*fix_surfaces_orientation
Flips surface normals from a selected surface (or set of surfaces) and any surfaces attached to the selection to all point in the same direction.
Syntax
*fix_surfaces_orientation surfaces orientation
Type
HyperMesh Tcl Modify Command
Description
The direction in which reoriented normals point can then be collectively reoriented based on treating the group of 2D surfaces as if they were surfaces of a 3D entity. For example, three adjacent triangular surfaces might define a tetrahedral space even if they are not actually faces of a tetrahedral entity.
Inputs
- surfaces
- The surfaces you want to make normals consistent.
- orientation
- 1 - Normals point away from the center of the hypothetical 3D element.
Example
*fix_surfaces_orientation(72,1)
If the selection includes T-intersections, the results will be unpredictable. Similarly, if the selected surfaces do not define a 3D space (such as in the case of coplanar surfaces) then the final swap of normals determined by the orientation argument may be unpredictable.
