New API doc - typos and questions

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)

View.write_image

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 or false on failure, not nil (from my experience.)

Entities.add_arc
http://code.google.com/apis/sketchup/docs/ourdoc/entities.html#add_arc

@unknownuser said:

Returns:
arccurve
an ArcCurve object if successful

It returns an array of edges instead.

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
http://code.google.com/apis/sketchup/docs/ourdoc/camera.html#set

@unknownuser said:

The initialize method is deprecated. It essentially does the same thing as Camera.set.

Camera.set does what Camera.set does? ... "Spider Pig! Spider Pig! Does whatever piderpigs does."

View.pickray
http://code.google.com/apis/sketchup/docs/ourdoc/view.html#pickray

@unknownuser said:

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

Returns:
ray
a ray

The "ray" is a Line; Array [Point3D, Vector3D] and the Point3D is the camera.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' ?

@unknownuser said:

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?

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...

Returns false, not nil when user cancels.

WebDialog.new

Two last parameters isn't explained.

BoundingBox.min

@unknownuser said:

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.

WebDialog.get_element_value
http://code.google.com/apis/sketchup/docs/ourdoc/webdialog.html#get_element_value

The example hasn't escaped the HTML tags - so the HTML sample text is instead interpreted by the browser..

Curve.move_vertices

Description says:

@unknownuser said:

The vertices method retrieves a collection of all vertices in a curve.

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.

Image.size=
http://code.google.com/apis/sketchup/docs/ourdoc/image.html#size=

It appears that the second argument is optional.
