598QCAD (main)Feature RequestLowSupport tangents between ellipsesAssigned
1 Task Description

To add support for drawing tangents between ellipses.

See topic:

1098QCAD (main)Feature RequestLowSupport for set of layersAssigned
Task Description

Many constructions refer to a basis of elements, which stay constant in all follow-ups. As an example there is a floorplan and I would like to create different variations of room layout (e.g. A and B). In my example the basis consists of 30 layers an each variation needs 10 further ones. At last there are 50 different layers in my drawing. Designing layout A needs layer 1 to 30 (basis) and 31 to 40 (A) to be shown, but 41 to 50 (B) must be invisible. Now I modify Var.B which makes me to single click the visibility of 31 to 40 (A) to be not shown and 41 to 50 (B) to be shown. You’ve got it?

It would be great help, to save the set of all shown layers by an individual name in a pulldown-menu. Visibility of my variations could be chosen by userdefined “set of layers”, e.g. “Var-A”, “Var-B” and “Var-A_but_different”. In this way I pick just one set-name in my pulldown-list instead of marking and demarking between countless layers.

In my opinion this tool would be a small aspect in QCad but a giant leap for user-pleasentness ;-)

Radek (iMac (Retina 5K, 27-inch, 2017), Catalina 10.15.7 (19H114)

My system/installation saves black as #4c000 (dark red)

When using single primary colors these get reduced to #4c, #7f, #99, #cc & #ff.
The threshold for that are #00, #65, #8b, #b2 & #e5
See: DimColorScale (png & dxf)

8 standard CAD colors fail saving correct
Black (something with #4c)
Dark Red, Dark Green, Dark Blue, Dark Cyan, Dark Magenta, Dark Yellow
(#80 turns #7f)
& Gray
(#adadad instead of #a0a0a4)

As with Gray, when mixing the 3 colors it gets rather fuzzy ...
#505050 & #555555 both turn #5b5b5b

1407QCAD (main)Feature RequestLowSplines: add support for knot weights, start-, end tang...Assigned
Task Description

Attached DWG/DXF files are incorrectly read by QCAD.
They contain splines drawn using ZWCAD and saved as DWG/DXF version 2000.
Above splines are polylines created with autolisp routine which converts spline to polyline, so you can see how splines should actually be drawn.

First spline is created with fit points: 2,2 4,4 6,2
Then copied and applied weight of 2 on central control point.
Then copied again and applied weight of 0.5 on central control point.

Second spline is created with fit points: 6,2 8,4 10,2 with vertical start and end tangent.
Then copied and applied fit tolerance of 1 for fit points.

Third spline is created with fit points: 10,2 12,4 14,2 with horizontal start and end tangent.

Fourth and fifth spline are correctly drawn by QCAD.

736QCAD (main)Bug ReportLowsnap tool menu is shown before specifiv tool menuAssigned
Task Description

When creating a new file, selecting the e. g. line tool at first opens the linemenu and the snap tool menu as expected. After clicking on the back button twice (going back to the main menu) and selecting the e. g. circle menu, the snap tool menu is shown instead of the circle menu. Instead the circle menu is shown after pressing the back button again.

This only happens when clicking on the back button, but with any tool menu seleected. Pressing escape to go back does not show this problem.

QCAD is running on Mac OS Mountain Lion.

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?

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.

817QCAD (main)Feature RequestLowSnap and cut all intersection in a given area tool ...Assigned
1 Task Description

As we all know - from time to time - it is a lot of work to prepare a part of a drawing for a hatch.
To get rid of one of the basic task (cutting lines along the desired hatch boundary) it would be nice to have an add-on - or what ever - what would cut ALL intersection in a drawing (or just on one layer, or just based on a selection etc.) with just a mouse click. Then it would be much faster and easier to do the selection for the hatch boundaries.
The user could decide to make it directly in his drawing or he like to duplicate the drawing to an extra layer where this function will be used ....

Clive mentioned on this:
Maybe a tool like this could be an additional ‘Snap’ selection option - select all snap intersections or select snap intersections within a boundary! then as you suggest ‘cut’ at the intersection points.

564QCAD (main)Feature RequestLowSettings organisation in levelAssigned
Task Description

As an old professional “documentation writer and user inteface designer” but IMHO, I’m not convinced that the “Application preferences” are correctly organised for ease of understanding and using them.
These settings are organised in 2 levels. Some of the first levels have their own settings (e.g. “Graphics view”) while most others don’t (e.g. “Load/save”). May I humbly ;-) suggest some consistency rules :
- no sub-level if there is only one subject
- no items on main level if there are already 1 or more sub-level(s).
For instance :
- sub-level “Default Dimension settings” under “Dimension” is the only sub-level : then move these items under main level “Dimension” and suppress the sub-level ;
- the items under “Graphics view” main level (with several sub-levels)could be in a sub-level named “General” ;
Actually, “Graphics view” main level is the only one which has both its own items and sub-levels ;-))) ?

1549QCAD (main)Feature RequestLowSeparate Coordinate Display from Drawing DimensionsAssigned
Task Description


According to the changelog for version 3.9.3 the info tools and coordinate display are tied to the current drawing dimensions. For much of my use I prefer to have the dimensions format different. The main reason is that my customers want to see the format in fractions, but when I am drawing I’d rather see the decimal format to make sure what I am drawing is accurate. So I’d really be interested in seeing a separate full configuration of the display and info coordinates.

1903QCAD (main)Feature RequestLowSaving layer settings, e.g. visibility status, associat...Assigned
Task Description

In a medium complex drawing it may be too much details to have all layers in a drawing visible at once.

Instead a number of views would be created that saves not only zoom level and position but also what layers are visible and not (as appropriate for the purpose of that particular view). This is very cumbersome (to the extent it is not really realistic) to achieve today and requires a lot of duplication of both model and layers.

The advantage of adding this is the ability to have only one model (with multiple views) and avoid duplication of work and the risk of inconsistency inherent with many copies of the model.

As a further (and natural extension to this) would be the ability to used this functionality with view-ports to be able to create (possibly many) paper-spaces from a single model. This would however require view-ports to be aware of what view they are a window into. A single change in the model would then propagate to all defined view-ports and paper-spaces.

700QCAD (main)Bug ReportLowSaved 'hatched' block loses hatching when using isometr...Assigned
Task Description

Hatched block loses hatching when using isometric projection tool:
See -http://www.qcad.org/rsforum/viewtopic.php?f=32&p=7063#p7063

When manipulating a saved hatched block with the isometric tool it loses the hatching unless the block is exploded.

Is this normal behaviour here? or a bug?

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.

355QCAD (main)Feature RequestLowRemember function for dimension OptionAssigned
Task Description

I think it would be nice to have more flexibility for Prefix etc. option (not only the drop down with a given choice) and a remember function for all those fields like postfix and tolerance.

Why Remember Function:
If I use a postfix like <>” in the postfix field I’m only able to use it for this particular dimension type at this time. If I change the type (from Horizontal to vertical or what ever) I have always to repeat my postfix. The same with tolerances.

1027QCAD (main)Feature RequestLowRectangle with a 3 point determination ...Assigned
2 Task Description

Many times I’m faced with the situation that I have to use a rectangle related to other entities. Dimensions/Angle = unknown.

We have in QCAD a rectangle tool with a two point diagonal determination but this is limited to two points and it will only work in a horizontal and vertical direction.

My feature request is based on the idea to draw a rectangle with 3 points - regardless the angle.

1. First point: start

2. second point: determination of the first side (width?) and it will also provide the angle for the rectangle

3. third point: determination second side (height?)

I’m asking for an additional new tool? No - just as an option to the existing rectangle tool ...

Task Description

When printing from the preview mode a standard Windows popup shows, letting me select the printer, number of copies and a page range. Unfortunately QCAD (or Windows) ignores the page range - it always prints all pages.

After all, print preview is not just the drawing on white, isn’t it? Everything else should stay in drawing units. Just the rulers, maybe a preference?
