Hi Jeff and James,
Thanks for your feedback. The YouTube segment is very helpful in that it shows the possibility of going back and changing the geometry with the scale tool. It is a pretty elaborate flying wing, and interesting to see it from start to finish.
The segment on the wingtips is also very helpful, I will try out the soap bubble ruby. I had previously been to the PushPull site and downloaded most of the scripts there. I still do not know why 3DShapesTool does not persist after the last click. I have not found a tutorial on it.
Jeff, your question about my skill level made me try and make a rounded cube. I am not sure how to send the attachment, but am sending it anyway. I need to read up on a bit more on the basic tools, especially using exact input in the VCB that did not seem to work for me. will keep at it.
Many thanks for your feedback.
