Pick Data Points: Used to define new segment by supplying the data points either in 3D or 2D.
3D points in active coordinate system When on, floor segment being traced uses active coordinate system. The data points supplied follow desired orientation and inclination. Using AccuDraw ensures accurate result.
2D points on plan view When on, allows setting required Elevation, Pitch angle and Orientation in plan view.
  • Elevation – Used to elevate the floor segment above the plane it’s being traced in the active floor. The elevation value is supplied in default unit.
  • Pitch angle – Used to tilt the floor segment in a desired angle. The pitch angle supplied in default unit determines the tilt of the floor segment.
  • Orientation – Used to set the orientation of the floor segment. The orientation angle determines the alignment of the edge of the floor segment.
