Text position problem

Jorgensen · 2 Feb 2008, 22:10

I'm working on my very own (noooooob) area script.

And now I'm having my first problem - when add a text to a face in Sketchup, by doubbleclick, the text is visible from allmost every angle, but if I use

coordinates = object.bounds.center
model = Sketchup.active_model
entities = model.entities
point = Geom::Point3d.new coordinates

$area = (object.area / (39.3700787*39.3700787)).round
$text = "#{object.layer.name}\n#$area m2"
$textObjects.push(entities.add_text $text, point)

It seems like the text is being cut by the face - is there a way to avoid this ?

And a other small thing - how do I add a ² to the areatext ?

Thanks
Jorgensen

Here is the complete script:

$textObjects = Array.new

def tmTextAdd
tmSelectAllFaces
model = Sketchup.active_model
ss = model.selection
for object in ss

end
ss.clear
end

def tmSelectAllFaces
model = Sketchup.active_model
ss = model.selection
ss.clear
for ent in model.entities
if (ent.kind_of?(Sketchup::Face))
ss.add(ent)
end
end
end

def tmTextDelete
if $textObjects.length > 0
$textObjects.each do |e|
if(not e.deleted?)
e.erase!
end
end
$textObjects.clear
end
end

#tmSelectAllFaces
#tmTextAdd
#tmTextDelete

#---------------------------------------------------------------
#- Setup menu -
#---------------------------------------------------------------
if(not $TM_area_loaded)
Mejeriet_menu = UI.menu("Plugins").add_submenu("TM").add_submenu("Arealer")
Mejeriet_menu.add_item("On") { tmTextAdd }
Mejeriet_menu.add_item("Off") { tmTextDelete }
end
$TM_area_loaded = true

I've done a bit cosmetics to your script and put all the code togehter (you wrote, "complete script", but the text-adding wasn't in)

$textObjects = Array.new

def tmTextAdd
  tmSelectAllFaces
  model    = Sketchup.active_model
  entities = model.entities
  ss       = model.selection
  for object in ss
    point = Geom;;Point3d.new object.bounds.center
    area  = (object.area / (39.3700787*39.3700787)).round
    text  = "#{object.layer.name}\n#{area} m²"
    $textObjects.push entities.add_text(text, point)
  end
  ss.clear
end

def tmSelectAllFaces
  model = Sketchup.active_model
  ss = model.selection
  ss.clear
  for ent in model.entities do
      ss.add ent if ent.kind_of? Sketchup;;Face
  end
end

def tmTextDelete
  unless $textObjects.empty?
    for e in $textObjects do
      e.erase! unless e.deleted?
    end
    $textObjects.clear
  end
end


#---------------------------------------------------------------
#- Setup menu -
#---------------------------------------------------------------
unless $TM_area_loaded
  Mejeriet_menu = UI.menu("Plugins").add_submenu("TM").add_submenu("Arealer")
  Mejeriet_menu.add_item("On") { tmTextAdd }
  Mejeriet_menu.add_item("Off") { tmTextDelete }
end
$TM_area_loaded = true

And for me it worked. I can see all texts from all directions.

Hi azuby

Thanks for your help - but I still have the problem that the text gets cut off - se images.

The 'test' text is added via mouseclick and does not have this problem

EDIT
Is this the proper group/place for such technical questions ?

azuby · 3 Feb 2008, 18:30

Hmmm maybe it's a problem with OpenGL?

If I afterwards manual move the text 200mm, on the blue axis, the problem dissapers.

But how do I do this automatic ?
point = Geom::Point3d.new object.bounds.center
Adding 200mm to the Z axe of point ?

Sorry, I have quite a lot questions.... and still a lot to come

Thanks
Jorgensen

Adding a small leader to the text would solve the problem (if you don't mind having such text)

For instance:
text = model.active_entities.add_text "your_text_here", point, Geom::Vector3d.new(0,0,10)

increase vector.z value to get greater leader. What I often do is to have the same value for text height and vector.z value
Hope this helps,

Jorgensen · 3 Feb 2008, 20:05

Thanks Didier - I added point.z = point.z + 6 - this helped

BTW, your way of calculating (converting from inches2 to m2) areas is quite strange.

$area = (object.area / (39.3700787*39.3700787)).round
$text = "#{object.layer.name}\n#$area m2"

Try this:

$text=Sketchup.format_area object.area

Whatever unit the user has set, area (numeric) will be converted to this unit (string) and a ² is added to the text as well

Jorgensen · 4 Feb 2008, 19:47

Hi All

Thanks for your input.

@Didier
I have tried that - belive me - but I don't no why, but if I do an Object.area on a face that is 1000x1000mm I get an area of 1,550m2 ? And I have setup units in Model Info - strange ???

Another problem. If I doubbleclick the mouse I get a 'attaced' text, that keeps the position inside the face, even if I move the sides. This does not happen when using Object.add_text does any know if it is possible to achieve this by script ?

What I'm trying to create is a small script that has the function as I have tried to sketch on the attached image. This would be very useful for me when sketching plans

The next problem - how do I get group names, add listing them inside a group and adding text inside this group - a lot to learn.....

Didier Bur · 4 Feb 2008, 20:43

Jorgensen,
Try attached script.
Acces it via context menu, when a single face is selected in the model.
It creates a formatted text on a layer "Areas".

For the rest, I don't understand exactly what you mean (groups, and so)...

txt_area.rb

Jorgensen · 4 Feb 2008, 21:13

Hi Didier

I will have a look at the script.

What I main by groups. Is, that I have:

a ground level wich is on Layer 00
first floor in layer 01

On layer 00 (ground level), I would like a group that contains a 'area group' for each room, Kitchen, livingroom, and so on... .Each areagrop should have the name of the room, so that a script, can update the Text and area.

So, in the maingroup on layer 00, holds a text (on layer 0t Text) that says kitchen size ...., and a group named Kitchen (on layer 0A Area, so it can be turned off).

A bit dificult to explain

Didier Bur · 5 Feb 2008, 18:02

OK, I understand.
This is doable, but I have not much time to help you by now
Remind me...

Jorgensen · 5 Feb 2008, 20:18

Hi Didier

Thank - you have allready helped. I'll se what I can fix myself.

By the help from this forum, it might be possible

Hi

I have a question about the Sketchup.format_area utility.

My model is in mm, but I would like the result to be in m2 not as Sketchup.format_area shows mm2 - is this somehow possible ?

Thanks

Jorgensen · 7 Feb 2008, 07:59

Its now going the right way...

I have one question.
I have a group on each level of the building (the levelGroup). Each levelGroup contains a number of groups, that holds info for each room, the area and name. roomGroups.

I then doubbleclick, and get inside a levelgroup, and update the roomGroups.

To keep track of the roomGroups I use:
target = Sketchup.active_model.active_entities;
$areaObjects.push target.add_text text, coordinates

I then have an array $areaObjects, that cointain all the text added (roomGroups).
If I wan't to delete/update all the text, I can read the array again and then erase! them, but this will delete all the text on in all levelGroups.

Is there a way to tjek if the roomGroup is inside the active group ?

Thanks
Jorgensen

@unknownuser said:

Yes:
Switch to meters unit just before the format_area instruction, then switch back to mm:

old_unit=Sketchup.active_model.options["UnitsOptions"]["LengthUnit"]
Sketchup.active_model.options["UnitsOptions"]["LengthUnit"]=4

then_call_the_format_area_instruction_here
(result is a string so it would'nt be affect by later changes)

Sketchup.active_model.options["UnitsOptions"]["LengthUnit"]=old_unit
(to switch back to mm in your case

Jorgensen · 7 Feb 2008, 18:21

Hi Didier

Thanks for your reply. Just the way I would do, I just could'nt find the settings in Ruby.

One problem however, the text now becomes 14 Meters2 - should be 14 M2 - I guess I'll have to do somekind ereg_replace....

Thanks for your help.

Jorgensen · 7 Feb 2008, 18:26

Easy area = area.sub("eters ", "")

This is fun

TIG · 7 Feb 2008, 18:31

I did an AreaFormat tool a while ago... see: http://www.sketchucation.com/forums/scf/viewtopic.php?p=12808#p12808
It could easily be adjusted to suit your current units if they are not listed...

Jorgensen · 7 Feb 2008, 18:54

Thanks TIG - I'll have a look at it...

Right now I have a problem, actual the last before I can use the script at work...

I use this to tjek and delete objects in the active group:
def tmAreaDelete
objects_active = Sketchup.active_model.active_entities
for object in objects_active
if($areaObjects.include?object)
object.erase! unless object.deleted?
$areaObjects.delete object
end
end
end

What teases me, is I have to run the tmAreaDelete tree times to delete all text objects - and I just can't se why It works if I skip the line '$areaObjects.delete object' but that can't be a good solution.
