STRUCTURE MENU 543
Scale
If this option is enabled, the relative scaling factor changes only by the value entered here when scaling
objects, point quantities, surfaces and so on.
Rotate
When this option is enabled, the chosen element can be rotated only in steps, as set here. Thus a value
of 10° allows a rotation of the element in steps of 10°, 20°, 30° and so on.
Texture
This is a percentage that, when enabled, gives the increment by which you can move and scale
textures.
Tool
This setting is relevant to all the interactive tools in the Structure menu. If you enable this option,
change the value to 10 and then extrude a surface, the extrusion will take place in steps of 10 units.
Together with the various modeling tools, this allows for accurate modeling.
Edit Spline
Before you can apply any of the tools or commands on the Edit Spline sub-
menu to a spline primitive, you must rst make it editable by choosing
Functions > Make Editable.
Hard Interpolation
This command is not available for B-Splines.
Before. After.
This command switches all selected points to hard interpolation. If no points are selected, all points of
the spline are automatically changed to hard interpolation. Hard interpolation means that the tangents
of the appropriate points are set to a length of zero.
