Good enough. If it's a simple thing like this and can be handled in a couple of clicks with native tools I usually don't bother using an extension but there's often more than one way to accomplish things in SketchUp.
No need for the parallel placement if you aren't projecting the texture. I'm guessing this texture of yours is some banding as might be used on a musical instrument. In real life it would be about veneer thick and would be wrapped around the body of the gitbox or whatever. You'd use projection if you wanted to show how a pattern of glued up blocks changes when they are turned on a lathe.
That is beautiful. I actually had the tool collection but there were so many of them that I missed this one. And the function i needed only scratches the surface (pardon the pun) of Thrupaint and that only scratches the surface of the collection. Amazing.
If can have groups instead of some components it will also be faster. So, for big models "good" modeling practices (I know Dave will kill me now... 😄) it's better to start off by groups and not components.
(Before you kill me Dave) Rich O'Brien made a tree model with all leaves as components and it worked slower... Now I can't find it and I can't be sure if the leaves were pure geometry or groups...
Textures are embedded in the model but you have a couple options.
If you select an image editing app under Preferences > Applications, then you can right-click the material in the Material Browser and open it in your selected app right from SketchUp.
You could also right-click the material in the Material browser and select "Export Texture Image", and then edit it in an external app, then apply the editor material.
