Creating components from existing objects

[thomthom]

Are your script also generating the geometry you want to place in the component? If so, then you should just add it directly to the component definition.

This seems to work.

mod = Sketchup.active_model
ent = mod.entities
sel = mod.selection

wgrp=ent.add_group ent.to_a #create a group containing all existing entities
wcmp=wgrp.to_component #convert the group to a component/instance.
wcmp.definition.name="World" #give it a name

Hi Tom,

The geometries are generated by the users as they go along. I'm trying to make this a tool so as and when the user switches to the tool, all of the currently existing models (except certain objects) become part of the miniature view

Ahhh! group to component! Thank you so much

Another question on a related note.

Is there a way to set the Level Of Detail on the miniature component instance alone?
It seems to be affecting performance with large models like castles and for the size at which I'm rendering the miniature, I couldn't care if its quality went down

There is always a way but at what cost. The code would no doubt expand from 3 lines to 3000.

Beware... if ents is model.entities and that's not the current 'active_entities' context then ents.add_group(ents.to_a) or ents.add_group(model.selection.to_a) etc will Bugsplat!

So... always ensure that the ents=model.**active_**entities and the objects you are trying to add to the new group are in the same context - hence the recommendation for 'selection' because the user can't manually select things that are not in the current active context...

TIG thanks. Will keep that in mind

You might play with the Fog settings. Adjust the near and far clipping planes. (But this is really not LOD.)

Thanks Dan. Will give that a try

I'm on a framerate sensitive medium, so anything I can do to improve frame rate would be useful. It would be great if you have any tips on how to set the LOD for the miniature.
