1407QCAD (main)Feature RequestLowSplines: add support for knot weights, start-, end tang...Assigned
0%
1 Task Description

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.

1464QCAD (main)Feature RequestLowOption button to access finer grid to snapAssigned
0%
1 Task Description

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.

1472QCAD (main)Feature RequestLowArc fit tool to improve large filesAssigned
0%
1 Task Description

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.

1577QCAD (main)Feature RequestLowPostfix for DIM / Remember last DIM Label ...Assigned
0%
1 Task Description

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?

1705QCAD (main)Feature RequestLowConnect certain actions and layersAssigned
0%
1 Task Description

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.

1 Task Description

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.

1888dwg2bmpFeature RequestLowAdd support to disable hatch rendering on "dwg2bmp"Assigned
0%
1 Task Description

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!

1903QCAD (main)Feature RequestLowSaving layer settings, e.g. visibility status, associat...Assigned
0%
1 Task Description

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.

1926QCAD (main)Feature RequestLowNo negative coordinate values ? (DO command)Assigned
0%
1 Task Description

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 !

1928QCAD (main)Feature RequestLowOptionnally 'Auto clean up' after generation of NaN / N...Assigned
0%
1 Task Description

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.

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

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.

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

0%
1 Task Description

QCAD Professional
Win installer 32bit
Version: 3.25.2.7 (3.25.2.7)
Internet: QCAD.org
Build Date: Dec 16 2020
Revision: e06f230
Qt Version: 5.13.2
Architecture: i386
Compiler: Unknown

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.

2213QCAD/CAMFeature RequestLowAllow editing Spindle Speed separately for each Toolpat...Assigned
0%
1 Task Description

Hello dear CAM developers!

I need to use the same tool at different spindle speed in a single machining file.
I would deeply appreciate if you could add a Spindle Speed edit field in the CAM Profile Toolpath edit window in order that each Toolpath can have its own Spindle Speed value (same as you did for Feed Rate and Plunge Rate)

FYI, the tool on my concern is a laser who’s power is driven by the Spindle Speed PWM signal.
I need to be able to do both engraving and cutting in a single file.
Alas! this laser tool is defined with a fix and unique number (99).
Therefore I cannot define different laser tools with different speeds.

Many thanks
Best regards.

2282QCAD (main)Feature RequestLowAdd a "Save As" command while editing blocks in placeAssigned
0%
1 Task Description

As a heavy mechanical drawings user, it would help a lot to have an option to exit a block saving as a new name and making it a new entity from that time ahead.

Example: if a have a lot of screws, one of then is behind another peace and need the to have some lines changed to hidden style lines, in the flow of the work is great if I edit that screw in place and when exiting have the option to save as a new block, to don’t mess with other entities of the same block that I don’t want to change. Yes, there is a workaround that is duplicate and rename the block prior to the editing, but a save as seems to work easier.

Thanks Andrew and team!

2293QCAD (main)Feature RequestLowinsert attributes into a point elementAssigned

1 Task Description

Would it be possible to extend the tool for importing points with a label so that when importing points into the drawing (as it is now), the attributes of the point are taken from the csv file and written to the point’s own properties? See attachment. This would extend the functionality of the tool and I assume that it would also lay the foundation for the possible re-export of such points from the drawing to a csv file, including all the details.

2301QCAD (main)Feature RequestLowRotate preview on/offAssigned
0%
1 Task Description

Hi,

I believe prior QCAD version 3.22.0.0 there was no rotating preview. The rotating preview shows the outcome regarding to the chosen center point. I know that it is also common for move/copy. However, for me it is very confusing and difficult to chose the correct center point for a rotation if I’m constantly been distracted by the most of the time overlapping preview of my selection. This said if the drawing is very detailed I have to zoom in extremely to be able to snap to the right entity. That wouldn’t be necessary without the preview. Additional rotate a large drawing selections will compromise the performance - CPU is going like crazy.

It would be nice to have an option to turn this preview on/off.

2338QCAD (main)Feature RequestLowShow non-QCAD custom XDATA optionallyAssigned
0%
1 Task Description

QCAD (before version 3.27?) used to show some custom XDATA, e.g. tag 1000, even for application names that are not “QCAD”, which for me was useful, so it’s somewhat of a regression. (I think it was broken when selecting multiple items, maybe that’s why it was removed.)

I suggest to bring that feature back, but maybe show it only when a single element is selected if that’s easier.

(As a workaround/hack I guess it would be possible to rewrite the required information as QCAD compatible XDATA externally I guess.)

QCAD. ver. 3.27.1.0 (3.27.1)
Qt version: 5.13.2
Architecture: x86_64
OS Windows 11

It might be useful to have the possibility to manage the references of the images contained within the drawing. A design could use recurring images, stored in a folder outside the one in which the design is located. Moving the drawing or folders (or changing the PC) will lose the folder references and the images are not displayed when the drawing is opened again.
I imagine the possibility to view the references of the images (and if necessary modify manually or with a pointer) with the option of: attach, detach, reload, etc., as in the example below (referred to ActCad - based on Intellicad technology)

When editing an existing toolpath to update the parameters of the selected tool, we can update the Feed Rate and the Plunge Rate, but I couldn’t find any way to update the Spindle Speed.

Even when using the Edit Tool KE button, we can edit parameters of the tool on concern but none of the modification is applied to the current Toolpath because as I see, tools parameters are copied fron tools definitions to a Toolpath only at creation of this Toolpath, but Toolpath are not updated accordingly.

When we use Lengthen/Shorten (LE) with a positive amount the result is clearly visible when indicating a side of an entity.

A Leader entity is stored similar as a polyline.
