How to easily change and replace components with more detailed ones.

Now you will reference more detailed models and profile curves to make a more true to life and complex rotunda.

A warning: Cornices or any shapes that create long and thin polygons for rendering will really bog down doing anything in Rhino. For instance the entablature curve profile I have provided you creates a very complex surface for Rhino's mesher. So always keep your rendering settings on ** until the final render. The other provided column is based on the tower of the four winds at Athens in proportion. It is more detailed and only missing the top ornaments. The entablature profile is created from one of the many specifications of Asher Bejamins classical architecture. But this matches quite well in proportion and style with the column from the four winds.

1. Copy and paste the left hand column below
! Merge
! Circle
! merge
! selmesh
This command begins the file merge command.
This tells rhino what file to merge into the present one.
This creates a circle for the Entablature profile to sweep around.
This is the cplane x,y,z coordinate center point of the circle.
Tells Rhino to draw the circle using radius.
This is cplane x,y,z coordinate of the radius of the circle.
This selects both curves.
This sweeps the entablature around the circle
This completes the command.
This command begins the file merge command.
This tells rhino what file to merge into the present one.
This moves that recently imported or merged file.
The place to move the part from in this case world 0,0,0.
This moves the part to these world coordinates.
This selects all meshobjects, an easy way to select the columns.
This command performs a polar array.
This is the origin point for beginning the polar array.
This tells how many items or copies to make in the array.
This tells the angle in which to distribute the columns.
This finishes the command.
This deselects all selected objects.

2. In Rhinoceros click the command paste Icon
3. Quick or full render the model

4. Select the orignal provided curve profile
5. click the Invert Selection icon or type ! Invert at the Rhinoceros command prompt.
6. Delete the inverted selection. You should only have the the original provided curve profile in the workspace.
