. Display Z coordinates
R .. 2R .. Are you meaning the R of the circle?
I mean R of the polyline arc. (I was't specific enough, my bad )
A box around the entities doesn't select anything here.
Nor where the reference would reside.
Yet another thing to figure out ...
You are a PRO user since 2017 ... I am supposing ...
The font is 'simplxtw' ... Don't have that installed either, it seems QCAD falls back on Arial, 100% match.
I have text rendering as text set in AppPrefs .. Graphics View

Try altering the Global Width in block 'KOD' from 4.5 ... 5 in 0.1 steps.
This confirmes it should look like the picture I posted.
With Width = Rarc QCAD swaps from sector to segment.
Thanks for confirming some.

- In the block 'KOD'
bulge = tan(a/4) = 0.414214.. = sqrt(2)-1 (where 'a' is the enclosed angle)
a = 4*atan(sqrt(2)-1) = 90°>> 1/4 circle
Rarc = dist/2/sin(a/2) = 3.394113../2/sin(90/2) = ~2.4 (where 'dist' is the distance from begin- to end-point)
width = 4.8 = 2Rarc = Rcircle

Selecting by clicking on the entities wasn't the problem.
A box around the entities doesn't select anything here.
Nor where the reference would reside.
Bummer.

Called a circle (circular) segment, with those numbers I/we expect a circle sector.

Re: Issues with blocks ... and so
Good to know. So yeah. The Z-values match up here.
Ah, ok. Doesn't matter. The pline arc has half the radius as the outer circle. So it has a width of 2R to fill exactly a quarter of the circle. Too bad it doesn't work in my load. If i fiddle a bit with the width it does work.
Aha, but how can it take the segment of the outer circle? More testing shows me that width flips to a segment when the arc is smaller then half of a circle. Must be some unwanted behaviour.
It works for me if I box around the entities and the reference (in one box).
So after exploding the segments are this huge And setting the Z-values to zero fixes this.

Re: Issues with blocks ... and so
Thanks,
It seems that all is confirmed.
I see that the text isn't missing...
Now the hard part: Entering a Bugreport
Suggestions and features works, bug always return 'WRONG TOKEN'.
I'll try that from another (newer) PC, with another (newer) browser.
Or as another user ...

Re: Issues with blocks ... and so
Was able to file a bug report on the PolyArc=2R:
https://www.ribbonsoft.com/bugtracker/i ... sk_id=2155
The rest needs a little more documentation ...

Re: Issues with blocks ... and so
Attributes are disappearing after synchronization? Is this user error?
I define a block, and 4 attributes
Insert the block into the main drawing, everything is fine.
Then edit attribute property in the block definition - text size
Return to main drawing - Synchronize - and 3 out of the 4 attributes disappear from the inserted block?
