QCAD Bugtracker

When I zoom, the text disappears in certain zoom levels after updating to the latest version.

I would like to request a new kind of snap: a “Restricted Intersection” snap that appears at the point where an entity would intersect with a line drawn from Relative Zero that fulfills the current EL criteria. “Restricted Intersection” snaps would be similar to other Relative Zero-based snaps (like “Perpendicular” and “Tangential”), but would predict the point of the snap from the EL constraints instead of the characteristics of the entity being snapped to. Naturally a value of 0 for angle or length would result in that constraint being ignored.

Additional operational flexibility could be achieved by allowing the snap to exist regardless of whether EL is actually in use. To be useful this would probably require determining snap locations based on angle OR length as opposed to angle AND length.

Implementing this new snap would allow, for example, for easily drawing a line of unknown (but determinable) length at a specified angle between a given point and a given entity (see discussion here), with the “Restricted Intersection” snap ensuring that the endpoint of the new line forms an intersection with the entity in question. Currently the same goal can be achieved a couple of different ways, but they all involve at least two separate steps.

This is either a bug or a feature request, depending on perspective; my apologies if I’ve picked the wrong one. Additional discussion can be found here.

Steps to reproduce:
1. Create an entity
2. Run “Create Library Item” [BT]
3. Select Reference Point

Expected outcome:
“Save As” dialogue opens in the directory that the previous library item was saved in

Actual outcome:
“Save As” dialogue opens in ( RSettings.getLaunchPath() + “/libraries” )

Additional Context:
The reason I’ve categorized this as a bug is because, relative to the behaviour of the main “Save As” dialogue (which does remember the last directory used) the behaviour of the “Create Library Item” “Save As” dialogue is unexpected.

Software versions:
QCAD 3.25.2 Pro
Windows 10 Pro

Text dialog (QTextEdit) strips tabs in toHtml.
If tabs can be retained, text entities could support tabs.

Looks like error, but may be that’s feature request.

CAD software uses typical navigation behavior as:
Wheel = Zoom; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right.

Any other software like browsers, office software (openoffice writer, ms excel and so on), 2d paint software like GIMP (Photoshop and so on) uses other behavior:
Wheel = Scroll up/down; Ctrl+Wheel = Zoom; Shift+Wheel = Scroll left/right.

Users, that intensively use CAD and other software simultaneously prefer to make same behavior in their applications switching CAD scroll to plain mouse wheel.

QCAD’s “Application Preferences”: “Graphics View: Navigation”: “Mouse wheel/ two finger swipe”: “Scroll” allow user to assign scroll up/down to wheel mouse instead of Zoom. But there is mistake Ctrl+Wheel didn’t change to Zoom. Ctrl+Wheel continues to scroll up/down, as the wheel.
Wheel = Scroll up/down; Ctrl+Wheel = Scroll up/down; Shift+Wheel = Scroll left/right. No zoom!

Draw manipulation at this mode like a hell: you need to use wheel in conjunction with Ctrl/Shift to point draw in desired position, than move your hand to +(-) for make desired zoom.

The conditional clause of this sentence is ‘the odd choice’.
Blaming this on incompetence.
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)

Not related to OS, nor version.

The method Polyline from Segments (OC) can be configured for tolerance and simplification in the Options Toolbar.
The method Polyline from Selection (OG) has no UI or none showing.

OG retrieves a tolerance from QCAD.ini, what is initially not set:

    var tolerance = RSettings.getDoubleValue("PolylineFromSelection/Tolerance", 0.001);

The tolerance will be default = 0.001 similar as the default in AppPrefs.
The tolerance setting is included in QCAD.ini after changing the AppPrefs entry.

OG calls PolylineFromSelection.autoJoinSegments with this tolerance:

    var counter = PolylineFromSelection.autoJoinSegments(di, tolerance, this);

PolylineFromSelection.autoJoinSegments calls PolylineFromSegments.createPolylineShape
with simplification hard coded to true. (last parameter)

    // create polyline from line, arc, spline or open polyline entity:
    var polyline = PolylineFromSegments.createPolylineShape(
                    entity, doc, vTolerance, op, undefined,
                    traversed, callBacks, undefined, true);

I would like to see the simplification optional and default = true.

When placing a hole at x0 y0 there is no G00 x0 y0 in the exported G-Code.
So the first cut was made at the current position of the tool, not at x0 y0!

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

Select the previously selected entities.

The option for vertically and diagonally stacked fractions would be helpful for both the text creation tool and as the output of dimensions.

An option for unidirectional dimensions, in addition to the default aligned dimensions.

Add functions to the Reorder tool, similar to the functions of the counter tool, undo last step and start at any number, allowing corrections and restarting the tool part way through.

See the discussions at https://qcad.org/rsforum/viewtopic.php?f=32&t=8170

The “Define annge using mouse cursor” of the Rotate tool would be useful in the Move and Rotate Tool

When saving a view, it would be great if the view also saved which block (model space, layout block, or any other block) that was active at the time the view was saved and when the view is later re-activated, the corresponding block would re-activate.

Hi Andrew,

Creating G-code for cnc-laser, the laser-tool can not be correctly set at all.

Attached a laser tool proposal

Add SPx; with x being pen number from 1-8.

TODO:
- Which color corresponds to which pen number?
- What if there are more than 8 colors in a DXF files?

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.

Hi Andrew

QCAD/CAM misses a hpgl.plt import. If gerber and G-code can, so should plt.

Hi Andrew

A request for adding some fields to the toolpath

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

Hallo Andrew,

I am still busy on the never ending G-code story. Doing so I wrote a small Post Processor Tutorial for all those nerds who wants to write their own. If you like it you might add it to QCAD. However, since English is not my native tongue I suggest checking it would be wise.

Meanwhile I have downloaded the source code, and could not find the CAM’s Drill-path-script. I am now using a negative Drill Cut Depth to set a Laser Dwell time, were as a field “Dwell Time (in seconds)” in the Drill-path would be more appropiate. Is this script open source available or is it part of ‘closed part’ of QCAD?

Hallo Andrew,

Still busy on the never ending G-code story. Urgently needed the very common Traverse Toolpath.

Example added as pdf.

Greetings

Hallo Andrew,

Still busy on the never ending G-code story. Urgently needed the very handy G-code Block Toolpath. This ‘toolpath’ also solves a lot of “editing requests”.

Hallo Andrew

It would be more than conveniant, defining the drilling locations of the drill toolpath, by selecting a circle’s center point.

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.

Add a program description to the CAM configuration dialog and export to postprocessors as variable.

Hallo Andrew,

I have revised the PWM Post Processor to Revision D.

Hallo Andrew,

Found a bug in the 3D Simulator execution

With a Mac (and no external mouse) there’s no middle button so it’s not possible to pan the 3D view (that’s what they tell me in the forum). It would be useful if one could use command-drag or control-drag to pan around the 3D view.

Andrew,
While enhancing DrawFromCSV: Forum Link.
I had a peek at the new command line tool: dwg2csv

I would never come up with 115 columns.
That wouldn’t be efficient to generate entities from.
Although this way it is very complete and one could use specific lists to filter.
One downside is that the ‘-list’ switch return is far too vast for the windows command line.

Remarked that:
Only the first alphabetically custom property is listed under:
QCAD:Line & QCAD:Reference (columns 114-115).
And that the last encountered is persistent for all entities that follows.

Maybe this originates from a multiple entity selection ...
... what also retains the last encountered custom properties in the property editor.
Should I add a seperate task for that?

Also had an exception thrown:
Debug: dropped global XDATA (no res buf): “ViewportCenter”.
Discarted that as this very basic test drawing hasn’t even a Viewport.

Regards,
CVH

Added: Snippet from DrawFromCSV code (merely a test case)

CSVcomma/semicolon
Offset;50;50
Point;39,789355;-0,815325;+[Custom;Reference:101];
Point;38,49526;4,014304;+[Custom;Reference:102;Line:56]

The two points, and only those two points, are casted with custom properties
QCAD|Reference|101
QCAD|Reference|102 & QCAD|Line|56

Added: The dxf file
Added: The csv file (change to the comma/semicolon style)

It would be nice if QCAD spit some kind of warning message when trying to render a layer with a name that doesn’t exist (and perhaps render nothing), rather than silently rendering an empty image. :D

See https://qcad.org/rsforum/viewtopic.php?f=33&t=6453

The 3dConnexion Space Navigator would be wonderful as a pan and zoom control. I find it extremely useful in SketchUp and when I switch from that to QCAD am always disappointed to find it doesn’t work.

3dconnexion DOT com/buy/shop.html?3dxcp=GA_GA_search_google_US_Brand

While full support for the buttons and such would be nice, just the ability to map the axis to pan and zoom would be wonderful.

Add configuarable format options in application preferences for saving blocks to library to either dxf or dwg.

QCad 3.19.2 Professional, 64bit, Liux Mint

Case:
1. Open some saved drawing with viewport entities on layout block (paper space). Print Preview mode is “On” automatically.
2. After “File-Revert” drawing is reopened on layout block (paper space), but now Print Previw mode is “Off” .

For example can try on “flange.dxf”

Drawing converted from inch to mm - undo leads to wrong dim label position. I can fix that with “Reset Label position” but it would be nice if QCAD could to that in first place.

I know this was reported and fixed before ...

https://www.qcad.org/bugtracker/index.php?do=details&task_id=843

... but it looks like we have the issue now back with some kind of variation.

If I use the test drawing which I posted in 2013 ( FS#843 ) it works still as expected after it was fixed.

If I create a new block it won’t work in a new drawing nor in the old test drawing - no chance to snap to the Block Reference.

Edit: New Test drawing:
