Behavior.snapto
I see two problems with the documentation of this method (I would like to call it a property, but that is probably my C# habit talking):
The "Returns:" section says it returns true or false, but it actually returns one of the 4 values listed in the description above "Returns:" (the default seems to be SnapTo_Arbitrary). The first sentence of the description ("The snapto method is used to verify the status of a component's "snap to" behavior.") also implies that the return value is a status, not the actual "snap to" selection.
It would be very helpful if the documentation of this method would make it clear that the value of Behavior.snapto works in conjunction with the value of Behavior.is2d to set the "glue to" behavior. If is2d equals false, the component will not glue to anything, no matter what value snapto returns. If is2d equals true, the component will glue to faces matching the snapto value.
I donβt think it is at all clear that these two (snapto and is2d) are related. It would be helpful to include a reference to snapto in the description of is2d, also.
This second issue applies equally, if not more, to the snapto= and is2d= methods.

Pages.add should contain some of this information about the meaning of the flags argument.
[ and also, Pages.add returns a Page object, not nil. ]
# The Page Constants Object.constants.grep /^pag/i ["PAGE_USE_SECTION_PLANES", "PAGE_USE_ALL", "PAGE_NO_CAMERA", "PAGE_USE_CAMERA", "PAGE_USE_RENDERING_OPTIONS", "PAGE_USE_SHADOWINFO", "PAGE_USE_SKETCHCS", "PAGE_USE_HIDDEN", "PAGE_USE_LAYER_VISIBILITY"]
model = Sketchup.active_model pages = model.pages index = 0 page = pages.add("New Page", PAGE_USE_ALL, index)
If you want to pick and choose which options, bitwise OR (

) the options together:model = Sketchup.active_model pages = model.pages index = 0 page = pages.add("New Page", (PAGE_USE_HIDDEN|PAGE_USE_CAMERA), index)

From my tests,
write_image
will accept several common image formats - .jpg, .bmp, .png at least. There is no mention of this in the docu. Just include the extension in the filename - as in "path/to/my_image.png"If you do not provide the optional width or height, the image uses the View Size for the written image.
write_image returns
true
on success orfalse
on failure, not nil (from my experience.) -

PolygonMesh.uv_at
Arguments; index The index for the texture coordinate.
Doesn't include the second argument, which is true for front face coordinates, false for back face.
PolygonMesh.uvs
Doesn't include the required argument, true for front face coordinates, false for back face. -
Camera.set

The initialize method is deprecated. It essentially does the same thing as Camera.set.
Camera.set
does whatCamera.set
does? ... "Spider Pig! Spider Pig! Does whatever piderpigs does." -
View.pickray

The pickray method is used to retrieve a ray passing through a given screen position in the viewing direction.
Returns:
ray
a rayThe "ray" is a

; Array[Point3D, Vector3D]
and the Point3D is thecamera.eye

I hope Scott stops by soon. He's got a lot of stuff here to pick up

Looking back at this thread I can trail the subjects I was looking into while making plugins. Like breadcrumbs.

UI.menu lists the valid menus titles, one is 'Create' isn't it 'Draw' ?

Point3d.offset (http://code.google.com/apis/sketchup/docs/ourdoc/point3d.html#offset) Description of the length parameter:
(optional) the distance to offset. If not provided, the offset is my a distance equal to the vector length.
Suggestion:
The (optional) offset distance. If not provided, the point is offset a distance equal to the vector's length.

Face.mesh
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/face.html#mesh@unknownuser said:
The mesh method creates a polygon mesh that represents the face. See the PolygonMesh class for more information.
Valid flags are:
* 0: Include PolygonMeshPoints, * 1: Include PolygonMeshUVQFront, * 2: Include PolygonMeshUVQBack, * 4: Include PolygonMeshNormals.
Add these numbers together to combine flags. A value of 5 will include all flags, for example.
The example uses
7
. Typo or undocumented feature? -

. Typo or undocumented feature?You can bit-wise OR the options together. 7 means 4 + 2 + 1, so normals, front UV, and back UV.

@unknownuser said:
For acolor it's always = 255 [100% opaque]... there is a color.alpha= method but it's never ever worked, you must set alpha [transparency] for a material itself not material.color e.g. material.alpha=0.4 for 40% opacity will work but the material.color.alpha still reports 255 [100%], if you try to change it, it just does nothing !
So to recap - the fourth item in a SUp material.color array is its alpha [r,g,b,a] but it's not used ! The alpha of the material itself works as a 0 to 1.0, equivalent to % setting of opacity...

BoundingBox.min

returns: a Point3d object representing the point where x, y, and z are the maximum in the bounding box.
Im guessing it should say minimum.

Tool.enableVCB?
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/tool.html#enableVCB?@unknownuser said:
The enableVCB? method is used to tell SketchUp whether to allow the user to enter text into the VCB (value control box, aka the "measurements" panel). If you do not implement this method, then the vcb is disabled by default.
I've never used this method for my Tools. But the VCB has still worked.
