Objective:

Learn how to use the Mix and Ramp block to blend two different types of TPMS together.

Procedure:

1. Set up the part and variables

• • Start with any Implicit Body and name it "Body Shape"
  • Open the Properties of the Implicit Body, and drag the Bounding Box chip into the Notebook to create a Variable of this parameter (this will be used in the final step)

2. Set up the Gyroid details

• • Add a TPMS block, name it "First Gyroid"
    • Insert "Body Shape" into the Body input
    • Choose Cell size as 5 x 5 x 5 and Fill type as Gyroid
  • Add a TPMS block, name it "Second Gyroid"
    • Insert "Body Shape" into the Body input
    • Choose Cell size as 5 x 5 x 5 and Fill type as Schwarz

3. Set up the mixing parameters

• • Add a Ramp 
    • Create a Plane from Normal for the Real Field input
      • Use the Min Point property from the Implicit Body "Body Shape" for the plane origin to place it at the bottom of the part
    • Set In min: 0 mm, In max: 40 mm, Out min: 0, Out max: 1
  • Add a Mix
    • Set Real Field A to the TPMS "First Gyroid"
    • Set Real Field B to the TPMS "Second Gyroid"
    • Set Factor to the Ramp

4. Clean it up

• • Add a Set Field Bounding Box
    
    • Set the Real Field to the Mix block
    • Set the Bounding Box to the bounding box variable made at the beginning

And that’s it! You’ve successfully mixed two TPMS types together.
