DWG to PDF Transformation

[tsafarog]

Hello i am trying to get previews of DWG files (autocad drawings) into my alfresco share

I first tried with Irfanview but changed application because for some reason in the checkcommand i couldnt get the dwg to convert in pdf. So i changed applications with AcmeCadconverter which works just fine in the checkcommand

So now my tranformer looks like this:

The result in share is "Could not load pdf content"

Ok the weird thing i noticed

The target file on the debug is 0KB under tomcat/temp/afresco directory and once i get the error message in the preview that it cannot load pdf file, then another source file PDF is created from the DWG that is working just fine. Meaning that i have 3 files under tomcat/temp directory
1) RuntimeExecutableContentTransformerWorker_source_1366542181829387142.dwg (this is the source file)
2) RuntimeExecutableContentTransformerWorker_target_1118018117675185787.pdf (this one is 0KB size file)
3) RuntimeExecutableContentTransformerWorker_source_1366542181829387142.pdf (this is the correct converted dwg file but it only appears after i get the error message in the share previewer)

Another notice
The transform only occurs for newly uploaded files if the file already exists in the repository it wont try the conversion

Please advice

Kind Regards

Christos

i apoligize for the double post but i hope here to get more answers and help than the non-technical forum

Hello,

unfortunately, I can not modify a thread in this sub-forum (I am "just" a moderator from the Alfresco Community), but you should be able to close this thread yourself.

Hai tsafarog, Same thing I tried in alfresco community 4.2 e with Acme CAD converter 8.6.2 and gs 9.09,I am Unable to convert dwg file into pdf file format I am getting 0KB pdf file instead of full content file.

Please give me the solution where I am wrong ,please find the attached global.properties and transformation.xml files

Hi I've been following this post on the other thread and am asking if you can give me a small tutorial on how you have managed to achieve this. I followed every step in the other thread but I am still not getting a preview in my Alfresco Share.

It would be really helpful as it is the final task in my project.
