316QCAD (main)Feature RequestLowBlocks list and selected blockAssigned
1 Task Description

Wouldn’t it be nice, if selecting a block in model view would somehow highlight (just like clicking a block in the list does) the selected block in the “Block List” window?

(Feature request sounds a little harsh, enhancement proposal would seem more apt.)

 748 QCAD (main)Feature RequestLow Blocks ... Closed
Task Description

It would be nice ...

- to be able to use " and / in Block names what is really helpful in the Inch and Fraction world ... ;-)

- the ability to overwrite an existing Block what is often much easier/faster than editing a Block ;-)

- After selecting a Block you get the info of the Block name in the Property Editor (Geometry / Referenced Block).
If I need to edit this Block I have to go to the Block List - have to search for this name because it is not marked .... and of course it is a long long list.
It would be nice to have a “Edit this Block” Button in the Property Editor / Geometry / Referenced Block dialog ... ;-)

Task Description

I would appreciate an option for the library Browser that gives me the possibility to decide by my self to use the current (same name) layer in my drawing or overwrite it with the existing layers in the library item.

Imagine the possibility’s of this feature .... ;-)

 555 QCAD (main)Feature RequestLow Blöcke zählen .... Closed
Task Description

Eine Zählfunktion die erfasst wie oft ein Block in einer Zeichnung vorhanden ist.

Hintergrund ist das es damit eine Unterstützung gäbe die das erstellen von Stücklisten etc. erleichtert würde.

Die Anzahl der Blöcke könnte z.B in der Block List eingeblendet werden wie z.B.: “Schraube M6x40 (17x)” oder auch in einer extra Text Liste.
Zudem könnten so auch nicht (oder nicht mehr) benutze Blöcke ermittelt werden wie z.B. “Schraube M6x20 (0x)” welche dann aus der Zeichnung entfernt werden könnten.

Task Description

Blöcke aus dem Editiermodus direkt in der Library speichern zu können wäre eine erheblicher Arbeitsersparnis.

Wenn ich persönlich einen Block in einer Zeichnung erstelle überlege ich mir natürlich gleich ob ich diesen nicht auch in anderen Zeichnungen verwenden könnte. Somit erhalte ich leicht eine Umfangreiche Library die mein Leben leichter macht .... ;-)

 1030 QCAD (main)Bug ReportLow Block->Create Library Item Issue Closed
Task Description

I create a number of library items to create parts assemblies..

I will build a component in a drawing that has other components in its own layer then isolate the component and only select it. I then use Block→Create Library Item to create a component, set it origin and save the item.. When I open the item, there apears to be a set of duplicate lines generated. I have to select all the components and do a detect duplicates then delete them before doing anything else with the drawing.. I found this issue by trying to create a cutaway view then adding a crosshatch. The crosshatch tool does not like lines on top of lines..

The characters in Portuguese such as “ç é â ... etc ...” are replaced by codes starting with version 3.16.x
Files created with versions of QCAD 3.15.x whose characters were correct in the Properties List when opened by QCAD 3.15.x appear in this strange way when opened in versions 3.16.x.
However, in the screen and in the extraction of the list of attributes the characters are correct.
Apparently the error only occurs in texts on the Block Properties List and Attributes.
However, you can use correctly the characters in a file created from version 3.16.x

Exemplo: “dormitory’ in portuguese is “dormitório” it’s appear like “DORMIT\U+00d3RIO” when file is opened on QCAD 3.16.x

1 Task Description

I just updated my QCAD to (3.26.2) version and lost the hability to edit block attributes of my sheet or in any other block.

I tried to save as the drawing and the problem persists.

When I open the block, the attribute is there and is all set in the Specific Properties, but when I exit to the Model Space to edit the Attribute text, the created attributes don’t appear on Specific Properties tab.

The use of block attributes in sheets, balloon or any block that contains text is very necessary.

1 Task Description

1) Open the attached dxf file
2) Right click on “vne_vent_odvod_ec_3f” block in Block list and select Copy block
3) Choose name
4) Insert reference of this Copy block to the modelspace
5) Save the file
6) Close and reopen the file

RESULT: Attributes of block references included in the original block are missing in the copied block.
Immediately after insertion of the copied block I can see in the property editor, that block reference attributes are not “conected” to the block reference, but they are still visible. They disappear when the file is reopen.

Alternative way I use to copy this kind of blocks without error: Open block I want to copy, Select all entities, reference copy of them, paste to modelspace, select them in modelspace and choose create block.

 580 QCAD (main)Bug ReportMedium Black color reverted to white color on each close Closed
Task Description


When I started Q3, I selected a White background in the initial dialog window. I opened a copy of a good Q2 file and saw that ALL entities with Q2 Black/White color where forced to be White. Andrew explains this as a mean to avoid unreadable items against the background colors. Remember I selected White as background ? I guess Black/White entities could be better kept as Black ?

Following Andrew’s advice, in Application Preferences =⇒ Graphics View, I unchecked the Auto correct black and white colors check box. The background settings is white. OK.

I went through a process of changing the White color for several layers to Black. I also had to change the color codes for the hatch areas. For instance, the hatch area layer “055_F_Murs” has “14-76-255 / 255-197-179” values in Q2. Why these values are auto corrected to “30-128-255 / 255-191-127” ?

After these changes, I saved the file, closed Q3 and opened the file again.

Catastrophique ! All “Black/White” layers were back to Black and the hatch colors were back to the “auto corrected” values.

Changing the background color to black then white seemed to solve the problem : the layers kept the Black color. Actually it was just an illusion.

Yesterday too much confident, I spent the whole day, modifying layers to Black, adding new layers also Black or custom color, checking the line weight (replacing the “default” (?) value of 0.25 mm with my preferred default value of 0,00 mm, I’ve posted on the forum about this) and so on. I saved the file, closed it.
To-day, nearly all layers have lost their colors :
- Black ones are again White,
- custom color are “auto corrected” as above for “055_F_Murs”,
- only the standard non Black/White colors are preserved, like Blue, Magenta etc.

At this point, I can’t continue using QCAD 3 with enough reliability as my color settings are always lost. This is why I qualify this bug as CRITICAL.
I don’t want to use a Black background or a Light Blue one. Why do you think all old “green on black VDU” were replaced with “black/color on white” displays, to begin by Apple ?

NB I already reported this but can’t find it in the list (maybe because I forgot to enter a summary ? No warning, happily I had a copy with Notepad), sorry for the duplicate.

1080QCAD (main)Feature RequestLowBitmap export: calculate size based on bounding box inc...Assigned
Task Description

I have created a drawing, where the CENTERS of the most outer lines have a distance of 3.06mm in both X and Y.
The line weight of these outer lines is 0.6mm, so the whole image is 3.06mm + 2* 0.6mm/2 = 3.12mm wide and long (center to center plus half of the line weight on every side).
Additionally in the export there is a frame around the image, making it 3.12 + 2*frame.
The export function however calculates 3.06mm when setting the resolution to 1000Pix/cm, so it does not include the line weights and the outer frame.

2242QCAD (main)SuggestionLowBill of MaterialsAssigned
1 Task Description

It would be a very interesting feature to add to future versions.

I also use AutoCAD Mechanical 2012 and the BOM is synced with every balloon on the drawing. Making it easy to edit.

The core BOM accepts formula fields and we can easily calculate the mass of a part, with some Ifs and math.

The BOM that is shown in the actual drawing is more simplistic, and has just Part number, Quantity, Mass and the Description. But it’s related to the “core BOM”.

It’s a very interesting thing! It would be great on QCad.
