Doc:Reference/Panels/Editing/Curves/Curve and Surface

From BlenderWiki

This panel appears in the Editing Context panel group which is accessed using F9 or clicking button in the Buttons window. This panel has two different appearences depending on what type of object is selected. For Text type objects the "Path" fields are not visible; see Fonts below.

[edit] Curves

• UV Orco - Calculates an undeformed Curve/Surface to be used as reference for "Orco" texture coordinates.
• PrintLen - The length of the path is printed in Blender units.
• Centr - Each ObData has its own local 3D space. The null point of this space is placed at the Object centre. This option calculates a new, centred null point in the ObData. This may change texture coordinates.
• Centre New - As above, but now the Object is placed in such a way that the ObData appears to remain in the same place.
• Centre Cursor - The new null point of the object is the 3D-Cursor location.
• PathLen - The length of the Curve path in frames, if there is no Speed Ipo.
• CurvePat - Specifies that the Curve becomes a path. Children of this Curve now move over the curve. All Curves can become a path, but a 5th order Nurbs curve works best. It has no problems with movement and rotation discontinuity. This option is an alternative to a Follow Path constraint.
• CurveFol - The Curve path passes a rotation to the Child Objects. The 'Tracking' buttons determine which axis the path follows. In EditMode, horizontal lines are also drawn for a 3D curve. This determines the tilt, which is an extra axis rotation of the Child Objects. The tilt can be changed using the T. Curve paths cannot give uniform perpendicular (aligned with the local Z axis) rotations. In that case, the 'up' axis cannot be determined.
• CurveStretch - ?
• PathDist Offs - ?
• DefResolIU - The standard resolution in the U direction for curves. Set Assigns the value of DefResolIU to all selected curves.
• Back - Specifies that the back side of (extruded) 2D curves should be filled.
• Front - Specifies that the front side of (extruded) 2D curves should be filled.
• 3D - The curve may now have vertices on each 3D coordinate; the front and back side are never rendered.
• Width - The interpolated points of a curve can be moved farther apart or brought closer together.
• Extrude - Gives the line width. The width can be specified.
• Bevel Depth - ?
• BevResol - The resolution of the standard bevel; the bevel eventually becomes a quarter circle.
• BevOb - The "bevel" Object. Fill in the name of another Curve Object; this now forms the bevel's profile. For each interpolated point on the curve, the "bevel Object" is, as it were, extruded and rotated. With this method, for example, you can create the rails of a roller coaster with a 3D curve as the base and two small squares as bevels. Set the values ResolU of both Curves carefully, given that this bevelling can generate many faces.
• TaperOb - The "taper" Object. Fill in the name of another Curve Object; this now forms the bevel's tapering profile.
