[REQ] Automatic Labels or Dimensions ?

Box

I realised after I posted that you wanted auto on multiple Lines.
I can't think of anything that will do that just now.

Does this yet existing for a selection of straight lines in one click ?

True dimensions have a "dynamic" quality that a plugin's add_text can not duplicate. However, if the length label you would get from selecting the midpoint of a line is sufficient, then that can easily be done.

mod = Sketchup.active_model
ent = mod.active_entities
sel = mod.selection
begin
 edge=sel.first
 spt=edge.start.position
 ept=edge.end.position
 mpt=Geom;;Point3d.linear_combination(0.5,spt,0.5,ept)
 dim=edge.length.to_s
 grp=ent.add_group;ge=grp.entities
 txt=ge.add_text(dim,mpt,[0.5,0.0,0.5])
 txt.leader_type=1
 txt.arrow_type=3
 sel.remove edge
end until sel.empty?

Cool for the effort...
But seems there is a glitch
and very difficult to input on the ruby console without carriage return to line!

Error; #<SyntaxError; (eval); compile error
(eval); syntax error, unexpected tIDENTIFIER, expecting $end
... ent = mod.active_entities sel = mod.selection begin edge=se...
                              ^>
(eval)

Maybe errors come from the difficulties to input inside the ruby console!

Sorry about that. I always use Ruby Web Console to create and run short plugins such as this one. Here it is as a "one" liner.

mod=Sketchup.active_model;ent=mod.active_entities;sel=mod.selection;mod.start_operation "auto label";begin;edge=sel.first;if edge.is_a?(Sketchup;;Edge);spt=edge.start.position;ept=edge.end.position;mpt=Geom;;Point3d.linear_combination(0.5,spt,0.5,ept);dim=edge.length.to_s;grp=ent.add_group;ge=grp.entities; txt=ge.add_text(dim,mpt,[1,0,1]);txt.leader_type=1;txt.arrow_type=3;end;sel.remove edge;end until sel.empty?;mod.commit_operation

Just for fun, here is an attempt at creating a "dimension". The problem is that it is so view dependent.

mod=Sketchup.active_model;ent=mod.active_entities;sel=mod.selection;mod.start_operation "auto dim";begin;edge=sel.first;spt,vec=edge.line;ept=edge.end.position;dim=edge.length.to_s;vec.length=edge.length/2.0 - dim.length;grp=ent.add_group;ge=grp.entities;ge.add_line spt.offset([0,0,1]),spt.offset([0,0,6]);ge.add_line ept.offset([0,0,1]),ept.offset([0,0,6]);txt=ge.add_text(dim,spt.offset([0,0,5]),vec);txt=ge.add_text("",ept.offset([0,0,5]),vec.reverse);txt.leader_type=1;txt.arrow_type=3;sel.remove edge;end until sel.empty?;mod.commit_operation

Nothing in ruby

But TIG gave the basic idea to make it: you store a dimension as a component, then you stretch and move it according to the end position of the edge extremities

I used his idea in this plugin

it should be possible to adapt it the way you want it to work, by pre selection

@Giro
Missed this one!
I will exam it!

Edit: ok I use it ! It's a cool plug but you must click on each thing!

If I have 1000 segments separated i must make 2 * 1000 clicks !
Or I miss something as you speek about a "pre selection"

Ps And works only on the horizontal plan ! So not so good for my vertical segments!

Bravo!
Now That is prefect for the first one!
Second is more funny

Excellent!

i know this plugin doesn't exactly meet the need

i just suggested that it would be possible to adapt it, by retrieving the end points of a selection of edges, and adapting a dimension/component to them, in bulk

i plan to update the plugin for altitudes, not for vertical edges

do you really have 2000 edges to dimension? or is it an hypothesis...
