Hi,
@georglorenz: try the script I have attached and see if it works better.
Regards

That worked! Thank you Didier!

Here is what I understand you did to the syntax:

model.start_operation "randomflipc"
changed to:
model.start_operation("randomflipc")

results = UI.inputbox prompts, defaults, "Random Scale Parameters"
changed to:
results = UI.inputbox(prompts, defaults, "Random Scale Parameters")

UI.menu("Plugins").add_item("gxl random flip"){gxl_randomflipc}
changed to:
UI.menu("Plugins").add_item("gxl random flip"){ gxl_randomflipc }

Is there a general guide or forum discussion for sketchup 8 syntax that would help me avoid these pitfalls in the future?

Thank you again /g

Btw, the API docs are lying:

I knew it. I knew it! No of course I didn't. Thank you much.

You are right it will do the same thing as the slider, but I am hoping for more fine-control inserting the values. The slider is really akward to control especially when you are doing elevation drawings and want to fade out the background.

Thanks again. You are the man thomthom.

I tryed this way of creating a reflective floor, the problem is when you render the scene with shadows, they go straight in the ground and don't change their direction as symetrically as they 'd do in real life (on a reflective face); I mean the shadows have the same slope in the whole scene, including the "reflection". But this is only a detail...

TIG: Thank you. It works. Don't ask me why. Your and my code are identical with the exception of a couple of blank lines. I checked that twice and then again. And side by side. And then again. And I have no idea. But it its working. 😄

I added input for xyz coordinates as you can see on the image. The crinkled surface was distorted only along the z axis, the top plane of the cube was distorted in three dimensions.

This is just for fun. Please use at your own risk and save before using. It crashed on me a couple of times already.

Thank you much for all your time. G
