When exploding groups/components, the lines and faces adopt the parent layer/tag

I could be mis-remembering, but I don’t think previous versions of sketchup used to do this, but when I explode groups or components the lines and faces adopt the parent tag.

As I model using the untagged for all loose geometry, and only apply tags to the groups/components, this setting conflicts with this logic, in so much as sometimes I use a group from another tag to start something new, and when I explode it to begin, I have to be careful to reassign the exploded data back to untagged or the data ends up on a tag that is different to the new parent tag, and this can cause problems with scene management later what with un-expected lines and faces being on tags within groups on other tags…

I was just wondering if this has always been the case! And if not, when and why was it introduced, and is there a setting anywhere, or a plugin that would let the user decide what to happen to lines and faces when exploded from a group that is on a parent tag – back to layer 0 or now called untagged…

It’s not the end of the world, and I am sure there are benefits for it doing what it does to instead of what I want it to do !

many thanks,

Tricky tricky … didn’t notice until you mentioned it (o.0) thanks for the heads up!

Has always been that way.


same with materials, since we’re at it.

make a cube, group it, paint it blue, the cube is blue, but the faces are still neutral.
now explode the group, the faces are now blue.

exploding a group or component will (and always has) transfer properties to the elements inside if it can (if they don’t already have their own properties)

yeah, the way I see it, it allows you to maintain a certain model / scene integrity even if you (accidentaly) explode a group. the content will try to behave as the former group

You can use “TIG LayerWatcher” to explode to untagged or move geometry to untagged

Thank you for all the replies, this last one looks like it could be what I am after, in particular the context menu “Explode-To-Layer0”. If I can replace my normal keyboard shortcut for explode to this, I think it will solve my dilemma without too much affect.

Many thanks for a solution numerobis, and to TIG :slight_smile:

After exploding, the entities remains selected, so even without using an extension, you can easily assign “Untagged” using the Entity info tray.
