Manage Appearances—Opens the Appearance tab.
Manage Appearances—Opens the Appearance tab.◦ Model—Displays the colors that were applied to the models in Creo Parametric.
◦ 3D Printer—Enables appearance assignment. When selected, these commands become available:
▪ 
Auto-match Colors—Automatically matches colors that are available in the 3D printer palette to the colors that were already applied to the model in Creo Parametric.

Lattice Printing Options—Defines how the lattice connects to the solid geometry.
Lattice Printing Options—Defines how the lattice connects to the solid geometry.Defines either the penetration values for lattice structures into the solid wall of the model, or how the lattice blends into the solid wall. Opens the Lattice Printing Options dialog box:
◦ Penetration into Shell
▪ Penetration—Defines the penetration depth in mm for all lattice geometry that is adjacent to a solid wall. You can see the overlapping contours of lattice and body structures in the slicing viewer.
▪ Cap beams with half sphere check box—For beams lattice, ends all beams that are adjacent to a solid wall with a half sphere that penetrates into the wall.
◦ Merge and Blend with Shell
▪ Merge lattice and shell check box—Merges formula-driven lattice with the solid walls when the lattice and the solid walls are in the same body.
When this check box is selected, and the conditions apply, then the penetration options are ignored. When these conditions do not apply, the penetration value is used instead.
Selecting this check box might result in an increase in the mass properties.
▪ Blending Intensity slider—Specifies the blending intensity between the solid walls and the formula-driven lattice. The blending intensity varies from none through the highest intensity of half of the lattice wall thickness value.
