[b]Hi John, What a great model well done ,but may i ask how big it came out and was it done using plans . Your a credit to the program John
Regards Phil

If i may ,can i give you our future experts ( trust me it won't take long ) tips to help them along

1/ Accurate inferencing, To me is the corner stone to clean non hair pulling out experiences in sketchup ( Zoom zoom to see were your putting that line)

2/ COPLANER If that face will not fill in after 10 minutes ( and i have been there) its not flat ! If there are two lines very close together where there should be one ( you know, those lines that look alittle thicker that the other lines), then the party on its the way to pair shape city Ha ha.

3/ Work cleanly and and erase those lines that should not be there ( the lines that keep flashing puppy eyes at your inference engine) ,and your clinical approach will reward you , in not wanting to get off your computer ,rather than throwing it out the window .
Enjoy Phil

HI, i used the drape tool in a small section and that stopped the crashing ,but it did not transfer very well leaving spaces. So then i pulled the design through the ring and intersected with model and deleted unwanted geometry. .I then used fredo's pull push tool and it did not seem to bad . i did not pull it the whole through but have a look at the file i sent back .
Regards Phil
