I like to start my CAM paths at low curvature instead starting at high curvature.
Ellipses may explode with the startpoint at the tip. (file Y2)

Documented in 3.25.2.4, reproducible under 3.25.2.7

File included with 4 LayerStates
- Original Ellipses: Y1
- Exploded to polylines (32 segments): Y2
- Direct after XP, OR performs different on the left top one: Y3
- Faulty solutions by OR: Y4 (= saved state)

The results may differ with the saved explosions.

With the file.

Draw any open or closed chain of line entities.
Select All.
OC to Polyline.
Step through vertices.

No example file provided because these NaN values are not saved to a file.
More pronounced with lines as with arcs.
Less pronounced when recombining after an explosion.
Some methods clear these to value = void.
Some methods clear these to zero (OR).
Can also occur when adding segments to an existing polyline with OC.

Go to:
Text → Special Characters → Others → “Character Map” pops up.
Adjust Zoom to 100% = display problem (not enough space for the single character.

The square symbol offered as symbol in DIM label is the only symbol which doesn’t adopt the layer color.
If I print a drawing in full color it leads to a black symbol in an otherwise colored dimension.

It is also the only symbol which has a solid filling what is confusing when you work with it in Model_Space ...

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.

The application crashes when I try to change a shortcut in the preferences. And only after resizing the preferences window.
In the attachement are the cli warnings.
I also tried the 3.24.3.9 snapshot with the same result.

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)

In my example I can’t draw a circle with circletangent2 if the defining point is on one of the defining tangents. The tangency is lost when I try to do this.

I attached 4 screenshots: TheExample.png, TryingPoint1.png, TryingPoint2.png and The_Point_Isn’t_On_The_Tangents.png.

Hallo Andrew,

Found a bug in the 3D Simulator execution

Hi Andrew,

Still working on creating HPGL.PLT toolpaths for the HP7580 pen plotter. QCAD has some trouble creating toolpaths. Too often it shuts itself down, or the PC gets stalled.

Recreating the same error however is possible

If a file is opened by clicking on it in an open ZIP archive, autosave will not work.

Linux Mint -64

Autosave function not working, error warning given instead!

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.

Windows
3.0.8
Application preferences > Graphics View > Appearance - Solid grid lines doesn’t change anything?

Windows 7-64
3.0.7
When adding or removing additional viewports,an extra unnecessary window of the viewport is created.

Hallo Andrew,

testing the drill toolpath I used single point markers.

In 3D simulation the tool drills the toolpath AND uses the drill as a mill.

Cam Export and generated G-code is not effected.

Flaws documented in full in attached dxf.
The dxf has meaningful Layer States.

4 Columns:
- Prior Art
- The test cases
- Actual results
- Results with proposed fix

Tried as many things as I can come up with.
Orange: Flaws
Red: Errors
Green: Good results (or as good as I can get them)

Solution(s) given in attached script explode.js
(I am just a simple guy and wouldn’t know how to file a pull request on GitHub ......)

In section: “explode polyline into line and arc segments”
group: “if (RPolyline.hasProxy() && polyline.hasWidths()) {....}”
All additions, updates & typos are marked with “CVH”, one can textual search for it.
Over-documented for sure.
Any Eaction is to debug in Windows and is obsolete.

Included PreferencesPage.ui is updated for the all Splines from Text fix
Still in consideration: Forcing cubic splines from text to degree 2 ...
... I am rather convinced ...

Open QCAD and the application preferences. In the section “General: tool settings " you can resize the columns: Menu, Shortcuts etc.
The problem is that it is not intuitive. The first divider is not selectable and the second moves the first, only backwards.

It would be nice to be able to adjust the zoom factor so that the scale on the screen matches a ruler which I lay on the screen.

Thanks!

Add parameters to the function DL_Dxf::writeVPort.
This way users will be able to specify the desired viewport.

Is the github the official repository? Are pull requests sent there accepted?

QGroupBox widgets with <property name=”checkable”> are not saved in Qcad3.conf

1. The Scrollbars for each window in the Viewports has the same size like the normal used scrollbars for windows. If you are working on a normal size Monitor it “steals” a lot of “working space”. Is there any possibility to make the scrollbars smaller or just a line to separate the windows so that I have to navigate with Keyboard and mouse?

2. I thing the Viewports and the View List belongs together - is it possible to get a button in the “View List / Tool Bar” to choose a Viewport style instead of “walking” the long way over the “Drawing preferences” Menu?

When working with multiple Viewports with different scale it could be very useful to have extra properties controlling how dimensions are rendered in the viewport:

1)
E.g an extra “Dimension Scale” under “Scale” in the Viewport selection’s ‘Specific Properties’ section, could allow having the same size when printed.
This Dimension Scale would be multiplied on top of the Scale value, but only for Dimensions rendering.

2)
Toggle button for hiding any dimensions in the Viewport. Maybe this should be controlled by being able to specify a Layer that should be hidden in this Viewport only, then I could select my Dimensions layer here.

The Viewport properties:

Add alpha property to filter for hatches.

Save layer state (visibility) with each added view object (optional?).

It would be a nice feature to be able to define your own toolbar.

See: http://www.qcad.org/rsforum/viewtopic.php?f=32&t=2393

To have the option to set your own ‘user defined’ line weight.

UCS support.

Hi,
this is a usability feature request:

If you want to move an object relatively to any point (e.g. by entering @x;y in commandline) it does’nt make sense to enter a starting reference point. Of course this is possible by clicking to any location on the screen. But it’s difficult to change between mouse and keyboard so often.

It should be possible to enter a “don’t care” or “any” reference point by pressing a keyboard shortcut (e.g. enter like in AutoCAD).

Thx

If there is no selection the Properties Editor could be used to predefine the properties of to be drawn elements.

E.g. use Millimeters for construction while dimensions are displayed in Meters.

Feature request - to have an option to underline text.

My system: Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz and 8 GB of RAM and NVIDIA GT218 (GeForce 210)

For a normal drawing displaying it in all detail is a good thing and the performance of my quad-core system is more than adequate.

But I discovered (or rather experienced) that when putting a large collection of individual drawings of gears onto one big sheet (960 mm x 600 mm - preparation for laser cutting), the performance was so bad that I had to wait several seconds (>10 sec) for each step in the process of arranging all the parts on the layer.

Request: It would be a big help and performance booster if you could disable the detailed view of each part/layer and only draw a rectangle to visualize the outline of the part.

Please take this in consideration. Attached you find an example of how that could look like. (Actually when pasting a drawing from the clipboard you already do that.)

Would it be possible to add a feature which turns selected text into solid fill hatched polylines?

That would make it possible to migrate the drawing from one computer system to another without having to worry whether the used font is installed on both systems, like when sending a drawing to a manufacturer for laser engraving.

Right now I can do it by hand, letter by letter, and that is a rather labour-intensive task.

This is a trim method I am missing in Qcad.

20 years ago it existed in CadKey.
You had a bunch of lines or segments.
You defined a (new) line or segment as cutter.
‘Trim All’.
You pointed at the side of the cutter entity to trim all intersecting at that side.

Pritty the same as in this topic:
https://qcad.org/rsforum/viewtopic.php?t=5221

Only in rare cases I can use Husky’s workaround as pro.
It all depends on what else is in the clipping rectangle that is needed to trim all intended.
If of no use all single crossing entities have to be chosen one by one.

CVH

Hi Andrew

A request for adding some fields to the toolpath

See also:
https://www.qcad.org/rsforum/viewtopic.php?f=83&t=4923

Eine oft Hilfreiche Zeit/Klick sparende Erweiterung wäre eine “Total” Option bei dem “Lengthen” Tool.

Aktuell ist es mit dieser Funktion möglich ein Element zu verlängern oder zu verkürzen um den Amount X. Der Referenzpunkt (von welchem Ende) kann bestimmt werden.

Die Erweiterung die ich mir wünschen würde wäre auch ein “Total” um ein Element auf eine bestimmte Länge zu bringen ohne einen Taschenrechner benutzen zu müssen. Referenz (welches Ende oder Mitte) sollte (muss) dafür wählbar sein.

Die Funktion “Property editor” stellt bereits über die Geometry Eigenschaften die Möglichkeit zur Verfügung einen “Total” Wert zu manipulieren. Leider bin ich aber hierbei nicht in der Lage zu bestimmen welcher Element Referenzpunkt dafür benutzt werden soll. Könnte ich die Referenz wählen (welches Ende oder Mitte) wäre auch dies dann durchaus akzeptabel

Because modifying hatches have lag issues I’d like to propose a toggle that turns of the redrawing/rendering of the hatch. Especially while modifying the hatch.

The hatches always have a boundary that can be worked with right? So when we move or stretch the hatch we can still see the boundary and its handles to perform all the actions.

This could be a new view mode that turns of the view of the interior/pattern of the hatch but leave the boundary of the hatch.
Or the draft mode can be extended to include simplified hatches while modifying.

Also see the discussion

To re-introduce Tile and Cascade window options like as before in QCAD 2.2.2.

It might be useful for some to have the option to turn on/off ' auto’ dimension tracking option.

See related topic:
http://www.qcad.org/rsforum/viewtopic.php?f=2&p=6893#p6893

To add the option to ‘print only’ selected area in a drawing.

Add support for automatic text line wrapping for multiline text entities.

The Omega button to insert special characters is only available in rich text mode.
Make it available in simple text mode as well.

I think it’s a useful adition and makes it easy to select objects that are overlapped. I know there is a selection filter, but sometimes this is faster and/or all the objects share the same type and such things.

If I remember correctly, Inkscape has this behaviour.

Thanks.
