Help with recursive component?

Al Hart

I am having trouble with the component in the attached model.

Only one Component appears in the SketchUp Components in Model window.

When I try to drill into the component, I see other components - such as Component #39 in the Entity Info Window.

When I Click on the main Component in the Component Window, I get the message "Cannot Create a recursively defined model or component"

I presume the component probably is recursive.

Is there an easy way to find it or fix it?
(Fix Model from the statistics window did not help)

I'll have to Expand the component browser view to see all the components. When you import a model, all it's sub-components are marked as "internal" and hidden by default in SU.

Sound like, and looks like from your screenshot, that you're trying to insert the component into itself. It's not the component being recursive - it's your actions that try to make one.
In your screenshot - if you exit the current context you should be able to insert the component you picked from the browser.

Thanks ThomThom. I guess I can learn something new every day.

Is this "expand" thing new, or have I just missed it for the past few years. (I thought the Components window always showed all the sub-components as well)

I see that the recursive message cam because I clicked on a component while I was already editing the same component.

But at least I can find Component #41 now - which is what I was trying to locate.

Thanks again...

Been in SketchUp as far as I've used it ... 5/6.

You can also access the property via the API: http://www.thomthom.net/thoughts/2012/02/definitions-and-instances-in-sketchup/#8220internal8221-components

The Outliner is a far more efficient way of finding nested components/groups, right clicking over the selected item in the Outliner offers all of the usual context-menu items.
Using View > Component Edit > Hide rest of model etc lets you see what's what too...A little better component naming would be helpful too

Thanks TIG - A client grabbed this from the 3D warehouse and marked the whole thing as a light - which was making way too many individual light sources. (Not just the rice paper, but also all of the hardware in the light)

I told him he should re-insert the rice paper as a single surface, (it is 26 separate surfaces in the 3D Warehouse model), and then make it into a single light for faster processing. But without the outliner, (which I did not think to use), or the expand function, it was hard to see just what was going on.

It could certainly be made from far less geometry and sub-parts - it's a light-fitting, who's ever going to be so close to see it's inner workings - a prime example of over-detailing an object

I see there is an internal? to check for an internal component in Ruby.

Is there any way to mark a component being used as a sub-component as internal when I am creating a component with ruby?

Unfortunatly no. I've requested this, as it'd be very useful for organizing a model.

...
BUT provided the sub-components are only used inside a main-component [i.e. they have no instances in their own right] you could try this way...
Save the main-component externally [use the 'TEMP' folder etc], rename the original and any sub-components as 'scrap'.
https://developers.google.com/sketchup/docs/ourdoc/componentdefinition#save_as
Keep track of any instances of the main-component's definition.
Reload the TEMP skp back into the model - it should take it's 'original name' [rename it otherwise].
https://developers.google.com/sketchup/docs/ourdoc/definitionlist#load
Erase the TEMP SKP to tidy up [ File.delete(tempskp)].
Set every original main-component instance.definition=newdefn to use this newly imported replacement.
The newly imported component now has its own 'internal' sub-components.
At the close of play do a ' .clear!' on each of the unused ['scrap'] main-component and sub-componnet definition.entities in turn - when the model.start...commit_operation block closes they then are auto-deleted as empty definitions.
Now any 'internal' wholly sub-components are no longer listed in the unExpanded Component Browser > Model panel.
They will appear in the Outliner as before...

The other day I put together a little tutorial about internal and external components: http://www.sketchucation.com/resources/tutorials/36-intermediate/115-internal-external-components

This "recursively defined model or component" is not in that tut but from the "preamble" What is a component, it is obvious that you cannot place a file into itself.

thomthom

Only thing about the article - at the end, about scaling - it seem to suggest that you scale a model to a match the incorrect scale of an imported component? Or did I misinterpret that?

Gaieus

I did not mean to say that there. I'll revisit and see if there is anything to misunderstand, thanks.
