1. CROWNE PLAZA ANAHEIM, CA April 24-25, 2014 PACIFIC COAST Create a Parametric Ionic Column from Start to Finish Paul F. Aubin

2. April 24-25, 2014 CENTRAL STATES SCOTT CONFERENCE CENTER OMAHA, NE Paul F. Aubin Create a Parametric Ionic Column from Start to Finish

3. TBD 2014 PACIFIC COAST SAN FRANCISCO, CA Will update this page when venue is determined

4. Objectives Constructing the Ionic volute Creating the Ionic capital using the volute profile Building the scrolls and completing the capital geometry

5. Some assumptions and prerequisites Create a new family from a pre-defined template. overall settings and parameters including the category Are familiar with various templates free-standing, hosted and face-based Reference planes Can add and modify them Add dimensions Set up simple labeled parameters Importance of “flexing” often

6. Approach Basic Box Sweeps and Swept Blends Scale and Proportion Base Diameter Decimal Units Level of Detail

7. Coarse Scale

8. The Ionic Volute It’s that curly thing 24 flexing arcs! Many sources Using a nested detail item family rig

9. Nested Detail Item Rig

10. Creating the Volute Profile Open the Starting file Position the nested rig (already in the file) Align and lock Link up Base Diameter Flex Begin drawing arcs Align and lock center and endpoints Flex, Flex, Flex…

11. Reference Planes and EQ Instead of Trigonometry, we use Equality constraints And nested Detail item rigs Saves on formulas Better performance

12. Second verse, same as the first Creating the inner edge of the fillet New instance of the Detail rig Repeat process of adding arcs FLEX!

13. Finish Volute Profiles Complete the profile by closing the shapes Save Save As to create a second (Simpler) one Flex

14. Capital Family Reuses pieces from a Doric Reconfigure moldings Adjust voids Flex

15. Making the Sweeps Use a sweep so we can use the profile Two sweeps back to back Simple straight line paths

16. The Scrolls Sweep and Swept Blend Profiles use Splines Splines maintain proportions when scaling! Flex

17. Complete the Scrolls

18. One more sweep Use a spline path Add parameters FLEX!

19. Complete the Order
