SketchyQuestions #4: Crazy Spirals

www.sketchyquestions.com How to make some crazy spirals in Google SketchUp. 1. create CIRCLE (24 segments) 2. LINE tool to 'cut out' one of the segments of the circle 3. DELETE everything except that wedge 4. PUSH to give the wedge a thickness of 6" 5. make the wedge a COMPONENT 6. draw diagonal LINE on flat outer face of wedge 7. make diagonal line a COMPONENT 8. make wedge and line a new (3rd) COMPONENT 9. array component 360º to create "disc of wedges" (ROTATE/COPY the first wedge 15º, then type 23x to get the rest of them) 10. array disc of wedges up (SELECT everything, MOVE/COPY first disc 6", then type 11x) 11. SELECT a diagonal line from the first level of discs (doesn't matter which one), then follow the diagonal all the way up SELECTING them as you go 12. DELETE everything except for the components selected in step 11 time 1:20 13. MOVE/COPY "half spiral" up 6' 14. ROTATE 180º (360º spiral should now be complete) 15. EXPLODE everything once (wedge and line are separate components again) 16. DELETE all wedge components (only line components remain) 17. array spiral up (SELECT everything, MOVE/COPY first one 12', then type 12x) time 2:42 18. create a surface (vertical half circle in this case but does not have to be) 19. SELECT everything 20. EXPLODE everything (do NOT deselect anything, this creates the path used in step 21) 21. use FOLLOW ME tool on half circle surface 22. DELETE construction path if wanted crazy spiral is complete
