To Add Lattice
1. Click Engineering > Lattice. The Lattice tab opens.
2. To select the type of lattice, click Lattice Type and select 3D or 2.5D.
3. To define which direction the Z axis of the cell is aligned with, select X Direction or Y Direction.
4. To select how the lattice cells are propagated in the internal volumes, from the propagation list , select one of the following:
To add lattice cells one after the other in straight lines and layers, click Regular.
To add lattice cells in a circular pattern, click Quasi-radial, and type a value for Base Cell Number.
To add lattice cells in herringbone structure, click Herringbone.
 
* Herringbone propagation requires a non-zero skew angle.
5. To toggle the lattice representation, in the representation list , select Simplified, Full Geometry, or Homogenized.
Full geometry representation requires more resources and might cause the system to be slow, particularly when the lattice contains a large number of lattice cells.
6. To set the size of the lattice, type the value in the scale box and press Enter. This value is relative to the current size of the cell.
7. Click References. The References tab opens.
8. Select one of the following:
To convert a solid part to lattice, click Convert Solid and on the References tab, set up the following parameters:
To exclude the shell from the lattice, clear Keep Shell.
To include the shell of the part in the lattice, select Keep Shell and set up the following parameters:
1. Set the Thickness of the shell.
2. Select the Shell Side.
3. Under Excluded Shell Surfaces, select the surfaces to exclude from the lattice.
To add an internal lattice, and not convert the solid part to lattice, clear Convert Solid and set up the following parameters:
1. To set the boundaries of the lattice propagation, click Bounding Surfaces, hold down the CTRL key and select the surfaces that bound the lattice propagation. You can click Details to open the Surface Sets window.
 
* When you choose to convert solid, you cannot choose the bounding surfaces.
2. To ignore gaps in the surface, select Patch Open Areas.
9. To change the default location of the first lattice cell, click the First Cell Location box and in the graphics window click a coordinate system.
10. For both 3D and 2.5D lattice types, in the Cell tab, define the structure of the cells.
11. For 3D lattice type, in the Beam tab, define the structure of the beams.
12. Click .
