To Define the Lattice Region
Define the lattice region as part of the procedure for creating beam-based, 2.5D, formula-driven, custom, and stochastic lattice.
1. Click
Engineering >
Lattice. The
Lattice tab opens.
2. Click the Lattice Region tab.
3. Select one of the following options:
◦ To add an internal lattice, and not convert the solid part to lattice, clear the Replace solid with lattice check box, and set up the following parameters:
1. To define an internal volume for the lattice by selecting a volume region, click the Lattice volume region collector, and hold down the CTRL key while you select the surfaces that bound the lattice propagation. You can click Details to open the Surface Sets window.
The selected surfaces should create a closed volume. The arrow should point toward the inside of the volume.
|  When you replace a solid with lattice, you cannot choose the lattice volume region. |
2. To ignore openings in the surface, select Patch open areas.
◦ To convert a solid part to lattice, select the Replace solid with lattice check box and set the following parameters:
▪ To exclude the shell from the lattice, clear Create shell.
▪ To include the shell of the part in the lattice, select Create shell and set the following parameters:
1. To set the shell thickness, type a value next to Thickness.
2. To select the side of the lattice on which to create the shell, next to Shell side, select Inside or Outside.
3. To exclude shell surface from the lattice, under Excluded shell surfaces, select the surfaces to exclude.
4. To process the lattice without geometry that fails to intersect or detach, select the Skip failed geometry check box.
This option is not available for formula-driven lattice.
5. To orient the lattice cells, click the
Orientation collector, and select a coordinate system or a build direction analysis. If you select a build direction analysis, the lattice z-direction coincides with the build direction. If the model contains a build direction analysis feature, it will be used automatically as the direction for the lattice. See
About the Build Direction.
6. To change the default location of the first lattice cell, click the First cell position box, and in the graphics window select a coordinate system, vertex, or datum point.
