SHOE DESIGN AND VISUALIZATION WITH RHINOCEROS
Creating a Last from a Scanned Mesh Model
The process for creating a last from a mesh generated with a scanner is slightly different
from using digitized points. You will create sections by projecting curves onto the mesh
model and then use those section curves to model the last.
Creating section curves
The Section command will create your initial curves from the mesh.
To create section curves
1 Open the file Scanned last.dxf.
The file contains a mesh of a last generated by stream digitizing with a scanner.
2 Use the Section command to generate
enough curves (8–10) to define the shape of
the last. (Curve menu: Curve From Objects
> Section)
Create the curves that correspond to the
upper surface with radial section curves.
Create the curves that define the sole
surface with section curves perpendicular
to the last’s longitudinal axis.
To refine the section curves
1 Hide the mesh. (Edit menu: Visibility > Hide)
2 Use the Split command to split each curve with the Point option at the theoretical
intersection between the sole and upper surface of the last. (Edit menu: Split)
