Creates a interpolated surface by fitting b-splines to each selected point group and then lofting the b-spline to create a surface. This function will take into account and compensate for points with probing offsets, making it very helpful for laser tracker users.
The expectation is that each included point group will be laid out as a cross section. Using the Geometry Trigger measurement profile with either a tracker or an arm will facilitate this process.
SA's geometry has graphical extents defined in the objects properties dialog. These control the display of the object but do not directly influence point to object analysis operations as objects are handled as infinite objects. Building surfaces from an option can serve either of two objects:
It can constrain the analysis of an object to preset size, this size is drawn from the graphical decapitation of the object
It also offers an confinement export option to other CAD applications.
Surface from Object construction can also be accomplished by right-clicking on an object and selecting Make Surface from Object.
