In Linux Mint QCAD offers no ‘Dark’ theme, not sure whether this is a bug or not?

Text - Only simple text is possible. Checked or unchecked option “Simple Text” will not change this. Reboot QCAD after changing shows also no effect.

If the drawing unit is set to ‘feet’ and the dimension format is ‘architectural’ or ‘engineering’, the drawing unit should be implicitly regarded as inch for the purpose of calculating dimension values. Since QCAD uses the drawing unit, the dimension values are off by a factor of 12 when importing drawings from other products.

e.g. Dimension > Horizontal: tolerance inputs should have an icon next to them.

The layerlist shows at any operation all sublayer, even if they were previously hidden!

QCAD3.ini may contain invalid positions for the main application windows, e.g.
[Appearance]
Position.X=-32000
Position.Y=-32000

This leads to an invisible main window after starting QCAD under Windows systems.

Modify > Trim
Choose line as limiting entity
Choose spline as entity to trim
The part of the spline that was clicked should remain but is trimmed instead

If a hatch is selected, then rotated or scaled and this is undone afterwards, the hatch is not selected anymore.

Prints under Windows are offset by the default printer margins.

This is caused by QTBUG-5363, https://bugreports.qt.io/browse/QTBUG-5363

Library items created from existing drawings should have the same unit as the drawing. Currently, the unit of newly created library items is ‘None’.

Spotted a bug with Polyline > Offset (OQ)

On the attached file (png image, link : http://nikel.ovh/~tukuyomi/oq_bug.png ), the white entity is a polyline (1 line, 1 arc, 1 line).
Using Polyline > Offset (OQ) with a big value (1100 in my case), I expect to get the green polyline.
What I have is the red one (also CPU is maxed for some seconds every time I move the mouse.)

Vertical alignment “base” (not supported for MText) is saved as “top”. Using “bottom” to replace “base” would be more appropriate.

After designing one ore more parts you may want to produce them.

Maybe it is a flat part, made out of copper sheet metal. You need several copies of the part and you wonder how you can arrange them on your sheet metal in a clever way, so that you end up with as little waste as possible.

And here software could really speed up the process. It would be a great addition to QCADs CAM abilities if it would be able to produce a cutplan.

Enter the size of the sheet metal (or whatever material), select the part(s), enter number of copies and let QCAD find the best way(s) of arrangement. Additional parameters could be clearance between parts and border margin.

Modify > Lengthen with positive values can shorten the polyline in some cases.

- Import drawing from other CAD application with dimension blocks (*D..)
- Save file with QCAD
- Dimension blocks are exported to drawing file but are empty which can break compatibility with other products

Context menu does not show an entry to “Delete Node” for the first node of a polyline.

Opens an Autocad .dwg file happily (Pro version x64). Allows you to make changes, when you go to save (or save as), you get the “Invalid symbol table name”.

It should figure this out when file is opened and squawk immediately.

Would be extremely useful to get some additional error details that might allow one to diagnose and fix the problem. i.e. “Invalid symbol table name: _” with the name of the offender.

I tried removing unused blocks, no joy.

Hi,

I have a circle and circle is not round.
Unit of drawing is in metres and radius is set to 2.38.
The circle displays as a polygon instead.

Hi,

One day I dragged print toolbar into another monitor. This worked ok when I had multiple monitor in the office.
Then I took my laptop out where there is no external monitor connected.
When I tried to use the QCAD I noticed that the tool bar I had dragged onto another monitor cannot be accessed.
I cannot find a way to attach those floating toolbars...

Expected behaviour:
Floating toolbars should be draggable or provide a button to attach it back to qcad main window.

No workaround to attach floating toolbars.

Hi,

I tried to add a leader and for some reason the arrow does not appear. I found out that this occurs when the line is short. To me, line is sufficiently long enough but somehow QCAD thinks it is too short.

Screenshot shows added leader.

Also when I try to change arrow: no to “yes”, while the dropdown shows yes, I am not able to select it. It just defaults to no.

Workaround:
Draw longer line.

Community 3.15.5.3 (Git 9c49f08b), FreeBSD 10.3, Qt 5.5.1

Start the Dimension Leader tool, click a point. While the rubber line is active, click the “Arrow head” option to toggle it (the effect is seen on the rubber line immediately). Now click it again to toggle. The entire dimension disappears with no appreciable trace left anywhere. The DL tool stays active.

Expected outcome would be for the dimension to just toggle the arrow head style.

This only seems to happen if this double-toggling is done as long as no segment is actually created yet (i.e. once at least one segment is actually set, the repeated toggling works as expected).

... in dependence to the used Units.

I have notice this behavior a couple times before but wasn’t sure what is the trigger for that. Now I figured out one (I’m sure there are more) scenario which shows the effect:

New drawing,
Drawing preferences;
Drawing Units:
Meter,
Meter,
Metric,

Printing Page:
ISO A4

Print Preview:

Auto fit drawing to page - fails to calculate the scale,
Auto fit pages to drawing - fails also ...

Counter test:
same drawing - change Paper Unit to mm,
Reset Paper size to A4 ...

... and it works flawless

Draw > Circle > 2 Tangents and Radius
Choose two arcs or two circles as tangential entities.

I create a drawing using QCAD which is stored using dxflib. For some reasons dxflib must be used. This drawing contains arcs and lines on a separate layer. If the dxf file is processed by an other tool only the arcs are referenced to the specific layer. The lines are referenced to the standard layer 0. It doesn’t matter if I’m using the community edition or the pro edition.

After a some investigations I found that the created dxf file is not correct. I manually corrected the dxf file and it works as it should.

For details please refer to the appended files. Take a look to the ENTITY section and the LINE entities, e.g. line 2370. It is just to swap two entities.

Thanks for support.

On OS X using a trackpad pinch gesture to zoom in / out breaks panning and zooming. When a drawing is opened or created, pan and zoom functions work as expected. As soon as you use a pinch gesture to zoom in/out all zooming and panning operations (toolbar buttons and scroll bars) begin producing erratic behavior. The drawing has to be closed and re-opened to restore proper operation. Other open drawing windows are not affected and work properly unless you pinch gesture zoom in their window.

For all the Linux VI editor geeks, can you disable the <ESC> function in the text edit mode. <ESC> maps to <cancel>. If anything it should map to <ok>. Which creates no harm as it can be later undone. I have accidentally lost edits countless times due to an unbreakable habit.
