2091QCAD (main)Feature RequestLowToggle redrawing of hatches Assigned
2 Task Description

Because modifying hatches have lag issues I’d like to propose a toggle that turns of the redrawing/rendering of the hatch. Especially while modifying the hatch.

The hatches always have a boundary that can be worked with right? So when we move or stretch the hatch we can still see the boundary and its handles to perform all the actions.

This could be a new view mode that turns of the view of the interior/pattern of the hatch but leave the boundary of the hatch.
Or the draft mode can be extended to include simplified hatches while modifying.

2107QCAD (main)Feature RequestVery LowAdd a button to the tool bar to allow for a quick backg...Assigned
1 Task Description

I find myself with reasonable regularity needing to change the background color between black and white. It would be much more efficient to have a toggle button on the ribbon to make this sort of instant (kind of like the “screen based line types” button works but make it for background color and just between black and white or let people define their dark and light themes and toggle the background between the two.

2127QCAD (main)Feature RequestLowSnap for predicted intersections while using "Restrict ...Assigned
2 Task Description

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.

2128QCAD (main)Feature RequestLow"Create Library Item" "Save As" dialogue doesn't rememb...Assigned
2 Task Description

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

2161QCAD (main)Feature RequestLowMake Polyline from Selection (OC) configurable for simp...Assigned
1 Task Description

QCAD Professional
Win installer 32bit
Version: (
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.

Select the previously selected entities.

2189QCAD (main)Feature RequestLowVertically and/or diagonally stacked fractions option.Assigned
1 Task Description

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

1 Task Description

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

2191QCAD (main)Feature RequestLowExtend the functionality of the Reorder toolAssigned
3 Task Description

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.

1 Task Description

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

2195QCAD (main)Feature RequestLowSaved views include memory of blockAssigned
Task Description

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.

Task Description

We currently have a paper-space using two viewports with different layers from the model-space frozen. Unfortunately in the pdf output the layers which are frozen show up.
dwg2pdf should obey the specific frozen layer for each viewport

1887dwg2bmpFeature RequestLowAdd "-max-lineweight" option for dwg2bmpAssigned
2 Task Description

Hi there,

A friendly request to add the option to set a maximum lineweight for raster conversions via dwg2bmp.

Depending on the LW configuration of the CAD file, rasterization operations sometimes yield terrible results (see attachment). This would also mirror the similar “-min-lineweight” options available on “dwg2svg” and “dwg2pdf” (although not on “dwg2bmp”).

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


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!

Task Description

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
