• Parameterization
The items on this tab are available only when you enter Reparameterization mode.
◦ Reparam Curves List—Displays the reparameterization curves you have created.
◦ Reparam Soft Point—Places the reparameterization curve soft points. The options are context sensitive according to the Type of constraint you select.
▪ Type—Sets a soft point type.
▪ Length Ratio—Places a soft point at a ratio of the distance between the curve end points.
▪ Length—Places a soft point on the curve at a specified distance from the curve end point.
▪ Offset from Plane—Places a soft point at a specified distance offset from a selected plane.
▪ Lock to Datum Point—Places a soft point on a datum point.
▪ Value—Sets the soft point placement value based on the soft point type.
▪ Reference—Displays a soft point placement reference.
• Options
◦ Radial check box—Rotates cross sections radially along the guide curves.
◦ Uniform check box—Scales cross sections uniformly along the guide curves to preserve proportions.
◦ Show Trimmed Neighbors check box—Displays neighbors as trimmed surfaces.
◦ Use for 3 and 4 boundaries check box—Makes a 3-sided or a 4-sided boundary surface into a trimmed rectangle surface.
