1203dxflibBug ReportLowImages not saved (dxflib)Assigned
0%
Task Description

I am doing a bit of landscaping and using a (big) ortophoto as one of my layers in order to sanity-check on the ground measurements.

The layer contains a point and the image and nothing else.

The image is a 8MB file: “PNG image data, 4200 x 2980, 8-bit/color RGB, non-interlaced” and it is scaled to 210 coordinate units (meter) horizontally in the drawing.

With approx 50% probability the image disappears during Save, as see for instance in this diff of the DXF file:

       EOF

The point in the same layer does not similarly disappear, the bug only seems to affect images.

I have seen this bug from version 3.7.5.0 to git as of yesterday (63e06c778926a803bdfbffdf27b8c24d41511072).

I have not been able to correlate the bug with anything.

Looking closer at the DXF file (attached), there seems to be some residuce of attempts to insert images in protected/invisible layers, so this may be some kind of refcounting issue.

(Any chance of getting FreeBSD into the “Operating System” field ?)

2014QCAD (main)Bug ReportLowFocus on Options Toolbar failsAssigned
0%
Task Description

Scenario: e.g. Tools Move/Copy and Rotate switched to “use without dialog.

Launch within a drawing Move/Copy, use the Keyboard keys CTRL + Space to focus on the Option Bar - the field for Numbers is Highlighted and I can change it. Further navigation with keys on the keyboard depends on remembered option (copy yes/no etc what make a navigation possible or not. It looks like the navigation with the Arrow keys is focused on the canvas and sooner or later the courser will jump to the Command Line or Property editor. Same behavior with the Rotation tool.

1974QCAD (main)Bug ReportVery LowFile > Print Preview: Cannot move paper in new drawingUnconfirmed
0%
Task Description

Yesterday I set up a Windows 64 bit install of QCAD Pro which shows the same bug I have been seeing for a while in the Community linux git repo.

Create a new drawing and then go to “Print preview”. Enable “Move paper postion”, the cursor changes to the hand icon, but the paper position is unable to be moved. Only by saving the drawing, exiting the program, restarting and reopening the drawing, will the “Move paper postion” function correctly.

Affected versions tested:

Windows 64bit installer download, as of yesterday.
Linux 64bit build from git, about 20minutes ago.

For what it’s worth, this bug is not present in this previous git checkout:

1923QCAD (main)Bug ReportVery LowFaulty rendering Polylines with Global/Local Widths and...Assigned

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.

Confirmed by ‘cccplex’ Linux ‘Latest Ubuntu’

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

Task Description

Git head as well as 3.4.5 (trial), both with dxflib 3.3.4.0.

Start up QCAD, (with existing or new configuration, doesn’t seem to matter), “Save as” the completely empty drawing, choose “R15 (dxflib)” on Pro (only this one is available on community), save drawing.

Fire up AutoCAD 2000, try to load the empty drawing just saved.

Result:

DXF read error
Error in APPID Table
DXF read error on line 941.
Invalid or incomplete DXF input -- drawing discarded.

Problem not present when a completely empty drawing saved using Teigha in R15 format is opened (ie. it just results in an empty drawing in AutoCAD 2000). Problem is also not present when saving an existing drawing with Pro (trial) with Teigha and opening it in AutoCAD 2000. Problem does present when trying to open a dxflib-saved drawing in AutoCAD 2000.

Empty drawings created with both dxflib 3.3.4.0 in QCAD Pro 3.4.5 trial and Teigha whatever in QCAD Pro trial 3.4.5 are attached. (Community Git 135fd0 is identical to Pro - same dxflib version.)

The square symbol offered as symbol in DIM label is the only symbol which doesn’t adopt the layer color.

Hi Andrew,

Still working with and on CAM HPGL for the HP7580 pen plotter.

I have added a penplotter test drawing, that might be used for testing en callibrating plotter and pens. You may add it to the Examples-directory.

QCAD has a lot of trouble creating toolpaths and exports. Much too often it shuts itself down, or gets stalled. Why? I am not sure.

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)
