Objectives

• Constructing the Ionic volute• Creating the Ionic capital using the volute profile• Building the scrolls and completing the capital geometry

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

Approach

• Basic Box • Sweeps and Swept Blends• Scale and Proportion• Base Diameter• Decimal Units• Level of Detail

Coarse Scale

The Ionic Volute

• It’s that curly thing• 24 flexing arcs!• Many sources• Using a nested detail item family rig

Nested Detail Item Rig

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…

Reference Planes and EQ

• Instead of Trigonometry, we use Equality constraints• And nested Detail item rigs• Saves on formulas• Better performance

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!

Finish Volute Profiles

• Complete the profile by closing the shapes• Save• Save As to create a second (Simpler) one• Flex

Capital Family

• Reuses pieces from a Doric• Reconfigure moldings• Adjust voids• Flex

Making the Sweeps

• Use a sweep so we can use the profile• Two sweeps back to back• Simple straight line paths

The Scrolls

• Sweep and Swept Blend• Profiles use Splines• Splines maintain proportions when scaling!• Flex

Complete the Scrolls

One more sweep

• Use a spline path• Add parameters• FLEX!

Complete the Order
