Analyzing Curves and Surfaces

  This chapter deals with curve and surface analysis. Within the FreeStyle Shaper, analyses are elements that need to be explicitly deleted if you do not wish to keep them.
  The FreeStyle Dashboard tools do not affect the analyses.
Selecting curves and surfaces in implicit mode: CCK types between two curves and/or surfaces.
Check connections between surfaces: select two surfaces, specify the type of analysis (distance, tangency, curvature) and set the analysis parameters.
Check connections between curves: select two curves, specify the type of analysis (distance, tangency, curvature) and set the analysis parameters.
Checking connections between curves and surfaces: select one curve and one surface, specify the type of analysis (distance, tangency, curvature) and set the analysis parameters.
Analyze the distance between two sets of elements: select a surface and a target element, specify the analysis mode, type, and display parameters.
Use dynamic cutting planes: select a surface, specify the cutting planes orientation, numbers, spacing, etc.
Analyze using highlight lines: select a surface, and specify the highlight type.
Perform a curvature analysis: select a curve or surface boundary, specify the curvature comb parameters (spikes number and length, orientation, etc.). 
Perform a surfacic curvature analysis: select a surface and specify the display parameters.
Perform a draft analysis: select a surface and specify the display parameters.
Map an environment on a surface: choose the mapping to be reflected onto every element.
Analyze using isophotes: specify the isophotes number, thickness, color, and position.
Analyze using highlights: click the ACA Highlight icon and define stripes or grid lines density, thickness and sharpness.
Manipulate light sources: click the icon, define the mode and manipulation parameters
