@unknownuser said: Adam, can you show me a picture of what you mean for the first case? Todd, 2 objects next to each other: [image: bXJr_SketchUpScreenSnapz005.png] Whats the smallest clearance? ie You can't do this by examining vertices. Typically you'd use GJK to crawl around the surface. But I seem to remember GJK is just for convex hulls - one of the many many reasons physics packages only deal with collections of convex hulls. (its an interesting subject - imagine a tumbling object through space with a protruding part and the incredibly complex path the tip of that protrusion traces.) Adam EDIT: I realized I claimed earlier that convex shapes would be simple.. I meant that with simple interval arithmetic you can find a separating plane etc. Nothing is ever simple..the devil is always in the details!

Thanks Dave I was having some trouble with a component you made it all clear

Hi, The error message cannot be the one you're showing: ans=Geom.Point_in_polygon_2d point,points Point_in_polygon_2d is not the name of a method and "point_to_polygon_2D" is in the error message. "in" instead of "to", upcase...

Also, webDialog callback actions don't get changed if you have persistent instances that call the dialog.

Yeah Was it like this today for you ?

I know this does not answer the question about downloading the API, but it does address david's comment about updates. The Groups Documentation is updated by Todd and myself as we get time and feedback. AFAIK, it is now more accurate than the standard online API documents accessed via the Sketchup Help>Ruby Help link.

Hi, I think what you after is already available. Its called Flightpath2. You have to pay (a small price) for it. Visit: http://www.smustard.com/script/FlightPath2 Regards Mr S

yeah i already knew that one. But thanx anyway, did you already found different solution

Thanx Jim... i had some other solutions but they give me different codes back. By know i found that thecodes are the same as on the powerpc-darwin OS. I think ineed to work on this part"elsif RUBY_PLATFORM == "powerpc-darwin" then" I think on my imac it passes this on cause i have intel duo core... So if you happen to know the code for this part

This is the documentation page I use - it's the most up-to-date: http://groups.google.com/group/SketchUp-Plugins-Dev/web/Ruby-classes.html Todd and Rick get all the credit for updating the docs - it's a thankless chore, no doubt. I wish there was a way to see what changes have been made to the documentation. I've asked that document updates be logged for us, but maybe I'm asking too much.

You could capture keystrokes in a modal webDialog - this will override any SU keyboard shortcuts - but beware irritating users who are used to using a shortcut for "select" that effectively cancels any active tool. Either query the shortcut list for the "select" shortcut and use it to cancel your modal webDialog, or create a really obvious "cancel" button or key.

Dave, Thanks for the tip, I will try it! I would have never thought solution like this.

x,y,z = $Vec1.to_a if (-y && x>0) ... do your code end also try not to use global variables (see this discussion)

I'd welcome this as well. I've developed my own manual work-around to essentially create my own images and substitute them for the ones created by the Sketchup web-exporter. Once you generate one web export say for 36 images you can re-use the html code multiple times and simply replace the images with those that you create on your own. see my post here: http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=10855

Thanks you for your suggestion moris , now I have found the right way

I will re post this Ruby with your added code, since some members may not know how to cut and paste code snippets into Ruby files. WindowGlassFrame.rb

This is just to show that TIG's V1.8 works well with quite complex shapes (I have posted this before, but what the heck!). The below images show the volume slices for a 1% accuracy volume calculation, which took many minutes to complete.

Got it Todd, thanks for the help...and thanks a bunch for the script, worked like a charm!

Wow, matrix seems to be a fantastic script. Never heard about it before . And thanks @TBD for cheating this useful randor script. Implementing an option would be a help indeed .

Thank you very much!!
