I don't think so, thomthom. Components take colours from layer they are in. And if you select all entities in a layer (with Didier's quick selection plugin), you copy place them in a new layer?

That's a great idea, Bill. I've added it to the feature request list. Cheers,

@thomthom said: Just had another though, if you really want a modal window on mac? Not possible? Not currently possible, unfortunately.

@thomthom said: Can anyone elaborate ... Suppose you have 3 points (p1, p2, p3) and want a point (p4) "normal" to p1. The 3 points define the PLANE and also 2 vectors with origin in p1. If you make a CROSS PRODUCT between those 2 vectors, you will get a 3rd vector that is NORMAL to the PLANE and passing on p1. If you offset p1 using this new vector ... voila! Example: p1 = Geom::Point3d.new(1,2,3) (can be any 3d point, non hard coded) p2 = Geom::Point3d.new(4,5,6) p3 = Geom::Point3d.new(7,8,9) v1=p2-p1 or v1=p1.vector_to(p2) v2=p3-p1 or v2=p1.vector_to(p3) p4 = p1.offset(v1v2) or p4 = p1.offset((p2-p1)(p3-p1)) Regards Marcio

You should be able to calculate the volume, and the maths to work out the weight given the material type and density should be straightforward.

@thomthom said: That's great Dale! Works perfectly. But I would never that expected that .parent would return that. I would have expected that: > group.entities.parent === group > There are a lot of strange things about groups, and that is one of them.

I could only guess so quickly because it's happened to me a couple of times, too!

You need to look in the API methods for various bits... it's all there... Make a list of the loop's vertices. You get a vertex. You get its point in 3D You get the vertex's edges. For the two edges get its other end's vertex and thence its point. You get the vector between the vertex-point and that end-point in turn. You see if vertor1==vertor2 [or its 'reverse']. If they're not 'equal' then it's a corner... .

Yes, Gaieus, is very cool, I wish I could use it as soon as possible, but I don't have a project to work in it. best regards

Hello Ross - I don't know. I needed to enable the extension to see it in SU7 Pro, and it went away when I turned it off the Ruby Examples and restarted.

Glad you got it working finally!

Thanks Rick and Jim that helped!

I see. I never looked that that class yet. I just saw the UI::Menu class and thought that was the one. And there was nothing on the constants there. It says that UI.Command is the preferred way to add toolbars and menu items, but why? what's the difference and benefit?

Here's a link to a plugin that does what you want for max. Might give developers ideas on how to do it for SU. http://www.vg2max.spb.ru/PolygonMap.htm

Thanks for helping look into this Jim. GetSaveFile probably accepts the / as well. (I didn't test it). I have always been a little disappointed in UI.openpanel. Using Win32API.so (which requires that you install a second file with your plugin and only works with Windows Apps), lets me specify patterns for acceptable extensions, and also to specify a default extension to be appended if the user doesn't enter one. And the GetOpenFile version lets me require that the file exist before the use can hit OK. Small things. But it is too bad that SketchUp can't find the time to update some of their routines. (This could easily be done with either new routines, or optional parameters, to make them a little more useful.) However, the main point of the original post is that it would be nice if you could pass write_default() a string and have it save it and return it, without having to "reverse engineer" which characters don't work.

I had the same problem with this script in version 7. I downloaded the latest version and it worked. Try that. Best
