 1993 QCAD (main)Bug ReportLow Draw > Insert Bitmap: relative zero point not set Closed
Task Description

If I insert a bitmap the relative zero point (RZ) isn’t set at all. It will be set at the mouse position in the moment when I terminate the tool.

This leads among other things that I can’t use the Alt key for ortho mode or other tools for restrictions.

 2002 QCAD (main)Bug ReportLow Draw > Viewport > Add Viewport: Hatch is offset incorre ...Closed
Task Description

When a hatch have been offset in the Model then it appears incorrectly when rendered in a Viewport. It seems that in Viewports the hatch Origin value is not taken into consideration. This means that when adjusting a hatch in the Model to look correct (align along a line for example). This alignment is off in the Viewport.

See screenshots and attached test dxf file in this thread on the forum: https://qcad.org/rsforum/viewtopic.php?f=33&t=6742

Edit: After looking more into this issue is seems it is the Viewport’s position that is ignored when transforming the pattern into Viewport space. See the following gif:


Above it can be seen that that pattern is always rendered in ‘worldspace’ since the pattern is static (the pattern is not moved when the viewport is moved around)

I like the new shape tool “Star”. Comes at the right time ;-)

Would be nice if we could get the same options like all other shape tools: “Create Polyline” and “Fill”.

2014QCAD (main)Bug ReportLowFocus on Options Toolbar failsAssigned
Task Description

Scenario: e.g. Tools Move/Copy and Rotate switched to “use without dialog.

Launch within a drawing Move/Copy, use the Keyboard keys CTRL + Space to focus on the Option Bar - the field for Numbers is Highlighted and I can change it. Further navigation with keys on the keyboard depends on remembered option (copy yes/no etc what make a navigation possible or not. It looks like the navigation with the Arrow keys is focused on the canvas and sooner or later the courser will jump to the Command Line or Property editor. Same behavior with the Rotation tool.

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.

2031QCAD (main)Bug ReportLowOrdinate Dimensions don't act as expectedAssigned
Task Description

Hi Andrew

I wasn’t sure if this was a bug or feature request, when I’m drawing part sets that only change in lengths I dimension them
to save time then I stretch and save as whatever filename... I was surprised when Qcad reacted the way it did when stretching ordinate
dimensions on a part, the 1st thing I did was window select over the dimensions which didn’t work ( this is the typical way for
stretching ordinate dimensions in AutoCAD,IntelliCad,Draftsight etc )... anyway Husky and I had a fairly long debate and he told me
I had to select the object and only parts of the ordinate dimensions which when stretched leaves a bit of tidying up to do..
Please let me know if I’m going about this the wrong way.. do i really have to do multiple stretches and move all the jogged dimensions?

See Topic https://www.qcad.org/rsforum/viewtopic.php?f=32&t=6901&start=15 It started off with negative values for ordinate dimensions then turned into problems stretching ordinate dimensions..
I also posted dropbox links to quite a few videos..

Attached is a zip file containing some screenshots plus the original dxf file..

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.

In my example I can’t draw a circle with circletangent2 if the defining point is on one of the defining tangents. The tangency is lost when I try to do this.

 2042 QCAD (main)Bug ReportLow linetangent can't draw a tangent to arc through a point ...Closed
Task Description

Very often I need to draw a tangent line through a point on the arc or circle. Currently I solve this by drawing the perpendicular in that point and then the perpendicular to that perpendicular. As this problem is solvable I set the severity to “Low”.

But I think linetangent should be able to draw such tangents. And I think this tool should firstly ask for arc or circle and only then for a point. Currently linetangent firstly asks for a point.

2047QCAD (main)Bug ReportLowQCAD quits when inserting a library item, Ubuntu 19.10 ...Assigned
Task Description

QCAD quits when trying to insert a library item (PC_1kW.dxf) from the library browser. Both by dragging it or clicking on insert.
Joined a copy of the terminal and dmesg (Linux) and what I found on the windows logs.

- Tested with other libraries elements of the same origin with the same result.
- The file opens normally in QCAD. When you create a block from it, you can re-insert it and it works as expected, try with PC_1kWblock.dxf...
- If you re-create a library item from the file with another name it fails also to insert.
- Tested with a new empty file or with a file containing same blocks...

Now the strange part:

-On a brand new HP Zbook 14u G6 it works flawlessly on Windows but fails on Linux... That was the first computer I tried (with Windows) when I decided that it will replace Draftsight... I was lucky...
-On a 4 years old Lenovo Yoga 14 it fails both on Linux & Windows... This computer has only 8Gb of RAM, but dedicated graphics...
-On a customer’s HP Pavillon 17’’ it fails... He bought a licence & Book of QCAD because of me...
-On my Dell 7720 it fails both on Windows and Linux. This workstation has everything to run any CAD software (64Gb RAM, Xeon 1535M v6, Quadro P5000)
-Reinstallation of the software doesn’t solve the problem. 2 independent sources tested (my download and my customer’s download)

These blocks have a lot of attributes on different layers, needed for the intended usage. I’m developping a script to extract them to a CSV file based on a template file... As on Draftsight.

Looks a lot like  FS#1938 ... But now you have files to test...

I made further testings and this bug is definitely related to the fact that the attributes definitions are on different layers...

If the layer definition exists before the library items is inserted, it works as expected.

If one layer existing in the item definition is missing from the layer list before the item is inserted it fails.

If you create a block from an instance of the library item, and create a new library item with the block, then it can be inserted without problems and the layers are created... But you must explode it first to access the attributes which is not the idea behind the block attributes that should be editable when a block with attributes is inserted.

So at the moment the only way to work is to start with a template document with all the possible layers on which attributes definitions are defined...

Can’t go further in debugging as block attributes are one of the feature of the ‘professional’ version I paid for and are not open source...

Ready and willing to sign a NDA to get access to the sources and make this work if nobody else takes care of this.

2048QCAD (main)Bug ReportVery LowMove / Copy to current layer fails when reference point...Assigned
Task Description

QCAD 3.24.2 / macOS x86_64 10.14.6

Starting with empty doc:
1. Draw any object (e.g. a rectangle) on layer 0.
2. Create new layer (”1”) with color, say yellow.
3. Select new layer
4. Select new object
5. Modify → Move / Copy
6. Click reference point
7. Click target point same as reference point
8. In “Move / Copy Options” dialog, select “Delete Original” and check “Use current layer and attributes.” Click OK.

The moved object stays on the layer it was previously on. Using “Move / Copy” as a quick way to move a selection between layers is not useful even though it appears to be the recommended way in a Google search.

Note: if “Keep Original” is selected instead, the copied object is placed on the current layer and the original object remains on its layer, as expected.

Note: if the target point is different from the reference point, the moved object is placed on the current layer as expected.

There are other workarounds too, cut / paste with “To current layer” checked seems to work, as does chaging the layer in the Properties Editor.

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.

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!
