SpaceClaim is a legacy product from Ansys and provides capabilities for modeling, geometry cleanup, drawing sheet, sheet metal operations, reverse engineering etc. 

Discovery on the other hand provides you most of these geometry related features with additional front up simulation helping you explore design variation, optimize and accelerate your product design cycle.
