I think I have to get a few of these books. Computational geometry: algorithms and applications let me calculate a 2D convex hull. (I had no idea what it was before.) http://books.google.no/books?id=tkyG8W2163YC&dq=Computational+Geometry:+Algorithms+and+Applications&printsec=frontcover&source=bn&hl=no&ei=bLYFS9r_DcP3-AbKiozWDQ&sa=X&oi=book_result&ct=result&resnum=4&ved=0CBkQ6AEwAw#v=onepage&q=&f=false

I think the defacto standard in this forum is that the original poster (e.g. you) edits his/her first post and adds [Solved] to the beginning of the title, to let people know there is a solution in the thread. I could be wrong, though, since I'm also quite new here...

Hi there! Take a look at the http://forums.sketchucation.com/viewtopic.php?f=180&t=17948&st=0&sk=t&sd=a, scroll down, find and download FredoScale 2.0h.zip. A brief explanation should also be there. Let us know if this helps. Oh, and FredoScale 2.0 requires LibFredo6 3.1 http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=17947#p144178

Thanks, Chris.

Thank you Thom and Martin.. I understand better now :

@honoluludesktop said: ... If so is it efficient? Twentieth century issue.

Thanks! That is exactly what I was looking for! I've updated my blog entry (http://www.cfcl.com/rdm/weblog/archives/001716.html) with some speculation on how this capability might be used.

Yeah i noticed a few of those, as well as some other problems Was having alot of issues trying to get it even to run a few parts of it the other night. Been reading the programming Ruby book found on the ruby-doc.org website. going to have to go through the code and tear it apart piece by piece over the course of this week, and hopefully have something workable by this weekend. Hopefully.

Yeah. Looking into it, there is a lot more work involved. I'd have to change my program quite a bit to fit it into this programming structure.

Jim has got the device working in a couple of browsers. He asked me to post these images on his behalf to see if anyone else is interested in this aspect - I am more interested in finalising the machine that runs this or other such devices from the desktop.

Have you tried SceneExporter, either to do what you want, or as an example of how it could be done? The Pro version will hopefully have the Save dialog working soon.

cheers dude

I found something that in the end could lead to a way of using ruby gems with SketchUp Ruby http://docs.rubygems.org/read/chapter/15#page101 and http://docs.rubygems.org/read/chapter/3#page83 I could not understand too much from that, but I hope that somebody will refine that in a easy to use manner.

I believe that they showed this during the IP conference this last year. Maybe dig through the IO videos to see if they had any sessions devoted to it. Chris

The nsetSketchupApi plugin is in a separate topic reserved for downloading, updates and technical questions and answers. Another topic "[WebDialog]Behind nsetSketchupAPI" starts a discussion on the potential of such an approach. But here I just want to thank Alex and Jim for prompting the development of an alternative type to Alex's cheat sheet; one that is based on animating words in a small machine-like interface rather than more familiar digital versions of paper pages. Most of all though I must thank Jim, ungenerously described as code adviser in the files, for teaching me about json, easing and all these things, but mostly for how to turn my cavalier code into something understandable and stable. Thanks Chris

i know, but a free drape much easier to use . what about multiple weld? or multiple divider (i.e. welding multiple lines/dividing at the same time for lofting purposes? )

Oh gotcha. The Prince IO game works because the user never needs to interact with model directly. All their actions are done through the web dialog and as soon as they click into the model, it must kill their game control then I guess? Chris

@thomthom said: You have a .hta application, you also use that in a Webdialog. You use WebDialog.set_file("myHTA.hta") and window.location.href = "myHTA.htm" ?? Firstly as htas are not compatible with Macs we thought we ought to try and get a WD version working for them. Secondly we know we can launch Sketchup from an hta but we haven't got as far as seeing how to manipulate within it preferably from a single plan/do interface. Anyway thanks again for your help. I thought you deserved some kind of explanation. Regards Chris

Perhaps this is gravedigging but I hae an AHA moment the other day. The reason the offset tool does not work with a single line is that it does not know what 3D plane you want the offset to be on. Two or more non co-linear lines and presto. SU can calculate the plane from any three points. Then determine the side you wish to place the offset on by tranforming the mouse cursor position to the plane. Double sided offset would have the same problem.
