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.

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.

Task Description

E.g. 0 degrees at the top, clock-wise for positive direction, alternative angle units.

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 ... :-(

2057QCAD (main)Feature RequestLowMultiline toolAssigned
Task Description

2060QCAD (main)Feature RequestLowDialog box for Layer StatusAssigned
Task Description

So far, layer status has only been implemented very rudimentarily.
I wish something like a dialog box in which you can choose for each layer status, which layers belong to it and which not.

It may be useful to insert the “image cropping” function both in top / bottom - right / left mode, and with polyline

2087QCAD (main)Feature RequestLowMore options for "Paste along Entity" [PE]Assigned
Task Description

“Paste” has already the options: To current layer, Overwrite layers, Overwrite blocks.

Would be a nice time saver to have the same options for “Paste along Entity” too.

2091QCAD (main)Feature RequestLowToggle redrawing of hatches Assigned
1 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.

Also see the discussion

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.

1801QCAD (main)Performance IssueLowlow perfomance in paper space and viewportsAssigned
Task Description

Improving the performance of the exceptional use of the processors when switching from the model to the paper space (testing with the attached file) the functionalities of the commands for the viewports are too low in the paper space.

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.

2063QCAD (main)Performance IssueLowBad performance while zooming inside layout block with ...Assigned
1 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!

1323QCAD (main)SuggestionLowImprove command line support in QCADAssigned
Task Description


As a typical command line draftsman (still using acad10 for dos, since microsoft doesn’t supoort Win NT anymore),
I noticed a severe lack on command line acces in QCAD.

For example I find the icon and pixel selecting methods within qcad very confusing and rude.

With the normal cad Select command I can select exactly what en how I want it.

I intend not to be rude, but I find my drawing screen littered all over with all kind of very specialist menu’s,
tools and options. Sorry, I just want to make a drawing at the natural intuitive way, as with a pencil.
So I use command line Commands, such as Move, Copy, Change, Select, a.s.o.
For a ‘Command scripting’ user (-batching is a different tool!-),
it seems to me logical these basic commands should be accessable.

1368QCAD (main)SuggestionLowContext Menu - suggestionsAssigned
1 Task Description

I love using the context menu, speeding up my workflow indeed.

I would like to suggest that we have the added option to show only icons if desired and also that maybe an option to save and show commonly used tools!

Maybe the context menu could be configurable to show two columns, one for the normal last used tools and the othjer one for the user saved tools?

What do you think?

1469QCAD (main)SuggestionLowCartouche automatiqueAssigned
1 Task Description

Would not it be possible to create a kind of template for printing?
We draw our room without cartridge. The cartridge will automatically appear when printed. The scaling could be automatic so that it goes in the A4 and therefore also will post the scale automatically. The name of the play could be the file name, date last saved after it the rest of the information that would be to add somehow (material index, designer, ...).

Original suggestion:


Ne serait il pas possible de créer une sorte de template lors de l’impression ?
On dessine notre pièce sans cartouche. Le cartouche s’affiche automatiquement lors de son impression. La mise à l’échelle pourrais être automatique pour que ca rentre dans le A4 et donc l’échelle s’afficherai aussi en automatique. Le nom de la pièce pourrais être le nom du fichier, la date du dernier enregistrement après c’est le reste des infos qui serait à ajouter je ne sais comment (matière, indice, dessinateur, ...).

Task Description

When selecting multiple blocks that contain the same attribute names, attribute properties appear with the values of the last selected block instead of “various”. I do not know if this is a “bug” or developer option, but “various” would be better in my opinion.

1789QCAD (main)SuggestionLowApplication Preferences / General / Performance :0Assigned
1 Task Description

Hi Andrew,

we know that you need to have always software performance in your mind to decide which features / tools can / should be implemented and on which way.

I really appreciate your effort to find the best middle way between software features and performance but I think also it’s a tough call to appraise worldwide the overall customer equipment to make the software workable to the best for everybody. That isn’t possible without compromise.

Maybe it would make sense to think about a new dialog in the “Application Preferences” to let the user decide what kind of feature are absolutely needed regarding to his/her work-task / equipment. I don’t mean that you need to cover every single thing but the main “performance jeopardy’s” should be covered with an on/off switch.

Yes I know - that isn’t done in 5 minutes but I think that can make your life easier in the long run and will cover even more customer.

Just my two cents. ;)

1915QCAD (main)SuggestionLowViewport does not rotate view-port when changed in pape...Assigned
Task Description

To reproduce

1. Select a new view-port in model-space
2. Select the appropriate paper-space
3. When the paper space opens change the angle of the viewport.


The object in the viewport changes but the viewport itself remains unchanged


That both the view-port and the object changes angle as the angle is updated


If you abort the placement (but keep the angle) and go back to model-space and then redo the operation the view-port is rotated along the angle. It seems that the viewport only picks up the initial angle once the paper-space is open and ignores any changes thereafter


1. Select the view-port per normal in model-space
2. Open the paper-space and set the wanted angle but do not place the view-port in paper space
3. Abort the placement on paper-space and redo the whole operation

Once the paper space is opened again the view-port will have the chosen angle

2072QCAD (main)SuggestionLowInserted and flipped block mirrors text and dimAssigned
Task Description

Text and/or DIM used in blocks will be mirrored if inserted with a vertical/horizontal flip option.

Text/DIM which was successfully used in previos QCAD versions are now mirrored if they are loaded in the current version.

Version 3.23.0 doesn’t shows this behavior.


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

1877QCAD/CAMFeature RequestLowPost Processor TutorialAssigned
Task Description

Hallo Andrew,

I am still busy on the never ending G-code story. Doing so I wrote a small Post Processor Tutorial for all those nerds who wants to write their own. If you like it you might add it to QCAD. However, since English is not my native tongue I suggest checking it would be wise.

Meanwhile I have downloaded the source code, and could not find the CAM’s Drill-path-script. I am now using a negative Drill Cut Depth to set a Laser Dwell time, were as a field “Dwell Time (in seconds)” in the Drill-path would be more appropiate. Is this script open source available or is it part of ‘closed part’ of QCAD?
