New API doc - typos and questions

cjthompson

now I see why it doesn't work with arrays:


mesh = Geom;;PolygonMesh.new
mesh.add_point([0,0,0])
mesh.add_point([1,0,0])
mesh.add_point([1,1,0])
mesh.add_point([0,1,0])
mesh.add_polygon([1,2,3,4])
Sketchup.active_model.entities.add_faces_from_mesh(mesh)

you can use an array to index the points directly (for some reason, starting at 1)!

Can you test whether this is faster than point_at?

thomthom

I will see over the weekend. I found some slowness by having to use .add_point and then later use .point_index to build the polygons. building my own hash of Point3Ds and the index I got from add_point was faster.

Hopefully adding points in the add_polygon methods directly will be faster.

Oh yea - the index start at 1 is annoying as well.

cjthompson

I think I found what your problem is.

This works:


mesh = Geom;;PolygonMesh.new
mesh.add_polygon(Geom;;Point3d.new(0,0,0),Geom;;Point3d.new(1,0,0),Geom;;Point3d.new(1,1,0),Geom;;Point3d.new(0,1,0))
Sketchup.active_model.entities.add_faces_from_mesh(mesh)

This doesn't:


mesh = Geom;;PolygonMesh.new
mesh.add_polygon([0,0,0],[1,0,0],[1,1,0],[0,1,0])
Sketchup.active_model.entities.add_faces_from_mesh(mesh)

EDIT:
You can put the arrays inside of another array to get it to work:


mesh = Geom;;PolygonMesh.new
mesh.add_polygon([[0,0,0],[1,0,0],[1,1,0],[0,1,0]]) #this works
Sketchup.active_model.entities.add_faces_from_mesh(mesh)

Using .add_points first and using index references for .add_polygon seems faster than using Point3d's.

General

Class and method names could be turned into links
to the appropriate API page, for ease of navigation.

Sentences should begin with a capital letter and end with
a period (etc). Phrases should not.

If a modifying phrase is used at the end of a sentence,
a comma should be added for clarity:


  the name of the attribute dictionary  if successful
                            dictionary,

Although the page does not discuss this, setting a
custom attribute with a key that contains upper-case
letters does not work.

The page does not indicate how to set an attribute
(eg, '=LenX+20') to be used as an expression.

In the entry for AttributeDictionary.each, the "value"
argument is being formatted as part of the description
for the "key" argument.

Ditto for AttributeDictionary.each_pair.

On the API docs pages, in the left nav column, whenever you have made a link bold, the cursor changes to a caret instead of the hand cursor. I suspect it's the <b> and </b> tags doing this.
example from the API HTML source:

<li><a href="/apis/..../model.html"><b>Model</b></a></li>

Perhaps if the bold tags were outside the anchor tags?

<li><b><a href="/apis/..../model.html">Model</a></b></li>

If the css specifically set a tags such: a {cursor:hand} the nested bold tags should inherit their parent's cursor setting (according to the css reference.)

thomthom

The bold tag should not interfere with the cursor regardless if it's inside or outside the link element. It's default cursor property is inherit. It's either some override or other quirk. Could be a browser quirk.
In FF3.5 I don't see this behaviour. What browser do you use?

Currently still using MSIE 7

P.S.: at MSDN it indicates if the cursor is not explicitly set, the browser decides; so it may indeed be a MSIE quirk. (I have MSIE 8 and FF on the computer in another room, I'll check and see how the site looks on that machine later today.)

Tried with IE8 - cursor is normal.

It certainly wouldn't surprise me!

Point3d.<

@unknownuser said:

Returns:
true if the point2 is closer to the origin.

Following the example, I get he opposite result.
The Returns: should probably read,
" *true* if the point2 is **farther** from the origin; *false* if the point2 is closer to the origin (than the receiver.)

And the anchor link http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/point3d.html#%3C doesn't work for me under FF3.5. Might be due to the < character.

I suggest the Google webmeister change the anchor to "#lessthan" instead of "#%3C".

I would suspect that links to - and + methods may have problems with some browsers as well.

thomthom

The id for the anchor is invalid.

The correct format is:
http://www.w3.org/TR/html4/types.html#type-name

@unknownuser said:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

There are a number of other HTML errors as well. They use a XHTML doctype, but empty elements is not closed with />. Looks like HTML is used - despite the doctype.

The HTTP header claims characterset ISO-8859-1 while the META tag claims UTF-8

Characters isn't escaped properly, such as the < character in the method list. (line 342)

Run it through the validator and see 67 errors. http://validator.w3.org/check?uri=http%3A%2F%2Fcode.google.com%2Fintl%2Fnb%2Fapis%2Fsketchup%2Fdocs%2Fourdoc%2Fpoint3d.html&charset=%28detect+automatically%29&doctype=Inline&ss=1&group=0&user-agent=W3C_Validator%2F1.654#line-342

No wonder things isn't always working when there's so much invalid markup.

Thanks for all the feedback, Dan! Keep 'em coming.

How is your to-do list compared to Santa's list?

Santa's got nothing on me.

Edge.reversed_in?
http://code.google.com/intl/nb/apis/sketchup/docs/ourdoc/edge.html#reversed_in?

Why is the example using a begin rescue structure? Does it on occasion cause errors?

Dan Rathbun

The class Sketchup::HLR is undocumented in the API.

It's an Entity subclass.
It inherits all the Entity baseclass methods, and adds 2 of it's own:

.calculate* .num_faces

If you create a HLR object at the console, and call .parent (when it has no parent) a BUG SPLAT! results. See post: http://forums.sketchucation.com/viewtopic.php?f=11&t=24740#p212101

What is this class HLR used for? (.. as there is no .add_HLR method for the Entities collection object.)

thomthom

Tool.getExtents
http://code.google.com/apis/sketchup/docs/ourdoc/tool.html#getExtents

The example given isn't a good one. From my observations, clipping occurs only when you draw outside the model boundary. So returning model.bounds is pointless.

Sketchup.send_action
http://code.google.com/apis/sketchup/docs/ourdoc/sketchup.html#send_action

You can toggle the StatusBar on/off in Ruby (PC only?) via:
Sketchup.send_action(59393)

The following have no effect on my PC in SU ver 7.1.x:
Sketchup.send_action(21019) hide Status bar and VCB
Sketchup.send_action(21020) show Status bar and VCB
Sketchup.send_action(21022) hide Status bar and VCB?
..whereas the above id 59393 does work for just the StatusBar.

[ NOTE: I've moved my VCB up to the 2nd line of the Top Toolbar Container in 2nd position after the Layers toolbar, so I'd not want the VCB turned off with the StatusBar anyhow. I see them as two different things. ]
