1100QCAD (main)Feature RequestLowAdd drag dimension (snap) along dimension lineAssigned
1 Task Description

In Autocad when making a dimension when left clicking to place the dimension there is the possibility to drag the dimension to either side of the dimension. This is also possible with Qcad dimension, but it losses the snapping and does not extend the dimension line out to the dimension text.

This is very useful when the two lines the needs a dimension are close together, or overlapping with another.

Attached is two images one for autocad and one for Qcad

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.

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

639QCAD (main)Feature RequestLowAbility to load a file of keyboard shortcutsAssigned
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...)

1473QCAD (main)Feature RequestLow"Partial" circular/radial dimensionsAssigned
Task Description

This is kind of related to FS#952, or rather a superset of it.

Consider the situation in the attached image. There is a perfectly good, albeit really shallow arc, making the radius somewhere in the vicinity of 600 millimeters, and the radial dimension being drawn accordingly.

Considering the other dimensions of the part, this is completely unusable, even to work with, really, but definitely so when it needs to be put on paper.

It would be nice to have some sort of “partial” (for my lack of a better word) radial/diametric dimensions where the dimension length can be adjusted.

Considering that this can be done with Leader, maybe a better (more generic) solution would be for Leader type dimensions to have options so they could automatically generate labels for various dimensions of a selected entity – sort of like having the Prefix/Tolerance/Scale options the other dimensions have, and have some additional fields there for selected entity and maybe dimension type (for example, radial or diametric for an arc-type entity).

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

Default Path for “Create Library item from selection” / “Save us” is C:\Programme\QCAD pro 3.1.6 ...
... regardless of the settings in the “Application Preferences / Library Browser / for Library Sources.
And QCAD doesn’t remember the last path choice ....

If I have to save 50 Library Items I have to navigate 50 times thru my system to find - the same place.

It would be nice if QCAD would point in first place to the Library Source or, at least, remember the last used path ... ;-)

Would it be possible to have a clip to circle tool also please?



1870QCAD (main)Feature RequestLow Stretch tool / option to turn selection restriction on...Assigned
Task Description


since 3.19.2 the Stretch tool looks for any selection and follows the specification “Only stretch selected entities if there is a selection”.

That is a nice feature but it leads many times to confusing because I have to deselect a selection just because I need to use the stretch tool on something else on the fly. The same if I “forgot” a selection outside of my zoom which is still important for me. The stretch tool just won’t work without any message why not. My routine now is that I terminate every selection just before I use the stretch tool just not to be surprised by “why isn’t it working”?

It would be nice to have in the Stretch option bar a checkbox to turn the “only selection feature” on or off. QCAD should remember that setting.

1203dxflibBug ReportLowImages not saved (dxflib)Assigned
Task Description

I am doing a bit of landscaping and using a (big) ortophoto as one of my layers in order to sanity-check on the ground measurements.

The layer contains a point and the image and nothing else.

The image is a 8MB file: “PNG image data, 4200 x 2980, 8-bit/color RGB, non-interlaced” and it is scaled to 210 coordinate units (meter) horizontally in the drawing.

With approx 50% probability the image disappears during Save, as see for instance in this diff of the DXF file:

      - 20

      -  0

The point in the same layer does not similarly disappear, the bug only seems to affect images.

I have seen this bug from version to git as of yesterday (63e06c778926a803bdfbffdf27b8c24d41511072).

I have not been able to correlate the bug with anything.

Looking closer at the DXF file (attached), there seems to be some residuce of attempts to insert images in protected/invisible layers, so this may be some kind of refcounting issue.

(Any chance of getting FreeBSD into the “Operating System” field ?)

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

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

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”).
