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.
Note: Your table should not have any headers, just the data points.
| Will not import correctly because of header | Will import correctly |
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
- Add an Import Scalar Point Map block (or Import Vector Point Map block)
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.
-
- Add a Field from Point Map block
- Insert the imported point map block from Step 2.
- Choose the Interpolation and Extrapolation options
- Add a Field from Point Map block
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.
- Add a Ramp block
