Performing Operations on Shape Geometry

Wireframe and Surface allows you to modify your design using techniques such as trimming, translating and rotating.

Join geometry: select at least two curves or surfaces to be joined.
Heal geometry: select at least two surfaces presenting a gap to be healed.
Untrim an element: select a split element, and click the icon.
Disassemble elements: select a multi-cell element, and choose the disassembling mode.
Split geometry: select the element to be split and a cutting element.
Trim geometry: select two elements to be trimmed and specify which side of  element 
Create boundary Curves: select a surface's edge, set the propagation type, and re-define the curve limits if needed.
Extract geometry: select an element's edge or face and click the icon
Translate geometry: select an element, a translation direction (line, plane or vector), specify the translation distance
Rotate geometry: select an element, a line as the rotation axis, and specify the rotation angle
Perform a symmetry: select an element, then a point, line, or plane as reference element 
Transform geometry by scaling: select an element, then a point, plane, or planar surface as reference element, and specify the scaling ratio
Transform geometry by affinity: select an element to be transformed, specify the axis system characteristics, and the enter the affinity ratio values
Transform geometry into a new axis-system: select an element to be transformed and select the reference and the target axis systems
Invert geometry orientation: select the Insert > Operations > Invert Orientation menu item, then the surface or curve whose orientation is to be inverted, click the orientation arrow, and click Invert Orientation again to accept the inverted element.
Create the nearest sub-element: select the Insert > Operations > Near menu item, the element made of several sub-elements, then a reference element whose position is close to the sub-element to be created
Extrapolate curves:  select a curve endpoint then the curve itself, specify the extrapolation limit (length value or limiting surface/plane), and specify the continuity constraints (tangent/curvature)
Extrapolate surfaces: select a surface boundary then the surface itself, specify the extrapolation limit (value or limiting surface/plane), and specify the extremities constraints (tangent/normal)
