Post all kind of layout issues for the book “CAD Instruction” here, e.g. overlapping text.

The numbers in the book don’t match with the bookmarks numbers in the PDF as shown in Acrobat Reader.

Library - Architecture is showing only four (4) symbols:
“ffl, north, uparrow and winv”.
Is this correct?

Thanks in advance

QCad Book

Would be nice to have the index linked (like Bookmarks, Hyperlinks, Jump marks) with the regarding chapter.

So that I just can click in the index what I’m looking for and it jumps directly to the correct chapter.

I have the book dating about a year back, with the following metadata (no other version information in there):

Producer:       FPDF 1.7
CreationDate:   Fri Aug 24 15:10:36 2012

I believe there is a slight error in the Orthographic Projections hands-on (it may not be there in current versions of the book, but since my download timeframe is long over, I can not check that – should that be the case, sorry for the noise).

On page 219, step 1 of the exercise (drawing the front view), it is said

Set the first corner of the rectangle at the origin of the drawing (1)
and the other corner at 30,20 (2).

On pages 225-226, steps 7 and 8, drawing a 45-degree auxiliary line for the right-side view, it is said

Set the position of the line at the origin of the drawing (coordinate 0/0).

0/0 is the “bottom left” corner of the top view. The correct coordinates for the auxiliary line’s position are 0/30, the “bottom left” corner of the front view.

(I had not realized the bug tracker had a Book category as well – hence this is a duplicate of an e-mail report I have sent to [email protected])

In the “Drawing a Shape Using Absolute Polar Coordinates” hands-on, step 3, there are two toolbar pictures, each with a caption. The pictures don’t match the captions; ie. the pictures should be swapped.

When I run bbox with the attached file I get inconsistent results if I run it 6 or 10 times.

Sometimes the size is 448979.2349223149/310815.2964427199 (it thinks that there is an object at 0,0)
sometimes it is 338.0789223148604/302.31644271989353 (this is what I think is correct)

Andrew,
While enhancing DrawFromCSV: Forum Link.
I had a peek at the new command line tool: dwg2csv

I would never come up with 115 columns.
That wouldn’t be efficient to generate entities from.
Although this way it is very complete and one could use specific lists to filter.
One downside is that the ‘-list’ switch return is far too vast for the windows command line.

Remarked that:
Only the first alphabetically custom property is listed under:
QCAD:Line & QCAD:Reference (columns 114-115).
And that the last encountered is persistent for all entities that follows.

Maybe this originates from a multiple entity selection ...
... what also retains the last encountered custom properties in the property editor.
Should I add a seperate task for that?

Also had an exception thrown:
Debug: dropped global XDATA (no res buf): “ViewportCenter”.
Discarted that as this very basic test drawing hasn’t even a Viewport.

Regards,
CVH

Change the user manual directory / file names from ‘simpletextviewer’ to
‘qcad_user_manual’ and adjust the sources accordingly that the manual can be shown
in the help menu.

We can simply drop the contents of the manual that is checked in and replace
it with a simple note “No manual is available yet for this technology preview of QCAD 3”

Create some CSS to display the user manual in a professional way, similar to web site.

Rename everything from “RSFramework” to “QCAD Application Framework” (qcad_application_framework.pro / dox / doxyfile ...).

Add header with copyright / link to homepage.

Structure of documentation:

• Entry (main) page
  • API (links to API doc for modules):
    • math
    • core
    • gui
    • ...
  • ECMAScript Developers (links to intros and examples):
    • ECMAScript introduction
    • ECMAScript module

Please explain the possibilities of the “Library Browser” I’m not able to make a new entry (Drawing Sheets)

Layer ‘0’ has some special function. E.g. it can not be deleted, it will contain the data of undeleted layers.

I recommend adding some explanations: Explain the function of Layer ‘0’ as third paragraph in chapter 12 of the manual. Further it should be recommended to never use this layer for drawing.

By the way: I consider this to be better than no layer undelete. BUT: is there really not way for a true layer undelete...

I just downloaded QCAD and bought the doc that goes with it. Lo and behold, I find that I cannot search the doc in Preview (Acrorbat Reader too!)! So I paid extra for doc that might be argued should come with a product (although its hard to complain about the price) and then I cannot even search it electronically? There is just everything wrong with that in the year 2014! Please fix as it is extremely inefficient and time consuming to not have electronic search capability.

• Draw a circle
• B2
• Make sure “Remove segment” is ticked
• Select circle, then select two points to break out in between

Expected:

• Segment gets removed (not really, but read on)

Actual:

• Segment does not get removed, but circle is indeed broken into two arcs

Same for an ellipse.

I can see that by selecting two points on a closed circular shape it’s nigh impossible to tell which segment the user actually wants to remove :)

The documentation doesn’t mention this corner case. For clarity, a note detailing this effect a bit should be added to the docs.

On a slightly related note, I do not see why the feature couldn’t work on Polyline objects as well (with the same corner case restriction if it’s a closed polyline).

Very useful feature btw, thanks for it.

I can’t find any documentation (Reference Manual / Book) about the possibility to change the “corner” transition shape for Spline’s (Control Points) with multiple mouse clicks.
1, 2 or 3 clicks = smooth to sharp corner.

... describes basically the “Paste” tool and not the “Paste along Entity” tool.

Now I try the third time to post this .... .... deleted by “wrong token”???????

Regarding to the online tutorial:

quote:
Opening a CXF Font for Editing

To load an existing CXF font file in QCAD to view and edit its glyphs, simply use the menu File > Open and choose the format filter “CXF Font Files (*.cxf)”. Then choose the font file you want to open. The fonts that come with QCAD are stored in directory “fonts” of your QCAD installation.

quote end

Editing the cxf font in the original QCAD font folder will lead to a error message triggered by the Autosave function:

File access error: “C:/Program Files/qcad-3.22.1-pro-win64/fonts\~~Husky_test_font.dxf”. Access is denied.
[15:34:58] Autosave failed: C:\Program Files\qcad-3.22.1-pro-win64\fonts\~Husky_test_font.dxf

Note: Windows will not save anything in a system folder and the process is terminated by windows.

Solution: Move the cxf font for editing from the QCAD folder to a unprotected folder like Documents/drawings.
After editing is done move it back to the QCAD font folder.

explicit drawing order of objects (such as sending hatch to back and bringing text to front) not respected when export to pdf used, the order of overlapping objects seems to use the order in which they were added to the drawing

this causes problems if we try to export a dxf to pdf and the hatching was drawn after some of the text

dwg2pdf shows error under Windows systems:
Fatal: QWidget: Cannot create a QWidget when no GUI is being used

Autofit (-a) has no effect when converting a block or layout block (other than Model_Space).

The original file is A5.dwg. I’m using QCAD professional 3.23.0. A5.pdf is converted by command line tool dwg2pdf.
I found the drawing problem in it. See the attachment file problem.png.

As you see, I write down 3 bugs in problem.png.

1. bug 1. The position of ‘green 90’ is wrong.
2. bug 2. The line width is too large. You can see dot in A5.dwg, but a line in A5.pdf.
3. bug 3. The ‘green 42’ is missing.

Thank you very much for your help!

Hello, I found a bug.

See the problem2.png.

Original file: 004.dwg.
After converting pdf by dwg2pdf. The file is 004.pdf. I can’t find any drawings. I scale the pdf reader to 6400%.
But the drawings are still too small.

This is my using command: .\dwg2pdf.bat -f -a -recompute-dim -ltscale=1 path

Morning, I found a bug.
Andrew, Thank you very much.

As you see, there are 2 bugs:

1. There are 4 tabs in the original file. But dwg2pdf can only convert one tab to pdf.
2. After converting, the right column drawing is missing.

Relative to https://www.ribbonsoft.com/bugtracker/index.php?do=details&task_id=1965

I suggest that if dwg2pdf have an new options that can convert all the blocks to pdf.
Now, I need to know all the block names before converting.

But if I put qcad on server, the computer won’t know how many blocks in the dwg and their names.

For examples:

There are 4 blocks in dwg.block1, block2, block3, block4

Command line: ./dwg2pdf -block-all path

Result: block1.pdf block2.pdf block3.pdf block4.pdf

Good afternoon! I have a suggestion.

Relative to https://www.ribbonsoft.com/bugtracker/index.php?do=details&task_id=1964

I did not find option -max-lineweight.
