LibFredo6 is a companion Library required by all my scripts.

LibFredo6 is a shared library used by some of my plugins. It is NOT a standalone plugin. Plugins currently using LibFredo6 are:

You need to install it and respect the versions required by the Plugins, the higher, the better. The current version level of LibFredo6 is 7.7. I maintain backward compatibility so that plugins requiring an older version of LibFredo6 should work with a newer version.

LibFredo6, like my other plugins, is hosted on Sketchucation. Sketchucation is a Community site entirely dedicated to Sketchup. It includes an ExtensionStore of 800+ plugins, as well as a quite rich Discussion Forum about Sketchup and a Gallery. Registering on Sketchucation is FREE.

IF YOU ARE NOT FAMILIAR WITH LIBFREDO6 INSTALLATION OR WITH SKETCHUCATION, it is advised to watch the video "LibFredo6 Installation" at the top of this page.

You can find more information on the Home Page for LibFredo6 on Sketchucation.

IMPORTANT: if you just install LibFredo6 without any of the plugins above, you will see no new toolbar in Sketchup but a menu entry "LibFredo6 Settings.." in the Window menu of Sketchup.

Appreciate letting us use this plugin thank you! Would definitely recommend to someone who's considering using it and hasn't jumped on board yet. We use SketchUp for our law firm and it helps us streamline what we need to show them out here in Sacramento and it works very well with this plugin.

I tried installing using both Preferences and Sketchucation Extension Manager, with this error I cannot install any of the Fredo tools. How do I correct this?

t works fine when interesting a curved surface with a flat plane but two curved surfaces will not give anything. Tried ungrouping exploding everything and selecting just the intersection zone no luck

what am I doing wrong ? Thanks in advance anyone !

Super helpful thank you. Highly recommend this to anyone checking this page out and still undecided. We use SketchUp when educating customers in our residential bird prevention business in Arizona, and it's working great with this plugin.

excelente todas! muchas gracias kapo!

I downloaded and installed LibFredo6, then went to SketchUCation and registered but I cant download anything. Tried to download RoundCorner but nothing happened...and its not my computer either because when I pressed the "Donate" button it took me to the correct page (of course), when I pressed the "More Info" button, that also worked. The "Download" button, however yielded NO results. What gives?...You really need to simplify this thing

Sketchucation have had some server problems and have been working on it. (I am not involved) Maybe try again now. If you clear your browser cache and try again it could help as it helped me with a different issue.

Hi Freedo
Having same problem about the toolbar. The plugin is correctly loaded and i can see the toolbar , but when i try to use it nothing happens.
For a couple of days the plugin worked like a charm, and i was able to see the prompt toolbar with all features on. While was working with SU suddenly it crashed, and once i restarted the program , roundcornes started to not work properly.
I 've disabled any other plugin i have, trying to exlude problems may occurr .
Pls any suggest would be appreciated. thx for any answer

Hey Dom,

I found this page on SketchUcation There is a link to install "RoundCorner_v3.1b.rbz" you need to have "Fredo6_!LibFredo6 - v7.4c - 16 Jan 17.rbz" loaded prior to loading "RoundCorner_v3.1b.rbz". This will add the toolbar to the menu tab.

Follow the below link for round corner:

Follow the below link for instructions:

Hy Th D.

No I haven't and would really like to have it. I was using it for the last few years often but suddenly in SU 2017 it seems there is no update available. I get the same signature outdated message.

I can not seem to find an updated version of ROUND CORNERS for SU 2017. Anybody can help?

Many thanks!

The current version works, the signature-message does not affect the plugin, it's just a message.

Hey. Did you ever get to find the updated version? I get signature outdated, plugin not working. Never used it before, looks like a great plugin..

not working in sketchup 2017

thanks for helping
