Right now I am editing someone else's model of a plant. I want and to map texture on all of the leafs at once, but they are all groups.. I would practically had to place every single leaf all over again as a component instead of a group.
And it did happened to me few times that I just forgot to make my group a component, and than I would lose the option to edit all at once. I guess you are just more careful when you work on your models 
Well it makes 120 different components.. which again does not help me.. I need it to convert all of the same groups to one type of component so I can edit them all at once
Hi all,
I was wondering is there any way to convert certain groups that are repeated in model to components? For example I forgot to change certain group to a component before multiplying it and now I have 120 groups in model (entity info says there are 120 of these groups in model).. I need to edit them all as they were components, but now it is impossible.. or maybe there is a way? Please help.
Yes, it really is a useful tool, I'm just thinking about how much it could shorten the modelling process for me in some situations. Thanks again!
Box,
Thanks a lot. I think that is the plugin I've been looking for. 
TIG,
This is exactly what I wanted to do. I guess the verb I've been looking for is "wrap". I wanted to wrap the surface with the curve as it were a texture on the curved surface.
I guess there is no easy way of doing it.. OK so, could you recommend me an UV mapping tool for this? The most challenging thing I've done with texture mapping in Sketchup is projecting so I don't know how to wrap texture on face.
OK.. so this is what I want to draw in Sketchup. A curve that is in vertical plane (which will later define the "not fixed" gradient of the slope, and than I want it to "I don't know the verb for this" on the curved surfaces.
Practically It would be the opposite of unfold tool.
OK, this is really clever
Normally, I would have intersect faces and than delete the unneeded leftovers. It's great, thanks.
However, this is still not the geometry I had in mind. Please read the plastic explanation I have with wallpaper in my second post in this topic. I need the curve that is in one plane to be "rolled over" a curved surface.
I will make a new sketch soon, since my language capabilities are limited.
Thanx for responding.
Sorry, but that is not what I had in mind.
I've attached a sketch of the closest thing I can make with basic tools in few seconds. It's an intersection of two curved faces resulting in 3D curve. The problem is that I don't want a real intersection. I'm not sure how to explain it using correct geometrical terms so I'll explain it like this:
Imagine I've sketched a curve on wallpaper and then I stick that wallpaper on the curved wall. So, the curve on wallpaper that was drown in one plane is now ______ (I don't know the verb for this action and it's not projected since it would be a intersection) on curved surface.
So, basically I need a 3D curve, not really a face. I hope I was able to explain this now.
