QCAD Bugtracker

Case: My last “Print preview” setting was “Multiple Pages” = 4
QCAD will remember this setting until I change it.

If I then - maybe days later - start a “Print current view” out of my drawing then QCAD will show me the current view on ONE page. Exactly what I expected. If I start the print QCAD will print on FOUR pages regarding to the last “Print preview” setting. Not what I was looking for ....

Now knowing what will happen I launch “Print current view”, see my current view on ONE page, launch the “Drawing preferences”, see that FOUR is the number for pages, doesn’t change anything and cancel the dialog. NOW I can see that FOUR pages are used for the current view print.

That is confusing and it would be nice to have somehow more control over this behavior.

1. Create polyline with global width (e.g. 10)
2. Scale polyline by factors X=-1, Y=1
3. Polyline loses width

In the attached drawing, the origin is at the lower left, but $EXTMAX 10 = 0, 20 = .66473 and $EXTMIN = 10 = 3.2, 20 = 0

The X value for $EXTMAX should be 3.2
The X value for #EXTMIN should be 0

the following is an excerpt from the file
$EXTMIN
10
3.2
20
0.664730029289

Please can you provided a worked example for scripting (I can’t find anything similar in the Help/Book)?

I have a 2D drawing that has a segmented circle that is divided into 12/16/20 segments etc.

I want to show this in a side 2D view e.g. there are 6/8/10 segments visible to fill in a rectangle.

I can manually calculate the distance to draw vertical “fill” lines by calculating the angle of the end of each segment. With the option to rotate the position of the lines by half/third of a segment.

A simple example with only 2 segments visible, it’s 0, 50% and 100%.
With 4 segments, it’s tan(22.5), tan(45), -tan(45) and 90 degrees that’s approximately 41%, 50%, 59% and 100%.

So the task, is to receive the coordinates of the area e.g. a rectangle, divide the rectangle into unequal smaller rectangles.

I imagine that a 3D program can do this, but I want to do something similar. Perhaps this is more easily applied - I’m new to CAD and QCAD.

My best guess is this was introduced sometime during last week or thereabouts (i.e. before that, Git HEAD used to work fine).

Scenario:

launch BE / Edit contents of selected block,
Pencil symbol shows that this block is now in edit mode,
launch Rename Block / rename it, confirm with ok, dialog closes,
renaming doesn’t works, pencil symbol is still on that block,
try to launch rename block again - doesn’t work anymore,
return to main drawing,
if I then select this block it will show the new name in the Property editor but not in the block list,
if I try to open this block within the block list again it doesn’t works,
if I open this block within a double-click in my drawing it will open but the pencil isn’t shown.

Hello

So, I think .. that when the dark scheme has been chosen
the eye color for the active layers should be white
(similar to the list of blocks).

Best regards
Jacek

Hello

I noticed that
when the dark scheme has been chosen
the shortcut for any toolbar tool, shown inside tool tooltip
has color similar to the tooltip background
which makes it invisible.

When doing the selection shown in attached image, only horizontal line gets selected.

This only happen in some drawings. When starting a new drawing all selects as expected but when increasing complexity some lines can’t be selected using crossing selection.

If you copy/paste to new file it’s still not working, nor in other computer.

Create new drawing.
Add new layer (Layer 1)
Layer 0 still selected (highlighted) but new entities drawn on Layer 1

Very best

Block array column and row spacing not scaled in unit conversion.

If the print preview is opened automatically using File > PDF Export, the print preview does not open correctly or is unclosable (script exception).

using the trim (RM) command
the drawing has a circle with a line going through it. I want to trim the line ends to the circle with the remaining lines inside the circle.
select the circle as limiting entity.
command line says Choose entity to trim. click the line on the right side of center, the excess line on the right is properly trimmed.
command line says Choose entity to trim. Click the remaining line inside the circle on the left side of center. nothing happens.

if I exit the trim command and re-enter, now I can trim the left side of the line

Layers issue has returned. Add new layer and the new layer, even though active, is not highlighted although the pencil icon shows. And in some cases no layers are highlighted after the new layer is added or the wrong layer is highlighted after adding new layer. 3.22.09

A margin of 0px can still lead to a margin if width is much larger than height or vice versa.

Create text with formatting:

\fArial|b0|i1|c0|p0;R\fArial|b0|i0|c0|p0;\S^2;

i.e. Capital, italic R with subscript 2 (not italic).

Edit text.

Formatting changed to (invalid):

\fArial|b0|i1|c0|p0;R\S^\fArial|b0|i0|c0|p0;2;

Now I try the third time to post this .... .... deleted by “wrong token”???????
However ...

Regarding to the online tutorial:

quote:
Opening a CXF Font for Editing

To load an existing CXF font file in QCAD to view and edit its glyphs, simply use the menu File > Open and choose the format filter “CXF Font Files (*.cxf)”. Then choose the font file you want to open. The fonts that come with QCAD are stored in directory “fonts” of your QCAD installation.

quote end

Editing the cxf font in the original QCAD font folder will lead to a error message triggered by the Autosave function:

File access error: “C:/Program Files/qcad-3.22.1-pro-win64/fonts\~~Husky_test_font.dxf”. Access is denied.
[15:34:58] Autosave failed: C:\Program Files\qcad-3.22.1-pro-win64\fonts\~Husky_test_font.dxf

Note: Windows will not save anything in a system folder and the process is terminated by windows.

Solution: Move the cxf font for editing from the QCAD folder to a unprotected folder like Documents/drawings.
After editing is done move it back to the QCAD font folder.

I’m not able to import any dxf or dwg.

I guess I’ve discovered a bug:

Text elements align the same no matter if “base” or “bottom” alignment is chosen. The text is “shifting” (in both cases) when the characteristic “contains glyphs that cross the base line” is changed. Same shifting also occurs with text aligned “top” with having no glyphs reaching the top-line.
I assume this isn’t the intended behaviour ...

For demonstration I attached a file where I’ve put lines (to align with) and three sample texts “as” (only “center”-glyphs), “aps” (glyph crossing base-line) and “this” (glyphs reaching top-line), each aligned with all vertical alignment-options (1-top, 2-midlle , 3-base , 4-bottom).

Hope fixing this dosen’t take too much effort.
Regards,
Volker

The problem is related to PDSIZE being set to 0 which means “5% of drawing area height”.

Layer states in DXF/DWG files may contain NULL layers (likely deleted layers). Import fails in these cases.

QCAD community edition.

I use this program to generate CAM data. Whenever I save a the same text in different layers - one of the layers saved has broken lines. I have to spend hours extending and trimming each segment to reattach them.

Duplicate problem:

New file
Add some text
Explode into lines
Add layer
Add same text to same location on new layer
Explode into lines
Save file

Full 360 degrees Arcs don’t convert correct to polylines with the methods OG and OC.
Both methods create a zero-length open type Polyline and remove the full Arc.
OG creates a Poly with 2 vertexes at the startpoint (= endpoint) and OC one with 0 (zero!) vertexes.
The firts one is selectable, the second one only with ‘Select All’//TA because there are no references.

The OL method with the same start and endpoint doens’t affect the full arc.
Neither a poly is created nor an error is generated that the method failed.

Typical the bulge of the OG method is (-)16331239353195370, the OC method has no references.
The math to calculate the bulge should result in a division by zero or an illegal function as tan(π/2).
Therefore a polyline can’t contain a 360 degrees arc by standard means.

From the OC method is known that it simplify coradial arc strings to a single arc.
This should not result in 360 degrees arcs what would result in zero-length segments.
(With CAM fuzzy things may happen at such positions)

Simplifying coradial arcs strings that would create a 360 degrees arc should result in no less then two coradial Arcs.
The OG method will then creates a open Poly with 3 vertexes, OC a closed one with 2 vertexes.

Found while fiddling around with editing CXF fonts.
CXF uses full Arcs, two half arcs and even polylines with coradial segments that forms circles are supported,
the OC closed polyline with 2 vertexes is recoded as two 180 degree Arcs (90-270&270-90).

Regression caused by fix to  FS#1899 .

Please take a look at 1898 again. There is a problem.

Hallo Andrew,

Testing the drill toolpath I find it hard to select the correct tool by a small bug

Hallo Andrew

If CAM layer invisible do not 3D Simulate and do not write G-code.

Set up a spline with control points let’s say of the order 3.
Clone it 3 times with some offset in x&y.
Edit the degree property and set 1ste to 1, 2nd to 2, aso
Draw select partially from right to left.
Those of the order 1 and 4 aren’t selected.

Draw an arc.
Select the arc.
In Property Editor:
Set start angle to 135
Set end angle to 135

SweepAngle = */-360

edit the end angle and add “+360”, hit enter

SweepAngle = 0

An arc with zero sweep is a point.
A point is not an arc.
With the same start and end parameter an arc should have a sweep of +/-360.
As for entries by points or by angles.
