Hey Mike, I know your post it's quite old, but hope u get and email from my reply.
Sorry, but the link for the export script from Blender to Engrid is broken. There is nothin hanging on that url.
Could you tell us where can we get the scripts now?

Thanks

Another Mike

Hi!

I'm not Mike, but maybe I can help. :)
I think they can be found in the directory, to which you installed enGrid. There is a directory enGrid/src/scripts. I hope I remember rightly.

greetings

what i have there is this ->

none seems to be the one, right?

I actually found it, and put it in another post of the forum, here it is ->
export script:
http://dl.dropbox.com/u/19241820/enGrid/engrid_export.py

might need to remove line numbers in the file first

Hi,
as a new user of enGrid, I am having the same problem - but in Windows. I've copied the export_engrid.py script (line numbers removed) into the Programs\blender\..\scripts folder, but I don't see the option in the export menu of blender.
Is there something I'm missing?
Thanks

Greetings to all,

@k_xyz: Did you see this section of one of the tutorials for enGrid 1.2: http://engits.eu/wiki/index.php/Tutorials/Version1.2/Unstructured_Grids_for_OpenFOAM_With_Blender_and_enGrid#Unstructured_Meshing_with_Blender_and_enGrid

Also, did you restart Blender after copying the script to that folder?

By the way, which Blender version are you using?

Best regards,
Bruno

Hey, Miguelfg, what do you mean "might need to remove line numbers in the file first "?
English isn't my native language, might therefore i don't understand it.
My blender don't export to engrid, may it be because i use 1.3 version?
use fedora 14-32
Thanks

Dear All,

I've taken the py script, removed the line numbers, and dropped the script into the
"C:\Program Files\Blender Foundation\Blender\2.60\scripts\" ...

using Blender 2.6, I unfortunately see whether an import nor an export option... some things changed though in 2.6 - are there new instructions?

Mike

Hi,

with Blender 2.6 the whole scripting interface has changed. Hence we don't have any scripts for 2.6 yet.

If somebody has scripting experience with Blender 2.6, we would be more than happy about some help porting the scripts. I had a quick look and so far I managed to make our scripts show up in the add-on list; they cannot be enabled or used, however.

As an immediate work-around, I would recommend to use Blender 2.49b. I just checked and I seem to be able to open models from 2.49b in Blender 2.6 without problem. Thus you would not lose your work, once the scripts start working in 2.6.

Cheers,
Oliver

Ok, I will try Blender 2.49.
Please keep us up to date when the 2.6 scripts are released - they are very valuable!

Mike

Hello, rewrote the script simple addons export engrid for blender 2.60 (io_export_engrid)

Hi,

Thanks for the effort! :-)

I do not understand your question, however? The script you provided works, i.e. the file format is correct in your script. The only thing left to fix is that the names don't come across correctly; they show up as Plane... instead of the name that had been given to the object in Blender. I'll have a look at that later.

Is it okay to include the script in the distribution? If yes, do you want your credits to be shown in the script? In which case you need to provide them ;-)

(just send me an email if you want to at: ogloth[at]engits.com).

Cheers,
Oliver

I have updated the script slightly. It should now, hopefully, behave in the same way that the old script did (i.e. names and transformation).

The script can be found here: http://db.tt/HUJynYkQ

ok

Hi,
I have modified the script to fix this bug and also added more function.
Add custom properties:
Rotate 90 degrees around X to convert to y-up,
Transform the Vertexcoordinates into Worldspace,
Applies the Modifiers.

Hi,

I have the same problem. I am using engrid 1.2, blender 2.49, but after I copy the export script (both the old one and the one updated by Oliver)　into the folder, and restart blender, I can't find the option of engrid in export.

Is there anything else that I need to do?

Thank you!

which version (blender 2.49 or 2.59) of the script you copy?
in which folder you copy the script?

For linux, I copy the script for blender 2.49 in folder /usr/share/blender/scripts.
It works.

old script for blender 2.49 http://blender-3d.ru/forum/index.php/topic,126.msg3865.html#msg3865

Hi,

Thank you for the reply.

I am using blender2.49. Is the script the last attachment? I put it in /usr/share/blender/scripts, restarted blender and rebooted my computer, but there is still no export -> engrid in blender. That is so wired. Do I need do something else?

Thank you.

Best, Hang

имхо,
for linux, check permission ...
show the output:

ls -l /usr/share/blender/scripts/e*



... and show
cat /usr/share/blender/scripts/engrid_export.py

Hi,

ls -l /usr/share/blender/scripts/e*
results in output like below

-rw-r--r-- 1 root root 2898 Nov 12 14:39 /usr/share/blender/scripts/engrid_export.py

and other .py files.

cat /usr/share/blender/scripts/engrid_export.py gives

Sorry that the copied text looks messy.

Thank you!

:(

but other way:
in Blender Text Editor -> Alt-O (select /usr/share/blender/scripts/engrid_export.py) -> Alt-P (run this script)

Great!

I tried to run the script manually, it worked!

Thank you！

While I'm back for a short while, here's a tip for easier imports into blender (for GNU/Linux users at least):
import_engrid.sh:
==========
#!/bin/bash
blender -P $HOME/.blender/scripts/engrid_import.py -- "$@"
==========
(Adapt the script path as needed. Using an alias, or directly running the command are also options of course.)

Then you can just run this to open one or more engrid files in Blender directly:
$ import_engrid.sh FILE1 FILE2 ...

Works for Blender v2.49b. Not sure about v2.5+.

I might have a look at direct file association in filebrowsers at some point as well. Unless this has already been done and I don't know about it yet. :)
