I have drawn my quadcopter in Google Sketchup and exported the design as a .wrl file. I opened it using V-Realm Builder. Everything is nice and all of the components are grouped (in Transform trees) as desired but the problem is that there are so many shapes (Shape nodes) under the children of each Transform node. I want every component to be one shape like the vrtoff.wrl example. How would I do so? How would I put all the shapes to one geometrical shape?
