Yeah, that took like under a minute to fix.

Happy to know it got you sorted out.

Because I'm nosy, what are you modeling?

Hi Dave,

I'm making resin pendants from 3D printed moulds, and the lofts are part of the bails that contain the cord. I've done hexagonal and circular previously, now I need to create one to fit the square (rotated 45°).

Thanks for you interest,

Thomas (T/A @lightandmagik)

Since the arc at the left end is flat, you could put in an edge to fill that face.
Then run Curviloft for the rest of it.

Your smaller one has some stray edges sticking out and there are some strays off at a long distance from the rest of the model. One of them is over 100 meters from the origin. Might want to delete those things.

Dave, that is incredible, thank you!

Yeah, that took like under a minute to fix.

I owe you one, seriously

Hi,

I've been bashing away at this for hours now, and simply can't find a solution anywhere or work this out for myself. I'm so frustrated with this I've even considered switching to Blender, but wouldn't know where to start with a shape as wonky as this.

The smaller (older) set of curves skin fine in Curviloft, but the others report an error. This is one of the side faces of a jewellery bail, something I've modelled using Curviloft many times over without issue. It strikes me that the curves that skin aren't as clean and smoothly defined as the new ones, but other than that I have no clue.

Any ideas?

Thanks in advance,

Thomas

Smaller curves good, larger (newer) bad

Hi Guys,

There are quite a few threads on the forum concerning the translation of a component's axes, but I can't find any information on how to rotate them, while retaining the original orientation of the component itself. I've read through the API reference on vectors, but as a beginner I must admit to being rather flummoxed.

I have models (of cabinets) comprised of flat panel components and would like to be able to extract the co-ordinates of their face details as if each panel were flat on the X/Y plane (vector [0,0,1]) in order to generate simple GCode for CNC.

Any ideas?

Getting the size of an element with Ruby can be done with the boundingbox method.
http://www.sketchup.com/intl/en/developer/docs/ourdoc/boundingbox

Just get your box definition into a variable (for instance box_def) and use the methods
box_def = Sketchup.active_model.definitions["Box"] bbox = box_def.bounds w = bbox.width (same for depth and height)

Oh wow!

That works brilliantly, thank you!

The naming convention of width, depth and height seem the wrong way round but I can live with that. The code snippet below outputs the dimensions in the format 'name x y z'

# this lists component name and bounding box dimensions

model = Sketchup.active_model
entities = model.entities
entities.each { |entity|
  if entity.class == Sketchup;;ComponentInstance
    name = entity.definition.name
    defn = entity.definition
    bbox = defn.bounds
    w = bbox.width.to_l.to_s
    h = bbox.height.to_l.to_s
    d = bbox.depth.to_l.to_s
    puts name + " " + w + " " + h + " " + d
  end
}

P.S. Sorry about the thumbs down, I hit it by mistake and it wouldn't let me change it

Okay,

I've been lurking here a while, but now it's time to raise my head above the parapet!

Been an AutoCAD user for about 25 years and coded various widgets in AutoLISP, Visual Basic (and a bit of C/Arduino), and I'd really like to get started with Ruby.

I've already built a few DCs from the GUI, quite happy with building parametric components and even building simple models from Ruby, but here's the problem...

Is there any way to get dimensions (lenx/y/z) values without setting attributes?

If I make a box, and convert it into a component called 'Box', about the only thing I can get from Ruby is it's name. Lenx for example, returns zero until I go to the GUI and add the attribute manually. Is there any way to set attributes to their default so they can be read by Ruby?

If I use an attribute explorer, I can see real dimensions in _last_lenx/y/z so theymust be readable somehow?

Many thanks in advance!
