Is any trial version of QCAD 3 Beta 3 now to try?

hungerburg, may I ask you to make a simple script wich will use maximum of theese commands to make a drawind, and save the drawing in script locate folder or in any other filder. I see you very good linux and QCAD user.

[alf2006x]

I forgot that the script should be saved in both DWG and DPF formats.

[alf2006x]

hungerburg, andrew please help me. I understand, that this is maybe my arrogance to ask you write some scripts. But I begin to get confused. Almost get lost.

If you can - just write the script, wich draws two lines
line (0,0) - (50,50)
line (50,50) - (0,100)

and makes a chamfer (or fillet) between this lines
and save this drawing as pdf anywhere.

Thanks in advance.

Rather than posting large pieces of code to this forum, we are continuously updating our API documentation and howtos.

Here's a howto about creating a drawing document in a command line application and adding three lines that form a triangle. The drawing is also saved to a DXF file:

More will follow...

I tried to run script from link, byt something is wrong with it (please look at my log below).
Then I comment the last row: di.exportFile("example.dxf", "DXF 2000");
Then no any errors arrived.
But I can't get result file.

hello Alf,

where did you look for the file "example.dxf"? I found it in /opt/qcad3, because this is where I installed qcad3. (That's called the "working directory" of the application. Unfortunately this is different from the "current directory", the one where I issue the command…)

You will not find it though, if you comment the line that saves the drawing to file Maybe make the line read "di.exportFile("/home/alf/example.dxf", "DXF 2000");" to have it created in your home directory, if you go by the name "alf" on your system…

[andrew]

alf2006x: output looks good and normal. Nothing to worry about. I don't see any errors and your file should be perfectly fine.

[alf2006x]

hello, hungerburg

that is fantastic! i've found my example.dxf file in qcad directory! that wasn't , that was log.

but now it dont work again.
first it writes an error:
alf3@ubuntu:~/Downloads/qcad-3.0.0-beta3-trial-linux$ time DISPLAY="" ./qcad-trial -no-gui -autostart '/home/alf3/Downloads/example.js'

then i goes to site again, copy text of script and make my new file example.js
but now it writes this:

i cant understand anything . what was happend?

[hungerburg]

Yes, that is really strange. Things should not fail inconsistently.

So you did modify example.js and it stopped working? You then replaced the contents of example.js with the text from the howto? and it still doesnt work.

Perhaps you changed something else? If you cannot remember, just start from scratch. Unpack the qcad archive again. Try with different arguments. What widget will be created, if you allow that? Etc.

As a developer, you have to be very careful in what you are doing. Best practice was, to note every move you make.

[andrew]

alf2006x: one common cause of this, is that an exception occurs (syntax error, typo, etc) and QCAD wants to show the debugger but cannot since we are using the -no-gui switch. Try to run the script without -no-gui and see if the debugger pops up. Once your script works, try with -no-gui again.

[hungerburg]

Alf, previous post was general advise. This time I suggest: compare the contents of example.js with the text of the howto. I am sure you will find that they dont match.

[andrew]

I am sure you will find that they dont match.

Yes, I also think something went wrong with the contents of that file. At least I am unable to reproduce the problem here with example.js

[alf2006x]

yes, that was my fault.
in first string of my script comments was written with only one slash. like this:
"/ init application name:"


and what about converting my drawing in pdf? i dont found any information about this on API documentation and howtos page. i used "search"
