 2228 QCAD (main)Bug ReportLow Invalid Symbol Table name. Closed
100%
Task Description

During saving file I’m getting information “Invalid Symbol Table name error”. Problem is already known so i tried to follow the instructions given to other users by you. I’ve tried to change spaces to _ symbol in the layers names or deleting polish specific letters but there was no change. I was able to find out that the problem is related only to four layers named: A_ciany... When I delete these layers I’m able to save file without error message. Can you tell me what’s wrong in these layers? I’ve tried to change names of these layers but problem still exists. Best regards.

 2225 QCAD (main)Bug ReportVery Low Filenames containing an ampersand do not render correct ...Closed
100%
Task Description

If a file is opened whose filename contains an ampersand, the filename will be rendered correctly in the application titlebar, but the tab bar and the Window menu will not display the ampersand.

If, however, the ‘alt’ key is pressed, the ampersand will result in an underscore appearing beneath the character immediately following it in the filename string. This applies both to the titlebar and the Window menu.

Interestingly, this can be “exploited” by a user to quickly switch between tabs by pressing ‘alt’ and the character which follows the ampersand simultaneously. Likewise, a user can swap between windows using the Window menu in a similar fashion, by first pressing Alt+W, then Alt and the same key as before.

The expected result is that the ampersand is rendered, the underscore is not rendered, and the ‘alt’ key shortcuts don’t work.

It would appear that this is a simple case of failing to properly escape the ampersand in filenames before passing the filename string to various Qt methods.

When scaling linetypes the scale will change to proper size, after selecting the line again the line reverts to solid (or improper scale). Select the line a third time returns to proper scale.It appears the linetype scale is not functioning properly in 3.26.1.I have attached example files of the issue in both the 3.25.2 pro version (work correctly) and 3.26.1 pro (does not work properly) as well as the linetype file I created.

Andrew,

Break out Manual (B2) on Arc and open Polyline results
seems to depend on the breakpoint picking order.

A segment is broken out when the picking order is in the entity orientation.
The intended behavior.

That differs when the picking order is opposite the entity orientation.
One would expect that the picking order matters when removing
a segment between the picked points.

Example file included

Noticed while merging code to PolyLineBreakSymbol.js
https://github.com/qcad/qcad/blob/master/scripts/Misc/MiscDraw/PolyLineBreakSymbol/PolyLineBreakSymbol.js Line 300-312 orders cut points on distance from start.
Otherwise, the results where inconsistent.

 2201 QCAD (main)Bug ReportLow Purge blocks while editing block in place removes block ...Closed
100%
Task Description

I was editing a block using the “Edit block in-place” and then (because I was exploring QCad a little) tried the “Purge unused blocks” option. I suspect that the purge removed the block I was editing, since when I now click “Save and close”, I get “Original block not found”. Also when I click “Cancel”, I get “Original block reference data not found”.

Recreating an empty block with the same name fixes this, and “Save and close” seems to work as expected again.

This is probably very much a corner case which is not really important, but I wanted to report it just so it is known.

 2196 QCAD (main)Bug ReportLow Leader: Arrow removed on load if arrow only fits first  ...Closed
100%
1 Task Description

Andrew,
This is bugging me for over a year now.
I filed it as a feature request as it is dismissed twice as a possible bug on the forum.
In both cases the advice is to only use Specific Scale 0 for Leaders.
(... and adapt all other dimensions to that)

I am aware that an arrow head has to fit twice on the first leg of a Leader Entity.

The size is set global in the Drawing Preferences under Dimension Settings: ‘Text Height’.
Under Dimension Settings, there is also a global ‘Size scale factor’.
And every dimension entity has a Specific Property called ‘Scale’ that supersedes this global ‘Size scale factor’.

Proof of concept: Dim size 5 and for any regular dimension.
1) Size scale factor 1, Specific Scale 0 » text height & arrow length = 5 units.
2) Size scale factor 2, Specific Scale 0 » text height & arrow length = 10 units.
3) Size scale factor 2, Specific Scale 1 » text height & arrow length = 5 units.
4) Size scale factor 1, Specific Scale 2 » text height & arrow length = 10 units.
5) Size scale factor 10, Specific Scale 0.5 » text height & arrow length = 2.5 units.
6) Size scale factor 99, Specific Scale 0.1 » text height & arrow length = 0.5 units.
→ Obvious is that the ‘Specific Scale’ supersedes the dimensions ‘Size scale factor’.

Those two last Leader arrows (2.5 & 0.5 long) would definitely fit twice on an 8 units long first Leader leg! And they do perfectly while drawing them.

However, the arrow will be reset when the file is saved & loaded.

For case 5 the first leg has to be (2 times 5×10) 100 units or over so an arrow 2.5 long remains on save (=40 times). In the absurd case 6 that would be (2 times 5×99) 990 units or over for an arrow only 0.5 units long (=1980 times).
Verfied and true.

It seems that on save/load:
The Specific Scale is not taken into consideration while evaluating ‘At least twice’.

Apart from that they render fine when first drew.
And reappear when setting the arrow back on again after load.

CVH

Andrew,
While enhancing DrawFromCSV: Forum Link.
I had a peek at the new command line tool: dwg2csv

I would never come up with 115 columns.
That wouldn’t be efficient to generate entities from.
Although this way it is very complete and one could use specific lists to filter.
One downside is that the ‘-list’ switch return is far too vast for the windows command line.



Remarked that:
Only the first alphabetically custom property is listed under:
QCAD:Line & QCAD:Reference (columns 114-115).
And that the last encountered is persistent for all entities that follows.

Maybe this originates from a multiple entity selection ...
... what also retains the last encountered custom properties in the property editor.
Should I add a seperate task for that?



Also had an exception thrown:
Debug: dropped global XDATA (no res buf): “ViewportCenter”.
Discarted that as this very basic test drawing hasn’t even a Viewport.

‘Edit Block In-place (BB)’ is never used in this drawing.
There was never a Block in this file.
I might have switched focus.

Re-installed QCAD a dozen times meanwhile.
Wiped all what remained of QCAD twice.
Cleaned up the windows registry twice.
Lastly left out all kinds of my custom scripts.
Simply a bare install with the msi file.

How to replicate:
- Start QCAD in normal mode
- Load included file
- Set App.Prefs .. Startup .. Restore open files
- Close QCAD
- Start QCAD in debugger mode
(-rescan -enable-script-debugger -always-load-scripts)

Boot fails.
Every successive trial.

When booting in normal mode I see the BB options toolbar blink shortly.

3 Screengrabs in DebuggerModeError.zip in the same topic.
The blink I can’t catch.

I can Boot with no file to retore on open in debugger mode and load the file.
I have several of those files, all were open that day at 2:56 am

Origin:
I like to start my CAM paths at low curvature instead starting at high curvature.
Ellipses may explode with the startpoint at the tip. (file Y2)

Documented in 3.25.2.4, reproducible under 3.25.2.7

File included with 4 LayerStates
- Original Ellipses: Y1
- Exploded to polylines (32 segments): Y2
- Direct after XP, OR performs different on the left top one: Y3
- Faulty solutions by OR: Y4 (= saved state)

The results may differ with the saved explosions.

With the file.
Y1
TA
XP
Relocate startpoint with OR to an existing reference (called ‘End’)

OC to Polyline.
Step through vertices.

No example file provided because these NaN values are not saved to a file.
More pronounced with lines as with arcs.
Less pronounced when recombining after an explosion.
Some methods clear these to value = void.
Some methods clear these to zero (OR).
Can also occur when adding segments to an existing polyline with OC.
