0%
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.)

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:

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 ?)

1214QCAD (main)Bug ReportLowArray of blocks -> Clipboard -> "flip pasted entities" ...Assigned

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.

I wanted to make it so, that SVG units translate 1:1 into CAD units; I use the German localized QCAD and entered 25,4 into the box with the wrong result, i.e. the same as 25; Entering 25.4 got me what I wanted: The question box needs the point and ignores the comma.

1462QCAD (main)Bug ReportLowMac Trackpad zoom gesture not working as expectedAssigned
0%
1 Task Description

Hi,

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.

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.

1916QCAD (main)Bug ReportLowMoving an object in an angled viewport with mouse does ...Assigned
0%
Task Description

To reproduce

1. Select a new view-port in model-space
2. Select the appropriate paper-space
3. When the paper space opens change the angle of the viewport to 90 degrees
4. Place view-port in paper space
5. Select the view-port in paper-space by clicking it
6. Try to move the object itself in the view-port (by clicking the “top” dot) to the right by moving the mouse to the right while holding the left mouse-button.

Actual

The object in the viewport moves down vertically NOT to the right

Expected

The object moves to the right

(It seems mouse movement does not compensate for the rotated angle of the viewport)

Workaround

None, except compensate for the angle in your head and moving the mouse the “wrong” way when correcting the placement of objects in the view-port

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.

Insight is the best way to get better ...
... but the rest is more an odd choice of tools for this kind of task ...

Again, the MISTAKE was by accident, not intended, in a flick of the wrist ...
I didn’t change the trimming method, I simply forgot to ... only once.

The ‘undo’ of my incompetent MISTAKE didn’t returned to how the situation was before I erroneous trimmed with TM.
I was simply undoing my erroneous action.

Documented it in 4 quadrants.
For this, 4 times on purpose, and not as a consistent ‘odd choice’.

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)

Reported is that black is saved as #00004c (dark blue)
Radek (iMac (Retina 5K, 27-inch, 2017), Catalina 10.15.7 (19H114)

My system/installation saves black as #4c000 (dark red)

When using single primary colors these get reduced to #4c, #7f, #99, #cc & #ff.
The threshold for that are #00, #65, #8b, #b2 & #e5
See: DimColorScale (png & dxf)

8 standard CAD colors fail saving correct
Black (something with #4c)
Dark Red, Dark Green, Dark Blue, Dark Cyan, Dark Magenta, Dark Yellow
(#80 turns #7f)
& Gray
(#adadad instead of #a0a0a4)

As with Gray, when mixing the 3 colors it gets rather fuzzy ...
#505050 & #555555 both turn #5b5b5b
&
#464646 turns #4c4226

Task Description

I am getting random crashing on my MacBook M1 chipset while using QCAD Pro. There is nothing in particular that you can do to replicate as the crashing is completely inconsistent. Have had it crash when pressing escape while using measurement tool, but have also had it crash while using the app and selecting a tool.

Included crash report, which has also been sent to Apple.

2284QCAD (main)Bug ReportLowZooming in & out causes grid/snap scale value change in...Assigned
0%
1 Task Description

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.

set value first zoom second zoom next zoom

	point		point		point ...	

0.01 0.1 1.0 10.0 ...
0.02 0.04 0.4 4.0 ...
0.04 0.16 1.6 16.0 ...
0.05 0.25 2.5 25.0 ...

0.0254 0.64516 6.4516 64.516 ...

Why is there a squaring of the original set value? Which then becomes a new zoomed grid/snap value?

2289QCAD (main)Bug ReportLowVertical Line Tool stops accepting inputAssigned
0%
Task Description

When using the vertical line tool, you can enter a length value in the options toolbar, then place the line. If you want to change the length, you just need to enter a new value and the length field will update. However, there seem to be cases where after 10-20 entries, the focus goes off the length field in the options toolbar, requiring the user to bring focus back to continue. I could not seem to duplicate this behavior with the horizontal line tool.

Regarding to forum post:
https://www.qcad.org/rsforum/viewtopic.php?f=33&t=8982&p=35836#p35836

dwg loaded in 3.27.1 frees QCAD (no response) and a Win10 PC. Same drawing loaded in 3.26.0 causes no problems. It looks to me that two hatches (handle 198b6, 198ba) are the culprits.
Drawing saved without those hatches opens without any problem in 3.27.1.
