How to import and use a Point Map

Objective:

Learn how to import and use a point map.

Applies to:

  • Fields
  • Ramping

Procedure:

1. Set up your CSV file

If you are importing a Scalar Point Map, ensure your format is: X, Y, Z, S where S is the desired value at each point.

If you are importing a Vector Point Map, ensure your format is: X, Y, Z, U, V, W where The U, V, W represents the vector at each point.

 

2. Import the Point Map

    • Add an Import Scalar Point Map block (or Import Vector Point Map block)
      • Set the file path
      • Choose units to correspond to the points
      • Optional: Set a scale for the Point map

3. Convert the Point Map to a Field

This step is necessary to convert the point or vector data into a field. The field can then be used to edit your desired part.

4. Optional: Use the field to create a Ramp

One of the most popular methods with importing scalar point maps is to create a Ramp and use this to vary a parameter. 

    • Add a Ramp block
      • Input the Field from Point Map block as the Scalar Field
      • Set the In min and the In max to correspond to the imported 'S' values from your CSV. Don't add units to these values
      • Set the Out min and the Out max to correspond to the parameter you want to vary. If you are varying thickness, for example, add 'mm' to these values
      • Set the Continuity to your desired option
    • Insert the Ramp block into the parameter you want to vary. Ex. Inserting the Ramp into the Thickness input of a Periodic Lattice Body block.
