[Plugin] Simple Glazing tool

tomot

I see no ruby gurus willing to take a nibble yet?

Once the rectangle has been picked, its co-ordinates are defined
by $pt0 thru $pt3 (see below)

#------create a new set of points from the original 3 point pick
$pt0=Geom::Point3d.new($pts[0][0], $pts[0][1], $pts[0][2])
$pt1=Geom::Point3d.new($pts[1][0], $pts[1][1], $pts[1][2])
$pt2=Geom::Point3d.new($pts[2][0], $pts[2][1], $pts[2][2])
$pt3=Geom::Point3d.new($pts[3][0], $pts[3][1], $pts[3][2])

I can then create the required code that makes the glazing,
give it a transparent color, followed by "pushpull'ing" the thickness of the glass
whose value is $ggthick (see below)

#------create the Glazing
group=entities.add_group
entities=group.entities
base=entities.add_face($pt0, $pt1, $pt2, $pt3)
base.material=Sketchup::Color.new(163,204,204) #change the RGB Color numbers here
base.material.alpha = 0.6
base.pushpull $ggthick

All of the above will produce glazing in any plane xy, xz, yz.

However in order to set the glazing back from an xy plane, I need a z offset
equally for glazing on an xz plane needs a y offset, and for glazing on an yz plane
requires an x offset.

If I was producing a static glazing ruby where the glazing was always located at 0,0,0
then I could provide the offset option via $wwthick which is the "Glass Setback from face value.
as follows:

$pt3=Geom::Point3d.new($pts[3][0], $pts[3][1], $pts[3][2]-$wwthick)
but this will not work for the other 2 planes.

Is there a 3d point in Ruby that is not tied to the world co-ordinate system, but rather
to a local co-ordinate system?

or is there a way to do a double pushpull one for the offset and one for the glazing thickness,
and then erasing the first sheet of glass?

TIA!

Entities added to a group are relative to the Group's origin and axes.

Jim I don't know what I'm going to do with that piece of information
in a practical way to solve this problem.

As the attached pic shows, at present the glazing is flush with each face
of the 2 opening the glazing is installed into.
I would like to have the option of letting the user pick an offset back from
the face as is shown in the opening on the left side of the cube.

Jim

Well, you know the normal of the glass, just move the group forward or backward along the normal.

In other words, apply a transformation to the final group in the + or - direction along the base face normal.

Aren't you re-inventing Windowizer without a frame ? Currently you must enter something, but 0.1mm makes the frames effectively nothing...

Very clever tool and thanks.
As it creates a group it is very easy to move back and forth.
Good enough as it stands.

Not at all! Windowizer asks for 4 sided face to be selected first. While I use the "pick 3 point rectangle" method.
This is not a criticism of how Windowizer works, it has more to do with my workflow.
I design structures in SU using walls and slabs that have thickness. Then I punch openings in them for windows, doors, stairs etc., later I fill in those openings with the required components.

I find the "pick 3 points rectangle' method the most natural way to fill in an opening. If I were to use Windowizer, I have to fill in the opening prior to running the script.

However, I would be more interested in getting the setback problem solved.
While Jim's comments make a lot of sense, I can't get the code to work.

aargh!

Thanks! But after I have moved about 30 windows back 3" from the face. I
feel like my Grey matter is leaving for greener pastures.

Hi tomot,

Here is a snippet of your plugin with the transformation.



    base.pushpull $ggthick
    self.reset
    normal = base.normal
    normal.length = 2 # how far?
    tr = Geom;;Transformation.translation(normal.reverse)
    group.transform! tr
    model.commit_operation
end

Jim, please accept my great appreciation, with a reply HUG!

so here is the the attached update:

WindowGlass.rb

nomeradona

clever and useful indeed.. thanks

I asked a long time ago for windowizer to have ability to have "0" as the frame, and have it be left out completely... but all I remember getting was a "good idea Fletch"... while never seeing it implemented... I'm still waiting.

until then... this could be useful - thanks for sharing!... and true about the workflow... sometime nice to just draw interactively.

RickW

@fletch: Yeah, unfortunately, that happens a lot more than I would like. More ideas than time to implement...

JGA

Tomat, thanks very much for the tool.
RickW, Windowizer is one of the most useful tools available. However, could it be adapted to provide an inner frame of a window? I currently push pull through the wall, repair the faces & then use windowizer on both sides of the wall.

Yes I have a working copy, with glazing, frame and exterior trim however, I still have
a few bugs to resolve, before posting it.

@Rick,
ah well... c'est la vie...

In fairness to RickW, he has produced some amazing code.
I think he was the first one to create a dialog box in Ruby.
Without which all input Rubies could not exist.
