How to create a coincident plane from a CAD face


Learn how to create a coincident Plane from a CAD Face.


The Plane needs a Centroid and two non-linear axes (can't be parallel). We will utilize the Edges and Vertices of the CAD Face to create the Plane

Note: The part we are starting with is already imported, and the face has been extracted from the part. Download the example file to follow along. 

1. Add two Line Segment blocks to the workflow. Using control points found in the CAD Face properties, we can define the Line Segments to the surface.


2. The last step is to add a Plane block. The origin can be any vertex on the CAD Face surface. The axes are defined by each of the line segments' directions. 



And that’s it! You’ve successfully created a plane that is coincident with a CAD Face

    (1) Extract Origin Point from "Origin" properties that is extracted from the CAD face in the first step.
    (2) Extract control points (same as above)
    (3) Calculate the vector between the origin point and your "X" point and the vector between the origin point and the "Y" point. Do this by using the vector2vector subtraction block. Use these two new vectors, call them "dX" and "dY", for the input of X and Y in the plane block.
