SpaceClaim has a pretty neat feature of being able to import pictures. This comes in useful when trying to compare a picture of a part cross-section to the CAD. Rough dimensional analysis can be done. To take it a step further, the model could be updated so that the contours match the cross section picture.
Other uses for it is to help 'inspire' CAD when the models are created from scratch. More accurate proportions and curvatures could be represented in the model. An example of which is shown below where the vitreous humor and crystalline lens of a Wikipedia picture was approximated.
The Scary Eye
We could insert the picture here:
Insert Picture File here
With the picture imported, it could be used as a background image for tracing splines to recreate key features. For example, two areas were recreated here:
Adding Splines to Create Areas
Areas at Different Plane from Picture
With that, a 3D eye model was modeled after a picture. It is a world better than having me create the volumes free-hand. Happy Halloween!
