Thank you for taking a look at this problem. I looked in the ruby console and there is this error shown:
Error: #<NoMethodError: undefined method name=' for nil:NilClass> C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/Slicer.rb:575:in calculate'
C:/Program Files (x86)/Google/Google SketchUp 8/Plugins/Slicer.rb:992

Does it give you a hint to the source of the behaviour?

I have tried some rotations and slice-directions, but never get a flattened version of the slices. I attached my testmodel.

slicer_example.zip

Hi TIG,
I have tried the slicer script with a very simple geometry, but there are no flattened slices. Is the choosen geometry the reason for this? Is there an easy way to get the holes in the slices automatically? (SU8 M2 free)
Thank you!

I have not tried yet, but the plugin http://forums.sketchucation.com/viewtopic.php?t=41441 (by Aerilius) seems to solve this problem?!

Some little Doh!s about the text tool (they all are in the online manual, but who read it?!):

• If you doubleclick a face with the text-tool, the text is connected to that face without a leader line (not as screen text!)
• Leader text have two styles (View Based and Pushpin) changeable in the element info window (and I like the view based (not standard) much more...)
• By clicking on an corner of a group or a component the name of that element is shown
• Double click on enter ends editing of text
• ...

Thank you for yur helpful tips! It's a pity that this relatively simple action is not done correctly with the native tool, because it will often confuse beginners...

Does anyone have a tip how to do this offset without the "error" in left corner or whats the reason for this?
Thank you!

Hallo,
ich denke, wenn Sie den Stil auf den Standard zurücksetzten (in dem Schnitte, ... anzegit werden) und dann die vorhandenen Schnittflächen entfernen, wird wieder Alles da sein (auch in Version 8)...

You can find the "puzzle" exercise model in this topic:

Here is my second model for beginners who want to exercise the tools rotate and move:

Can I import it as (or easily make it into) a single edge ?

Plugin weld.rb should help.

@susteve said:

also what are coplanar faces ?

That are faces in one plane (normals are parallel).

For me the standard material shows the colors from front- and backside like defined in the style dialog. Or what do you mean by default material?

I dont't thinks that there is a difference between the front face color (style dialog) and the standardmaterial, because if you change the color in the styles dialog, the standard material changes, too.

... This model is perfect for practising the alignment (and lock) of the rotate and protractor tools, too.

I didn't had this in mind... but great idea!
I think I will create another exercise model for aligning and rotating in the next days I think somethink like a (3D?)-puzzle will do ... other suggestions?

...Double click on another white face, it repeats. Double click on a BLUE face, it SUBTRACTS two feet.

It is always in the direction of the positive face normal (white=front).

I have created a little model for beginners with which they can practice the navigation with a scroll wheel mouse in google sketchup. Any suggestions for improvement are welcome!

... API method for making textures unique ...

That was my first thought and because I never tried to program my own ruby scripts, I decided to take this example as a start...
After one evening watching ruby-tutorials I searched in the documentation for a method,... to make unique textures and ... gave up.
So my ruby entry have to wait and I will try your script. Thank you for sharing!

@dave r said:

That will replace the existing material with the new one on all surfaces in the context in which you are working.

I think this will not help with this problem because every face has its own material and I have to make them unique one after another. Or do someone know a plugin which do this for every face in the model?

I have attached a render of the edited model, the original one can be found in the 3D warehouse here:
http://sketchup.google.com/3dwarehouse/details?mid=ec48731154d046f6ec9203a885ed4d24

Here is an example: the left picture shows the windows before and the right after "make unique texture" for the faces of the window and the wall. (rendered with Indigo Renderer)
