Note: Editing the mesh thickness property should be performed when only a fill or Fill+Pack analysis is required. The analysis accuracy will be compromised if a Cool analysis is run anywhere in the sequence.
Select the entities whose thickness you want to change.
Right-click on a selected entity and select Properties... from the pop-up menu. The Part surface (Midplane) dialog appears.
Select the Part Surface Properties tab.
Select Flat in the Cross-sectional shape drop-down list.
Enter the required thickness value, and click OK.
Note: If you select a cross-sectional shape other than flat, click Edit dimensions..., enter the required values in the Cross-Sectional Dimensions dialog, and click OK twice.
