The document describes various 3D modeling transactions that modify or create points and B-spline curves within a coordinate system. Key transactions include: - Creating points with various translations in the THEATRE space - Creating a B-spline curve with 7 poles for a second curve to the right - Creating another B-spline curve with 7 poles for a second curve to the left - Modifying an existing curve called curve_left by changing its poles
