Hi
Is there an updated export .begc to Engrid script for Blender 2.69 available?
I can only locate ones for 2.6?
kind regards
g

[ogloth]

Did you try to run the 2.6 scripts with Blender 2.69?

[eaglemckenna]

Hi there,
yes I have tried to run the script for 2.6 entitled io_export_engrid.py
see below for terminal error messages:
gowain@gowain-Aspire-V5-122P:/usr/share/blender/scripts$ ./io_export_engrid.py
./io_export_engrid.py: line 19: bl_info: command not found
./io_export_engrid.py: line 20: name:: command not found
./io_export_engrid.py: line 21: author:: command not found
./io_export_engrid.py: line 22: syntax error near unexpected token `0,'
./io_export_engrid.py: line 22: ` "version": (0, 2),'
gowain@gowain-Aspire-V5-122P:/usr/share/blender/scripts$

is there any other modelling software that can be used that is integrated with engrid and openfoam?

hopefully I will get the blender 2.69 export sorted soon.

kind regards
g

Hi
I installed the blender 2.63a version and ran the script for blender 2.63a for engrid export within the following scripts directory and received the following error.
I am sure it is something simple I am not doing right and would be most grateful for your help. thanks

gowain@gowain-Aspire-V5-122P:~/Blender 2.63a/blender-2.63a-linux-glibc27-x86_64/2.63/scripts$ ./io_export_engrid.py

./io_export_engrid.py: line 22: syntax error near unexpected token `1,'
./io_export_engrid.py: line 22: `    "version": (1, 1),'

then i tried python command and it states there is no bpy module:

gowain@gowain-Aspire-V5-122P:~/Blender 2.63a/blender-2.63a-linux-glibc27-x86_64/2.63/scripts$ python io_export_engrid.py

apologies once again

Greetings to all!

@Gowain: Uhm... you're not meant to run the scripts from the command line. You're meant to install them in Blender and then use them in Blender:

• Instructions on how to install add-ons in Blender: http://wiki.blender.org/index.php/Do...Python/Add-Ons
• Example of how to use them in Blender: https://github.com/enGits/engrid/wik...ting_the_Model - see the description in the section "Exporting the Model". That page is an old tutorial on how to use Blender for enGrid, but some information can still be adapted to the current Blender versions.

Best regards,
Bruno

Hello,

I just tried the scripts with Blender 2.7 and it worked without problem, so I assume that 2.69 will be fine too.

Regards,
Oliver

[eaglemckenna]

Thanks so much guys
It's sorted now.

I changed the blender export script as the one posted above gives me following errors:

mesh object has no attribute faces

I changed ti according to http://blenderartists.org/forum/show...ute-Faces-quot

Hello,

I try to use the export script 2.63a io_export_engrid.py version from sourceforge with Blender 2.74 on OS X. As intended I put the script in the Contents/Resources/2.74/scripts folder. However in the File/export menu I can't see any export to enGrid option.
Has anyone experienced the same. Is it generally just supposed to work with the Linux version of Blender?

[KateEisenhower]

Okay, I got it. You have to put the the import and export script inside the Contents/Resources/2.74/scripts/addons folder. After that go to File/User Preferences in blender, search for the scripta and activate them.

[Davidkep]

Hi guys

i dont have much info about scripting, I have this script for zbrush import/export, its for windows and Im using Mac osx, i tried to use it on Mac but apparently only "Obj out"export works fine but the "Obj in"import Dosent work, can anyone help me to rewrite this script for Mac ? i tried it on windows and it worked fine.btw i tried to fix it by changing the location of the folder to match Mac path

Copy the 2 files into your Zplusg64, and the two button will show on your right button on you zbrush screen.

Thanks in advance

[SimonStar]

Hello,

is there somewhere a guide how to put a script into blender? Or how did you do that exactly?

I'm still in the beginning with trying to understad OpenFoam and the meshinge, so I guess I need mone help.

Tanks for any help.
