2140QCAD (main)SuggestionLowChanging navigation mode for mouse wheel doesn't change...Assigned
1 Task Description

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.

If tabs can be retained, text entities could support tabs.

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

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.

2115QCAD (main)SuggestionLowMove toolbars with negative positions to 0 positions Assigned
Task Description

As it can be seen in the attached image, QCAD toolbars may dock to a position slightly outside the visible area of the screen. After having docked there, I have not been able to move them any more. Their current position is just in the middle of the screen.

The position of the toolbars remains the same after the deinstallation of QCAD, shutting down, restarting the computer and reinstalling QCAD. I kindly ask for help.

Kind regards

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.

Task Description

The square symbol offered as symbol in DIM label is the only symbol which doesn’t adopt the layer color.
If I print a drawing in full color it leads to a black symbol in an otherwise colored dimension.

It is also the only symbol which has a solid filling what is confusing when you work with it in Model_Space ...

2092QCAD (main)Bug ReportLowcrash when changing shortcut in preferencesAssigned

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.

2063QCAD (main)Performance IssueLowBad performance while zooming inside layout block with ...Assigned
2 Task Description

Zooming in and out is lagging to the point of unusable. This is happening in a layout block with the cursor pointing inside geometry with hatches. When the cursor is pointing outside the geometry zooming works as expected.
The attached file has a very simplified testcase that shows this problem almost in the same way as a more complex drawing with multiple layers and hatches.

edit: I also attached the more complex drawing because it is a bit unclear to me where the lagging stops. Outside the viewport or outside the paper.

I just noticed the selection box has the same problem!

2060QCAD (main)Feature RequestLowDialog box for Layer StatusAssigned

2056QCAD (main)Feature RequestLowOption Duplicate layer (yy) inclusive all sub-layers.Assigned
Task Description

If I’ve to duplicate a layer with a bunch of sub-layer it’s a kind of a Sisyphus task to get it done.
Currently I have to duplicate each single layer. Then in an additional step I’ve to address each child layer to the proper parent layer.

Current lack:
Marked parent layer with all sub-layer / Duplicate Layer / only ONE layer will be duplicated.

With other words: If I have to duplicate a layer with 5 sub-layer it requires 11 steps to get a copy of that tree ... :-(

2048QCAD (main)Bug ReportVery LowMove / Copy to current layer fails when reference point...Assigned
Task Description

QCAD 3.24.2 / macOS x86_64 10.14.6

Starting with empty doc:
1. Draw any object (e.g. a rectangle) on layer 0.
2. Create new layer (”1”) with color, say yellow.
3. Select new layer
4. Select new object
5. Modify → Move / Copy
6. Click reference point
7. Click target point same as reference point
8. In “Move / Copy Options” dialog, select “Delete Original” and check “Use current layer and attributes.” Click OK.

The moved object stays on the layer it was previously on. Using “Move / Copy” as a quick way to move a selection between layers is not useful even though it appears to be the recommended way in a Google search.

Note: if “Keep Original” is selected instead, the copied object is placed on the current layer and the original object remains on its layer, as expected.

Note: if the target point is different from the reference point, the moved object is placed on the current layer as expected.

There are other workarounds too, cut / paste with “To current layer” checked seems to work, as does chaging the layer in the Properties Editor.

2034QCAD (main)Feature RequestLowPaint Properties to include modifying linetype scales w...Assigned
Task Description

Previous Feature Request #1285, dated 2015, incorporated in QCADPro 3.24. I regularly adjust linetype scales on hidden, centreline and phantom lines to achieve the best appearance on the drawing when printed. I note the Paint Properties feature copies all the attributes of the chosen line but does not copy the scale. I have to change the scale of each line, even after ‘painting’. This copying all Properties is something AutoCAD does. I know I could change the line to Hidden2 etc. and tick the ‘scale lines’ box in Drawing Properties but that is not always successful- copying properties is a quick and useful way of achieving the required result.

2021QCAD (main)Performance IssueVery LowCannot work with big dwg filesAssigned
Task Description

Openning a big file or doing any action in it, takes minutes to load.
Even dragging the scrollbar slightly left or right, takes mintues to redraw the canvas again, which makes QCAD un-usable for professional use.
Is there a way to make QCAD usable, after loading completed:
- Like suppressing edit until user says so,
- or taking snapshots of rendered canvases to another file and use it, as windows uses thumb.db ( for negative latency :P )

PS: I wish I could help a bit, but my hand are tied. I am just a java freak, I am opt to any idea of porting it to java, if she is still alive.

2018QCAD (main)Feature RequestLowLayer visibility setting per view/view-portAssigned
3 Task Description

In a medium complex drawing it’s often too much details to have all layers in a drawing visible at once. Also, it is of great importance to be able to have a single model to avoid duplication of work and risk inconsistency.

So i would like to create a number of views where each view has selected layers visible (that makes sense for the purpose of the view) and then assign the views to different layout blocks (using view-ports) in paper-space to be able to setup printing of several views on the same page/PDF

This also means that view-ports would have to be aware of what view they are displaying (if any besides the standard-view).
This will then make it possible for printouts of different views with selected layers visible (different for each view and view-port) and still have only one model. Today this is not possible.

As it is today the only limited workaround is to set the layers you want to display, print/PDF of that viewport on separate page, and then change it for the next page, and so on. The big drawback is that you cannot have two different views/view-ports on the same page with different layers visible. Also, for large drawing it is painful to have to do a lot of manual setup for each rendering of the complete drawing.

2016QCAD (main)Bug ReportLowOffsetting multi selection of polylines halts prematureAssigned

2014QCAD (main)Bug ReportLowFocus on Options Toolbar failsAssigned
Task Description

Scenario: e.g. Tools Move/Copy and Rotate switched to “use without dialog.

Launch within a drawing Move/Copy, use the Keyboard keys CTRL + Space to focus on the Option Bar - the field for Numbers is Highlighted and I can change it. Further navigation with keys on the keyboard depends on remembered option (copy yes/no etc what make a navigation possible or not. It looks like the navigation with the Arrow keys is focused on the canvas and sooner or later the courser will jump to the Command Line or Property editor. Same behavior with the Rotation tool.

Building with the bundled version, 1.8.5, works fine.

When I try to build using the system version, which for Mageia Cauldron is 1.9.3, the build fails.

1999QCAD (main)Feature RequestLowViewport: Add additional properties for controlling dim...Assigned
1 Task Description

When working with multiple Viewports with different scale it could be very useful to have extra properties controlling how dimensions are rendered in the viewport:

E.g an extra “Dimension Scale” under “Scale” in the Viewport selection’s ‘Specific Properties’ section, could allow having the same size when printed.
This Dimension Scale would be multiplied on top of the Scale value, but only for Dimensions rendering.

Toggle button for hiding any dimensions in the Viewport. Maybe this should be controlled by being able to specify a Layer that should be hidden in this Viewport only, then I could select my Dimensions layer here.

1983QCAD (main)Feature RequestLowTrim All or Bulk Break outAssigned
1 Task Description

This is a trim method I am missing in Qcad.

20 years ago it existed in CadKey.
You had a bunch of lines or segments.
You defined a (new) line or segment as cutter.
‘Trim All’.
You pointed at the side of the cutter entity to trim all intersecting at that side.

Pritty the same as in this topic:

Only in rare cases I can use Husky’s workaround as pro.
It all depends on what else is in the clipping rectangle that is needed to trim all intended.
If of no use all single crossing entities have to be chosen one by one.

1934QCAD (main)Feature RequestLowDiametric text - overlaidAssigned
Task Description

Diametric text is always placed above a horizontal measurement.

I often want to indicate both the inside and outside diameter of an object e.g. a wheel using diametric text. The text is overlaid and illegible.

To avoid text overlapping, I use Horizontal Aligned because I can control the position of the text to avoid illegible text.

A better method would be to alternate the placement of diametric text (alternatively) above and below a measurement so that in the majority of cases an overlap would be avoided.

Similarly for a vertical measurement, the text is overlaid and illegible.

When the angle is almost vertical, the angle controls the side the text appears however it also reverses the direction of the text (which is logical but not attractive).

Kind regards

Task Description


my setting for “Auto Zoom on load” is checked to on. That works perfect for me for most of my drawings.

1928QCAD (main)Feature RequestLowOptionnally 'Auto clean up' after generation of NaN / N...Assigned
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.

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.

1926QCAD (main)Feature RequestLowNo negative coordinate values ? (DO command)Assigned
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 !
