QCAD Bugtracker

This continues a problem that occurred in Qcad 2.2/OpenSuse 11.1:

1. The default paper size is always A4. (minor, but annoying)

2. Here is the serious problem: When I change the paper size to, for example tabloid, in File/Drawing Preferences/Page and in Print/Properties, the print job prints as though it were A4. This occurs unless I first go to Yast or Control Center and (as superuser) change the default page size. Other programs (such as Open Office) don’t require this.

The printer is an HP deskjet 9800, and the problem occurs with either CUPS or hplip printing.

I am using Opensuse 11.3 (I haven’t been able to install successfully opensuse 11.4 on my computer), Qcad
Version:
3.0 Beta 2
Date:
Sep 17 2011
Qt Version:
4.7.3
Edition:
Full Version

The labels of dimensions in PG exporter are moved half text-height. Thats a bit much, and actually, no such movement looks more true to the display of same in QCAD itself.

Starting qcad Beta 3 with command line argument -always-load-scripts will bring up debugger:

Polylines may consist of lines and arcs. The SVG PG exporter writes them as all straight lines. A better mapping than polyline then was path, as is done with arcs now.

A polyline or polygon created from segments always ends up in layer 0, shouldn’t it stay in the same layer as the segments have been?

Switch grid from orthogonal to isometric.

Pendant la réalisation d’un plan le calque 0 s’est verrouillé, impossible de le modifier. En l’enregistrant sous un autre nom le calque 0 est toujours verrouillé.

Hello. My question is: can I run my script under Linux QCAD using Linux command prompt.
Something like this. Print in terminal: “./qcad myscript.qs” And can the script executing without QCAD GUI? I need to make my drawing by printing specific command in linux command prompt without using GUI. So after script end his work I want to have my drawing at destination directory.

Thank you.

Trying to build a hatch area sometimes results in “invalid hatch area”. It would be nice if QCAD could give a hint why / where the problem occurs (where is “line too long” or “not closed”).

If spline boundary has fit points, hatch is loaded with visible inaccuracy.

Calibrate printer X/Y ratio and possibly scale to allow accurate printing even on inaccurate printers.

Chat from  FS#194  singled out, so that can be closed.

Dash patterns in BETA2 are very much out of proportion. BETA2 always PG exports 1:1 and only scales strokes so that in the final rendering they match what a technical drawing would show. As dash patterns depend on stroke, both current stroke and final scale have to be brought in accord.

The patch below also restores the alignment of dashes, so that dashed lines do not end in a gap, at least in most occasions.

Sometimes the text of a dimension (that is in a block - just a suspicion of mine) will not get rotated. I do not know why this.text.getAngle() sometimes returns a wrong value, but there is a simple workaround: always rotate the text with the dimension:

All drawing elements belonging to a layer are not existing anymore after:

1. the layer has been made invisible (unselect the eye symbol of the layer),
2. the drawing has been saved,
3. the drawing has been closed
4. and finally the drawing is reopened.

This behavior has been observed on the following OSes:

• Windows XP SP3
• Ubuntu 11.04

I consider this a bug or at least poor software design.

When I edit the drawing preferences and change the arrow size (under the Dimensions tab), the arrows of my dimensions change as expected, but those of the leaders to not change.

No drawing preference exists to adjust the leaders separately, and scaling a leader does not scale its arrow. I currently must delete my leaders and redraw them completely to change the arrow size. Very inconvenient.

P.S. I’m using QCad 2.0.5.0-Free-1 (Community Edition) and didn’t see that version in your list. Does it have another name?

Dear Andrew,

When I open a dxf file created by QCad2 in QCad3 I see extra reference points to the right when selecting the text. I assume that these reference points have no function. Refer to attached dxf file.

Regards, Rutger

Opening a 4 MB dwg file results in no-response for about five minutes. Opening the same file with DraftSight takes less than five seconds.

It would be nice if one could not only change the icon size of the widget panel but also the icon size of the tool bars.

Scripts that are included through the ECMAScript include function are read with a default constructed QTextStream. UTF-8 should be forced.

If a simple polygon is drawn and a rectangle created within it; the whole then selected and hatch applied; hatching works as expected. The hatching is within the polygon but not within the rectangle.

If the rectangle is made into a block, then hatching does not work at all when the block is included in the selection. If the block is not selected and the polygon is, then all within the polygon is hatched, including the block.

When opening a multi layered file, which has been saved in a previous version with some layers turned off, the following happens:

The file is loaded, all layers are shown as switched on.
The view contains only those layers that were switched on when previously saved.

Repeatable

If the file is loaded with all layers turned on, then saved (all within beta3-2)
then upon reopening:-

The file is loaded and the layers are shown with status as saved.
The view is as expected showing just the ‘on’ layers.

If all the layers are then switched on, the view is unchanged.
