Transform Surfaces (3-D)

3-D Standard > Tools > Surface

The functions of this menu enable you to transform surfaces by moving, rotating, mirroring or scaling them, with a distinction being made between:

• Retain surrounding surfaces (Retain direction)

Only the surface boundaries are adapted.

(1) Surface, (2) Displacement vector, (3) Adjustment of the surface boundaries

• Retain facet boundary (constant surfaces)

Neighbouring surfaces are adapted by means of inclination or triangulation.

(1) Surface, (2) Displacement vector, (3) Adjustment of the neighbouring surfaces by means of inclination

Retain surrounding surfaces	Retain facet boundaries
		Move (direct) Moves the surface by specifying two points
		Move surface, with vector Moves the surface by specifying a displacement vector
		Rotate, about edge/2 points Rotates the surface by specifying edge + points
		Rotate about axis Rotates the surface about an axis
		Move+Rotate Moves and the surface simultaneously
		Similarity transformation Moves, rotates and scales the surface
		Scale Scales the active object or changes volume, mass or surface area
		Last transformation Applies the transformation that was last applied to a surface to the selected surface
		Change surface radius Changes surface radiuses of analytical cylinders or polyhedral cylinders by specifying the new value
		Change surface radius, via point Changes surface radiuses of analytical cylinders or polyhedral cylinders by specifying a point on the lateral surface.
		Change edge radius* Reduces/enlarges circular or polyhedral surfaces by specifying the new value
		Change edge radius, via point* Reduces/enlarges circular or polyhedral surfaces by specifying a point on the medial surface

* These functions are only available for Transform surfaces, Retain surrounding surfaces.

Clicking the arrow below Surface icon opens a pull-down menu with further surface functions.

Please note:

• The functions work in a similar way to the corresponding Transformation functions for parts.
• The Surface selection menu is automatically displayed for selection of the surfaces to be transformed. However, this is only the case if the Always display window option was active when you last exited the Surface Selection menu. Once you have called the function, you can also use the right mouse button to activate the Surface menu.
• You can also use the cursor to move surfaces dynamically. Simply enter 0 instead of the length of the displacement vector.

• When moving or rotating surfaces, changing topologies will be considered. These functions can also be applied to freeform surfaces.

Example: Moving of a facet

Example: Rotating of a facet
