721QCAD (main)Bug ReportLowVertical dimensions imported as horizontal dimensionsAssigned

Task Description

Vertical dimensions created with 3rd party applications are sometimes imported as horizontal dimensions with length 0. Changing the angle in the property editor fixes the problem.
Problem occurs in QCAD 2.2 and QCAD 3.0.

Task Description

It would be nice to get:

In the Create Library Item task → “Save as” a remember Function for the last chosen Path to save the Item ... or a default path what is the same like the settings in the Application Preferences.
Right now you have to navigate again and again for every item what you will save in the same directory. If you have to save 20 items - it sacks ;-)

Also would it be nice for an easy “Clean up” to have the possibility to delete items directly in the Library Browser window.
Right now you have to use extern Programs like the Windows explorer to move or delete items.

705QCAD (main)Bug ReportLowVerwaltung Library Resourcen und Favoriten ....Assigned
0%
Task Description

Ob dies ein Feature Request oder ein Bugreport ist weiß ich nicht ....

Hier meine Gedanken ....

In den Application Preferences kann ich mehrere Library Sources vorgeben. Ich habe eine auf dem HD und eine auf einen USB angegeben.

Wenn ich nun QCad auf der HD ausführe habe ich beide Ressourcen zur Verfügung. Schön! Natürlich habe ich auch im Library Browser meine Favoriten von beiden Ressourcen angegeben.

Wenn ich nun aber den USB entferne zeigt mir der Library Browser immer noch beide Resorcen als Name an - schalte ich nun um auf die USB Resource bekomme ich keinerlei Hinweis das diese momentan nicht zur Verfügung steht. Es passiert einfach NIX ;-) Es wäre schön wenn ich hier eine “Nicht verfügbar” Meldung bekommen würde.

Wenn ich nun meine Trotteligkeit bemerke und den USB wieder einstecke habe ich logischerweise wieder meine Library zur Verfügung ..... nur die auf den USB Stick verweisenden Favoriten sind auf Nimmerwiedersehen verschwunden. Die auf dem HD bleiben erhalten!

OK - um es ganz rund zu machen ein anderes Szenarios in “Steno”:
QCad Start vom USB - > Library Favoriten anlegen auf USB Library - > QCad schließen - > USB entfernen → QCad auf HD starten - > Library Favoriten auf USB sind verschwunden - > QCad HD schließen - > USB einstecken und QCad von USB starten = Favoriten auf USB bleiben verloren!

Wäre es hier nicht möglich die Favoriten Information dem USB mit auf dem Weg zu geben? Wenn ich eine Favoriten Auswahl auf dem USB nicht kontrollieren kann macht diese Möglichkeit kaum Sinn.

Task Description

Hatched block loses hatching when using isometric projection tool:
See -http://www.qcad.org/rsforum/viewtopic.php?f=32&p=7063#p7063

Is this normal behaviour here? or a bug?

675QCAD (main)Feature RequestLowOption for fixed Text and Dimension heights ...Assigned
0%
Task Description

I think it would be nice to have the possibility to decide a fixed Text and Dimension (inclusive Arrows) height what is not affected by the Print scale. That means: If I have a given height of 3,5mm it will always be printed with 3,5mm - no matter what the scale for the printing is.
Yes, I see also the problem that I could run in space problems after I twitch to the Print preview - but that will also happen when I change the Text hight in the preferences for a 5:1 printing.
Maybe this Feature Request doesn’t looks important if you are usually working with Metric Units but if you have to handle Imperial Units then it is a pain in the back to make always the calculation to get the same heights.
Try it by your self; 3,5mm = 0.137795” = 1”:1” Now I like to print it in 1”:256” ops - to small - ok 1”:64” ... no, to big, maybe 1”:128” .......and QCad can’t remember the previously numbers. ;-)

639QCAD (main)Feature RequestLowAbility to load a file of keyboard shortcutsAssigned
0%
Task Description

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...)

637QCAD (main)Feature RequestLowViewports / View ListAssigned

Task Description

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?

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.

0%
Task Description

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?

564QCAD (main)Feature RequestLowSettings organisation in levelAssigned
0%
Task Description

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 ;-))) ?

0%
1 Task Description

Andrew,

The _DatumFilled Block used by Datum entities (DT) is considered as not used and is purged by Purge Unused Blocks (BP).
There is no block association for these special types of arrowheads in QCAD.

After purging the Datums are not immediately updated but the special arrowheads will eventually disappear. Adding new Datums will not fix that.

Not problematic because the _DatumFilled Block is re-created on save/reload when Datum entities exists. Datums are updated.

Probably not OS or version related.
Related forum topic: https://www.qcad.org/rsforum/viewtopic.php?f=89&t=10694

Best solution would be to support different types of arrowheads and all related:

2541QCAD (main)SuggestionVery LowConsider the unit "Microinch" to be non-metricAssigned
0%
1 Task Description

Andrew,

One Microinch is equivalent to 25.4 nanometers and I don’t consider that to be metric.

RUnit.isMetric(this.getDocument().getUnit()) returns true for RS.Microinch or value 8.

https://github.com/qcad/qcad/blob/master/src/core/RUnit.cpp#L145-L155
Returns false for: RS::Inch ; RS::Foot ; RS::Mile ; RS::Mil ; RS::Yard
... and true for all the rest.

Also see last note in: https://www.qcad.org/rsforum/viewtopic.php?f=31&t=9506&p=38295

Not to be confused with RDocument::isMetric() because that returns the measurement system unless that is RS::UnknownMeasurement what is rather impossible with drawings created by QCAD.

2540QCAD (main)Feature RequestLowRetain original handle when Hatch properties are change...Assigned
0%
1 Task Description

Andrew,

When we alter about any property of a Hatch entity it seems to be recreated with a newer/higher handle.
This doesn’t influence the drawing order in direct.
But already changing the drawing order of a Hatch it is recreated as a new entity.

It starts to matters in drawing order when there are multiple entities with the same drawing order and that after save/reload. Entities with the same drawing order then receive a new drawing order based on the original but sequentially increasing based on handle.

Because a Hatch is recreated with a newer/higher handle each time a property changes it will thus always end up above the others with the same order even when the original was created earlier.

This is more pronounced when copying/pasting entities from a source to a target drawing.
The original Hatch drawing order is retained but it will always be above existent entities with the same drawing order in the target drawing after save/reload.

Most other entities are probably just updated in situ.
It is unsure to me at this point if merely updating a Hatch is even possible.
And perhaps this is related to the addObject ForceNew flag what is false by default.

Regards,
CVH

2538QCAD (main)Bug ReportVery LowWeight 2.11 French translation typoAssigned
0%
1 Task Description

Andrew,

When switched to French I detected a typo in the drop down box for Lineweight.

Weight 2.11mm is listed as 1.58mm {2.11m?}
https://github.com/qcad/qcad/blob/master/ts/qcadcore_fr.ts#L1228-L1229
Also see attached image file.


May I ask why only ISO types have a comma instead of a point in French.
The use of a comma is uncommon in the Property Editor even when that is the native decimal separator.
I also detect an extra space between the value and ‘mm’ and that only for the ISO types.

This only occurs in:
https://github.com/qcad/qcad/blob/master/ts/qcadcore_fr.ts https://github.com/qcad/qcad/blob/master/ts/qcadcore_pl.ts https://github.com/qcad/qcad/blob/master/ts/qcadcore_pt.ts

2507QCAD/CAMFeature RequestLowAdd Toolpath from LayerAssigned
0%
1 Task Description

I’ve been able to make this work as proof of concept very easily, but many of the functions are inaccessible/difficult to override from post-processors.

Desired functionality:

1) Enable “Add Profile Toolpath” UI elements all the time (remove setRequiresSelection)
2) CAM Profile Toolpath Dialog: Drop-down menu of available Layers. First option “By Selection Only” 3) “By Selection Only” continues to pass EntityIds of selected objects (existing functionality)
4) Choosing an active Layer will use the Layer as source of EntityIds
5) Any changes to Entities on a Layer will result in those new/removed/changed objects being re-generated without having to manually select and update the tool paths. Either do not recover list of EntityIds from the ToolpathBlock, and instead use “live” each time it’s regenerated, or additional functionality to determine if a LayerId is associated with the Toolpath, and then lookup EntityIds.

I assume the persistence of the Layer selection would be available within the Toolpath, so that it will automatically update EntityIds every time a Toolpath is regenerated, without having to select Entities and updating the toolpath manually.

For large projects, being able to force select objects based upon layer dramatically reduces mistakes and speeds up the workflow.

Thanks

On behalf of user Kmeelo

Polygonal Area adds measurements text with 12 decimal digits and then as short as possible.

Current formatting path see: https://www.qcad.org/rsforum/viewtopic.php?f=32&t=10450&p=42833#p42805

Related forum feature request: https://www.qcad.org/rsforum/viewtopic.php?f=31&t=10458

I also see a misconception of the term ‘precision’.
Numbers precision is the amount of significant digits disregarding the position of the decimal point.
12 decimal digits is about the largest precision for numbers with 5 integer digits.

Andrew,

It took me a while to find the source of a certain freak bug I encountered.

With radii 1341.35667735 and 26 the relative tolerance is 0.00683678 and exceeds the former used fixed tolerance of 1e-4.

These arcs will then be considered to be tangent and the intersection point is 0.31024 units to the left of where we expect it.

I had already expressed my reserves on the relative tolerance but that was already a better solution for small arcs:
https://www.qcad.org/rsforum/viewtopic.php?f=33&t=8775&p=34907#p34907

We could limit the tolerance by:
A- The smallest of the fixed and the relative.
B- A relative tolerance based on R2 there circle 1 is forced to be the larger one.

This will never account for the position in the plane.
At a certain point the tolerance will be less than the accuracy/certainty of the values.

Andrew,

Related topic: https://www.qcad.org/rsforum/viewtopic.php?f=32&t=10094

When entering 1’ 1’‘ in an input field.
- As the size of the rectangle in the topic
- As the length property of a line selected in the drawing
- ....

Returns 13 in a drawing in mm.
And also in a drawing in inch what turns out to be correct.
But also in a drawing in foot.

Similar, entering 1’ with a drawing in kilometers it returns 12 units = 12 kilometers.

Andrew,
For more detailed description please refer to:

In the included screen grab below, left is when drawn cubic, closed periodic, from 4 points.
Right is when the file is re-loaded.

It is hard to select the incorrect shape when pointing near it ... Probably it is referring to the correct internal shape.
After drawing it explodes to a Null length polyline with 2 identical vertices.

I can’t include the error in a file as it reverts on re-load.

The same issue exist for quadratic, closed periodic, from 3 points.

CVH
