Hi,

I use a lot of “temp” layer to keep my drawing organized during a design session. Ad the end of the day (or week or month ...) I need to get rid of this “garbage” but unfortunately there is no easy way to delete all this layer in one go.
Most of the time those layer are invisible. The “important layer” are visible. If I could toggle all layer from visible in invisible in one go with a switch like “Toggle visible layer all” and then use “Select all” / delete / Purge unused layer I’m able do get rid of this stuff with just a few clicks.

The same tool would help to improve the workflow in the case that I just have to switch between all visible / invisible layer for testing / double checking / cleaning or what ever. Currently I have to toggle every single layer to get this done and if I work with many layer I need to have a perfect working memory (or a piece of paper with many notes!) to be able to restore the same desired working order.

And I’m confident - there are many more useful scenarios for a tool like this one ...

Attached DWG/DXF files are incorrectly read by QCAD.
They contain splines drawn using ZWCAD and saved as DWG/DXF version 2000.
Above splines are polylines created with autolisp routine which converts spline to polyline, so you can see how splines should actually be drawn.

First spline is created with fit points: 2,2 4,4 6,2
Then copied and applied weight of 2 on central control point.
Then copied again and applied weight of 0.5 on central control point.

Second spline is created with fit points: 6,2 8,4 10,2 with vertical start and end tangent.
Then copied and applied fit tolerance of 1 for fit points.

Third spline is created with fit points: 10,2 12,4 14,2 with horizontal start and end tangent.

Fourth and fifth spline are correctly drawn by QCAD.

Automatically set the draw order one lower than the lowest draw order of a border entity when creating a hatch. This should be a user preference, since not everyone might want that behavior.

Could it be possible to add a simple function to add a new empty drawing (like File > New) to Simple.js ? Thank you. (PS, this simple.js API is awesome, btw :D)

( I already have my own to simplify my scripts, but it does not seem to work correctly if I set action.setRequiresDocument(false); in the init functions
See more at http://www.qcad.org/rsforum/viewtopic.php?f=32&t=4203#p15203 )

Not sure how difficult this would be to implement but just wondered if it is possible to have an option in QCAD to change the opacity of a colour ?

Hi,

I am using mac version and I have annoying issue with trackpad.
I use qcad primary with my trackpad and under application preferences (Graphics View/Navigation), my setting is as follows.
Mouse wheel / two finger swipe: Scroll (Trackpad...
Enable pan gesture : unticked (found that enabling this often goes into pan mode when I am just moving my pointer around)
Limit zoom and scroll to prevent overflows : ticked (hoping that this would prevent weird zooming issue. I will describe what I am experiencing later this page)
Reverse mouse wheel direction for zoom :unticked
Mouse wheel zoom factor: 1.02

Things work as expected:

• panning with two finger swipe

• and the rest

Issue I am experiencing:

Often, when I am zooming in and out with two finger gestures, the view suddenly sets to some weird state and my drawing goes off the ruler.
The mouse point remains where it is.

Workaround:
Reset viewpoint with autozoom and navigate around.

Expected zoom behaviour:
I expect viewpoint to zoom in / out at where my mouse pointer is or at least the centre of current view point.

Hi,

I use eagle cad for pcb designs and I like its ability to snap to finer snap to grid when pressing option button (ALT in windows).
I am fine with auto grid setting, however, it would be good to also have a way to access finer grid when pressing down option button.

For example, when zoomed out, grid is 100mm apart.
When pressing down on the option button (ALT in windows), grid switches to finer 10mm.
This will save me time, zooming in to access finer grid to snap to.

Would not it be possible to create a kind of template for printing?
We draw our room without cartridge. The cartridge will automatically appear when printed. The scaling could be automatic so that it goes in the A4 and therefore also will post the scale automatically. The name of the play could be the file name, date last saved after it the rest of the information that would be to add somehow (material index, designer, ...).

Original suggestion:

Bonjour,

Ne serait il pas possible de créer une sorte de template lors de l’impression ?
On dessine notre pièce sans cartouche. Le cartouche s’affiche automatiquement lors de son impression. La mise à l’échelle pourrais être automatique pour que ca rentre dans le A4 et donc l’échelle s’afficherai aussi en automatique. Le nom de la pièce pourrais être le nom du fichier, la date du dernier enregistrement après c’est le reste des infos qui serait à ajouter je ne sais comment (matière, indice, dessinateur, ...).

Large files/large entities perform bad in QCad. There are many dxf files that are created with thousand of lines that perform reasonable in other cad’s/cam’s that qcad cannot match.

One very useful tool, that could be added would help to improve qcad performance and at the same time enlarge the dxf quality (by replacing thousand of files by arcs), would be a tool called “arc fit” where, when possible and under a determined possible error margin (user selectable) creates arcs replacing the existing lines.
This would improve the file work in QCad also improves CAM software that would work after QCad, that I think is important for many users.

For example, if it is needed to use qcad to generate toolpaths for letters, after exploding letters, the output is almost impossible to work due to the number of lines that are created. Having arcs instead of lines would greatly improve qcad use.

It would be so useful to have an option to be able to detect duplicates within a given selection.

Two useful commands make it necessary to

1-”delete all the history of the command lines without terminating QCad” ; and

2-”export attributes to the CSV file as exported to the Blocks List”

Hello
It would be great when you can add a function to export a selected object as a list of points.
Is it possible to add?

Autodes DWG TrueView 2017 has this function and it is very useful.
Here you can see a screenshot of this function.

Hi,

unfortunately I need to use from time to time different Units in a drawing. It works nice with the Scale possibility but to keep my drawing readable I need to label then the DIM accordingly. Sadly I don’t have a Postfix option so I work with a workaround what means I use <>”, or <>’ and <>mm in the Prefix field. If I then terminate the DIM tool and start it again I will loose my settings except the Scale Factor.

May I ask for an additional Postfix option or/and a remember functionality of those fields?

... please see below:

Add support for polygonal viewports

https://www.qcad.org/rsforum/viewtopic.php?f=89&t=5241

Add intersection, union, difference, XOR operations for closed polylines.

When dimensioning my drawings I always want the dimensions to be on the dimensions layer.
When adding text I want the text to be on the text layer.
When drawing an infinite line it is always a construction line, therefore I want it to be on the construction line layer.
When drawing a line segment it almost always is on my outline layer.

So I propose a new option to bind certain actions to certain layers.
Whenever those actions are selected the layer should automatically be switched.

I can imagine this being implemented in the General→Tool Settings menu, where the short cuts are defined.

Add attribute value “By Parent” for color, line weight, line style for child layers.

Hi Andrew,

we know that you need to have always software performance in your mind to decide which features / tools can / should be implemented and on which way.

I really appreciate your effort to find the best middle way between software features and performance but I think also it’s a tough call to appraise worldwide the overall customer equipment to make the software workable to the best for everybody. That isn’t possible without compromise.

Maybe it would make sense to think about a new dialog in the “Application Preferences” to let the user decide what kind of feature are absolutely needed regarding to his/her work-task / equipment. I don’t mean that you need to cover every single thing but the main “performance jeopardy’s” should be covered with an on/off switch.

Yes I know - that isn’t done in 5 minutes but I think that can make your life easier in the long run and will cover even more customer.

Just my two cents. ;)

Automatic change of icons in the Library Browser from black on white to white on black or vice versa depending on the background (white or black; light or dark) in QCAD main window.

There is the Synchronize attributes feature which works well. But It affects only block references in the active layout(modelspace, block layout). If I want to synchronize attributes of block references in in another blocks, i have to manually go through all blocks and run synchronize attributes feature. That is the reason I would like to modify Synchronize attributes feature to affect all block references in a drawing, or add new Deep synchronize attributes feature.

Hi,

we have already this nice tool “Angle bisector”.

I would really appreciate if we could get the same function for parallel lines to place a line exactly in the center of both lines.

Thanks.

Hi!

A friendly request to add an option to disable hatch rendering on “dwg2bmp” conversions.

Depending on the nature of the conversion and the density of the hatch, this may render unintelligible images (see attachments). The option could look like “-t, -nohatch” to indicate hatches should be hidden before rendering. This could potentially become an option too for “dwg2svg” or “dwg2pdf.”

Amazing product, thank you so much!

In a medium complex drawing it may be too much details to have all layers in a drawing visible at once.

Instead a number of views would be created that saves not only zoom level and position but also what layers are visible and not (as appropriate for the purpose of that particular view). This is very cumbersome (to the extent it is not really realistic) to achieve today and requires a lot of duplication of both model and layers.

The advantage of adding this is the ability to have only one model (with multiple views) and avoid duplication of work and the risk of inconsistency inherent with many copies of the model.

As a further (and natural extension to this) would be the ability to used this functionality with view-ports to be able to create (possibly many) paper-spaces from a single model. This would however require view-ports to be aware of what view they are a window into. A single change in the model would then propagate to all defined view-ports and paper-spaces.

Just starting with QCAD, for some hours now - really excellent user interface (compared to other low budget CADs, like DCAD, or BeckerCAD...) !

Surprisingly, point coordinates - entered via the command line, and shown with correct positions on the drawing- are not displayed correctly with the ‘dimordinate’ (DO) command.
There are no negative values, even when the center point (0;0) is right in the middle of the drawing, so points left and below should have !

Some functions / methods can generate some sort off entity or part with NaN / Null / Null-lenght ... props.
Some explicitly don’t and test their actions with isNull().

As these serve a purpose in some processes, trails of them can be part of the results.
For some users Null / Null-lenght are meaningfull, for other users these produce errors down the line.
In a few cases its a desirable feature eg. controlpoint spline.
(Allthough there are no Null props involved with equal successively controlpoints)

Many problem post on the forum are related to Null - Zero and so on.

In some cases it can’t be undone by re-editing the drawing.
https://qcad.org/bugtracker/index.php?do=details&task_id=1925

If it can’t be undone by Undo/Redo it is a bug.
https://qcad.org/bugtracker/index.php?do=details&task_id=1757

In some cases there is a difference noticed after file save-close-open.

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

Hi,

It would be less confusing to read messages in the command line protocol if it would use the same coordinate separators like the settings below Application Preferences / General / Coordinate Format.

This example shows the “Absolute Cartesian Coordinate” but of course all corresponding format settings should be used within messages.

Absolute Cartesian Coordinate: Setting = semicolon (;) but the message will use division (/).

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.

“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,

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.

Case:
Drawing with text, zoom in and out with one of the common methods, text will disappear in certain zoom level

Same drawing zoomed in and out in 3.20.0.0 doesn’t show this effect - works just fine.
