Objective:
This example creates a bumpy texture on the surface by generating a series of random spheres.Applies to:
- nTop
- Surface textures
- Lists
Procedure:
- Extract the CAD surfaces where you want to add bumps, save them in a CAD Face List.
- Use Mesh from CAD Body on the Face List.
- Remesh Surface.
- Merge Meshes to join the list into a single mesh object. This step is unnecessary if starting with a single CAD face.
- Add a Random Points on Mesh block and enter the number of points you want to create. These points will locate the origin of each sphere.

- Add a Sphere block and input the Point List into the Center Point Input. Be sure to change the block type to Implicit Body List.
- Boolean Union the Spheres to itself to get rid of the lists.
- Boolean Union the Spheres with the original body to complete your part.
