Dear Fredo6,
I have just updated to SU2013 from SU8 and tried to re-install RoundCorner (v2.3a)
I had it working fine whist in SU8 but cannot get it to work on 2013?
I have updated to the latest Libfredo6 4.9 plugin on SU2013 and it is showing up inside SU2013, however, I cannot seem to be able to open up the the RoundCorner box from Extensions nor can see it anywhere in the tools palettes? Please advise. Thanks in advance.
I am on mac os X (10.8.4)
EDIT - I have found a way to fix this. Change the .zip file downloaded from here and change the parameter to .rbz and then copy/place the file to sketchup plugin folder. Open sketchup and from Preference / Extensions / Install extension - locate .rbz file from plugin folder and woala!! RoundCorner tick box should appear which means installed! From there, go to View/ tool palettes/ RoundCorner to open up tool bar.
Not sure if this is the proper way to install but worked for me on MAC.
Thanks Fredo for this great and useful plugin.
Cheers!!
