Right, I think my exe file is not up to date. Fine now though.
BTW, I modified your plugin Compute Walls Surface for my purpose and just for it (being messy of course), still I post it here if anyone bother to test or use it.
don't know how to attach a file


//version 25 Dec 2014

thank you, I think I did a wrong thing to run the Sweethome3d.exe instead of its Jar version. Will try again.

I followed exactly the Plugin development guide and created VolumePlugin.jar in plugin folder.
However when I opened the main Sweethome3d, it stays the start up picture forever.
I tried changing JRE package (I have v6, v7 on my Win7) but no help.
Any ideas? thanks
