The Curve Extract tool offers a fast and effective method for extracting curves from geometry tubes, cards, or selected edges. As a Groom artist, we often need to work with proxy models. When these models are thoughtfully constructed as tubes or cards, the tool can significantly speed up your workflow. All Proxy/Geometry tools in Groomer's Tool, such as Curve to Proxy Tube, Curve to Proxy Card, Curve to Proxy Twist, Hair Tube Builder, and the Braid Tool, generate geometries that is compatible and can be extracted using the Curve Extract tool.
The curve extract tool allows extraction from:
Tubes - polygons tubes that do not have end caps and are quads in equal rows/column alignment.
Cards - polygons cards that are flat and are quads in fairly equal rows/column alignment.
Edges - edgeloops of selected edges will be extracted.
Custom
CV Count: Define a custom CV count to the length of the curve extracted
# of Curves: Define number of curves to be extracted
Geo Topology
Number of CV count per curve and number of curves extracted will be based on the geo topology
Retain Curvature - Only available with Topology mode. When checked, it will keep the curvature from poly tubes.
Example: when extracting from a twisty twist (from the Twist Tool), use this mode to keep the extracted curves from smoothing.
Geo Center
Extract a curve from the average center of the tube.
Volume Fill
Fills each selected tubes with layers of curves
SubDiv: Will work on all card geometry. However, in Custom, Geo Topology, and Sides mode, the 'corners' will be rounded and the side edges will be shrunk. This is due to the subdivision process.
Traverse: Use this option to retain the edges/corners. However, depending on your card geometry, this method will not always extract successfully. In those cases, use SubDiv method instead.

Geo Center
Extract a curve from the average center of selected card(s)
Sides
Extract the side curves from selected card(s)
Hide Mesh
Enabling this option hides the mesh after the extraction
Flip Direction
If the U and V directions on a surface are incorrect, the extracted curve may form a loop. Use the 'Flip Direction' option and extract again.
If the selected edge is on a geometry border, it will extract the entire loop.
Select multiple 'single' edges on geometry to extract edgeloops.
