So if I understood you well I should work in a larger scale (x100, for instance) and only in the final step reduce it down.

If you want to chase this down I guess even in larger scale models it can happen (see attached).

This model I've converted from an .STL file, cleaned up manually and made sure it is solid.

In hidden edges that are very close (almost parallel) the plugin loses geometry:

![Before and Aftter "Merge Faces"](/uploads/imported_attachments/b6Hc_example2-cleanup.jpg "Before and Aftter "Merge Faces"")

Cheers and thanks for the response.

Larger scale model that loses geometry too.

![Illustration of the problem "lost geometry".](/uploads/imported_attachments/xKrD_Illustration.png "Illustration of the problem "lost geometry".")Hi Thom,

First let me say the CleanUp3 is great, it helps a lot!

Second: I've noticed that when I slide some parts of a model over an existing surface Sketchup tends to create a lot of coplanar triangles on the surface and when I use the CleanUp3 plugin it tends to say: "Face merge resulted in lost geometry!".

I've located one example and reduced the model to a small file with one group that presents this exact problem (attached) in hopes it'll help you perfect this great plugin.

My setup: Sketchup 8 Pro (8.0.16845, on Mac OS 10.6.8) with CleanUp3 3.1.9. All options selected in CleanUp except Merge Identical Materials and running "Merge Faces" both result in lost geometry.

Thanks Dave! That was exactly the case. The way I read the instructions gave me the impression I had to dump all the files instead of moving the directory.

Cheers

It looks like an installation error. My guess is that you either took the contents of the Curvizard_Dir_11 folder out and dumped them into the Plugins folder or you have that folder inside another folder which makes them not load correctly. Go back to the first post where the footprint for the plugin is clearly shown and make sure yours looks like that.

Hi Fredo,

First: you tools are great, thank you very much.

I installed Curvizard 1.2d today and got similar errors as above:

Error Loading File __loader.rb
uninitialized constant TraductorError Loading File bootstrap_Curviloft.rb
uninitialized constant Curviloft::T6Error Loading File bootstrap_Curvizard.rb

I have LibFredo6 installed:
LibFredo6.rb
LIBFREDO6_Dir_47

Are in my plugins directory and I'm running other Fredo plugins (Round Corner, Tools on Surface) without any problem.

Am I missing anything?

PS: my Sketchup is version 8.0.15157 running on a Mac OS X 10.6.8

Thanks
