1552QCAD (main)Feature RequestLowLayers: assign different color for printingAssigned
2 Task Description

Original request:


1567QCAD (main)Feature RequestLowAdd support for separate windowAssigned
2 Task Description

Hi, for multi-screen hosts it would be very useful to have additional windows while running the single QCad instance. Other applications like Palemoon, Evolution, Gimp are providing that already.
That would help a lot when working on multiple files and copying blocks between.

1663QCAD (main)Feature RequestLowFeature Request: Export Layers as New DrawingAssigned
2 Task Description


in many tasks in qcad I ended up exporting one or several layers into individual files for some cnc jobs or further processing. So the steps I usually do are:

  • select all elements on the layer
  • paste into new drawing
  • sometimes rename layer names or attributes
  • adjust dimension settings
  • save and give name for drawing

Sometimes I have up to 100 layers I need to export like this, so an automatic export for all would be time saving too. But very often a “single click” export method would also help a lot. (e.g. inside the layer list an entry in the right click menue like “save as new file”). Also a multiple selection would be handy if more that one layer should end up in the new file. (e.g. select the three layers that need to be in the new document, then right click and save as new file). Maybe this is too much of changes needed inside the layer list - so something like a separate layer export dialogue would make sense.

When exporting many layers some variables for automatic naming of layers and filename would make sense e.g. user can specify basename_%L.dxf to get the basename_layername.dxf or just an increasing number.

For layers and attributes it is often needed to give a layer a certain name or color for different cnc processes (e.g. engraving and cutting for lasers) or to put everything on layer “0” because of some old CAM software that only supports content on layer 0.

probably many more details would make sense that I didn’t think of yet...

kind regards

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”).

1983QCAD (main)Feature RequestLowTrim All or Bulk Break outAssigned
2 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.


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!

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.

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

704QCAD (main)Feature RequestLowOld Hatch FunctionAssigned
3 Task Description

It would be nice to implement the old hatch function as a tile function in parallel with the newer more industry standard hatch function. A tile function that would allow overlap +/- would be even better, and a great productivity boost, almost like an array within a set of bounds.

Thanks, Bob

3 Task Description

It would be nice to have an additional Radius Measurement tool with short leads. The current Radius tool shows always the lead line to the center of the radius what is in many cases not useful.

I’m not asking for a workaround ;-)

766QCAD (main)Feature RequestLowLayer List: Add "Lock All Layers"Assigned
3 Task Description

To improve useability/efficiency I would like to propose the following changes/additions to the layer list:

1) Combining the show and hide button into one button.

Clicking once will hide all layers, clicking again will show them all again.

2) A “lock/unlock” button.

Clicking once will lock all layers, clicking again will unlock them all again.

Regarding the icons I suggest that instead of show both the black and grey version of the eye/lock, you could switch between them depending on the state the switch-button is in. Also the mouse-over-text could/should change with the state.

952QCAD (main)Feature RequestLowDimensions: manually control arrow positionAssigned
3 Task Description

See drawing: I can’t seem to be able to manually change to the “To” variants – that is, override the decision of the label/arrow placement engine.

The circle in the attachment is a borderline example of when even just in this form I would more like it on the outside. If the drawing is crowded in that area, it would be even more useful to have it the other way around.

1165QCAD (main)Feature RequestLowNew Create Spiral ToolAssigned

A new tool to create Spirals would be great to have, with an option to restrict the decline to achieve to draw either Logarithmic or Linear styles.

Please see related topic:


1488QCAD (main)Feature RequestLowDimension text positionAssigned
4 Task Description

This one is a really important one for me, as currently I am doing a lot of dimension and annotation drawings.
I would like to request an option to be added to the dimension settings for both drawing and application settings to be able to choose whether the dimension text is to the right or left side or over the top or underneath the dimension line.
This would help tremendously when a lot of dimensions are needed!



1721QCAD (main)Feature RequestLowInsert table toolAssigned
4 Task Description

Hi Andrew,

I’m not sure whether this has been added or suggested already. It would be great to have a built in QCAD table tool for producing cutting lists or bill of materials etc. A dedicated table tool would be a real boost to QCAD Pro ;)

Many thanks


2018QCAD (main)Feature RequestLowLayer visibility setting per view/view-portAssigned
4 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.

1428QCAD (main)Feature RequestLowSnap middle of the minimum distance between two entity'...Assigned
5 Task Description


from time to time I need to place a circle etc precisely between two entity’s - what is a lot of construction work to get it correct. With the new “Info tool “Distance Entity to Entity” we have already the base for a new snap tool which could help to get rid of the time consuming construction process in cases like this. I would appreciate to get a new snap tool which is able to figure out the shortest distance between to entity’s and then will snap to the middle of it.

Pic 1: Given situation
Pic 2: Result after using this new snap tool

Would it make also cense to have a second new snap tool which works opposite for the furthermost distance between two entity’s?

1723QCAD (main)Feature RequestLowDetecting overlapping line / arc segmentsAssigned
5 Task Description

Add a tool to detect overlapping segments or lines and arcs.
Similar like the “overkill” command in other CAD systems.

763QCAD (main)Feature RequestLowHatching with just one clickAssigned
7 Task Description

My task: To hatch an area.

Right now, if I want to fill an area with a hatch pattern, I have to select all the enclosing objects (lines, arcs) and then I can select the hatch tool. That can be under some circumstances a tedious task.
To illustrate this, I created a simple example (see Attachment 1: Hatching.png).

Step 1: Create a rectangle.
Step 2: Draw four vertical lines.
Step 3: Select the four lines surrounding the first area. –> Problem! The horizontal lines are too long.
Step 4: Divide the long horizontal lines of the rectangle where the vertical lines touch. Now the lines surrounding the three areas can be selected.
Step 5: Hatch the selection. Done.

Just for fun try recreating my second example (see Attachment 2: Hatching2.png)

Therefore I would like to suggest a far more simple approach.

Step 1: Select the Hatch Tool.
Step 2: Click inside the area you would like to be hatched. Done.

Of course that would mean that the hatch style is already pre-defined and can be changed later, if needed.

In this way productivity can be increased by ... [fill in you own estimate] ... times.

Example 2 would need only 13 clicks to hatch all the areas (including the hatch tool button).

1788QCAD (main)Feature RequestVery LowNew snap: reference points of a block referencesAssigned

... but it looks like we have the issue now back with some kind of variation.

If I use the test drawing which I posted in 2013 ( FS#843 ) it works still as expected after it was fixed.

If I create a new block it won’t work in a new drawing nor in the old test drawing - no chance to snap to the Block Reference.

1900QCAD (main)Bug ReportVery LowRemote shares initially not accessible.Assigned
Task Description

My data files are stored on network shares (synology) with a GB link. QCAD Pro is run in Admin mode.

While in my Windows browser all remote shares are accessible (Green), in the QCAD file open menu they are initially shown as not accessible (Red). By accessing a specific drawing file in a remote share, the share will open and turn green.

Same behavior using ‘Open recent’. Always the message is given that the requested file does not exist, and the file is wiped from the ‘Recent Open’ list. Only if the share is first accessed through ‘Open’ with a random file, it will turn and a ‘recent open’ file for that share will open.

Drag and Drop from a remote share will never work.

1974QCAD (main)Bug ReportVery LowFile > Print Preview: Cannot move paper in new drawingUnconfirmed
Task Description

Yesterday I set up a Windows 64 bit install of QCAD Pro which shows the same bug I have been seeing for a while in the Community linux git repo.

Create a new drawing and then go to “Print preview”. Enable “Move paper postion”, the cursor changes to the hand icon, but the paper position is unable to be moved. Only by saving the drawing, exiting the program, restarting and reopening the drawing, will the “Move paper postion” function correctly.

Affected versions tested:

Windows 64bit installer download, as of yesterday.
Linux 64bit build from git, about 20minutes ago.

For what it’s worth, this bug is not present in this previous git checkout:

Version: (3.21.1)
Build Date:
Jul 2 2018

Qt Version:
gcc 6.3.1

Thanks for a great product.

2011QCAD Community EditionSuggestionVery LowUpdate QCAD CE SpatialIndex module to latest versionAssigned

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.

It looks like qcad is incompatible with versions above 1.8.5.

Are there plans to port to the new version?
