Info about add_note method

Dan Rathbun

I think I put a bug note at the bottom of the API page... yur not dreaming.

Here it is

Anyone experiences that the notes moves about?

Seems that if you use model.add_note when you are inside a group or component the note is added to that context and will shift about on the screen when orbiting.

Dan Rathbun

Well that method is a wrapper method (so it makes sense.)

It creates a Sketchup::Text object with leader set to hidden, and always face camera to true.
And I think it goes on the current layer.

So you may want to just want to use: model.entities.add_text

API Doc Error: Model.add_note() returns a Sketchup::Text instance object.
There is no Note object in the API.

How? I looked at add_text, but it appear to only accept a 3D point - not a 2D screen point.

Dan Rathbun

You are correct. Strike what I said.

There is some unexposed setting. (vector and point are set to nil when you use Model.add_note, but we cannot pass nil to the setter methods of Text objects.)

A note has the model as .parent, but when you do that in a component edit context, it gets the ComponentDefinition as it's parent.

Any way to move it out of the definition's entities collection, and into the model's ??

Group it (group1), add instance of group in model.entities (group2), explode group2, erase group1 ?

Dirty hack - but better than closing the open group/component. I'll try.

TIG

If you are adding the note in code then undo the edit context back to the model entities before adding it ?

model=Sketchup.active_model
###
model.close_active while model.active_path
### NOW add 'note' in the current entities - which are now the model's

It did add a Sketchup::Text entity to model.entities, but it is not visible. :s

That's what I'm doing now. But it's not a good solution because:

It takes the user out of the current context.
model.close_active is bugged - it doesn't add the event to the undo stack so then you undo the operation geometry gets shifted incorrectly because the change of context transformation is not accounted for.

Dan Rathbun

A bug, for sure.

I thot about:


n = model.add_note("Note text.",xf,yf)
inst2 = model.entities.add_instance(inst1.parent,inst1.transformation)
eg = inst2.explode
del = eg.find_all {|e|
  !e.is_a?(Sketchup;;Text) ||
  ( e.is_a?(Sketchup;;Text) &&
    e.point=nil && e.vector=nil )  
}
txt = eg - del
eg = nil
model.entities.erase_entities(del)
n.erase!

Because the 'note' is always [?] being added to the 'active_entities' it's safe for us to group it immediately.
note=model.add_note("NOTE", xf, yf) gp=note.parent.entities.add_group(note) gi=model.entities.add_instance(gp.entities.parent, gp.transformation) gp.erase! gi.explode

As I'm typing this untested... we might need to work on the add_instance transformation[s] bit

Can the text and the position of this note be animated?
For example can I make a timer with this?

Is it because the transformation needs sorting ?
Unfortunately, I think that if you group any 'screen-text' and then explode it it loses its screen-text-ness

Dan Rathbun

The native MoveTool can move the note.
