For animations it's best to use the Animation class instead of using sleep() and forcing a screen refresh. http://www.sketchup.com/intl/en/developer/docs/ourdoc/animation

The C API allow you to read and write files. For .NET integration you would have to create a wrapper that bridges the two.

Thank You Very much.

Try the groups' .bounds if they 'touch', then some_group.bounds.max.x OR .y OR .z and some_other_group.bounds.min.x OR .y OR .z might be coincident ?? Especially if the are simple boxes...

There is no way to force a statusbar text to stick around. It's normally set by the active tool, but also by menu and toolbar items. Do you have a sample snippet that demonstrate the issue?

Thanks again TIG! I am very grateful. I knew I was missing something, but was pretty much stumped. Thanks for putting me back on track, and so quickly. Cheers

I'm sorry I have tried that .. but that is not what is in my mind.. I just want the text to follow the line even if I move one point only . . doing this manually is possible.. but not for ruby scripts I think..

Hi John, many thanks for your quick reply. It was really helpful. I am now using the command line of winzip in my Powershell script, as you have proposed. The generated RBZ file is now working on my MAC also. Thanks a lot for your help. Sonja

great - that's what I was looking for anyway

**It works!**Thanks a lot, you saved my weekend!

The code is good. From the console it appears that the first run was ok, and then you ran again the script and the face cannot be created. The problem is that you are trying to create a face object in the same place occupied by the face created before. Clean all your objects first (select all> delete), and try again.

It adds a face within the overall form too. The 'window' is colored after the explosion. Note how I also only make a 'Red' material once. You could erase the 'window' instead of making it 'Red'... The order of operations and exploding groups affects the result, but knowing that you can avoid it.

On the PC, send_action can process native tool command integer IDs. I pub'd some IDs here (but do not use that file as is. It mods the API.) Just use it for tool ID reference. Somewhere here Thomas also posted a tool ID hash. Ex: Sketchup::send_action( 24201 ) # Union Tool

That's for that revised version!

Your error message pointed to the last line in your code: classify (u, apoint, face1) I suspect it was the space between the method name and parentheses. Especially when you encounter syntax error it's good to go over your code and make sure the code style is consistent. Checking that there are no spaces between parentheses in method calls and making sure you have parentheses around all arguments etc.

Sounds like you need to implement a custom Tool: http://www.sketchup.com/intl/en/developer/docs/ourdoc/tool You can make the tool select entities the user clicks on by using the PickHelper class. Both these classes has examples in the documentation that will get you started.

From a time complexity perspective I think the problem is inherently O(n^2) (which means that your code can't be any simpler), also, if the curves have few segments and you already know enough to throw away half of them, then I would say your code is probably close to optimal. In general, the simplest way to gain speed is to use bounding boxes in various ways like reducing the input to segments in the bounding box intersection between the curves and so on, however, there are constant costs associated with this so it may not be a gain on small inputs.

Ah, yea - there is name and display_name - at least in the Ruby API. name is the unique one that should be used to refer to materials. display_name should be used only to display the material name to the UI. However, it appear that the C API doesn't quite do that. Let me have a chat with the rest of the team.

I can reproduce what you see when I use a larger texture. I also notice that the Console output is odd. lots of empty lines and a strange order of the lines. I'm not sure what it is yet.
