This tool establishes a 3D reference with its X and Y axes on a given plane. The Z axis will then be perpendicular to the plane. The origin and X/Y direction of the resulting reference system can be set in a number of different ways, ax explained below.

Setup

3D coordinate system

• Reference - a 3D reference tool

Plane to project onto

• Tool - tool delivering a plane
• Result - tool result to use
  • Note - most 3D tools will deliver an XYplane result - this can be convenient to project onto.

Item to project onto plane

A tool reference, a line or a line defined by two points can be projected onto the given plane. The projection can be done using one of several options:

Tool reference - project a reference system onto the plane

• Tool - a tool with a reference system
• Child refsys origin - where to place the resulting origin
  • Origin nearest point on plane - at the refsys origin's nearest point on the plane
  • X axis/plane intersection - where the refsys' X axis intersects the plane
  • Y axis/plane intersection - where the refsys' Y axis intersects the plane
  • Z axis/plane intersection - where the refsys' Z axis intersects the plane
• Child refsys direction - direction of the resulting refsys' X axis
  • Projection of X axis - along the projection of the refsys' X axis
  • Projection of Y axis - along the projection of the refsys' Y axis
  • Projection of Z axis - along the projection of the refsys' Z axis

Line - project a line onto the plane

• Line tool - a tool with a line result
• Line result - tool result to use
• Child refsys origin - where to place the resulting origin
  • Line start nearest point on plane - at the line start's nearest point on the plane
  • Line end nearest point on plane - at the line end's nearest point on the plane
  • Line/plane intersection - where the line intersects the plane

  Note - the refsys' direction will be with the X axis along the line projection

Points - project to points onto the plane

• Point 1 tool - a tool with a point result
• Point 1 result - tool result to use
• Point 2 tool - a tool with a point result
• Point 2 result - tool result to use
• Child refsys origin - where to place the resulting origin
  • Point 1 nearest point on plane - at point 1's nearest point on the plane
  • Point 2 nearest point on plane - at point 2's nearest point on the plane

Note - the refsys' direction will be with the X axis along the projection of the line from point 1 to point 2
