Offsetting 32 polys from ellipses fails.
Offsetting 16 polys can be completed with 2 selections for outer and 2 for inner.

For some reason the offset function halts premature.

So far, layer status has only been implemented very rudimentarily.
I wish something like a dialog box in which you can choose for each layer status, which layers belong to it and which not.

It may be useful to insert the “image cropping” function both in top / bottom - right / left mode, and with polyline

“Paste” has already the options: To current layer, Overwrite layers, Overwrite blocks.

Would be a nice time saver to have the same options for “Paste along Entity” too.

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.

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.

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.

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)

(#adadad instead of #a0a0a4)

As with Gray, when mixing the 3 colors it gets rather fuzzy ...

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.

implement

Find way to support custom line weights for SVG export. See also forum thread: http://www.ribbonsoft.com/rsforum/viewtopic.php?t=1594

command line arguments: allow class name after -exec

It would be nice if one could select multiple blocks in the block list at once (holding ctrl or ctrl+shift). Main purpose would be to delete them if they are not needed anymore. If possible, the same applies to layers.

I think it would be nice to have more flexibility for Prefix etc. option (not only the drop down with a given choice) and a remember function for all those fields like postfix and tolerance.

Why Remember Function:
If I use a postfix like <>” in the postfix field I’m only able to use it for this particular dimension type at this time. If I change the type (from Horizontal to vertical or what ever) I have always to repeat my postfix. The same with tolerances.

Blocks: moving complex blocks with drag and drop should show bounding box as preview

A missing feature in my work are logical operations (combine, intersect, ..) for polylines

Example:
Draw some elements, select them, say combine. The result will be the outline of all elements.

There is an issue importing from Autocad:
lines and quotes (both arrows and text) appear too much big (see attachment).
I can fix quotes modifying dimensions in “current drawing preferences”, but lines are still too thick.
Autocad’s dxf are opened with right line thickness but wrong quotes.
Furthermore, Autocad opens Qcad’s dxf files showing wrong quotes.

Select lines, arcs, ... and convert them to points along the lines, arcs, ... with a fixed distance.

Wähle ich für die Punktbestimmung “Intersection manual” muss ich dies für jeden Punkt immer wieder neu anwählen. Schlecht

Apparently this was possible in QCAD 2 due to the default behavior of Qt.

The selection tool is not accessible:

Click on Selection Tool icon - left panel:

Left panel then shows line tool options.

Click “back” button at top of left panel:

Left panel then shows selection options.

Click an option icon:

Left panel then shows line tool options again.

Hi,

in QCAD3 RC2 points were printed as crosses, in QCAD3 RC4 they are printed as (very little) points. I think this isn’t a bug but a feature.

It would be nice if one could change this behaviour / select the symbol of points.

This is a double post of http://www.ribbonsoft.com/rsforum/viewtopic.php?p=5870#5870 as suggested there.

Ziehe ich mit der Maus eine normale Auswahlbox kann ich Elemente markieren.
Möchte ich einzelne Bereiche wieder herausnehmen muss ich alle Elemente einzeln anklicken (mit gedrückter Shift Taste).
Ich kann zwar dies komfortabler gestalten mit der Select → (De -) Select Contour Funktion welche aber erst über das Menue aufgerufen werden muss.

So wie ich einzelne Elemente mit der Maus auswählen und mit der Shift-Maus Funktion deselektieren kann wäre es schön wenn die Shift Taste auch bei Auswahlbereichen direkt zum deselektieren eingesetzt werden könnte.

As an old professional “documentation writer and user inteface designer” but IMHO, I’m not convinced that the “Application preferences” are correctly organised for ease of understanding and using them.
These settings are organised in 2 levels. Some of the first levels have their own settings (e.g. “Graphics view”) while most others don’t (e.g. “Load/save”). May I humbly suggest some consistency rules :
- no sub-level if there is only one subject
- no items on main level if there are already 1 or more sub-level(s).
For instance :
- sub-level “Default Dimension settings” under “Dimension” is the only sub-level : then move these items under main level “Dimension” and suppress the sub-level ;
- the items under “Graphics view” main level (with several sub-levels)could be in a sub-level named “General” ;
Actually, “Graphics view” main level is the only one which has both its own items and sub-levels )) ?

I would like to get a shortkey like ‘+’ to rotate text at 90° clockwise.

Nach einigen Überraschungen ....

Es ist möglich Layer in nicht eingefügten oder unsichtbar geschalteten Library Items unbemerkt zu löschen ....

Fallbeispiel 1:
Ich arbeite an einer Zeichnung die u.a. den Layer “Gelbe Linie” benutzt.
Ich füge ein Library Item ein was auch einen Layer “Gelbe Linie” hat.
Ich lösche - aus welchen Gründen auch immer - in der Zeichnung das Library Item weil ich es erst später wieder verwenden will.
In der Blocklist ist es natürlich immer noch verfügbar.
In der Zeichnung lösche ich den Layer “Gelbe Linie” da ich diesen nicht brauche brauche - habe aber natürlich nicht im Kopf welche Layer in meinen Blocks verwendet wurden.
Nach einiger Zeit will ich den Block (den aus der Library) wieder einfügen - dieser ist nun aber unbrauchbar da der Inhalt welcher auf dem Layer “gelbe Linie” war fehlt.
Das Library Item neu aus Library laden um das bereits existierende zu reparieren scheitert da das erste nicht überschrieben werden kann. Ich muss den ersten Block löschen um den neuen benutzen zu können.

Fallbeispiel 2:
Da das selbe (löschen der Layer) auch passieren kann bei unsichtbar geschalteten Blöcken kann es dazu führen das ich zig bereits positionierte Blöcke zerstöre und neu platzieren muss um meine Zeichnung zu reparieren.

Fallbeispiel 3:
Ich sehe in meiner Zeichnung einen Layer “Gelbe Linie”. Weiß nicht was das ist - schalte alle Layer unsichtbar außer “Gelbe Linie”. Klicke auf “Auto Zoom” um zu sehen was den auf “Gelbe Linie” ist. Finde nichts = also leer! Lösche Layer “Gelbe Linie”. Der Layer wurde aber von einem im Moment nicht verwendeten Library Block verwendet. Es gibt keinen Hinweis das ich damit ein Library Item zerstören könnte ....

Lange Rede kurzer Sinn: Wäre es machbar/sinnvoll Layer in Blöcken nur löschen zu können wenn ich mich im Edit Modus der Blöcke befinde?

Since this is not supported by Qt anymore, this would likely have to be implemented from scratch.

Es wäre Arbeitserleichternd wenn ich bei den Optionen für Bemaßungen (Prefix/Postfix) eigene Präferenzen speichern könnte so das diese in allen Zeichnungen von mir verfügbar wären.
Zudem wäre es wünschenswert dieses nicht nur bei den Prefix sondern auch bei den Postfix Angaben nutzen zu können was dann alle(?) Manipulationen erschlagen würde.

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

Es wäre schön wenn ich Werte wie zum Beispiel Längen von Linien direkt abgreifen könnte um diese weiter in Berechnungen verwenden zu können.

Beispiel:
Ich habe eine Linie konstruiert wobei sich eine Länge y ergeben hat.

Nun möchte ich eine Linie zeichnen die 5 mal y sein soll.

Linientool → Wert 5* eingeben und y durch Auswahl mit der Maus von dem vorhandenen Elements übernehmen.

Natürlich könnte ich die Geometrie Info benutzen um den Wert abzulesen oder auch über die Zwischenablage zu benutzen. Ein abgreifen mit der Maus wäre aber schneller, direkter und wahrscheinlich auch mit weniger Fehlern (Human error) verbunden. Wahrscheinlich auch genauer da QCad, denke ich, mit mehr Nachkommastellen rechnet, oder?

Feature request
See topic - http://www.ribbonsoft.com/rsforum/viewtopic.php?f=31&t=2015

Just a thought, but one that could be useful for machinists in particular - a measurement tool that can snap to a point as per usual, but then just displays the drawing coordinates in X and Y. This could be expanded to the dimensions tool set, so that you can click on a point and print the coordinates next to it.

I would appreciate an option for the library Browser that gives me the possibility to decide by my self to use the current (same name) layer in my drawing or overwrite it with the existing layers in the library item.

Imagine the possibility’s of this feature ....

Support disproportional scaling also for arcs, ellipses, other entities, not only lines and polylines with only line segments.

Provide keyboard shortcuts for options tool bar.

Under Linux, Windows Alt+Key shortcuts can be used.
Mac OS X does not seem to support this.

Wenn ich eine Zeichnung plane überlege ich mir natürlich im Vorfeld welche Blattgröße und welchen Maßstab ich verwenden möchte.

Wenn ich Templates (z.B. Zeichnungsblatt A4) für die Blattgröße öffnen könnte und dabei direkt einen Skalierungsfaktor (z.B. 10) vorgeben könnte hätte ich ohne Umwege gleich alles was man braucht. In diesem Fall ein A4 Blatt im Maßstab 1:10.

Im Grunde genommen das selbe was ich bereits mit Library Items machen kann ...

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?

It would be useful if a file of keyboard shortcuts to commands could be loaded.

Then a set of shortcuts identical/based on the Autocad keyboard shortcuts can be loaded, making it much easier for Autocad users to migrate to your product.

There does seem to be some future functionality planned here, with the shortcut ‘scheme’ selector in Program Preferences, but for the moment ‘Qcad’ is the only option available.

This strategy is used to great effect by Draftsight (but who trusts a big company like Dassault/Solidworks...)

Command ‘Lengthen LE’ will extend most arcs but not all (2 arcs in the attached drawing do not work)! There is no obvious reason for this from the users point of view.

Drawing Unit is in “Inch” but the Layer Data (Line wight) is in “mm” ....

I like it ... but maybe I’m the only one

A line with linestyle = dots and line weight = 0.00 appears in model space overly spaced, all other lineweights behave as expected.
Suspect other linestyles to behave in a similar fashion.

See attached drawing.

Suggested fix: use the same scaling for lineweight 0.00 as for lineweight 0.05.
