TechTip: Avoiding incorrect calculations of the surface normals
Selection Mode “Faces”
This problem can be solved with the help of the selection mode “Faces”, which can be found in the drop-down menu at the top of the window (Fig. 2). This selection mode allows to select entire surfaces of the 3D object (see Fig. 3 & Fig. 4). With the option “Recalculate Normals from Selected” the surface normals can now be recalculated relative to the selected surface (Fig. 5).
Adoption of the orientation of the surface normals
Next, the direction of the surface normals must be adapted to the orientation of the Z-axis of the TCP. This can be done by using the option “Toggle Orientation Normal” (see Fig. 6 & Fig. 7) so that the surface normals point in positive Z-direction.
After exiting the CAD2Path tool, the path can now be traversed as long as every point along the path is in the working space of the robot (see Fig. 8).
